If you do not restore the old configuration, you may have incompatible commands representing new or changed features. Any new commands will be rejected when you load the old software version. For failover, perform this step on the active unit. This step replicates the command to the standby unit. It's important that you do not save the running configuration to the startup configuration using write memory ; this command will overwrite your backup configuration.

In this case, specify the old ASA version instead of a new version. If you cannot achieve compatibility, we suggest you do not perform a downgrade. Clearing the boot image configuration clear configure boot. Setting the boot image to be the old image boot system. Optional Entering a new activation key activation-key. Saving the running configuration to startup write memory. This sets the BOOT environment variable to the old image, so when you reload, the old image is loaded.

ASA X models only: Downgrade the software and restore the old configuration. If you need to revert to a pre You can view files in flash memory and see information about files. Enter disk0: for the internal flash memory. The disk1: keyword represents the external flash memory. The internal flash memory is the default. View extended information about a specific file:. You can remove files from flash memory that you no longer need. By default, the file is deleted from the current working directory if you do not specify a path.

You may use wildcards when deleting files. You are prompted with the filename to delete, and then you must confirm the deletion. To erase the flash file system, perform the following steps. Enter the erase command, which overwrites all files and erases the file system, including hidden system files:. You can also configure the ASA as a secure copy server so you can use a secure copy client on your computer. In passive FTP, the client initiates both the control connection and the data connection.

The server, which is the recipient of the data connection in passive mode, responds with the port number to which it is listening for the specific connection. The server does not have directory support. The lack of directory support limits remote client access to the ASA internal files.

The server does not support banners or wildcards. Unless otherwise specified, for multiple context mode, complete this procedure in the system execution space. To change from the context to the system execution space, enter the changeto system command. The performance of secure copy depends partly on the encryption cipher used. By default, the ASA negotiates one of the following algorithms in order: 3des-cbc aescbc aescbc aescbc aesctr aesctr aesctr.

If the first algorithm proposed 3des-cbc is chosen, then the performance is much slower than a more efficient algorithm such as aescbc. To change the proposed ciphers, use the ssh cipher encryption command ; for example, ssh cipher encryption custom aescbc. Optional Manually add or delete servers and their keys from the ASA database:. You can manually manage keys if desired. For each server, you can specify the key-string public key or key-hash hashed value of the SSH host. You can obtain the public key value from an open SSH client; that is, from the.

After you submit the Base64 encoded public key, that key is then hashed via SHA Optional Enable or disable SSH host key checking. For multiple context mode, enter this command in the admin context. By default, this option is enabled. When this option is enabled, you are prompted to accept or reject the host key if it is not already stored on the ASA.

When this option is disabled, the ASA accepts the host key automatically if it was not stored before. From a client on the external host, perform an SCP file transfer. For example, in Linux enter the following command:. The -v is for verbose, and if -pw is not specified, you will be prompted for a password. The following example adds an already hashed host key for the server at The following example adds a host string key for the server at In this way, you can back up and propagate configuration files to multiple ASAs.

This section lets you predefine the path to a TFTP server so you do not need to enter it in commands such as copy and configure net. Predefine the TFTP server address and filename for use with configure net and copy commands:. You can override the filename when you enter the command; for example, when you use the copy command, you can take advantage of the predefined TFTP server address but still enter any filename at the interactive prompts. You cannot have two files with the same name but with different letter case in the same directory in flash memory.

For example, if you attempt to download the file, Config. For multiple context mode, you must be in the system execution space. Optional Specify the interface through which the ASA communicates with the server. If you do not specify the interface, the ASA checks the management-only routing table; if there are no matches, it then checks the data routing table. Copy a file using one of the following server types.

When you copy a configuration to the running configuration, you merge the two configurations. A merge adds any new commands from the new configuration to the running configuration. If the configurations are the same, no changes occur. If commands conflict or if commands affect the running of the context, then the effect of the merge depends on the command. You might get errors, or you might have unexpected results. To copy a file to the startup configuration or running configuration, enter one of the following commands for the appropriate download server:.

For example, to copy the configuration from a TFTP server, enter the following command:. To copy the configuration from an FTP server, enter the following command:. To copy the configuration from an HTTP server, enter the following command:. If you do not set the image, the default boot image is used, and that image may not be the one intended. For the startup configuration, you can optionally specify a configuration file. But if you manually chose a different ASDM image that you uploaded for example, asdm When you upgrade the ASAv, you specify a different image in flash memory.

Note that if you later clear your configuration clear configure all , then the ASAv will revert to loading the original deployment image. You can upgrade the ASDM image separately. Physical ASAs—Boots the first application image that it finds in internal flash memory. You cannot use this procedure to set the ASA image. Startup configuration—By default, the ASA boots from a startup configuration that is a hidden file. The TFTP option is not supported on all models.

You can enter up to four boot system command entries to specify different images to boot from in order; the ASA boots the first image it finds successfully. When you enter the boot system command, it adds an entry at the bottom of the list.

To reorder the boot entries, you must remove all entries using the the clear configure boot system command, and re-enter them in the order you desire. Only one boot system tftp command can be configured, and it must be the first one configured. If you do not specify the image to boot, even if you have only one image installed, then the ASA inserts the asdm image command into the running configuration.

To avoid problems with Auto Update if configured , and to avoid the image search at each startup, you should specify the ASDM image that you want to boot in the startup configuration. Optional Set the startup configuration to be a known file instead of the default hidden file:. We recommend that you make regular backups of your configuration and other system files to guard against system failure. These procedures describe how to back up and restore configurations and images to a tar.

You should have at least MB of disk space available at the backup or restore location before you start a backup or restore. If you make any configuration changes during or after a backup, those changes will not be included in the backup. If you change a configuration after making the backup, then perform a restore, this configuration change will be overwritten. As a result, the ASA might behave differently. You can start only one backup or restore at a time. You can only restore a configuration to the same ASA version as when you performed the original backup.

You cannot use the restore tool to migrate a configuration from one ASA version to another. If you use clustering, you can only back up or restore the startup-configuration, running-configuration, and identity certificates. You must create and restore a backup separately for each unit. If you use failover, you must create and restore a backup separately for the active and standby units. If you set a master passphrase for the ASA, then you need that master passphrase to restore the backup configuration that you create with this procedure.

If you do not know the master passphrase for the ASA, see Configure the Master Passphrase to learn how to reset it before continuing with the backup. If you import PKCS12 data with the crypto ca trustpoint command and the trustpoint uses RSA keys, the imported key pair is assigned the same name as the trustpoint. Because of this limitation, if you specify a different name for the trustpoint and its key pair after you have restored an ASDM configuration, the startup configuration will be the same as the original configuration, but the running configuration will include a different key pair name.

This means that if you use different names for the key pair and trustpoint, you cannot restore the original configuration. To work around this issue, make sure that you use the same name for the trustpoint and its key pair. Each backup file includes the following content:. Cisco Secure Desktop and Host Scan images. Cisco Secure Desktop and Host Scan settings.

AnyConnect SVC client images and profiles. AnyConnect SVC customizations and transforms. Identity certificates includes RSA key pairs tied to identity certificates; excludes standalone keys. This procedure describes how to perform a complete system backup. If you do not specify the interface name , the ASA checks the management-only routing table; if there are no matches, it then checks the data routing table.

In multiple context mode from the system execution space, enter the context keyword to backup the specified context. Each context must be backed up individually; that is, re-enter the backup command for each file. During the backup of VPN certificates and preshared keys, a secret key identified by the passphrase keyword is required to encode the certificates.

You must provide a passphrase to be used for encoding and decoding the certificates in PKCS12 format. The backup only includes RSA key pairs tied to the certificates and excludes any standalone certificates. The backup location can be a local disk or a remote URL. If you do not provide a location, the following default names are used:. Single mode—disk0: hostname. Multiple mode—disk0: hostname. You can specify configurations and images to restore from a zip tar.

When using the context keyword to restore multiple contexts, each backed up context file must be restored individually; that is, re-enter the restore command for each file. On the ISA , you can configure automatic backups to a particular location every time you save your configuration using write memory.

Automatic restore lets you easily configure new devices with a complete configuration loaded on an SD flash memory card. Automatic restore is enabled in the default factory configuration. Set the back-up package parameters:. If you do not specify the interface name, the ASA checks the management-only routing table; if there are no matches, it then checks the data routing table. You can specify a URL or local storage. And disk3 is the SD memory card. Note that the default settings for automatic restore use disk3.

Note that the default settings for automatic restore use "cisco" as the passphrase. These settings are also used by default with the manual backup command. See Back Up the System. Note that if you use the manual backup command when you have automatic backup or restore enabled, then the system saves a backup file with the specified name, as well as the "auto-backup-asa. When you save the configuration using write memory , the configuration is automatically saved to the backup location as well as to the startup configuration.

The backup file has the name "auto-backup-asa. To disable automatic backups, use the no form of the command. Automatic restore mode restores the system configuration on a device without any user intervention. For example, you insert an SD memory card containing a saved backup configuration into a new device and then power the device on.

When the device comes up, it checks the SD card to decide if the system configuration needs to be restored. The restoration is only initiated if the backup file has the "fingerprint" of a different device. The fingerprint of the backup file is updated to match the current device during a backup or restore operation. So if the device has already completed a restore, or if it has created its own backup, then the automatic restore is skipped. If the fingerprint shows a restoration is required, the device replaces the system configuration startup-config, running-config, SSL VPN configuration, and so on; see Back Up the System for details about the contents of the backup.

When the device finishes booting, it is running the saved configuration. Automatic restore is enabled in the default factory configuration, so you can easily configure new devices with a complete configuration loaded on an SD memory card without having to perform any pre-configuration of the device. Because the device needs to decide early in the boot process if the system configuration needs to be restored, it checks ROMMON variables to determine if the device is in automatic restore mode and to obtain the location of the backup configuration.

If you need to restore the default configuration to ensure that automatic restore is enabled, use the configure factory default command. This command is only available in transparent firewall mode, so if you are in routed firewall mode, use the firewall transparent command first.

The default is disk3. The default is "cisco". These settings are also used by default with the manual restore command. In single context mode or from the system configuration in multiple mode, you can copy the startup configuration or running configuration to an external server or to the local flash memory. Back up the configuring using one of the following server types:.

Be sure that the destination directory exists. If it does not exist, first create the directory using the mkdir command. Copy context configurations or other files that are on the local flash memory by entering one of the following commands in the system execution space. Back up a context configuration using one of the following server types:. In multiple context mode, from within a context, you can perform the following backups. Copy the running configuration to the startup configuration server connected to the admin context :.

Copy the running configuration to a TFTP server connected to the context network:. Copy the output from this command, and then paste the configuration into a text file. Additional files essential to your configuration might include the following:.

Files that you import using the import webvpn command. Currently, these files include customizations, URL lists, web content, plug-ins, and language translations. Local CA user database and certificate status files. The CLI lets you back up and restore individual elements of your configuration using the export and import commands. To back up these files, for example, those files that you imported with the import webvpn command or certificates, perform the following steps.

Run the applicable show command s as follows:. Run the export command for the file that you want to back up in this example, the rdp file :. For security reasons, we do not recommend that you perform automated backups of digital keys and certificates or the local CA key. This section provides instructions for doing so and includes a sample script that you can use as is or modify as your environment requires.

The sample script is specific to a Linux system. To use it for a Microsoft Windows system, you need to modify it using the logic of the sample. You can alternatively use the backup and restore commands. To use a script to back up and restore an ASA configuration, first perform the following tasks:. Another option is to use a commercially available tool. You can put the logic of this script into such a tool. To run a backup-and-restore script, perform the following steps.

Download or cut-and-paste the script file to any location on your system. At the command line, enter Perl scriptname , where scriptname is the name of the script file. Press Enter. The system prompts you for values for each option. Alternatively, you can enter values for the options when you enter the Perl scriptname command before you press Enter. Either way, the script requires that you enter a value for each option. The script starts running, printing out the commands that it issues, which provides you with a record of the CLIs.

You can use these CLIs for a later restore, which is particularly useful if you want to restore only one or two files. Auto Update is a protocol specification that allows an Auto Update Server to download configurations and software images to many ASAs and can provide basic monitoring of the ASAs from a central location. This section describes how Auto Update is implemented and why you might want to use Auto Update.

The ASA can be configured as either a client or a server. As an Auto Update client, it periodically polls the Auto Update Server for updates to software images and configuration files. Auto Update is useful in solving many issues facing administrators for ASA management, such as:. Overcoming dynamic addressing and NAT challenges.

Committing configuration changes in one action. Providing a reliable method for updating software. Leveraging well-understood methods for high availability failover. Simplifying security solutions for Service Provider environments. The Auto Update specification provides the infrastructure necessary for remote management applications to download ASA configurations, software images, and to perform basic monitoring from a centralized location or multiple locations.

The Auto Update specification allows the Auto Update server to either push configuration information and send requests for information to the ASA, or to pull configuration information by having the ASA periodically poll the Auto Update server. The Auto Update server can also send a command to the ASA to send an immediate polling request at any time.

The following restrictions and behaviors apply to Auto Update Server support in failover configurations:. When loading a new platform software image, the failover pair stops passing traffic. When using LAN-based failover, new configurations must not change the failover link configuration. If they do, communication between the units will fail. Only the primary unit will perform the call home to the Auto Update Server. The primary unit must be in the active state to call home.

If it is not, the ASA automatically fails over to the primary unit. Only the primary unit downloads the software image or configuration file. The software image or configuration is then copied to the secondary unit. The following is an overview of the Auto Update process in failover configurations.

This process assumes that failover is enabled and operational. The Auto Update process cannot occur if the units are synchronizing configurations, if the standby unit is in the failed state for any reason other than SSM card failure, or if the failover link is down.

Both units exchange the platform and ASDM software checksum and version information. The primary unit contacts the Auto Update Server. If the primary unit is not in the active state, the ASA first fails over to the primary unit and then contacts the Auto Update Server. If the primary unit determines that the platform image file needs to be updated for either the active or standby unit, the following occurs:. The primary unit copies the image to the standby unit and then updates the image on itself.

If both units have new image, the secondary standby unit is reloaded first. If hitless upgrade can be performed when secondary unit boots, then the secondary unit becomes the active unit and the primary unit reloads. The primary unit becomes the active unit when it has finished loading. If hitless upgrade cannot be performed when the standby unit boots, then both units reload at the same time.

If only the secondary standby unit has new image, then only the secondary unit reloads. The primary unit waits until the secondary unit finishes reloading. If only the primary active unit has new image, the secondary unit becomes the active unit, and the primary unit reloads.

The primary unit copies the ASDM image to the standby unit, if needed. The primary unit updates the ASDM image on itself. If the primary unit determines that the configuration needs to be updated, the following occurs:. The primary unit retrieves the configuration file from the using the specified URL.

The new configuration replaces the old configuration on both units simultaneously. If the checksums match for all image and configuration files, no updates are required. The process ends until the next poll time. A new window appears that asks you to verify the details of the reload.

Select Save the running configuration at the time of reload and then choose a time to reload. You can also specify whether or not the device should force a reload immediately if a scheduled reload fails. Check On Reload failure, force an immediate reload after and then specify a maximum hold time. This is the amount of time that the security appliance waits to notify other subsystems before a shutdown or reboot.

Click Schedule Reload. Once the reload is in progress, a Reload Status window appears that indicates that a reload is being performed. An option to exit ASDM is also provided. Select ASDM as the image type to upload from the drop-down menu. Click OK once the image is updated with the new image. When the username and password prompt appears, provide the Cisco.

The Cisco. In te Overview section, click Next. In the Select Software section, check the software which needs to be upgraded. Click Next once the appropriate versions are selected. The Installation of the images start and the overall progress can be seen as below. Once completed click Finish. In the Results section, check the "Save configuration and reload device now" option.

Click Finish. The Reload status screen appears while the device reloads. The copy tftp flash command enables you to download a software image into the Flash memory of the firewall via TFTP. You can use the copy tftp flash command with any security appliance model.

The image you download can now be used upon the next reboot , by changing the boot system variable to point to this image. Note: For ASA, keyword disk0 replaces flash in the copy command. If you only enter a colon, parameters are taken from the tftp-server command settings. If other optional parameters are supplied, then these values are used in place of the corresponding tftp-server command setting.

If any of the optional parameters, such as a colon and anything after it are supplied, the command runs without a prompt for user input. The location is either an IP address or a name that resolves to an IP address via the security appliance naming resolution mechanism, which is currently static mappings via the name and names commands.

The security appliance must know how to reach this location via its routing table information. This depends on your configuration. The pathname can include any directory names besides the actual last component of the path to the file on the server. The pathname cannot contain spaces. If a directory name has spaces set to the directory in the TFTP server instead of in the copy tftp flash command, and if your TFTP server is configured to point to a directory on the system from which you download the image, you only need to use the IP address of the system and the image filename.

The TFTP server receives the command and determines the actual file location from its root directory information. The server then downloads the TFTP image to the security appliance. These commands are needed to upgrade the software image as well as the ASDM image and make it as a boot image at the next reload.

This command allows you to specify parameters, such as remote IP address and source file name. This procedure is similar to TFTP. In TFTP mode, options specified with the tftp-server command can be pulled and executed. But with FTP, there is no such option.

Splashtop streamer second display ipad When you upgrade the ASAv, you specify a different image in flash memory. Optional If the Auto Update Server has not been contacted for a certain period of time, entering the following command causes it to stop passing traffic:. If you do not provide a location, the following default names are used:. See also known downgrade issues in Guidelines and Limitations for Downgrading. We recommend manually disabling cluster on the control unit if possible so that a new control unit can be elected as quickly and cleanly as possible.

Check the Enable secure copy server check box. You can manually add or delete servers and their keys from the ASA database if desired. For a new server, in the Host field, enter the server IP address. Check the Add public key for the trusted SSH host check box. Fingerprint—Enter the already hashed key; for example, a key that you copied from show command output.

Key—Enter the public key or hashed value of the SSH host. The key string is the Base64 encoded RSA public key of the remote peer. You can obtain the public key value from an open SSH client; that is, from the. After you submit the Base64 encoded public key, that key is then hashed via SHA Optional To be informed when a new host key is detected, check the Inform me when a new host key is detected check box. By default, this option is enabled.

When this option is enabled, you are prompted to accept or reject the host key if it is not already stored on the ASA. When this option is disabled, the ASA accepts the host key automatically if it was not stored before. From a client on the external host, perform an SCP file transfer. For example, in Linux enter the following command:. The -v is for verbose, and if -pw is not specified, you will be prompted for a password.

In this way, you can back up and propagate configuration files to multiple ASAs. This section lets you predefine the path to a TFTP server so you do not need to enter it in commands such as copy and configure net. Check the Enable mount point check box. In the User Name field, enter the name of the user authorized for file system mounting on the server.

In the Password field, enter the password for the user authorized for file system mounting on the server. In the Confirm Password field, reenter the password. Click OK. Check the Enable check box. When you choose Passive mode, the client initiates both the FTP control connection and the data connection.

The server responds with the number of its listening port for this connection. To use the file management tools, perform the following steps. The Folders pane displays the available folders on disk. Flash Space shows the total amount of flash memory and how much memory is available. The Files area displays the following information about files in the selected folder:. Click View to display the selected file in your browser.

Click Cut to cut the selected file for pasting to another directory. Click Copy to copy the selected file for pasting to another directory. Click Paste to paste the copied file to the selected destination. Click Delete to remove the selected file from flash memory.

Click Rename to rename a file. Click New Directory to create a new directory for storing files. Click File Transfer to open the File Transfer dialog box. See Transfer Files for more information. See Add Mount Points for more information. The File Transfer tool lets you transfer files from either a local or remote location. You can transfer a local file on your computer or a flash file system to and from the ASA. To transfer files between your local computer and a flash file system, perform the following steps.

Select and drag the file s from either your local computer or the flash file system that you want to upload or download to the desired location. Alternatively, select the file s from either your local computer or the flash file system that you want to upload or download, and click the right arrow or left arrow to transfer the file s to the desired location. Click Close when you are done. To transfer files between a remote server and a flash file system, perform the following steps.

To transfer a file from a remote server, click the Remote server option. Optional Specify the interface through which the ASA communicates with the server. If you do not specify the interface, the ASA checks the management-only routing table; if there are no matches, it then checks the data routing table.

Choose the path to the location of the file, including the IP address of the server. File transfer supports IPv4 and IPv6 addresses. Valid FTP types are the following:. To transfer the file from the flash file system, click the Flash file system option. Enter the path to the location of the file or click Browse Flash to find the file location.

In addition, you can copy a file from your startup configuration, running configuration, or an SMB file system through the CLI. For instructions about using the copy command, see the CLI configuration guide. Define the destination of the file to be transferred. To transfer the file to the flash file system, choose the Flash file system option. To transfer a file to a remote server, choose the Remote server option. Enter the path to the location of the file.

For FTP transfers, enter the type. Valid types are the following:. Click Transfer to start the file transfer. The Enter Username and Password dialog box appears. Enter the username, password, and domain if required for the remote server. Click OK to continue the file transfer. The file transfer process might take a few minutes; make sure that you wait until it is finished. Click Close when the file transfer is finished. If you do not set the image, the default boot image is used, and that image may not be the one intended.

For the startup configuration, you can optionally specify a configuration file. Package updates are managed by ASA using this procedure. Although these platforms use the ASA to identify the image to boot, the underlying mechanism is different from legacy ASAs. See the command description below for more information. But if you manually chose a different ASDM image that you uploaded for example, asdm When you upgrade the ASAv, you specify a different image in flash memory.

Note that if you later clear your configuration, then the ASAv will revert to loading the original deployment image. You can upgrade the ASDM image separately. Firepower , and in Appliance mode—Boots the previously-running boot image. You cannot use this procedure to set the ASA image. Startup configuration—By default, the ASA boots from a startup configuration that is a hidden file.

Firepower , in Appliance mode: You can only add a single image. If you upgrade to a new image, then you must delete the previous image you set. When you apply this change, the system performs an action: the system validates and unpacks the image and copies it to the boot location an internal location on disk0 managed by FXOS.

The new image will load when you reload the ASA. If you change your mind prior to reloading, you can delete the Boot Image Location and reapply to remove the new image from the boot location, so the current image continues to run. You can even delete the original image file from the ASA flash memory after you apply this change, and the ASA will boot correctly from the boot location.

Unlike other models, this command in the startup configuration does not affect the booting image. The last-loaded boot image will always run upon reload. You can only load images with the original filename from the Cisco download site. If you change the filename, it will not load. Other models: You can specify up to four local binary image files for use as the startup image, and one image located on a TFTP server for the device to boot from.

If you specify an image located on a TFTP server, it must be first in the list. If the device cannot reach the TFTP server to load the image, it tries to load the next image file in the list located in flash. Browse to the image from which you want to boot.

Arrange the images in order by using the Move Up and Move Down buttons. Optional In the Boot Configuration File Path field, specify the startup configuration file by clicking Browse Flash and choosing the configuration. We recommend that you make regular backups of your configuration and other system files to guard against system failure. These procedures describe how to back up and restore configurations and images to a zip file and transfer it to your local computer.

You should have at least MB of disk space available at the backup or restore location before you start a backup or restore. If you make any configuration changes during or after a backup, those changes will not be included in the backup. If you change a configuration after making the backup, then perform a restore, this configuration change will be overwritten.

As a result, the ASA might behave differently. You can start only one backup or restore at a time. You can only restore a configuration to the same ASA version as when you performed the original backup. You cannot use the restore tool to migrate a configuration from one ASA version to another. If you use clustering, you can only back up or restore the startup-configuration, running-configuration, and identity certificates.

You must create and restore a backup separately for each unit. If you use failover, you must create and restore a backup separately for the active and standby units. If you set a master passphrase for the ASA, then you need that master passphrase to restore the backup configuration that you create with this procedure. If you do not know the master passphrase for the ASA, see Configure the Master Passphrase to learn how to reset it before continuing with the backup.

If you import PKCS12 data with the crypto ca trustpoint command and the trustpoint uses RSA keys, the imported key pair is assigned the same name as the trustpoint. Because of this limitation, if you specify a different name for the trustpoint and its key pair after you have restored an ASDM configuration, the startup configuration will be the same as the original configuration, but the running configuration will include a different key pair name.

This means that if you use different names for the key pair and trustpoint, you cannot restore the original configuration. To work around this issue, make sure that you use the same name for the trustpoint and its key pair. Each backup file includes the following content:. Cisco Secure Desktop and Host Scan images. Cisco Secure Desktop and Host Scan settings. AnyConnect SVC client images and profiles. AnyConnect SVC customizations and transforms.

Identity certificates includes RSA key pairs tied to identity certificates; excludes standalone keys. This procedure describes how to perform a complete system backup. Create a folder on your computer to store backup files so they will be easy to find in case you need to restore them later. The Backup Configurations dialog box appears. By default, all configuration files are checked and will be backed up if they are available.

If you want to back up all of the files in the list, go to Step 5. Uncheck the Backup All check box if you want to select the configurations to back up. Check the check box next to the option that you want to back up. Click Browse Local to specify a directory and file name for the backup. In the Select dialog box, choose the directory in which you want to store the backup file. Click Select. The path appears in the Backup File field. Enter the name of the destination backup file after the directory path.

The backup file name must be between 3 and characters long. Click Backup. The backup proceeds immediately unless you are backing up certificates or the ASA is using a master passphrase. If you have configured and enabled a master passphrase on your ASA, you receive a warning message with a suggestion to change the master passphrase, if you do not know it, before proceeding with the backup. Click Yes to proceed with the backup if you know the master passphrase. The backup proceeds immediately unless you are backing up identity certificates.

If you are backing up an identity certificate, you are asked to enter a separate passphrase to be used for encoding the certificates in PKCS12 format. You can enter a passphrase or skip this step. Only identity certificates are backed up by this process. To encrypt certificates, enter and confirm your certificate passphrase in the Certificate Passphrase dialog box and click OK. You will need to remember the password you enter in this dialog box when restoring the certificates.

Clicking Cancel skips the step and does not back up certificates. After clicking OK or Cancel, the backup begins immediately. After the backup is complete, the status window closes and the Backup Statistics dialog box appears to provide success and failure messages. Click OK to close the Backup Statistics dialog box. You can specify configurations and images to restore from a zip tar.

In the Restore Configurations dialog box, click Browse Local Directory , choose the zip file on your local computer that contains the configuration to restore, then click Select. The path and the zip filename appear in the Local File field. Click Next. The second Restore Configuration dialog box appears. Check the check boxes next to the configurations that you want to restore.

Click Restore. If you specified a certificate passphrase with which to encrypt the certificates when you created the backup file, ASDM prompts you to enter the passphrase. If you chose to restore the running configuration, you are asked if you want to merge the running configuration, replace the running configuration, or skip this part of the restoration process. Merging configurations combines the current running configuration and the backed-up running configuration.

Replacing the running configuration uses the backed-up running configuration only. Skipping the step does not restore the backed-up running configuration. ASDM displays a status dialog box until the restore operation is finished. If you replaced or merged the running configuration, close ASDM and restart it. If you did not restore the running configuration or the running configuration, refresh the ASDM session for the changes to take effect.

On the ISA , you can configure automatic backups to a particular location every time you save your configuration. Automatic restore lets you easily configure new devices with a complete configuration loaded on an SD flash memory card. Automatic restore is enabled in the default factory configuration.

Check or uncheck Automate Backup Configuration to enable or disable automatic backups. If you enable automatic backups, when you save the configuration, the configuration is automatically saved to the backup location as well as to the startup configuration.

The backup file has the name "auto-backup-asa. Interface —Specifies the interface to reach the backup URL, if you specify off-device storage. If you do not specify the interface name, the ASA checks the management-only routing table; if there are no matches, it then checks the data routing table. Location —Specifies the storage medium to be used for backing up data.

You can specify a URL or local storage. And disk3 is the SD memory card. The default for automatic restore is disk Passphrase —Sets the passphrase to secure the backed-up data. The default for automatic restore is "cisco". Automatic restore mode restores the system configuration on a device without any user intervention. For example, you insert an SD memory card containing a saved backup configuration into a new device and then power the device on.

When the device comes up, it checks the SD card to decide if the system configuration needs to be restored. The restoration is only initiated if the backup file has the "fingerprint" of a different device. The fingerprint of the backup file is updated to match the current device during a backup or restore operation. So if the device has already completed a restore, or if it has created its own backup, then the automatic restore is skipped. If the fingerprint shows a restoration is required, the device replaces the system configuration startup-config, running-config, SSL VPN configuration, and so on; see Back Up the System for details about the contents of the backup.

When the device finishes booting, it is running the saved configuration. Automatic restore is enabled in the default factory configuration, so you can easily configure new devices with a complete configuration loaded on an SD memory card without having to perform any pre-configuration of the device. Because the device needs to decide early in the boot process if the system configuration needs to be restored, it checks ROMMON variables to determine if the device is in automatic restore mode and to obtain the location of the backup configuration.

If you need to restore the default configuration to ensure that automatic restore is enabled, use the configure factory default command. This command is only available in transparent firewall mode, so if you are in routed firewall mode, use the firewall transparent command first. Check or uncheck Automate Restore Configuration to enable or disable automatic restore.

The name of the file that is restored is "auto-backup-asa. If you enable automatic restore, set the following parameters:. Location —Specifies the storage medium to be used for restoring data. The default is disk3. Passphrase —Sets the passphrase to read the backed-up data. The default is "cisco". This feature stores a copy of the current running configuration file on a TFTP server. The System Reload tool lets you schedule a system restart or cancel a pending restart.

In the Reload Scheduling area, define the following settings:. For the Configuration State, choose either to save or discard the running configuration at restart time. For the Reload Start Time, choose from the following options:. Click Now to perform an immediate restart. Click Delay by to delay the restart by a specified amount of time. Enter the time before the restart begins in hours and minutes or only minutes. Click Schedule at to schedule the restart to occur at a specific time and date.

Enter the time of day the restart is to occur, and select the date of the scheduled restart. Check the On reload failure force immediate reload after check box to show the amount of time elapsed in hours and minutes or only minutes before a restart is attempted again. Click Schedule Reload to schedule the restart as configured. The Reload Status area displays the status of the restart. Click Cancel Reload to stop a scheduled restart.

Click Refresh to refresh the Reload Status display after a scheduled restart is finished. Click Details to display the results of a scheduled restart. Auto Update is a protocol specification that allows an Auto Update Server to download configurations and software images to many ASAs and can provide basic monitoring of the ASAs from a central location. This section describes how Auto Update is implemented and why you might want to use Auto Update. The ASA can be configured as either a client or a server.

As an Auto Update client, it periodically polls the Auto Update Server for updates to software images and configuration files. Auto Update is useful in solving many issues facing administrators for ASA management, such as:. Overcoming dynamic addressing and NAT challenges. Committing configuration changes in one action. Providing a reliable method for updating software. Leveraging well-understood methods for high availability failover.

Simplifying security solutions for Service Provider environments. The Auto Update specification provides the infrastructure necessary for remote management applications to download ASA configurations, software images, and to perform basic monitoring from a centralized location or multiple locations. The Auto Update specification allows the Auto Update server to either push configuration information and send requests for information to the ASA, or to pull configuration information by having the ASA periodically poll the Auto Update server.

The Auto Update server can also send a command to the ASA to send an immediate polling request at any time. The following restrictions and behaviors apply to Auto Update Server support in failover configurations:. When loading a new platform software image, the failover pair stops passing traffic. When using LAN-based failover, new configurations must not change the failover link configuration. If they do, communication between the units will fail.

Only the primary unit will perform the call home to the Auto Update Server. The primary unit must be in the active state to call home. If it is not, the ASA automatically fails over to the primary unit. Only the primary unit downloads the software image or configuration file. The software image or configuration is then copied to the secondary unit. The following is an overview of the Auto Update process in failover configurations. This process assumes that failover is enabled and operational.

The Auto Update process cannot occur if the units are synchronizing configurations, if the standby unit is in the failed state for any reason other than SSM card failure, or if the failover link is down. Both units exchange the platform and ASDM software checksum and version information. The primary unit contacts the Auto Update Server. If the primary unit is not in the active state, the ASA first fails over to the primary unit and then contacts the Auto Update Server. If the primary unit determines that the platform image file needs to be updated for either the active or standby unit, the following occurs:.

The primary unit copies the image to the standby unit and then updates the image on itself. If both units have new image, the secondary standby unit is reloaded first. If hitless upgrade can be performed when secondary unit boots, then the secondary unit becomes the active unit and the primary unit reloads. The primary unit becomes the active unit when it has finished loading. If hitless upgrade cannot be performed when the standby unit boots, then both units reload at the same time.

If only the secondary standby unit has new image, then only the secondary unit reloads. The primary unit waits until the secondary unit finishes reloading. It delivers enterprise-class firewall capabilities for ASA devices in an array of form factors - standalone appliances , blades , and virtual appliances - for any distributed network environment.

ASA Software also integrates with other critical security technologies to deliver comprehensive solutions that meet continuously evolving security needs.
