    Setup for Configuration Backup & Restore

    After successfully scheduling a live network collection to collect at minimum the Equipment CLI information, check that the task completes successfully. The Equipment CLI information is needed in order to populate the information about the OS versions on each router, based on which the commands for configuration restoration may vary.

    Next, select Configuration > Config/OS Manager... from either offline, live network, or provisioning mode. Under the Config Management folder, select Backup & Restore. The Config/OS Management window should be populated with the routers that were collected during the live network collection.

    Figure 104: Config Backup and Restore

    Config Backup and Restore

    Note that the default transfer method is populated based on the hardware type. For example, the default for Juniper is secure copy (scp), the default for Cisco is ftp, and the default for Riverstone is tftp. Please verify that the IP/MPLSView server can support the given method. If ftp has been disabled, you may be able to enable it using the command “/usr/sbin/svcadm enable ftp”. The tftp server needs to be installed on the server before using tftp in the configuration management module (see the prerequisites section for more information.)


    Global Settings


    Click “Options...” if it is necessary to modify any of the Config/OS Management settings such as the timeout, number of concurrent jobs, Username, and Password.

    • The Server IP should only be changed if there are more than one IP addresses on the IP/MPLSView server and the routers cannot access the default IP address.
    • The Server Archive Directory is the location where the configuration files will be archived to. Make sure that the user that installed IP/MPLSView as well as the current user have write permission to this directory.
    • The Server Username and Server Password fields indicate the login information that the routers will use to access the IP/MPLSView server. Note that in the case of Cisco ftp, this information may not be securely transmitted on the network, and may be visible on the router configuration file during the transfer. You may want to set up a separate user account for configuration management instead of the main IP/MPLSView user account for security reasons. However, check that the main IP/MPLSView user will still be able to access files created by this user.
    • If any routers require collection using tftp, enter in the Server TFTP Directory. This is the directory specified in the tftp initialization file used to start up the tftp server, where the files will be transferred to before saving them to the Server Archive Directory.

    Per-Router Settings


    To modify the settings for an individual router, double-click on the router. To modify the settings for selected routers, use <Ctrl>-click or <Shift>-click to select multiple routers and then click Modify. In this window, you can modify the Transfer Method and the Backup Template.

    • Transfer Method: cli, ftp, scp, or tftp. Note that different hardware types support different transfer methods, so not all of the options may be available for certain hardware types.
    • Backup Template, Restore Template: The templates with the commands used for backup and restore can be modified as necessary from Admin > Template Design under Config Management Templates (or under /u/wandl/data/templates/configmgmt). After creating a new template underneath the appropriate category, select Action > Refresh from the Templates Design window to update the index file so that it can be properly picked up, or update the index file manually in /u/wandl/data/tempaltes/configmgmt/.templates.idx. Then reopen the modify window.

    • Select “Selected for Scheduled Backup” to mark a router that should be backed up when clicking the “Schedule Backup” button.
    • Select Date to Restore, Directory to Restore, or File to Restore to restore the configuration file to the contents on a particular date, the contents in a particular directory (following the same file naming conventions as the Config Management System), or to a particular configuration file.

    Configuration Backup

    Once the global and per-router settings are configured properly, select the routers to back up and click Backup. A dialog window will open up with the following options.

    Figure 107: Backup Options

    Backup Options

    The configuration files will be saved to the Server Archive Directory underneath a date directory, for example, <Server Archive Directory>/<Datedirectory>. Alternatively, you can specify a Subdirectory in which case, the configuration files will be saved to <Server Archive Directory>/<Subdirectory>/<Datedirectory>. This subdirectory is useful to provide a meaningful label/description of the contents of the directory. For example, you could have a subdirectory “StableVersionOctober2008” to indicate that this is a set of configuration files you may want to revert to if necessary.

    A progress dialog will appear indicating the status for each router being backed up.

    Figure 108: Backup Progress

    Backup Progress

    After backing up the routers, the status will appear to indicate whether the backup was successful or not.

    Configuration Restore

    Configuration restoration is possible for JUNOS and for CiscoIOS (versions 12.3 or later). Note that for earlier versions of CiscoIOS, configuration replacement is possible for the startup configuration, but only merge is supported for the the running configuration. In this case, a separate reboot is necessary before the restoration is complete.

    To restore the configuration files to the router of a previous collection, first select one or more routers that you wish to restore and click Modify. Indicate which configuration version that you would like to restore. Note that the Subdirectory, if specified earlier, is indicated in parentheses.

    Figure 109: Config Management Settings

    Config Management Settings

    After setting the date you wish to restore, it will be populated in the Date/File to Restore column of the Config/OS Management window. You can either select the date from Date to Restore, browse for the specific date directory for Directory to Restore, or select a particular configuration file to restore on the router for File to Restore. Click OK.

    After having set the date to restore, select the routers from the Config/OS Managemetn window to be restored and click “Restore”

    At the prompt, optionally enter in comments about the restore.

    Upon clicking OK, a status window will appear indicating the status of the restoration.

    Figure 110: Restore Progress

    Restore Progress

    Following a successful restoration, you will be asked whether or not to recollect the configuration files and update the network. Click Yes to open the Live Update options, to submit a task to the Task Manager.

    Schedule Backup

    Before performing a scheduled backup, it is recommended to first test backing up the routers manually to make sure that any connectivity problems are resolved.

    1. For scheduled backup of routers, select the routers to be backed up and click the Modify button.
    2. Then select True under “Selected for Scheduled Backup.”
    3. Click the Schedule Backup... button to open the following window.

    4. Enter in the purge options to delete backups older than a particular number of days.
    5. Optionally enter in a notification e-mail. (This requires SMTP server setup on the server machine.)
    6. Click Next to enter in scheduling parameters to specify the collection interval.
    7. Click Finish.
    8. The task can be modified by clicking the Schedule Backup... button.
    9. The task status can be viewed from Admin > Task Manager.
