File Management

In addition to letting you back up and restore configuration files, and deploy firmware updates to devices, this menu manages viewing and comparing configuration files backed up from the selected devices. Details about these capabilities appear below.

Compare and View options have the following limitations:

• If you select a config file that is a single file, without any historical precedent, no comparison option appears on the menu since the selected version does not have a prior version.

• If you select a single config file of version two or higher, comparison is an option. When selected, Open Manage Network Manager automatically compares against the prior version for that device and file name.

• If you select two config files of any version, compares is between those two versions.

• If you select three or more config files, no comparison option appears.

• The View option appears for a single selection only, and only lets you view files that are not binary.

The icon to the left of the File Name listed in the portlet lets you know whether a configuration file is binary (), and not viewable, or text (), and viewable.

The file management menu contains the following:

This opens a panel displaying the configuration file’s contents. Use the browser’s Find function to locate specific text within the Config File. You can also select and copy text within this screen.

Notice that Selected Config and Live Config (current) version and storage dates appear at the top of this screen. When you perform a backup that differs from the config that is Labeled Current, that label changes to Live Config if changes are detected.

Selected Config appears when you open this screen from the Configuration Files Portlet, but Live Config / Current Config appear side-by-side when you open this screen from the Managed Resources portlet.

You can also compare two different configurations (Selected Config and Labeled Current / Live Config) in the tabs that appear on this screen. with the Compare Files tab at the top.

Close the screen with the buttons at its bottom. Notice you can also Backup or Restore what you are viewing with buttons at the bottom of the screen.

Assign Labels-- Use this option to select an existing label or create a new one. You cannot assign System labels (Current, Compliant, and so on).

Compare Current v. Previous / to Label   / Selected-- You can compare configurations by right-clicking a device, or two devices then selecting Compare. If you right click a single device with a previous backup, then the comparison is between the latest and next-to-latest backup. If it does not have a previous backup, then the menu offers to compare to a designated label. You can compare two different Selected devices too.

Ctrl+click to select two different devices before you Compare.

Notice that the Prev / Next buttons at the bottom of this screen cycle through as many as five previous configuration files.

The comparison screen appears with the configurations side-by-side (note the file names in the title bar of this screen).

Colors: Lines that differ between the two configurations appear highlighted green. Lines missing in one, but that appear in another appear highlighted red. Added lines are yellow.

Use the right/left arrows to page through the side-by-side comparison. The page numbers and beginning / forward / back / end arrows help you navigate between pages of pairs of files. Notice also that if you have more than two such files, a panel appears at the bottom that lets you navigate between adjacent pairs of such files (1 and 2, 2 and 3, 3 and 4, and so on). Click the Prev / Next links to move between pairs of files.

Use the browser’s “Find” function (typically initiated by Ctrl+F) to locate text within these views.

Backup / Restore -- Select these to backup or restore a configuration file. See How to: Backup Configurations or Restore Configurations for step-by-step instructions.

Deploy -- Select this option to deploy an OS Image (firmware). See Deploy Firmware for more.

Some devices, including the Dell Force10 C-Series and E-Series, first permit then drop telnet connections during deployment or file restoration when you select restart as part of the process. This can take from six to eight minutes, though it can take as long as fifteen minutes for a fully populated chassis. During that time, ping detects the device; however, Open Manage Network Manager cannot log in to the device until the reboot is complete.

Restoring configurations to Dell Force 10 devices may produce errors when individual commands already exist in the running config and cannot be overwritten. Open Manage Network Manager ignores such errors and reports success by default since the errors indicate a command was not applied, not that restoration was unsuccessful. Best practice is to restore to startup config to avoid these errors, especially when scheduling backup or backing up a group on such devices.

Export / Import  -- Export lets you save a local copy of the selected config file. Import opens a screen that lets you select a locally-accessible file to store, view, compare and deploy.

View configuration files in the History > Latest Configurations portion of the Equipment Details screen for a device or in the Configuration Files or Top Configuration Backups portlets.

Backup Configurations

Open Manage Network Manager simplifies backing up devices so you always have their configuration files, even if the one on the device becomes corrupted or out-of-date.

You can back up several devices at once for what amounts to a “group operation.” Select more than one device by Ctrl+clicking in the expanded portlet, then right-click as outlined below. You must expand portlets to multi-select.

Here are the steps to back up a device:

1. Make sure you have configured an FTP or TFTP server to handle the backup. See Netrestore File Servers.

2. Right-click a device in the Managed Resources portlet.

3. Select File Management > Backup.

4. Configure the subsequent Backup Device screen.

This screen lets you configure the following:

File Name -- A text identifier for the file

Description -- A text identifier for the file

Update User Label -- A text identifier for the file. Entering such a label creates it, and makes it available for later restoration, comparison, and so on.

Email Settings -- Click add email to configure an email notification about this backup.

Select Targets for Backup -- This screen defaults to the device you selected in Managed Resources. You can also click the Add Equipment to add individual devices, or Add Groups to add groups, or Remove All to manage devices that appear in this list of targets.

Device Options -- This portion of the Backup Options screen displays detailed configuration options available for the selected target. For example, you could select between backing up the running-config and the startup-config.

5. Click one of the buttons at the bottom of the screen to initiate the next backup action.

Add Schedule opens the scheduling screen to let you automate the backup you have configured on a specified date, time, or repetition.

Execute performs the backup immediately. The Results tab in this screen opens, displaying the message traffic between Open Manage Network Manager and the device(s). See Audit Trail Portlet.

Save preserves this configuration without scheduling or executing it.

Close closes this screen without saving the configured restoration.

Restore Configurations

The following are the steps to restore a config file to a device:

1. Make sure you have configured an FTP or TFTP server to handle the backup. See Netrestore File Servers.

2. Right-click a device in the Managed Resources portlet.

3. Select File Management > Restore.

4. Configure the subsequent Restore Device screen.

This screen’s tabs lets you configure the following:

Select Targets for Restore -- This portion of the screen lets you Add Equipment, Add Groups, or Remove All target devices. Listed targets and their Restore Config / Label Selection. Click the icon in the Action column to remove the listed target.

Select what to apply to the selected targets above  -- This panel lets you select either a label (like Current, Compliant and so on--a selector listing available labels appears onscreen once you click this option), or Restore a specific Configuration File. The latter lists available files and lets you click to select. Click Apply to configure the selected target, or Apply to All to configure all targets.

Select Device Options based on selected targets -- The Driver Options tab lets you select device-specific restoration options.

5. Click one of the buttons at the bottom of the screen to initiate the next backup action.

Add Schedule opens the scheduling screen to let you automate the restoration you have configured on a specified date, time, or repetition.
