Procedure

1.     From the navigation pane, select Device > Virtualization > IRF.

2.     Click the  icon next to Advanced settings.

3.     Change the IRF domain ID on the following page:

 

 

Changing the IRF bridge MAC persistent time

Consequences

This operation might affect traffic forwarding on an IRF fabric.

Procedure

1.     From the navigation pane, select Device > Virtualization > IRF.

2.     Click the  icon next to Advanced settings.

3.     Change the IRF bridge MAC persistence setting on the following page:

 

 

License management

Uninstall a license

Consequences

Uninstalling a license makes the licensed feature inaccessible.

Procedure

1.     From the navigation pane, select Device > License Management > License Management.

2.     Uninstall a license on the following page:

 

 

Compressing the license storage

Consequences

The compression operation clears expired licenses and uninstalled licenses.

If uninstalled licenses or expired licenses exist on the device, the compression operation will make the DID change. Before performing a compression, make sure all licenses registered with the old DID have been installed and all Uninstall keys of the uninstalled licenses have been backed up. You will be unable to install such licenses or restore such Uninstall keys after the compression.

Procedure

1.     From the navigation pane, select Device > License Management > License Management.
