Use the Cisco IOS XR Web UI

Select the Cisco IOS XR router and open its Web UI from the device toolbar.

Check the router name and review the available management pages.

In Interfaces, choose the connected port, enter a description, and select Apply.

Open the router terminal and verify the description in its running configuration.

Use the Routing page to inspect the configured static route and its next hop.

Check the same destination in the live routing table from the terminal.

Reopen the lab and check that the same port still shows its saved description.
