    Display the Redundant Routing Engines Installed in the Router

    Purpose

    To check for redundant Routing Engines in the router.

    Action

    To determine whether a router has redundant Routing Engines, use the following command:

    user@host> show chassis hardware

    Note: If the show chassis hardware command displays no hardware information, check to see which Routing Engine you are logged in to. If you are logged in to the backup Routing Engine, no hardware information is displayed or there are errors.

    Sample Output

    user@host> show chassis hardware
    Hardware inventory:
