Displaying the Redundant Routing Engines Installed in the Router

Action

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

user@host> show chassis hardware

   
NOTE: If the show chassis hardware CLI 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.
