Check How Long Router Components Have Been Up

Purpose

When a problem occurs and you check the system to see how long it has been up, you may find that the show system uptime command displays the current time and information about how long the router, router software, and routing protocols have been running, but does not tell you if a component failed. Determining whether a component failed when a problem occurred with the router is an important step in the diagnosis of a problem.

Action

To check how long router components have been up, issue the show chassis command for the components on your router:

user@host> show chassis fpc detail

user@host> show chassis routing-engine

user@host> show chassis feb

user@host> show chassis scb

user@host> show chassis sfm

user@host> show chassis ssb

Sample Output

The following sample output is for an M20 router:

What It Means

The sample output shows the time when the component started running and how long the component has been running. A short uptime can indicate a problem with the component.
