uptime for a cisco router

Unanswered Question
Oct 9th, 2006

Is there a command like "sh uptime" in the IOS that would show how long the router has been up?


I have this problem too.

The command to check the uptime is show version. The uptime can be found in the middle part of the output and it will look something like the below output. Moreover, if the router has an authoritative clock set, either via NTP or manual 'clock set' command, it will display the date/time when it was rebooted.

R2 uptime is 1 week, 2 hours, 12 minutes

System returned to ROM by reload

System restarted at 15:44:41 UTC Mon Oct 2 2006

System image file is "flash:c3640-js-mz.124-7.bin"

use the 'show version' command and view the output for the "uptime".

a quick one more:

sh ver | s uptime ! if you have a relatively recent ios "s" will work otherwise use "inc" after pipe
