Quick, easy question.

What's the command to switch between the active and standby supervisor cards on a 4500 series switch?

Hi

The "redundancy force-switchover" command conducts a manual switchover to the redundant supervisor engine. The redundant supervisor engine becomes the new active supervisor engine running the Cisco IOS image. The modules are reset.

Hope this helps

Re: Quick, easy question.

What happens when I issue that command but the redundant supervisor is in "Cold" mode? I'm looking for the shortest downtime when upgrading code on a 65xx switch with dual sup720's? I loaded the new code on the slavedisk0:, and do a "hw-module mod x reset" to make sure the redundant sup720 boots OK, and it comes up in Cold Mode.

Should I then do a "redundancy force-switchover" or a "warm boot disk0:*.bin" to get the primary supervisor on the same code with the least amount of downtime?
