Question about IOS upgrades on 3750 stacked switches

Answered Question
Jun 7th, 2007


I am going to be performing upgrades on all my switches.

I'm running RME 4.0.5 and I had been having difficulty with creating stacks using the 'Cisco Cluster Management Suite' device type.

I managed to get archives by just adding the stack master as a regular switch - the archives pulled in all the switch info on the other switches in the stack as well (ie. FastEthernet3/1 for the third switch in the stack), so that was good enough for me.

Now, since the stacks are added into my RME in this way, how would pushing a software upgrade via Software Distribution work? If I push an upgrade to the master switch, will it propagate to the other switches in the stack as well?

Any thoughts on this would be appreciated.



I have this problem too.

The SWIM upgrade will handle all stack members as well. The switch CLI will actually handle putting the same image on all member flash file systems. See for how this upgrade works under the covers.
