Is it possible to have in a stack Catalyst 3750 with EMI version and Catalyst 3750 with SMI?. In my case, it is a WS-C3750G-12S-E with WS-C3750-48PS-S. I didn't find clear information about this issue. I know different major releases are not compatible but nothing is mentioned about the feature set.
Re: Stacking 3750 switches with EMI and SMI versions
It's possible but not recommended. If you decide to do this you should buy 2 EMI so that if the master fails the backup can still route traffic. (Having 2 EMI is TAC supported, even if the rest is SMI - not sure about just having one EMI and one SMI)
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
