ISC Between Two Stacks of Different Switch Models

I’ve looked around for information on this topic, but haven’t found anything definitive yet; I was wondering if it was possible to link two stacks of switches, that are different models of switch, together via ISC for MLAG. Specifically, I have a stack of X460-G2-48p-10GE4s and a stack of X450-G2-48p-10GE4s. Both stacks are V-Stacks using the ‘alternate ports’ (51/52). To connect the “Slots” of the stack together, X460-slot1 port 49 would connect to X450-slot1 port 49, and similarly on X460-slot2 port 49 connecting to X450-slot2 port 49.


Is this something that should even be tried, has someone had to do this? For what it’s worth, this would only be temporarily for a few months and eventually the X450s in the design would be upgraded to X460s.


Thanks for any information

I didn’t play like that but I think it’s ok to try. What I remember a standalone/stack/modular EXOS should be peered with standalone/stack/modular, not mixed. But didn’t see model restrictions. It is recommended however - mind the MAC table capacities for example.


Hope that helps,
