I need to peer-link two switches. Can I peer-link a Cisco 3750G running 12.2.55-SE12 with a Cisco 3850 Running Denali-16.3.7? It would be a temporary solution for us, I know the 3750G's are end of support. We're just looking for a temporary fix. My concern is with that the IOS for the G's wont be compatible with Denali on the 3850. Thanks for any help.
So you want to connect them using etherchannel spread across both switches in each stack ?
If so I cannot see why this wouldn't work but can't say for sure as I have not done it between those specific switch stacks.
