LACP between a R1-2210 VRTX 10Gb Switch & Cisco 3650 Stack will not bundle properly. Has anybody seen this/have any ideas? Running what is currently the latest firmware on the VRTX Switch and CAT3K_CAA-UNIVERSALK9-M on the Stack. As a side note- we do have LACP bundles between Dell 630s that are working fine.

Configs:

R1-2210 VRTX 10Gb Switch:

Configurations are identical on our functioning Port Channels to our Dell 630s.

I appreciate any insight from the community.

Thanks for your time!
