Hi, We have a dual-homed topology in where I have 2 pair of N5k and its configured with vPC. N2k/Fex is currently dual-connect on both primary and secondary N5k(parent). What would be the output on the ff. scenario.
Scenario 1: I have upgrade the primary N5k?
- Please confirm if the vPC peer link connection/status on both parent still be in "peer adjacency formed" or down?
- Please confirm if the vPC on the downstream(fex) will in down state due to version mismatch?
- If I have upgrade the primary switch to a newer version and fex still running the old version will it still be synchronize/be online to the primary switch with newer version? or the fex's will only be transferred/online on the secondary switch? So if this true all the traffic will be forwarded to Secondary N5k (old version) from Fex.
Thank you
