Hello engineers,I have a need to migrate some DC access switches (mostly 93180 nexus) that are currently connected to a pair of Nexus7K to a new pair of NX9364 (NXOS image). My question here is to know if it is possible to do so without causing servi...
Hello, I am designing a new DC and considering using double-sided vPC between Spine (N9K-C9364C-GX) switches and Leaf (N9K-C93180YC-FX3) switches. I reviewed the Cisco vPC best practices but wasn't able to find how many vPC domains are supported in t...
It's been a while since i had to deal with STP But can someone refresh my memory? Given the topology where i would have two nx9ks setup as a vpc domain feeding single switches (That will never cross connect to another set of switches), So it would be...
