What is the 'proper' configuration for MDS interfaces facing the UCS? The INE guide instructs us on how to enable VSAN trunking on an FI, which results in the following config change:
UCS-Lab-A(nxos)# sh run int fc1/31
switchport mode NP
switchport trunk mode on
On the upstream MDS, the default F-port configuration has trunking enabled (so it won't appear after configuration), so these seem to be a good match for each other:
MDS-1(config-if)# switchport trunk mode on
MDS-1(config-if)# sh run int fc1/4
switchport mode F
switchport description FI-A fc1/31
(trunking enabled implicitly)
So here are my questions:
1. What if I don't enable trunking on the FI? I labbed this and all seems to work.
2. Is trunking even occuring on this link? The 'show interface' command only shows F and NP modes, never TF or TNP modes.
3. Is there a place in UCSM to enable other VSANs on an interface? It only allows me to select one vsan per uplink, so I'm not sure whether a TNP configuration is even supported.
