Hello all, I'm attempting to create an FC port-channel from my 6120XP to an MDS 9148. I have NPIV as well as F-Port-Channel-Trunking features enabled. Right now I'm just trying to get the port-channel itself working and not worrying about the trunking aspect just yet (uplink trunking is turned off on the FI). The MDS is running 5.0(1a) and the FIs are on 2.1t. I have confirmed that single uplinks do come up, but whenever I try to bind them into a port-channel, the links themselves go into an "error disabled" state. I've gone over previous articles and docs on here and haven't been able to shed any light on why this isn't working. Any assistance would be greatly appreciated. Uplink error and MDS configs below. Thanks!

Hello,
Does VSAN configuration on both ends match ?
On UCS FI
connect nxos
show int san-port-channel X
MDS
show int port-channel X

Hi Padma, thanks for the response. It appears so, I'm using the default VSAN (1) for both ends, which seems to work for single links. Here's the output from both ends:

Would you provide the output of the interface configs
show run interf fc 1/13-14
show run interf san-port-channel 4
Thanks

Sure, thanks Dave:

Sorry, one more thing, The output of show vsan memebership from UCS and MDS, you can trim to just the fc and san-port-channels if you want.
Being in non-trunk mode, VSAN membership of all interfaces fc and port-channel must match

Not a problem:

fc1/13

allowed list:1-4078,4080-4093
fc1/14

FI:

Well I guess there's an issue with the 9148. We have a 9124 that had a single free port so I configured the PC on it maching what the 9148 had and it came up immediatley. Both MDSs are on the same NX-OS version 5.0(1a). Any config ideas (I'm comparing the configs now) or maybe a bug?

Thanks, I've been meaning to update, but the issue still isn't resolved. We're hitting bug: CSCtq08625
The switch also has a field notice for incorrect MAC programming. The new OUIs were included in FM 5.0(4d) and later I believe (we're running 5.0(4d) and no problems with it). Right now TAC is escalating to development.......
