Nexus 2248 to Nexus 7010

kedwards · ‎09-01-2011

I'm not sure this relationship is as easy as it sounds. I have a 2248TP connecting on uplinks 3&4 to two ports (25&26) of a Nexus 2010 N7K-M132XP-12 card. I have followed the steps on CCO (install feature-set, activate feature-set, port-channel and interface config.) to the letter. I have also made sure that my transceiver is supported, when in fact, the transceiver used to be plugged into an N5K and worked beautifully. But I still get the error: "Configuration does not match the port capability" when I try to do the command "switchport mode fex-fabric" on the individual ports. But what's worse, It has gotten the fex serial number and type, but refuses to bring it on-line.

Can you post the port config (25 and 26) and the port-channel?

Hm... Interesting, can you post the output of the following:

Okay, I see the problem.

Chassis1(config)# sh int e 2/25 cap
Ethernet2/25
Model:                 N7K-M132XP-12
Type (SFP capable):    10Gbase-(unknown)
......
FEX Fabric:            no
dot1Q-tunnel mode:     yes

FEX Fabric under the port capabilities said it is not supported. And according from the EPLD version, you are not running the minimum EPLD version to support FEX:

Please see the following link on how to install EPLD. Also, installing EPLD is discrupted because it will reload a LC:
