Nexus 7000 and 2000 FEX OffLine Issue

[gercedeno]

Hello Team,

Could you please provide some assistance on this issue? I have a Nexus 7000 connected a 2000 FEX. I have provisioned it based on the configuration guide, but the FEX module will not come on line. I think the problem is with software compatibility, but any help is greatly appreciated. Please see below for the output of the FEX module.

[Ruhann Du Plessis]

Have you dual connected the FEX to two upstream N7K switches and perhaps looking only at the one?

If so you would need to configure a VPC.

[Prashanth Krishnappa]

What kind of module do you have in slot 3?
