It is online. Could this "system default switchport shutdown" command be disabling the FEX ports to access VLANs ?

So, Po110 is up and the associated interfaces (e2/5 and e2/6) are up and up (sh port-ch summ)?

Is the fex connected to only one switch or both?

I do not see the vpc config in your output you posted

What is the output of "sh vpc"?

Po110 - Interface is  Down. The other interfaces are up. I have one Nexus 5K connected to one Nexus 2k hence no vpc configs.

Ok, if you don't have vpc than there is no need for the vpc config under the Portchannel. Can you remove it and test again?

Aslo, can you sh and no sh tpo110 after removing vpc command and check with sh port-ch summ?

Hello Reza,

Thanks for the replies. But if you can follow my trail , i dont have any vpc configs on the Nexus 5k. I have connected two links from the 5k to the 2k , and bundled them to one port channel.

Hi Evans, 

I think I am running into the same issue. What do you mean by a config refresh?
