Nexus 7k vpc suspend

Problem: Moving uplink interfaces on 3750 Dist to 4500x

              Uplink devices are Nexus 7k

                            I see vpc “suspended” on one of the Nexus 7K port-chanel interfaces

                            Only 1 Layer 2 uplink works on 4500x

                             Both Layer 2 Uplinks work on 3750

 

Have swapped out SFP’s, no change!

 

Your expert advise will be much appreciated

From the 4500x to 7ks, are both physical links up?

On both 7ks, under the Portchannel interface can you do a "sh" and "no sh"?

If that does not work, then do this:

shut the po interface

shut the physical interfaces

than

do "no shut" under the Po.  This should bring up all the physical interfaces and the po.

This is all if the 4500x config is correct.

Also, can you post the config from the 4500 and also post the output of "sh port-cha summary"?

Thank you for the response.

We tried that.

 

We first connected Te1/2/8 on 4500x to Nexus 7k. That int came up fine.

We then connected Te2/2/8 on 4500 no lights. on interface

We changed SFP's, no change.

We changed interfaces on 4500x, no change.
