Hi,
I cheked my logs and found out below...
I am assuming it is a cabling issue ??? please confirm....
are there any issues with the configs???

Hi,
The logs are indicating that the FEX is not receiving LACPDU from the server. Check with the server team to make sure they've configured the server to use 802.3ad Link Aggregation with LACP, sometimes called 802.3ad dynamic.
If the server only supports static link aggregates, then you should reconfigure the FEX ports with the channel-group 220 mode on command.
Regards

Steve,
Thanks for the reply....
but what about "link failure" logs ??? is it layer-1 issue ??? i see it happens for every few minutes.

Hi,
What's the upstream Nexus switch? The Nexus 7000 has a feature called lacp suspend-individual enabled by default which will disable the physical interface if LACPDU are not being received.
The timings don't look exactly as I'd expect, but I'm struggling to believe that all four links are flapping due to cable issues.
Can you paste the output of show lacp summary and show lacp counters when the links are operational and when they're down? I'm interested to see how things behave once the LACP issues are resolved.
Regards

The number of received LACPDU is 0 (103/1/21) or 60 (1/22 and 1/23) and so much less than it should be. I would resolve this issue first by either getting the server to run IEEE 802.3ad with LACP or to change the interface settings on the FEX to use channel-group 220 mode on.
If the interfaces are still changing state after correcting this we can then look to see what else it might be.

What I saw as I walked up to the cabinet. All four connections were lit solid. All four went out at the same time. I checked all connections to make sure they were all seated correctly, both at the cabinet and at the idf, and they were. I watched the connections at the back of the cabinet for almost 4 minutes before they all went out again. I then watched at the switches and after about a minute at that point the links went down for approx. 3 seconds then came back on all at the same time.
