We see a considerable decrease of traffic, it seems it is caused by the upgrade on fra-1/5-a9 or fra-1/5-n7. We are continuing our investigations with Cisco.

We are still analyzing the issue with Cisco, but we are thinking that we have found a bug which is cause an over-superscription on the VOQs (Virtual Output Queues) of fra-1-n7 / fra-5-n7 since the last update.

We can't find the root cause of these drops on the VOQ. We are going to isolate fra-5 and reload the Nexus 7 and see if it is going to fix.

Done.

After we've rebooted fra-1-n7, one linecard is not rebooting. We open a ticket to our constructor.
