After a troubleshoot, we noticed that many ports on different routers have the same symptoms. It is therefore likely that there is a fault on one of the switches: pcc-1b-n7. We must now determine whether it's an optical or hardware issue.

We have changed 2 optics on the nexus 7000. We don't notice any up/down so far. There is no longer any CRC (Cyclic Redundancy Check) on ports.

We are monitoring.

We have also noticed that CRC on rbx-s5/s6-6k.
We think that pcc-1b-n7 optics sent CRCs due to the heat.

We are going the change the optics and increase the cooling for n7.

There is currently no CRC present.

We are monitoring.

CRC have not increased in 2 days.
