Hi all,
Just to preempt, I recommended against an SG switch but was told they wanted to be at 10G and this was the only switch that fit the budget. Every time I have to work on it I bang my head and hope to die.
So this morning at 3 AM I got a call that many things were unavailable. It was determined that a port on this switch stopped passing traffic properly. Here is the show int counter te1/0/7 output.
Port InUcastPkts InMcastPkts InBcastPkts InOctets ---------------- ------------ ------------ ------------ ------------ te1/0/7 1304018547 6775514 15671865 104077349244 37 Port OutUcastPkts OutMcastPkts OutBcastPkts OutOctets ---------------- ------------ ------------ ------------ ------------ te1/0/7 1691945037 60074188 50132448 210168822080 2 FCS Errors: 0 Single Collision Frames: 0 Multiple Collision Frames: 0 SQE Test Errors: 0 Deferred Transmissions: 0 Late Collisions: 0 Excessive Collisions: 0 Carrier Sense Errors: 0 Oversize Packets: 0 Internal MAC Rx Errors: 174264 Symbol Errors: 0 Received Pause Frames: 0 Transmitted Pause Frames: 0
Obviously Internal MAC Rx Errors shouldn't be non-zero. Could anyone give me some info on what this metric may indicate? I can't find any good Cisco-specific information (though it looks like this may legitimately actually be a Dell switch/OS?). Thanks for any info or ideas!
Edit: it appears the issue has moved with the port that they moved to, so I'm thinking a bad SFP on one side or the other, or a bad fiber. Does that sound like it'd exhibit this behavior?
