Hi experts,
Recently I found there is high transmit error from few nexus 5548 interface from my monitoring system. You may see from the attached image.
I tried to use snmpwalk to walk and below is the result.
IF-MIB::ifDescr.436211712 = STRING: Ethernet1/2
IF-MIB::ifOutErrors.436211712 = Counter32: 6308517
Seems there is error occur so I log in switches and check the interface:
Ethernet1/2 is up

Based on the result in the switches, I can't see any error occur.
Can anyone give some advise on this ?
Thank you very much in advance.

Greetings.
That sounds like a bug.
I found a similar one for the UCSM, but haven't found one describing your specific counter issue for the N5k.
What code level are you running?
You may want to open a TAC ticket, and see if they can ID the bug, and fixed in version (if one exists).
Thanks,
Kirk...

Hi,
I am logging at notification level. Maybe will open a TAC case and check with support.
Thanks for your advise. :)
