I noticed a strange behavior, sometimes interfaces on N1K goes in suspended status
sv4025-01# sh interface ethernet 17/18
Ethernet17/18 is down (suspended)
and on the cisco switch where is connected I have duplex mismatch
111233: Aug 28 11:20:12.819: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on TenGigabitEthernet1/6 (not half duplex), with sv4025-01.ti.ch(1298652659127955650) Ethernet17/18 (half duplex).
I have some questions:
interface goes in suspended state due to the duplex mismatch ?
How can I have duplex mismatch on 10G interface, as from my knowledge you can't have half duplex on 10G ?
Can you please let us know which version you are running and some insight into the topology? What device is N1k running on and what is the upstream switch?
