Nexus2K port cannot be up

[wfqk]

Hi Nesus5K is connected to Nexus2K with fex. Not sure Nexus2K port is broken. When PC is plugged into the port111/1/31 and 32 etc, PC NIC does not show the port is up. Finally we found all ports with command “switchport access vlan 2” have this problem. Other ports are able to be up once PC is plugged into ports with command “switchport access vlan 3”. All ports are no shutdown. Do you think it is switch ports problem or vlan issue? Thank you

Should not be a VLAN issue. With a PC port being up in VLAN 3 try changing it to VLAN 2 and see if it goes down

Thank you for your reply. it is strange. All the ports being vlan2 are not be able to be up except ports with vlan2 that are being used. we need to be pretty clear about this issue before making change for test as it is production environment. maybe it is a bug, which needs TAC help
