Hi,
I have a Cisco CBS3020-HPQ chassis switch running IOS 12.2.(25r)SEF3. One of the ports is in "disabled" state but when I try to unshut it, it doesn't work, the switch logs shows the following event:
%PLATFORM_ENV-3-LOOPBACK_PORT_POST_ERR: Gi0/1 can't be brought up because it failed POST in Loopback test
I'm not sure why this is happening, does anyone know what might cause this and how do I resolve this, the port is unusable since I can not get it out "disabled" state.
Any replies would be appreciated.
Thanks,
Sayed
