What switch? Switch 1 or 2? Can you shed some light with "working randomly"?

Just a note ... Your config has alot of "strange" lines:

udld aggressive

errdisable recovery cause udld

Comment: Why put UDLD Aggressive on when you enable automatic port recovery?

spanning-tree portfast bpduguard default

errdisable recovery cause bpduguard

Comment: Why enable BPDU Guard when you enable automatic port recovery?

Just a note.

Hi,

The lights also not shed in the switch.if u connect the power cable again, it is working.

Its a campus network the switches are connected in the remote side for administrator overhead, we enabled these command. u are suspecting any physical layer issue.
