Jamil,

Bpduguard will make the port go into err-disable if it receives bpdus on the port. You should see in the logs why it went into err-disable though, but if it's because of receiving a bpdu you'll need to find out if there's an unauthorized switch put on your network.

HTH,

John

Good thinking.  Use the command "sh interface status error" will show you the reason why the port went into error-disable.
