CISCO 3550 - Port Error Disabled
We have a CISCO 3550 with several ports that have a status of "Port is error disabled". Is there a way I can clear the error to make the ports usable again without restarting the switch?
I guess the second part of the question might be what could cause the port to go into such a state and is there perhaps a way to get them to auto reset after a brief time?

When the source of the problem is fixed, the ports do not automatically become enabled again. Once the source of the problem is fixed, the ports are still disabled (and the port LEDs are still orange); the ports must be reenabled before they become active.
To reenable the interface manually, issue the shutdown and no shutdown interface commands. You can also issue the errdisable recovery cause enable command to set up timeout mechanisms that automatically reenable the port after a configured time period.
Issue the errdisable recovery cause bpduguard and errdisable recovery interval sec commands to reenable the port automatically.
