Hello all, I've a 3550-24 switch with a port shut down due to excessive errors. As a newbie to configuration, what's the command to re-enable the port? I've tried to figure it out with no sucess. Thanks In Advance

it is simple...
once you are connected to the switch just type 'en' (input the password), type 'confit t' (this will put you to a configuration mode...)
for example you need to configue port 1. type 'int fastethernet 0/1'
now input 'no shut' command, hit 'ctrl + Z', type 'wr mem' or 'copy run start'.
you are done...
i hope that is what you needed... if port is still down check the connectivity on the other end.. you may also be having a hardware problem.

Tried the command you suggested, it had no effect, the p ort still shows as errdisabled.

Try 'shutdown' on the port first before you issue the 'no shutdown' command.
Also, and this is perhaps more obvious, fix the fault that caused the port to enter errdisable state in the first place. If you don't do that, it will instantly go back into errdisable again. If you don't know what's causing the port to shutdown, make sure you have 'errdisable detect cause all' enabled. If you do this you can use the 'show errdisable detect' command to see why it's being shutdown.

KiscoKid, thanks that worked like a charm. I checked the logs for the cause but didn't see anything. I'll make a note of that point.
