Or you could do "sh int status err" and it'll even tell you why it's
disabled, which is useful if you forgot to look at (or set up) your log.

3560A#sh int status err

Port Name Status Reason

Either gremlins or err-disabled. i'll vote for #2.

Your logging messages should be telling you WHY it does that. (use "sh
int
| in errd" to take a look around first!)

Typically I see this when people are setting up their trunks or
etherchannels. And if you aren't doing it fast enough (per the switch's
opinion) you'll start to see things shutdown due to port
inconsistencies.

Cut 'n' paste from notepad makes things go faster!

Or just treat it as expected behavior.
