Hello,
I've got a Cisco 3550 12G.
Suddenly the GigabitEthernet0/4 goes down and goes in "err-disabled" mode.
I think to have fixed the problem (probably a bad cable).
Now: how can I re-enable the port?
With CATOS I think "set port enable", but with IOS?
Thank you

Just do a shut/no shut under the interface. THe switch would normally log the reason for err-disabling. Check output of sh log

The fact that you have it set for auto speed and auto duplex can cause it to go int err if it is having trouble negotiating.

Hello,
I shutted down/up the interface. After I have configured the "errdisabled recovery ...", but my interface is now in the "notconnect" status with both interface and line protcol down:

Could you give me any suggestion?
Thank you
