I had a port get disabled because of a feedback loop. Plugged it back Iin and cannot re-enabled via CNA
Is there a command to re-enable the port
The document i found suggest using the shut down then no shut down command
Is that safe ? will it kick all ports ?
Cisco Catalyst 3750
We can use 'shut' , 'no shut' and we can configure the switch to recover automatically.
Commands are as follows:
errdisable detect cause command 2-140
errdisable detect cause small-frame comand 2-143
errdisable recovery cause small-frame 2-145
errdisable recovery command 2-146
error conditions, displaying 2-469

Hope this helps!
Yes, Just do a sh and no sh on that port. That should enable the port again.
