Today I experimenting a very strange situation... An extender-AccessPoint from tp-link brand disables ports for a 9200 Catalyst switch with the error of "err-disabled" due to loopback error detected.. I updated the tp-link device firmware and still peoduces same behavior, this was a RE450 model but with RE455 doesn't happens so maybe some bads on code about specifications RFCs or whatever... maybe a bug in iOS Cisco firm but thats rare. Will capture some traffic to look for some culprit

to enable ports again you know.. issuing commands "shutdown" problematic interface and "no shutdown" to come alive again did the trick
Wow that's crazy. Good spot.
