Actually to see a REASON why a particular interface has been errdisabled there is one command "sh interfaces status err-disable"; there it shows the REASON. Other commands just shows if the particular feature is enabled or disabled state on a switch. Switch#sh int status err-disabled Port Name Status Reason Err-disabled Vlans Fa0/5 err-disabled bpduguard
