Type the command that needs to be configured on a switch to automatically recover from the err-disabled state, when caused by port security.

(A) recovery cause psecure-violation
(B) errdisable recovery psecure-violation
(C) errdisable recovery
(D) errdisable recovery cause psecure-violation

errdisable recovery cause psecure-violation is the correct answer.

Once port security has placed a port in the err-disabled state, by default the port remains in an err-disabled state until someone takes action. To recover from an err-disabled state, the interface must be shut down with the shutdown command and then enabled with the no shutdown command.

Alternately, the switch can be configured to automatically recover from the err-disabled state, when caused by port security, with these commands:

1. errdisable recovery cause psecure-violation:
   A global command to enable automatic recovery for interfaces in an errdisabled state caused by port security.
2. errdisable recovery interval seconds:
   A global commandto set the time to wait before recovering the interface.
