What is the default value for the errdisable recovery interval in a Cisco switch?

A.
30 seconds

B.
100 seconds

C.
43sernads

D.
600 seconds

Explanation:
After you fix the root problem, the ports are still disabled if you have not configured errdisable recovery on the switch. In this case, you must reenable the ports
manually. Issue the shutdown command and then the no shutdown interface mode command on the associated interface in order to manually reenable the ports.
The errdisable recovery command allows you to choose the type of errors that automatically reenable the ports after a specified amount of time. The show
errdisable recovery command shows the default error-disable recovery state for all the possible conditions.
