When executing the command "show ip interface []" for the Switch port Fastethernet 0/1, the state for such port is currently "ErrDisabled". What is the first thing to do in order to recover the port?
Restart the Switch.
Use the command "clear errdisabled" on the Fe0/1 port.
Execute the "reload" command.
Execute the "shutdown" followed by "no shutdown" under the Fe0/1 interface.
Verify the reason of the problem.
An ErrDisable state port may be because by different causes, such as encapsulation mismatch, protocol mismatch, or negotiation misconfiguration. A reload of the switch or the port may not fix the issue. For more information refer to: http://www.cisco.com/c/en/us/support/docs/lan-switching/ethernet/12006-chapter22.html#backinfo
