An interface was configured as follows:
Didcot(config)#int fa 0/0
Didcot(config-if)#ip address 192.168.4.8 255.255.255.0
Didcot(config-if)#exit
A ping to this interface fails.
Which command would be the best choice to identify the problem?
Show int fa 0/0
Show interfaces serial
Show version
Show startup-config
