If an interface does not respond to a ping command, make sure that:
The interface is securely attached to the network.
The media type is set up correctly if the interface is using a multi-port Ethernet
card with different port speeds.
The routers function properly with correct routing information if the ping com-
mand is issued from a network not directly attached to the interface.
