Using Ping
These sections describe how to use IP ping:
• Understanding How Ping Works, page 10-7

Running Ping, page 10-8
Understanding How Ping Works
The ping command allows you to verify connectivity to remote hosts. If you attempt to ping a host in a
different IP subnetwork, you must define a static route to the network or configure a router to route
between those subnets.
The ping command is configurable from normal executive and privileged EXEC mode. Ping returns one
of the following responses:
• Normal response—The normal response ( hostname is alive) occurs in 1 to 10 seconds, depending
on network traffic.
•
Destination does not respond—If the host does not respond, a No Answer message is returned.
• Unknown host—If the host does not exist, an Unknown Host message is returned.
Command Purpose
Switch# disconnect { console | ip_addr }
Disconnects an active user session on the switch.
