Using Ping
Understanding Ping
The switch supports IP ping, which you can use to test connectivity to remote hosts. Ping sends an echo
request packet to an address and waits for a reply. Ping returns one of these 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.
•
Destination unreachable—If the default gateway cannot reach the specified network, a
destination-unreachable
message is returned.
•
Network or host unreachable—If there is no entry in the route table for the host or network, a
network or host unreachable
message is returned.
Executing Ping
If you attempt to ping a host in a different IP subnetwork, you must define a static route to the network
or have IP routing configured to route between those subnets. For more information, see
“Configuring IP Unicast Routing.”
IP routing is disabled by default on all switches. If you need to enable or configure IP routing, see
Chapter 38, “Configuring IP Unicast Routing.”
Beginning in privileged EXEC mode, use this command to ping another device on the network from the
switch:
Note
Though other protocol keywords are available with the
ping
command, they are not supported in this
release.
