After the switch is assigned an IP address and at least one switch port is connected to the network and properly configured, the switch can communicate with other nodes on the network. This communication goes beyond simply switching traffic.

To test connectivity to remote hosts, enter the following command in privileged mode.

> Switch#ping destination ip address

The ping command will return one of the following responses:

- Success rate is 100 percent. This response occurs in 1 to 10 seconds, depending on network traffic and the number of Internet Control Message Protocol (ICMP) packets sent.
- Destination does not respond. No answer message is returned if the host does not respond.
- Unknown host. This response occurs if the targeted host does not exist.
- Destination unreachable. This response occurs if the default gateway cannot reach the specified network.
- Network or host unreachable. This response occurs if there is no entry in the route table for the host or network.

The example in Figure shows that the destination IP address 10.1.1.1 can be reached by the device generating the ping.
