Verifying network connections

If you want to use the ping command to verify the...

Then...

Host name interface

Complete Steps 2 and 3.

IP address of the interface

Complete Steps 4 and 5.

At a host attached to the network, enter the following command:

ping hostname-interface

hostname is the host name that you assigned to the gateway when you ran the setup program.

interface is one of the interface names that the gateway assigned when you ran the setup program.

Example

This command tests the network connections for a gateway that has the host name "toaster" with an interface named e0 installed:

ping toaster-e0

Repeat the test once for each interface that is installed in the gateway.

At a host attached to the network, enter the following command:

ping hostname-IP_address

hostname is the host name that you assigned to the gateway when you ran the setup program.

IP_address is the IP address that the gateway assigned to that interface during the setup program.

Example

This command tests the network connections for a gateway that has the host name "toaster" with an interface named e0 installed at 172.25.50.10"

ping 172.25.50.10

Repeat the test once for each interface that is installed in the gateway.

Check to make sure that the interface cable is securely attached to the gateway and the switch or router, and that the connection and activity LEDs are lit.

Check to make sure that the media type is set up correctly if the interface is using a multiport Ethernet card with different port speeds.

Check to make sure that the routers function properly with correct routing information if the ping command is issued from a network not directly attached to the interface.
