Using the ping Command to Verify Network Connection
For a Catalyst RSM/VIP2, use the show controllers cbus command to display all of the current interfaces. Following is an example of the show controllers cbus command that shows serial port 0/0 on a
router# show controllers cbus

Note The slot values displayed by some commands (such as show diag and show controllers cbus) are not relevant to any physical connection; please disregard these slot values for the Catalyst RSM/VIP2.
For complete command descriptions and examples for the Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, the VIP2, and the Catalyst RSM/VIP2, refer to the publications listed in the “Related Documentation” section on page vi.
Using the ping Command to Verify Network Connection
The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. For example, after you verify that the system and VIP2 have booted successfully and are operational, you can use the ping command to verify the status of interface ports. Refer to the publications listed in the “Related Documentation” section on page vi for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal;
