VIP in Cisco 7500 Series Routers—Example Output of the show interfaces Command

Following is an example of the show interfaces pos command used with the VIP. In this example, the pos interfaces is on a port adapter in port adapter slot 1 of a VIP in interface processor slot 1. Most of the status information for each interface is omitted. (Interfaces are administratively shut down until you enable them.)

Using the ping Command to Verify Network Connectivity

You can use the ping command to verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the “Related Documentation” section on page viii for detailed command descriptions and examples.

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages (timed out) or (failed) indicate a

bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return>

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#
