VIP4 Maintenance Procedures

Using the ping Command to Verify Network Connectivity

This section provides brief descriptions of the ping command. 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. After you verify that the system and VIP4 have booted

successfully and are operational, you can use this command to verify the status of the VIP4 interface

ports. Refer to the publications listed in the

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; each signal 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 that the connection failed.

Following is an example of a successful ping command to a remote server with the IP address 10.1.1.60:

Router# ping 10.1.1.60 <Return>

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.1.1.60, timeout is 2 seconds:

!!!!!

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

Router#

If the connection fails, verify that you have the correct IP address for the server and that the server is

active (powered on), and repeat the ping command.

For complete descriptions of interface subcommands and the configuration options available for

VIP4-related interfaces, and which commands support VIP4 functionality, refer to the publications listed

in the

VIP4 Maintenance Procedures

The following sections discuss maintenance procedures you might need for your VIP4 and port adapters:

•

Upgrading VIP4 Microcode

The Cisco 7000 series and Cisco 7500 series routers support downloadable microcode, which enables

you to upgrade microcode versions over the network. You can download new microcode versions and

store multiple versions in Flash memory, and you can then boot from them just as you can with the

system software images. System software upgrades might also contain upgraded microcode images,

which will load automatically when the new software image is loaded (unless the configuration states

otherwise).
