Upgrading FEIP Microcode

Using the ping Command to Verify Network Connectivity

Thepacket internet groper (ping) command allows you to verify that an interface port is functioning

properly and to check the path between a speciﬁc port and connected devicesat various locations on

the network.This section provides brief descriptions of the ping command. After you verify that the

system and FEIP havebooted successfully and are operational, you can use this command to verify

the status of interface ports. Refer to the publications listed in the section “If You Need More

Information” on page 2, 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;

each signal that is not returned before the speciﬁed time-out 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.

Followingis an example of a successful ping command to a remote server with the address 1.1.1.10:

Router# ping 1.1.1.10 <Return>

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 1.1.1.10, 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

FEIP-related interfaces, and which support FEIP functionality,refer to the publications listed in the

section “If You Need More Information” on page2.

Upgrading FEIP Microcode

TheCisco 7000 series and Cisco 7500 series routers support downloadable microcode, which allows

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 load automatically when the new softwareimage is loaded (unless the conﬁguration

states otherwise).

Note Software and interface processor microcode images are carefully optimized and bundled to

worktogether. Overriding the bundle can result in system incompatibilities. Werecommend that you

use the microcode included in the software bundle.

Youcan download microcode to Flash memory by copying the TFTP image of a microcode version

to Flash memory.When the microcode image is stored in Flash memory, you have to conﬁgure the

router to use that image via the microcode vip2 ﬂash command, then you can use the

microcode reload command to manually load the new microcode ﬁle. You can then use the

conﬁgurecommand to instruct the system to load the new image automatically at each system boot.

Note The appropriate microcode image runs from dynamic random-access memory (DRAM) on

the FEIP.
