Ethernet Interface Processor (EIP) Installation and Configuration 31
Upgrading Microcode
Using Show Commands to Verify the EIP Status
The following summary describes how to use the show commands to verify that the new interfaces
are configured correctly:
Step 1 Use the show version command to display the system hardware configuration. Ensure that
the list includes the new Ethernet interfaces.
Step 2 Display all the current interface processors and their interfaces with the show controllers
cxbus command. Verify that the new EIP appears in the correct slot.
Step 3 Specify one of the new Ethernet interfaces with the show interfaces ethernet slot/port
command and verify that the first line of the display specifies the interface with the correct
slot number. Also verify that the interface and line protocol are in the correct state: up or
down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the
command show protocols. If necessary, return to the configuration mode to add or remove
protocol routing on the system or specific interfaces.
Step 5 Display the entire system configuration file with the show configuration command. Verify
that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is
not functioning properly, ensure that the network interface is properly connected and terminated. If
you still have problems bringing the interface up, contact a customer service representative for
assistance.
This completes the configuration procedure for the new Ethernet interfaces.
Upgrading Microcode
The Cisco 7000 series and Cisco 75000 series routers support downloadable microcode, which
enables you to upgrade microcode versions without having to physically replace the EPROMs on the
boards. You can download new microcode versions and store multiple versions in Flash memory,
and you can boot from them just as you can with the system software images. System software
upgrades may also contain upgraded microcode images, which will load automatically when the new
software image is loaded.
This section describes how to use and configure downloadable microcode and, if necessary, how to
replace the microcode EPROM on the EIP.
Downloading Microcode to Flash Memory
You can 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 can use the microcode
reload command to manually load the new microcode file, and the configure command to instruct
the system to load the new image automatically at each system boot.
In order to compare the size of the microcode image and the amount of Flash memory available, you
must know the size of the new microcode image. The image size is specified in the README file
that is included on the floppy disk with the new image. Note the size of the new image before
proceeding to ensure that you have sufficient available Flash memory for the new image.
