This completes the procedure for configuring microcode. For complete descriptions of the show
commands, refer to the publications listed in the section "If You Need More Information" on page 2.
Using Flash Memory
The following sections discuss various Flash-memory functionality that you might need.
Copying to Flash Memory on an RSP or RSP7000
Copying a new image to Flash memory might be required whenever a new microcode image
becomes available. Use the command copy tftp:filename [ bootflash | slot0 | slot1 ]:filename for the
copy procedure where tftp:filename is the source of the file and [ bootflash | slot0 | slot1 ]:filename
is the destination in onboard Flash memory or on either of the Flash memory cards.
An example of the copy tftp:filename command for Cisco IOS Release 11.1 follows:
Router# copy tftp:cip1234 slot0:cip1234
2283972 bytes available on device flash, proceed? [confirm]
Address or name of remote host [hamachi.cisco.com]?
Accessing file "cip1234" on hamachi.cisco.com ...FOUND
Loading mhoerler/cip1234 from 1.1.1.22 (via Ethernet0/0): !Verifying via checksum...
Flash verification successful.

In privileged command mode, enter router configuration mode and specify that the console
terminal will be the source of the configuration subcommands, as follows:
Router# configure terminal
To load the microcode from an individual microcode image that is stored as a file in Flash
memory, enter the microcode command, the processor type, the specific memory location
of the CIP2 microcode image, and the exact argument for filename (cip1234 is used in this
example):
Router(config)# microcode cip flash slot0:cip1234
The no microcode command cancels any existing instructions to load an image from Flash
memory:
Router(config)# no microcode cip flash slot0:cip1234
To save the configuration file, press Ctrl-Z, then copy the new configuration to nonvolatile
random-access memory (NVRAM) as follows:
Router# copy running-config startup-config
The microcode reload command must invoked whenever you modify the system default
to load a microcode image, using the microcode cip flash command.
To verify that the correct microcode is loaded according to the new instructions, enter the
show controller cbus EXEC command. The resulting display indicates the currently
loaded and running microcode version for each interface processor.
To verify the contents of the configuration file, enter the show running-config and show
startup-config EXEC commands. You can also verify that the correct system image is
configured to load at system restart or reload.
