Chapter 3 Initial Configuration
Changing the Working Microcode Image
To configure a working microcode image, perform the following procedure, beginning in global
configuration mode:
Command Purpose
Step 1
Router(config)# microcode {base | enhanced
| fail | mpls | spr}
Configures the ML-Series card with the selected
microcode image:
base—(Default) Enables base features only. Base
features include Multicast routing and IP
fragmentation.
enhanced—Enables ERMS, enhanced packet
statistics, and enhanced DRPRI. Disables
multicast routing and IP fragmentation.
fail—This command and feature are specific to
ML-Series cards. In the event of a microcode
failure, it configures the ML-Series card to save
information to the flash memory and then reboot.
The information is saved for use by the Cisco
Technical Assistance Center (Cisco TAC).
To
contact Cisco TAC, see Appendix C, “Using
Technical Support.”.
mpls—Enables MPLS. Disables IP multicast, IP
fragmentation, and Ethernet relay multipoint
service (ERMS) support.
spr—Enables Cisco proprietary RPR
encapsulation, Enhanced Packet Statistics,
DRPRI, and Keepalives. Disables Multicast
routing or IP fragmentation.
Step 2
Router(config)# exit
Exits global configuration mode.
Step 3
Router# copy running-config startup-config
Saves the configuration changes to flash memory.
The running configuration file configured with the
new microcode image choice must be saved as a
startup configuration file for the ML-Series card to
reboot with the new microcode image choice.
Step 4
Router# reload
Resets the ML-Series card and loads the new
microcode image.
Caution Resetting the ML-Series card causes a
loss of traffic and closes any Telnet
sessions to the card.
Step 5
Router# show microcode
Shows the microcode image currently loaded and
the microcode image that loads when the
ML-Series card resets.
