Changing the Working Microcode Image
Caution Configuring topology discovery or shortest path load balancing on an ML-Series card with the SW-RPR
microcode image disables support for Cisco Proprietary RPR DRPRI.
Changing the Working Microcode Image
The user can change the microcode image using Cisco IOS CLI configuration and a reset of the
ML-Series card. Using this configuration method, you can load any mi crocode image except 802.17. To
automatically download and enable the 802.17 microcode image, use CTC to set the card mode to
802.17. For more information, see the “Provisioning Card Mode” section on page 2-4.
To configure a working microcode image, perform the following procedure, beginning in global
configuration mode:
