Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
redundancy config-sync mismatched-commands
If SSO mode cannot be established between the active and standby supervisor engines because of an
incompatibility in the configuration file, a mismatched command list (MCL) is generated at the active
supervisor engine and a reload into RPR mode is forced for the standby supervisor engine. Subse quent
attempts to establish SSO, after removing the offending co nfiguration and rebooting t he standby
supervisor engine with the exact same image, might cause the
C4K_REDUNDAN CY-2-IOS_VE RSION _CHECK_FAI L and
ISSU-3-PEER_IMAGE_INCOMPATIBLE messages to appear because the peer image is listed as
incompatible. If the configuration problem can be corrected, you can clear the peer image from the
incompatible list with the redundancy config-sync ignore mismatched-commands EXEC command
while the peer is in a standby cold (RPR) state. This action allows the standy s upervisor engine to boot
in standby hot (SSO) state when it relo ads.
Examples This example shows how to validate removal of entrie s from the MCL:
