Usage Guidelines When two versions of Cisco IOS images are involved, the command sets supported by two images might
differ. If any of those mismatched commands are executed on the active supervisor engine, the standby
supervisor engine might not recognize those commands. This causes a config mismatch condition. If the
syntax check for the command fails on standby supervisor engine during a bulk sync, the command is
moved into the MCL and the standby supervisor engine is reset. To display all the mismatched
commands, use the show redundancy config-sync failures mcl command.
show redundancy config-sync {failures | ignored} {bem | mcl| prc}
show redundancy config-sync ignored failures mcl
Displays MCL entries or BEM/PRC failures.
Displays the ignored MCL entries.
(Deprecated)
Displays commands that exist in the active supervisor engine's running configuration,
but are not supported by the image on the standby supervisor engine.
Displays a Parser Return Code (PRC) failure and forces the system to operate in RPR
mode provided there is a mismatch in the return code for a command execution at the
active and standby supervisor engine.
