Synchronizing the Configurations (Catalyst8540MSR)
Caution If no system image is specified in the startup configuration, the ROM monitor automatically boots the
first system image on the Flash PC card in slot0. If there is no system image on the Flash PC card, or the
Flash PC card is not available, the ROM monitor boots the first system image in bootflash. If there is no
system image in bootflash, the switch remains in ROM monitor mode.

Displaying the Configuration Register Value

To display the configuration register value, use the following privileged EXEC command:
The following example shows the configuration register value:

Synchronizing the Configurations (Catalyst 8540 MSR)
During normal operation, the startup and running configurati ons are synchronized by default between
the two route processors. In the event of a switchover, the new primary route processor uses the current
configuration. Configurations synchronize either immediately from the command line or during route
processor switchover.
