Managing management module redundancy

Figure 4 shows how the files are synchronized between the active module and the standby module.
FIGURE 4 Active and standby management module file synchronization
The BigIron RX Series system allows you to do the following related to file synchronization:
•
Compare files on the active module with files on the standby module and immediately
synchronize any files that are different.
•
Immediately synchronize all files between the active and standby modules.
The following sections explain how to perform these tasks.
Comparing and synchronizing files
You can initiate a comparison of the flash code, system-config file, and running-config file on the
active management module with the same files on the standby module and synchronize the files
immediately if differences exist. When you synchronize the files, the active module copies its files
to the standby module, replacing the files on the standby module.
