To synchronize the secondary CMM to the primary CMM, enter the following command at the prompt:
-> copy flash-synchro
command is described in detail in the OmniSwitch CLI Reference Guide.
Note. When synchronizing the primary and secondary CMMs, it is important to remember that the
boot.params file and the switch date and time are not automatically synchronized. See the Getting Started
Guide for information on the boot.params file, and
boot.params file and the switch date and time are not automatically synchronized. See the Getting Started
Guide for information on the boot.params file, and
for information
on setting the switch date and time. The date and time are synchronized using the
command.
Synchronizing the System Date and Time
To synchronize the system date and time, use the
command synchronizes the secondary CMM date and time to the primary CMM date and time.
Enter the command as shown:
-> system time-and-date synchro
CMM Switching Fabric
Each OmniSwitch Chassis-based CMM module contains hardware and software elements to provide
management functions for the switch. The CMM module also contains the switch fabric for the system.
User data flowing from one NI module to another passes through the switch fabric.
management functions for the switch. The CMM module also contains the switch fabric for the system.
User data flowing from one NI module to another passes through the switch fabric.
The switch will operate with one or two CMM modules installed.
If there are two CMM modules, one management processor is considered “primary” and is actively
managing the system. The other management processor is considered “secondary” and remains ready to
quickly take over management in the event of hardware or software failure on the primary. In the event of
a failure, the two processors exchange roles and the secondary takes over as primary.

The switch fabric on the CMM operates independently of the management processor. If there are two
CMM modules installed, both fabric modules are normally active. Two CMM modules must be installed
in the switch to provide full fabric capacity.

If there is one CMM module installed, then there is a single management feature and performance as a
dual CMM system, but there is no “secondary” CMM. Hardware or software failures in the CMM will
result in a system reboot. The System fabric capacity is on half of the fabric capacity of a dual CMM
system.
