The Switch Module Layer
Chassis Management Module (CMM) is a central management unit that provides key services to manage and coordinate the operations of the Alcatel-Lucent switch. For CMM redundancy, two fully operational CMM modules are installed in the chassis at all times in two available slots.
Using the tests available in this layer, the administrator can identify if there is a CPU resource contention, what is the average CPU usage currently in the last one minute. the administrator can also find out if the memory utilization is optimal and if I/O racecourses are being used properly.
