each partition for all CAM profiles. The total CAM space is finite, therefore adding entries to one region

necessarily decreases the number available to other regions.

Microcode

Microcode is a compiled set of instructions for a CPU. On Dell Force10 systems, the microcode controls

how packets are handled.

There is a default microcode, and several other microcodes are available, so that you can adjust packet

handling according to your application. Specifying a microcode is mandatory when selecting a CAM

profile (though you are not required to change it).

Note: Not all CAM profiles and microcodes are available for all systems. Refer to the Command Line

Interface Reference Guide for details regarding available profiles for each system.
