Content Addressable Memory (CAM) | 257
The size of CAM partitions is measured in entries. Table 10-1 shows the number of entries available in
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).

For applications that require the same hashing for bi-directional traffic (for
example, VoIP call or P2P file sharing). For port-channels, this microcode maps
both directions of a bi-directional flow to the same output link.
