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).

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

Microcode Description
default Distributes CAM space for a typical deployment
lag-hash-align 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.
