On Dell Force10 systems, the microcode controlshow packets are handled.There is a default microcode, and several other microcodes are available, so that you can adjust packethandling according to your application. Specifying a microcode is mandatory when selecting a CAMprofile (though you are not required to change it).Table 11-2.

Microcode DescriptionsMicrocode Descriptiondefault Distributes CAM space for a typical deploymentlag-hash-align For applications that require the same hashing for bi-directional traffic (for example, VoIPcall or P2P file sharing). For port-channels, this microcode maps both directions of abi-directional flow to the same output link.
