CAM Profile Description
Available Microcodes: default.
unified-default Maintains the CAM allocations for the IPv4 FIB while allocating more CAM space for the
Ingress and Egress Layer 2 ACL and IPv4 ACL regions.
Available Microcodes: ipv6-extacl.
ipv4-64k-ipv6 Provides IPv6 functionality; an alternate to ipv6-extacl that redistributes CAM space from the
IPv4FIB to IPv4Flow and IPv6FIB.
Available Microcodes: ipv6-extacl.
The size of CAM partitions is measured in entries. The following table shows the number of entries available in each
partition for all CAM profiles. The total CAM space is finite — 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 Networking 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).
