Content Addressable Memory (CAM) | 263
The size of CAM partitions is measured in entries. Table 11-1 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.
unified-default Maintains the CAM allocations for the and 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
