Content Addressable Memory | 267
The size of CAM partitions is measured in entries. Table 13-1, "CAM Profile Descriptions," in Content
Addressable Memory shows the number of entries available in each partition for all CAM profiles. The
total CAM space is finite, therefor adding entries to one region necessarily decreases the number available
to other regions.

ipv6-extacl Provides IPv6 functionality.
Available Microcodes: ipv6-extacl
l2-ipv4-inacl Provides 32K entries for Layer 2 ingress ACLs and 28K entries for Layer 3 IPv4 ingress ACLs.
Available Microcodes: default
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-VRF Provides VRF functionality for IPv4.
Available Microcodes:ipv4-vrf
ipv4-v6-VRF Provides VRF functionality for both IPv4 and I.Pv6
Available Microcodes: ipv4-v6-vrf
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
