CAM Profile Commands
The CAM profiling feature enables you to partition the CAM to best suit your application. For
example:
• Configure more Layer 2 FIB entries when the system is deployed as a switch.
• Configure more Layer 3 FIB entries when the system is deployed as a router.
• Configure more ACLs (when IPv6 is not employed).
• Hash MPLS packets based on source and destination IP addresses for LAGs.
• Hash based on bidirectional flow for LAGs.
• Optimize the VLAN ACL Group feature, which permits group VLANs for IP egress ACLs.
Important Points to Remember
• CAM Profiles are available on FTOS versions 6.3.1.1 and later for the E-Series TeraScale. Refer
to Chapter 14, Content Addressable Memory (CAM) for ExaScale for information on the
commands for the E-Series ExaScale platform.
• FTOS versions 7.8.1.0 and later support CAM allocations on the C-Series and S-Series.
Note: Not all CAM commands are supported on all platforms. Be sure to note the platform symbol when
looking for a command.
