When to Use CAM Profiling
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. Refer to LAG Hashing.
• Hash based on bidirectional flow for LAGs. Refer to LAG Hashing based on Bidirectional Flow.
• Optimize the VLAN ACL Group feature, which permits group VLANs for IP egress ACLs. Refer to
CAM profile for the VLAN ACL group feature.
