Example of the cam-profile default Command Dell(conf)#cam-profile ? default Enable default CAM profile eg-default Enable eg-default CAM profile ipv4-320k Enable 320K CAM profile ipv4-egacl-16k Enable CAM profile with 16K IPv4 egress ACL ipv6-extacl Enable CAM profile with extended ACL l2-ipv4-inacl Enable CAM profile with 32K L2 and 28K IPv4 ingress ACL unified-default Enable default unified CAM profile Dell(conf)#cam-profile default microcode ? default Enable default microcode lag-hash-align Enable microcode with LAG hash align lag-hash-mpls Enable microcode with LAG hash MPLS Dell(conf)#cam-profile default microcode default Dell(conf)#cam-ipv4flow ? default Reset IPv4flow CAM entries to default setting multicast-fib Set multicast FIB entries Dell(conf)#cam-l2acl ? default Reset L2-ACL CAM entries to default setting system-flow Set system flow entries CAM Optimization The cam-optimization command allows you to optimize CAM utilization for QoS entries by minimizing the amount of required policy-map CAM space. When you enable this command, if a Policy Map containing classification rules (ACL and/or dscp/ ipprecedence rules) is applied to more than one physical interface on the same port-pipe, only a single copy of the policy is written (only 1 FP entry is used). When you disable this command, the system behaves as described in this chapter. Applications for CAM Profiling The following describes link aggregation group (LAG) hashing. LAG Hashing The Dell Networking OS includes a CAM profile and microcode that treats MPLS packets as non-IP packets. Normally, switching and LAG hashing is based on source and destination MAC addresses. Alternatively, you can base LAG hashing for MPLS packets on source and destination IP addresses. This type of hashing is allowed for MPLS packets with five labels or less. MPLS packets are treated as follows: • When MPLS IP packets are received, the system looks up to five labels deep for the IP header. • When an IP header is present, hashing is based on IP three tuples (source IP address, destination IP address, and IP protocol). 248 Content Addressable Memory (CAM)
