CAM Allocation and CAM Optimization The S5000 supports the following: • User Configurable CAM Allocations • CAM optimization User-Configurable CAM Allocation You can re-allocate memory space for IPV6 ACLs by using the cam-acl command in CONFIGURATION mode. CAM space is allotted in FP blocks. The total allocated CAM space must equal 13 FP blocks. Note that there are 16 FP blocks, but the System Flow requires 3 blocks that cannot be reallocated. The default CAM allocation settings for ingress ACL and QoS regions on an S5000 are: • L2 ACL(l2acl): 4 • L3 ACL (ipv4acl): 4 • IPv6 L3 ACL (ipv6acl): 0 • L3 QoS (ipv4qos): 2 • L2 QoS (l2qos): 1 • L2PT (l2pt): 0 • MAC ACLs (ipmacacl): 0 • ECFMACL (ecfmacl): 0 • VMAN QoS (vman-qos): 0 • VMAN Dual QoS (vman-dual-qos): 0 • FCoE ACL (fcoeacl): 2 • iSCSI Opt ACL (iscsioptacl): 0 The ipv6acl allocation must be entered as a factor of 2 (2, 4, 6, 8, 10). All other profile allocations can use either even or odd numbered ranges. You must save the new CAM settings to the startup-config (write-mem or copy run start) then reload the system for the new settings to take effect. For more information, see Re-allocating CAM for Ingress ACLs and QoS. CAM optimization CAM optimization is supported on the S5000 platform. When this command is enabled, if a Policy Map containing classification rules (ACL and/or dscp/ ip-precedence 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 will be used). When the command is disabled, the system behaves as described in this chapter. Access Control Lists (ACLs) | 115
