Dell Force10 E1200i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 133

For information regarding E-Series ExaScale CAM-profile templates and their support of ACLs, refer to Chapter 14, Content Addressable Memory for ExaScale. The default CAM profile has 1K Layer 2 ingress ACL entries. If you need more memory for Layer 2 ingress ACLs, select the profile l2-ipv4-inacl. When budgeting your CAM allocations for ACLs and QoS configurations, remember that ACL and QoS rules might consume more than one CAM entry depending on complexity. For example, TCP and UDP rules with port range options might require more than one CAM entry. The Layer 2 ACL CAM partition has sub-partitions for several types of information. Table 10-1, "Layer 2 ACL CAM Sub-partition Sizes," in IP Access Control Lists (ACL), Prefix Lists, and Route-maps lists the sub-partition and the percentage of the Layer 2 ACL CAM partition that FTOS allocates to each by default. Table 10-1. Layer 2 ACL CAM Sub-partition Sizes Partition Sysflow L2ACL *PVST QoS L2PT FRRP % Allocated 6 14 50 12 13 5 You can re-configure the amount of space, in percentage, allocated to each sub-partition. As with the IPv4Flow partition, you can configure the Layer 2 ACL partition from EXEC Privilege mode or CONFIGURATION mode. The amount of space that you can distribute to the sub-partitions is equal to the amount of CAM space that the selected CAM profile allocates to the Layer 2 ACL partition. FTOS requires that you specify the amount of CAM space for all sub-partitions and that the sum of all sub-partitions is 100%. FTOS displays the following message if the total allocated space is not correct: % Error: Sum of all regions does not total to 100%. IP Access Control Lists (ACL), Prefix Lists, and Route-maps | 133
