Page 223 highlights
The Layer 2 ACL CAM partition has sub-partitions for several types of information. Table 10-4 lists the sub-partition and the percentage of the Layer 2 ACL CAM partition that FTOS allocates to each by default. Table 10-4. Layer 2 ACL CAM Sub-partition Sizes Partition % Allocated Sysflow 6 L2ACL 14 *PVST 50 QoS 12 L2PT 13 FRRP 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%. Boot Behavior The profile and microcode loaded on the primary RPM determines the profile and microcode that is required on all other chassis components and is called the "chassis profile." A profile mismatch condition exists if either the CAM profile or the microcode does not match. The following points describe line card boot behavior when the line card profile does not match the chassis profile. • A microcode mismatch constitutes a profile mismatch. • When the line card profile and chassis profile are of the same type (single-CAM or dual-CAM), but their CAM profiles do not match, the line card must load a new profile and therefore takes longer to come online. • If you insert a single-CAM line card into a chassis with a dual-CAM profile, the system displays Message 1. The line card boots with the default (single-CAM) profile and remains in a problem state (Figure 10-1). The line card cannot forward traffic in a problem state. Content Addressable Memory | 223
