Content Addressable Memory (CAM) | 263The amount of space that you can distribute to the sub-partitions is equal to the amount of CAM space thatthe selected CAM profile allocates to the Layer 2 ACL partition. FTOS requires that you specify theamount of CAM space for all sub-partitions and that the sum of all sub-partitions is 100%. FTOS displaysthe following message if the total allocated space is not correct:% Error: Sum of all regions does not total to 100%.Boot BehaviorThe profile and microcode loaded on the primary RPM determines the profile and microcode that isrequired on all other chassis components and is called the “chassis profile.” A profile mismatch conditionexists if either the CAM profile or the microcode does not match. The following points describe line cardboot 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), buttheir CAM profiles do not match, the line card must load a new profile and therefore takes longer tocome online.• If you insert a single-CAM line card into a chassis with a dual-CAM profile, the system displaysMessage 1. The line card boots with the default (single-CAM) profile and remains in a problem stateas shown in the following command output example. The line card cannot forward traffic in a problemstate.• If you insert a dual-CAM line card into a chassis with a single-CAM profile, the line card boots with amatching profile, but operates with a lower capability.Example: EF Line Card with EG Chassis Profile (CardProblem)R1#show linecard 1 briefMessage 1 EF Line Card with EG Chassis Profile Error# Before reload:01:09:56: %RPM0-P:CP %CHMGR-4-EG_PROFILE_WARN: If EG CAM profile is selected, non-EGcards will be in problem state after reload# After reload:00:04:46: %RPM0-P:CP %CHMGR-3-PROFILE_MISMATCH: Mismatch: line card 1 has mismatch CAMprofile or microcodeMessage 2 EH Line Card with EG Chassis Profile Error# Before reload:01:09:56: %RPM0-P:CP %CHMGR-4-EH_PROFILE_WARN: If EH CAM profile is selected, non-EJcards will be in problem state after reload# After reload:00:04:46: %RPM0-P:CP %CHMGR-3-PROFILE_MISMATCH: Mismatch: line card 1 has mismatch CAMprofile or microcode
