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 11-1). The line card cannot forward traffic in a problem state.
• If you insert a dual-CAM line card into a chassis with a single-CAM profile, the line card boots with a 
matching profile, but operates with a lower capability.
