Important Points to Remember
• All line cards within a single system must have the same CAM profile; this profile must match the system CAM
profile (the profile on the primary RPM).
– FTOS automatically reconfigures the CAM profile on line cards and the secondary RPM to match the
system CAM profile by saving the correct profile on the card and then rebooting it.
• The CAM configuration is applied to entire system when you use the CONFIGURATION mode commands. Save
the running-configuration to affect the change.
• All CAM configuration commands require you to reboot the system.
• 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. Refer to Pre-Calculating Available QoS CAM Space.
• After you install a secondary RPM, copy the running-configuration to the startup-configuration so that the new
RPM has the correct CAM profile.
Select CAM Profiles
A CAM profile is selected in CONFIGURATION mode. The CAM profile is applied to entire system; however, you must
save the running-configuration to affect the change.
All components in the chassis must have the same CAM profile and microcode. The profile and microcode loaded on the
primary RPM determines the profile that is required on all other chassis components.
• If a newly installed line card has a profile different from the primary RPM, the card reboots so that it can load the
proper profile.
• If a the standby RPM has a profile different from the primary RPM, the card reboots so that it can load the proper
profile.

CAM Allocation
The user configurable CAM allocations feature is available on the Z9000 platform.
The CAM space is allotted in filter processor (FP) blocks. The total space allocated must equal 13 FP blocks.
NOTE: There are 16 FP blocks, but the system flow requires three blocks that cannot be reallocated.
The following table lists the default CAM allocation settings.
