• All line cards within a single system must have the same CAM profile (including CAM sub-region
configurations); 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 CONFIGURATION mode
commands. You must save the running-configuration to affect the change.
• 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.
• After you install a secondary RPM, copy the running-configuration to the startup-configuration so
that the new RPM has the correct CAM profile.
• You MUST save your changes and reboot the system for CAM profiling or allocations to take
effect.
The CAM Profiling commands are:
• cam-acl (Configuration)
• cam-acl (EXEC Privilege)
• cam-optimization
• cam-profile (Config)
• show cam-acl
• show cam-profile
• show cam-usage
• test cam-usage

Use the default CAM profile settings, and set the CAM as follows.
L3 ACL (ipv4acl): 6
L2 ACL(l2acl): 5
IPv6 L3 ACL (ipv6acl): 0
L3 QoS (ipv4qos): 1
L2 QoS (l2qos): 1

vman-qos | vman-dual-qos number
Allocate space to each CAM region.
Enter the CAM profile name followed by the amount to be allotted.
The total space allocated must equal 13.
The
ipv6acl range must be a factor of 2.
