The
ipv6acl
and
vman-dual-qos
allocations must be entered as a factor of 2 (2, 4, 6, 8, 10). All other profile
allocations can use either even or odd numbered ranges.
You must save the new CAM settings to the startup-config (
write-mem or copy run start
) then reload the
system for the new settings to take effect.
To configure the IPv4 and IPv6 ACLs and Qos regions on the entire system:
Test CAM Usage
The
test cam-usage
command is supported on platforms
c e s
This command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS
optimization for IPv6 ACLs.
Use this command to determine whether sufficient ACL CAM space is available to enable a service-policy.
Create a Class Map with all required ACL rules, then execute the
test cam-usage
command in Privilege
mode to verify the actual CAM space required. Figure 11-3 gives a sample of the output shown when
executing the command. The status column indicates whether or not the policy can be enabled.
