CAM Allocation Setting
VMAN QoS (vman-qos) 0
VMAN Dual QoS (vman-dual-qos) 0
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.
NOTE: There can be only one odd number of Blocks in the CLI configuration; the other Blocks must be in
factors of 2. For example, a CLI configuration of 5+4+2+1+1 Blocks is not supported; a configuration of
6+4+2+1 Blocks is supported.
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.
1 Select a cam-acl action.
CONFIGURATION mode
cam-acl [default | l2acl]
NOTE: Selecting default resets the CAM entries to the default settings. Select l2acl to allocate
space for the ACLs and QoS regions.
2 Enter the number of FP blocks for each region.
EXEC Privilege mode
l2acl number ipv4acl number ipv6acl number, ipv4qos number l2qos number, l2pt
number ipmacacl number ecfmacl number nlbcluster number[vman-qos | vman-dual-
qos number
3 Reload the system.
EXEC Privilege mode
reload
4 Verify that the new settings will be written to the CAM on the next boot.
EXEC Privilege mode
show cam-acl
Test CAM Usage
This command applies to both IPv4 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. The Status column in the command output indicates whether
or not the policy can be enabled.
Example of the test cam-usage Command
Dell#test cam-usage service-policy input pmap stack-unit all
