Dell C1048P Port Extender Networking Configuration Guide for the C9000 Series - Page 129

The CAM space is allotted in filter processor (FP) blocks. The total amount of space allowed is 12 FP Blocks. System flow requires four blocks; these blocks cannot be reallocated. The ipv4acl profile range is from 0 to 8. When configuring space foripv6acl, the total number of Blocks must equal 12. The ipv6acl allocation must be a factor of 2 (2, 4). If allocation values are not entered for the CAM regions, the value is 0. Save the new CAM settings to the startup-config (use write-mem or copy run start) then reload the system for the new settings to take effect. Test CAM Usage The test cam-usage command is supported on the C9000 series. This command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS optimization for IPv6 ACLs. To determine whether sufficient ACL CAM space is available to enable a service-policy, use this command. To verify the actual CAM space required, create a class map with all the required ACL rules, then run the test cam-usage command in EXEC and EXEC Privilege mode. The following example shows the output when running this command. The status column indicates whether you can enable the policy. • test cam-usage service-policy input policy-map-input-name {{linecard line-card-number port-set port-set} | {linecard all [port-set port-set]} | { pe pe-id stack-unit stack-unit-number port-set port-set}} Parameters • line card - Enter the linecard keyword and one of the following options: • linecard number (from 0 to 11) and then the port-set keyword and number. • All to specify all line card numbers and then the port-set keyword and number. • stack-unit stack-unit-number - Enter the keyword stack-unit and then the stack unit number. The range is 0-7. • pe pe-id - Enter the keyword pe and then the port-extender ID. The range is from 0 to 255 • port-set port-set - Enter the port-set keyword and then a port pipe/number. This is optional parameter with the linecard all option. • policy-input map policy-map-input-name - Enter the input policy map name (maximum of 32 characters).
