• iSCSI Opt ACL (iscsioptacl): 0
Enter the ipv6acl allocation as a factor of 2 (2, 4, 6, 8, 10). All other prole allocations can use either even-numbered or odd-numbered
ranges.
Save the new CAM settings to the startup-cong (use write-mem or copy run start) then reload the system for the new settings
to take eect.
For more information, refer to Re-allocating CAM for Ingress ACLs and QoS.
CAM Optimization
When you enable this command, if a policy map containing classication rules (ACL and/or dscp/ ip-precedence rules) is applied to more
than one physical interface on the same port-pipe, only a single copy of the policy is written (only one FP entry is used).
When you disable this command, the system behaves as described in this chapter.
Test CAM Usage
The test cam-usage command is supported on the S5000 platforms.
This command applies to both IPv4 and IPv6 CAM proles, but is best used when verifying QoS optimization for IPv6 ACLs.
To determine whether sucient 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 execute the test cam-usage command in Privilege mode. The
following example shows the output when executing this command. The status column indicates whether you can enable the policy.
Example of the test cam-usage Command

The show cam-acl command shows the cam-acl setting that will be loaded after the next reload.
