Re-Allocating CAM for Egress ACLs
The default CAM allocation settings for the three egress ACL and QoS regions on an S5000 switch include the following.
• L2 ACL(l2acl): 1
• L3 ACL (ipv4acl): 1
• IPv6 L3 ACL (ipv6acl): 2
The total egress CAM ACL space must equal four memory blocks. The ranges of supported FP memory blocks are:
• L2 ACL(l2acl): from 1 to 4
• L3 ACL (ipv4acl): from 1 to 4
• IPv6 L3 ACL (ipv6acl): from 0 to 4
You must allocate at least one block of memory to the L2ACL and IPv4 ACL regions.
You must save the new CAM settings to the startup-cong (write-mem or copy run start) then reload the system for the
new settings to take eect.
To recongure the memory regions on the S5000 used for egress ACLs and QoS, follow these steps.
1. Enter the number of FP blocks for each egress ACL region. Separate each keyword and number with a blank space.

Testing CAM Usage for QoS Policies
The test cam-usage command applies to the IPv4 ingress CAM partition.
To determine whether there is sucient space in this CAM region for the ACLs created in QoS service-policies, use this command.
