Reference Guide

Enter the ipv6acl and vman-dual-qos allocations as a factor of 2 (2, 4, 6, 8, 10). All other CAM regions
can use either even or odd numbered numbers.
NOTE: On the S5000, 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.
To reconfigure the memory regions on the S5000 used for ingress ACLs and QoS, follow these steps.
1. Enter a CAM allocation action to perform on ingress ACLs.
CONFIGURATION mode
cam-acl [default | l2acl]
NOTE: Selecting default resets the CAM entries to the default settings. To re-allocate memory
space for ingress ACL and QoS regions, select l2acl.
2. Enter the number of FP blocks for each region. Separate each keyword and number with a blank
space. The total CAM space allocated must equal 13.
EXEC Privilege mode
l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number l2pt
number ipmacacl number ecfmacl number {vman-qos number | vman-dual-qos
number} [fcoeacl number] [iscsioptacl number]
3. Verify the new settings that will be written to the CAM on the next reload.
EXEC Privilege mode
show cam-acl
4. Reload the system.
EXEC Privilege mode
reload
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.
