Re-allocating CAM for Ingress ACLs and QoS
The default CAM allocation settings for ingress ACL and QoS regions are:
• L2 ACL(l2acl): 4
• L3 ACL (ipv4acl): 4
• IPv6 L3 ACL (ipv6acl): 0
• L3 QoS (ipv4qos): 2
• L2 QoS (l2qos): 1
• L2PT (l2pt): 0
• MAC ACLs (ipmacacl): 0
• ECFMACL (ecfmacl): 0
• VMAN QoS (vman-qos): 0
• VMAN Dual QoS (vman-dual-qos): 0
• FCoE ACL (fcoeacl): 2
• iSCSI Opt ACL (iscsioptacl): 0
The
ipv6acl and vman-dual-qos allocations must be entered as a factor of 2 (2, 4, 6, 8, 10). All other CAM
regions can use either even or odd numbered numbers.
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:
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.

Enter a CAM allocation action to perform
on ingress ACLs.

CONFIGURATION
Note: Selecting default resets the CAM entries to the default settings. Select l2acl to re-allocate memory space
for ingress ACL and QoS regions.
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.
