CAM Allocation

Allocate space for IPV4 ACLs and quality of service (QoS) regions by using the cam-acl command in CONFIGURATION mode.

The CAM space is allotted in filter processor (FP) blocks. The total space allocated must equal 13 FP blocks.

NOTE: There are 16 FP blocks, but the system flow requires three blocks that cannot be reallocated.

The following table lists the default CAM allocation settings.

Table 1. Default Cam Allocation Settings
CAM Allocation	Setting
L3 ACL (ipv4acl)	2
L2 ACL(l2acl)	2
IPv6 L3 ACL (ipv6acl)	0
L3 QoS (ipv4qos)	2
L2 QoS (l2qos)	0
L2PT (l2pt)	0
MAC ACLs (ipmacacl)	0
ECFMACL (ecfmacl)	0
nlbclusteracl	2
FCOEACL (fcoeacl)	4
ISCSIOPTACL (iscsioptacl)	2
VMAN QoS (vman-qos)	0
VMAN Dual QoS (vman-dual-qos)	0

The ipv6acl and vman-dual-qos allocations must be entered as a factor of 2 (2, 4, 6, 8, 10). All other profile allocations can use either even or odd numbered ranges.

NOTE: 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.

Select a cam-acl action. CONFIGURATION mode cam-acl [default | l2acl]
- NOTE: Selecting default resets the CAM entries to the default settings. Select l2acl to allocate space for the ACLs and QoS regions.
Enter the number of FP blocks for each region. EXEC Privilege mode l2acl number ipv4acl number ipv6acl number, ipv4qos number l2qos number, l2pt number ipmacacl number ecfmacl number nlbcluster number[vman-qos | vman-dual-qos number
Reload the system. EXEC Privilege mode reload
Verify that the new settings will be written to the CAM on the next boot. EXEC Privilege mode show cam-acl
