Reference Guide

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 11. Default Cam Allocation Settings
CAM Allocation Setting
L3 ACL (ipv4acl) 6
L2 ACL(l2acl) 5
IPv6 L3 ACL (ipv6acl) 0
L3 QoS (ipv4qos) 1
L2 QoS (l2qos) 1
L2PT (l2pt) 1
MAC ACLs (ipmacacl) 2
ECFMACL (ecfmacl) 0
VMAN QoS (vman-qos) 0
VMAN Dual QoS (vman-dual-qos) 0
The following additional CAM allocation settings are supported on the S4810 or S4820T platforms only.
Table 12. Additional Default CAM Allocation Settings
Additional CAM Allocation Setting
FCoE ACL (fcoeacl) 0
ISCSI Opt ACL (iscsioptacl) 2
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: On the S4820T, 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.
1. 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.
2. 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 [vman-qos | vman-dual-qos number
NOTE: If the allocation values are not entered for the CAM regions, the value is 0.
