• 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 : and
• 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.
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 configure the IPv4 and IPv6 ACLs and Qos regions on the entire system:
Test CAM Usage
The test cam-usage command is supported on platforms c e s
This command applies to both IPv4 and IPv6 CAM profiles, but is best used when verifying QoS
optimization for IPv6 ACLs.
Note: On the S4810 and 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.

Note: Selecting default resets the CAM entries to the default settings. Select l2acl to allocate space for
the ACLs, and QoS regions.
