cam-acl (Configuration)
Select the default CAM allocation settings or reconfigure new CAM allocation for Layer 2, IPv4 and
IPv6 ACLs, Layer 2 and Layer 3 (IPv4) QoS, Layer 2 Protocol Tunneling (L2PT), IP and MAC source
address validation for DHCP, Ethernet Connectivity Fault Management (CFM) ACLs, and
Policy-based Routing (PBR).

Information
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.
The total amount of space allowed is 16 FP Blocks. System flow requires three blocks and these cannot
be reallocated. The ipv4acl profile range is 1-4.
When configuring space for IPv6 ACLs, the total number of Blocks must equal 13.
On the MXL 10/40GbE Switch IO Module, there can be only one odd number of Blocks in the CLI
configuration; the other Blocks must be in factors of two. 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.
Ranges for the CAM profiles are 1-10, except for the ipv6acl profile which is 0-10. The ipv6acl
allocation must be a factor of two (2, 4, 6, 8, 10).
default
Use the default CAM profile settings, and set the CAM as follows.
• L3 ACL (ipv4acl): 2
• L2 ACL(l2acl): 2
• IPv6 L3 ACL(ipv6Acl):0
• L3 QoS (ipv4qos): 2
• L2 QOS(L2Qos): 1
• L2PT (L2PT): 0
• MAC ACL (IpMacAcl): 0
• VmanDualQos: 0
• EcfmAcl: 0
• FcoeAcl: 4
• iscsiOptAcl: 2

Enter the CAM profile name followed by the amount of CAM
space to be allotted.
The total space allocated must equal 13.
The range for
ipv4acl is 1 to 4.
The
ipv6acl range must be a factor of 2.
The
