User-Configurable CAM Allocation
User-configurable content-addressable memory (CAM) allows you to specify the amount of memory
space that you want to allocate for ACLs.
To allocate ACL CAM, use the cam-acl command in CONFIGURATION mode. For information about
how to allocate CAM for ACL VLANs, see
Allocating ACL VLAN CAM.
The CAM space is allotted in filter processor (FP) blocks. The total amount of space allowed is 12 FP
Blocks. System flow requires four blocks; these blocks cannot be reallocated.
The ipv4acl profile range is from 0 to 8. When configuring space foripv6acl, the total number of
Blocks must equal 12. The ipv6acl allocation must be a factor of 2 (2, 4). If allocation values are not
entered for the CAM regions, the value is 0.
Save the new CAM settings to the startup-config (use write-mem or copy run start) then reload the
system for the new settings to take effect.
Allocating CAM for Ingress ACLs on the Port Extender
To allocate Content Addressable Memory (CAM) for ingress ACLs on the port extenders.
You can re-allocate memory space for ACLs on the port extender by using the cam-acl-pe l2acl
command in CONFIGURATION mode. CAM space is allotted in FP blocks. The total allocated CAM space
must equal 12 FP blocks. Note that there are 16 FP blocks, but the System Flow requires 4 blocks that
cannot be reallocated.
