Content Addressable Memory (CAM)
CAM is a type of memory that stores information in the form of a lookup table.
On the switch, CAM stores Layer 2 and Layer 3 forwarding information, access-lists (ACLs), ows, and routing policies. On a line card,
there are one or two CAM (Dual-CAM) modules per port-pipe.

CAM Allocation
CAM space is allotted in lter processor (FP) blocks. The total space allocated must equal 12 FP blocks.
NOTE
: There are 16 FP blocks, but the system ow requires three blocks that cannot be
reallocated.
The following table displays the default CAM allocation settings. To display the default CAM allocation, enter the show cam-acl
command.
