Content Addressable Memory
Content Addressable Memory (CAM) is a type of memory that stores information in the form of a lookup
table. On Dell Force10 systems, the CAM stores Layer 2 and Layer 3 forwarding information, access-lists
(ACL), flows, and routing policies. On Dell Force10 systems, there are one or two CAM (Dual-CAM)
modules per port-pipe depending on the type of line card.
