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.

• The ExaScale EH and EJ series line cards are single-CAM line cards that support 10M and 40M CAM

for storing the lookup information.
