Can anybody explain how these two are related? I understand that ASIC allow switches to forward packets at high-speed lookups based in hardware. CAMs have a list of mac to port mappings.

Hi Christopher,


Lets try to say it in simple words, CAM is simply implemented in ASICs, from a CCO document:


ASICs is responsible for the Ethernet MAC layer functions, address or network lookup in the content-addressable memory (CAM) table, and forwarding of the packet with its correct rewrite information to the Fabric Interface.
