Thank you, the concepts are clearer now but those websites said that TCAMs are better for ACLs, QoS and Routing table (either for routers or layer 3 switches) and when the switch looks for a MAC address, the CAM is good for that job, but the CCNA book says that MACs are looked up in TCAM when ASIC is making forwarding. Cisco uses the terms MAC address table and CAM table interchangeably. The Adjacency table records IP address and Layer 2 header for the IP and then references the TCAM table and at this point the switch will have enough information to rewrite the packets headers and send them out the egress port. In your case, With CAM table full, you introduced a new PC, all the traffic to the new PC will be broadcast to all the ports in that VLAN, till any of the entry times out and. When that occurs, the switch floods all ports with incoming traffic because it cannot find the port number for a particular MAC address in the CAM table. 9 inches, but the iPad Pro's screen is superior in pretty much every other way. switch# show mac address-table.
