The cam table will essentially resolve local port to other side mac address. The switch receives this frame and checks its MAC table for the cc-cc-cc-cc-cc-cc address. Hence it does not need to look in ARP cache. B. However, MAC refers to the contents, and CAM the type of memory. with default timers this means that that MAC address has been silent for more then 300 seconds (CAM aging time) and less then for 4 hours (ARP timeout), it is not a problem itself it can be an effect and not a cause. z. From my understanding CAM is the Content−Addressable Memory which is available per port on the switch to speed up ethernet ID lookup. The mac address or CAM table shows the Vlan associated with the port, MAC being learned on the port (i. The fact that the table comes up empty is very probably correct. + = Permanent Entry. D .
