What is Switch MAC Table (CAM Table)? 2. show (mac-address-table) Displays addresses in the MAC address table for a switched port or module. If both hosts are transmitting constantly, that will cause the MAC address entry to bounce between the two switch ports (known as MAC flapping ). The router has a single table (CAM - content addressable memory) where it stores things like MAC address associations. Let’s turn this into a static entry: SW1(config)#mac address-table static 001d. For example, if you have 1000 devices connected. Content Addressable Memory (CAM) All Catalyst switch models use a Content Addressable Memory (CAM) table for Layer 2 switching. The MAC address table is a way to map each and every port to a MAC address. CAM - Content Addressable Memory, referring to the memory used for the MAC address table. What is a CAM Table Overflow Attack? A CAM table overflow attack is a hostile act performed against a network switch in which a flood of bogus MAC addresses is sent to the switch.

NX-OS: Default mac-address timeout: 30 min (1800 secs) Default arp timeout: 25 min (1500 secs) with the following note: The ARP timeout should be less than the MAC address table aging timer, so the ARP updates prevent entries from timing out of the MAC address table. 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. An Ethernet switch in a switched network contains a CAM table that holds all of the MAC addresses of devices in the network. You examine this on your layer 3 device.
