TCAM:
1. A special type of memory for high-speed lookups.
2. Dedicated to packet classification and forwarding.
3. Stores complex forwarding information, such as Layer 2/Layer 3 forwarding, ACLs, and QoS.
4. Three possible results: true (0), false (1), and don’t care (X).
5. High speed and flexibility, suitable for complex packet processing.
MAC Address Table:
1. A data structure that stores MAC addresses and their port information.
2. Typically implemented using RAM.
3. Stores MAC addresses and their associated ports for Layer 2 forwarding.
4. Two results: true (0) and false (1).
5. Slower speed and less flexibility.
TCAM (Ternary Content-Addressable Memory) is a specialised type of memory used in network devices for high-speed table lookups. It stores information related to forwarding decisions, including Layer 2 and Layer 3 forwarding information.
The MAC address table, however, is a logical data structure used by switches to store MAC addresses and their associated port information. It's typically implemented using RAM (Random Access Memory) within the switch's hardware.
Mac address-table is populated as traffic ingresses into the port from hosts. Not sure the 2nd part of the answer in A is quite right. It seems to suggest that the only way to populate it would be with a static entry.
