What does a MAC address table in a virtual switch allow it to do?

A MAC address table in a virtual switch functions as a critical component that enhances the switch's capability to manage data frames effectively within a network. The primary role of the MAC address table is to maintain a mapping of MAC addresses to the corresponding ports on the switch. This allows the virtual switch to intelligently forward frames to the correct port based on the destination MAC address found in the Ethernet frames it processes.

When a frame arrives at the virtual switch, the switch examines the MAC address of the destination device. By referencing its MAC address table, the virtual switch can determine which port the frame should be sent out of to reach the appropriate device. This process minimizes unnecessary traffic on other ports, optimizing network performance and bandwidth usage.

The other options discuss functions that are not the primary purposes of the MAC address table. Identifying various logical interfaces involves understanding the architecture and configuration of the virtual switch rather than the MAC table's specific function. Filtering out unwanted traffic typically relates to firewall rules or access control lists rather than how MAC addresses are managed. Establishing virtual connections to remote networks pertains more to routing and connections between different network segments, which falls outside the direct role of the MAC address table in a switch's operation.
