What is an effect of having multiple MAC addresses in a switch's MAC address table?

Having multiple MAC addresses in a switch's MAC address table enhances data flow management within a network. A switch learns and registers the source MAC addresses of incoming frames, allowing it to efficiently direct traffic to the specific ports where the destination devices are connected. This capability reduces unnecessary broadcasts and optimizes the overall network performance by ensuring that data packets are sent only to the intended recipient rather than to all devices on the network.

When a switch has a diverse set of MAC addresses in its table, it can quickly adapt to the various communications occurring on the network. This leads to better utilization of the switch’s resources and allows for more effective handling of concurrent data streams, which is particularly beneficial in environments with significant traffic loads, such as those involving audio, video, or large data transfers.

In summary, multiple MAC addresses in a switch's MAC address table contribute to improved data flow management by enhancing the switch's ability to direct traffic accurately and efficiently within the network.
