What component of a virtual switch plays a crucial role in mapping devices?

The MAC Address Table is essential for mapping devices on a virtual switch because it stores the MAC addresses of devices connected to each port of the switch. This table allows the switch to send packets to the correct destination by associating each device with the specific port it is connected to. When a frame arrives at the virtual switch, it checks the source MAC address and the corresponding port, updating its MAC Address Table. When the virtual switch needs to forward a frame, it consults this table to determine where to send the frame based on the destination MAC address.

In contrast, the Routing Table focuses on determining paths for network traffic over various routes and is more relevant for routers rather than switches. The Access Control List is used for defining rules that permit or deny traffic but does not play a direct role in device mapping. The DHCP Lease Table relates to the management of IP addresses assigned to devices in a network rather than mapping hardware addresses like the MAC Address Table. Thus, the MAC Address Table is the most critical component for understanding how devices are mapped and identified on a virtual switch.
