What command clears all dynamic MAC addresses on a specific interface from the MAC Address Table?

The command used to clear all dynamic MAC addresses on a specific interface from the MAC Address Table is correctly identified as "clear mac address-table dynamic interface interface-id." This command specifically targets the dynamic MAC addresses associated with a particular interface, allowing network administrators to manage the MAC address table effectively.

When using this command, "clear mac address-table" specifies the action to clear MAC addresses, while "dynamic" limits this action to only the dynamic entries in the MAC address table, which are learned MAC addresses as opposed to static mappings. By appending "interface interface-id," the command specifies the interface from which dynamic MAC addresses should be removed. This precision in targeting is crucial for maintaining performance and managing MAC address table size, especially in environments where devices frequently connect and disconnect.

The other options either do not exist in Cisco IOS or do not achieve the desired effect of clearing dynamic MAC addresses from a specific interface. For example, commands that mention general terms like "reset" or "remove" without the correct syntax do not provide the exact functionality needed to manage the MAC Address Table as intended. Thus, the appropriate syntax and structure of option A ensure accurate clearing of the required dynamic entries.
