Search Support for Layer 2 (Non-Routable) MAC Addresses

NetBrain search currently allows users to locate a MAC address only when it is associated with a Layer 3 interface; MAC addresses learned solely at Layer 2, such as entries found in a switch's MAC address table for non-routable segments, cannot be located through search. This enhancement proposes extending the search functionality to also query Layer 2 MAC address table data, so that a MAC address can be found regardless of whether it is tied to an L3 interface or exists only in an L2 forwarding table. This would allow customers to quickly locate the switch and port associated with a given MAC address without manually running CLI commands, improving troubleshooting efficiency in L2-only network segments.
