What this means
The IEEE assigned the MA-L block 000B7A to L-3 Linkabit. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting 00:0B:7A, it is L-3 Linkabit hardware.
