1.2.6 Configuring MAC Address Learning Synchronization Between Board
Chips
If there are multiple chips on a board, each chip can learn only the MAC addresses of
the data flow it handles. If a chip receives a packet whose MAC address entry is stored
in another chip, it broadcasts the packet.
You can configure MAC address learning synchronization between board chips to
synchronize MAC address entries between chips. This reduces broadcasting of
unknown packets, lowers switch processing load, and improves network utilization.

chips:
