If a chip receives a packet whose MAC address entry is storedin another chip, it broadcasts the packet.You can configure MAC address learning synchronization between board chips tosynchronize MAC address entries between chips. This reduces broadcasting ofunknown packets, lowers switch processing load, and improves network utilization.Follow these steps to configure MAC address learning synchronization between boardchips:To do… Use the command… RemarksEnter system view system-view —Enable MAC addresslearning synchronizationbetween board chipsmac-addresslearningsynchronizationOptionalBy default, MAC addresslearning synchronizationbetween board chips isdisabled.
