Follow these steps to disable the current port from learning MAC addresses:
Enter system view
Enter Ethernet port view
Disable the current port
from learning MAC
addresses
Note:
Do not use the mac-address mac-learning disable command together with
related 802.1x commands in Ethernet port view.
Do not use the mac-address mac-learning disable command together with the
mac-address max-mac-count command.
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.
Follow these steps to configure MAC address learning synchronization between board
chips:
