Parameters
high: Assigns high MAC learning priority.
low: Assigns low MAC learning priority.
Usage guidelines
The MAC address learning priority values can be high and low. An interface with high MAC address
learning priority can learn any MAC address. An interface with low MAC address learning priority can
learn only the MAC addresses that have not been learned by the high-priority interfaces.
The MAC learning priority mechanism can help defend your network against MAC address spoofing
attacks. You can assign an uplink interface high MAC learning priority and a downlink interface low
MAC learning priority to prevent the downlink interface from learning the MAC address of an upper
layer device (for example, the gateway).
Examples
# Assign high MAC learning priority to interface Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname- Ten-GigabitEthernet1/0/1] mac-address mac-learning priority high
# Assign high MAC learning priority to interface Bridge-Aggregation 1.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] mac-address mac-learning priority high
# Assign high MAC learning priority to interface S-Channel 1/0/1:10.
<Sysname> system-view
[Sysname] interface s-channel 1/0/1:10
[Sysname-S-Channel1/0/1:10] mac-address mac-learning priority high
