Configuring MAC Address Limiting

Configuring MAC Address Limiting

Run the mac-address limit maximum max-num command in the interface or VLAN view to limit the number of MAC address entries learned on the interface or in the VLAN. By default, the number of learned MAC address entries is not limited. max-num ranges from 0 to 32767. The value 0 indicates that the number of learned MAC address entries is not limited.

# Set the maximum number of MAC address entries learned by 10GE1/0/1 to 30.
<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] mac-address limit maximum 30
[*HUAWEI-10GE1/0/1] commit
# Set the maximum number of MAC address entries learned in VLAN 10 to 20.
<HUAWEI> system-view
[~HUAWEI] vlan 10
[*HUAWEI-vlan10] mac-address limit maximum 20
[*HUAWEI-vlan10] commit
NOTE:

For the CE8800&7800&6800&5800 series switches excluding the CE6870EI, CE6875EI, CE6880EI, and the CE12800E that has the FD-X series cards installed, after MAC address limiting is configured on an interface, the VXLAN packets received by the interface are not affected by this function.
