When using the mac-address command to add a MAC address entry, the interface specified by the 

interface keyword must belong to the VLAN specified by the vlan keyword, and the VLAN must already 

exist. Otherwise, you will fail to add this MAC address entry. 

 

Follow these steps to add, modify, or remove entries in the MAC address table on an interface: 

Enter system view

Enter Ethernet 
interface view 

interface interface-type 
interface-number 

Enter Layer 2 
aggregate 
interface view 

interface bridge-aggregation 
interface-number

Use any of the three 
commands. 

The configuration you make in 
Ethernet interface view or 
Layer 2 aggregate interface

When using the mac-address command to add a MAC address entry, the current interface must 

belong to the VLAN specified by the vlan keyword, and the VLAN must already exist. Otherwise, 

you will fail to add this MAC address entry.

When using the mac-address command to add a static MAC address for a VLAN, if this VLAN 

configured the Isolate-user-vlan function, you must add this static MAC address for the 

Isolate-user-vlan and the Secondary VLAN. 

 

You may need to disable MAC address learning sometimes to prevent the MAC address table from 

being saturated, for example, when your device is being attacked by a large amount of packets with 

different source MAC addresses. 

Disabling global MAC address learning disables the learning function on all ports. 

Follow these steps to disable MAC address learning:
