You can configure a multiport unicast MAC address entry globally or on an interface.
Configuring a multiport unicast MAC address entry globally
1. Enter system view.
system-view
2. Add or modify a multiport unicast MAC address entry.
mac-address multiport mac-address interface interface-list vlan
vlan-id
By default, no multiport unicast MAC address entry is configured globally.
Make sure you have assigned the interface to the VLAN.
Configuring a multiport unicast MAC address entry on an interface
1. Enter system view.
system-view
2. Enter interface view.
{ Enter Layer 2 Ethernet interface view.
interface interface-type interface-number
{ Enter Layer 2 aggregate interface view.
interface bridge-aggregation interface-number
3. Add the interface to a multiport unicast MAC address entry.
mac-address multiport mac-address vlan vlan-id
By default, no multiport unicast MAC address entry is configured on an interface.

Setting the aging timer for dynamic MAC address
entries
About aging timer for dynamic MAC address entries
For security and efficient use of table space, the MAC address table uses an aging timer for each
dynamic MAC address entry. If a dynamic MAC address entry is not updated before the aging timer
expires, the device deletes the entry. This aging mechanism ensures that the MAC address table can
promptly update to accommodate latest network topology changes.
A stable network requires a longer aging interval, and an unstable network requires a shorter aging
interval.
