Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Default level
2: System level
Parameters
dynamic: Specifies dynamic MAC address entries. These entries can age.
static: Specifies static MAC address entries. They do not age, but you can add or remove them.
mac-address: Specifies a MAC address in the format of H-H-H, where 0s at the beginning of each H (16 -
bit hexadecimal digit) can be omitted. For example, inputting ―f-e2-1‖ indicates that the MAC address is
―000f-00e2-0001‖.
vlan vlan-id: Specifies an existing VLAN to which the Ethernet interface belongs, where vlan-id is the
specified VLAN ID, in the range of 1 to 4094.
Examples
# Add a static entry for MAC address 000f-e201-0101 on port GigabitEthernet 1/0/1 that belongs to
VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] mac-address static 000f-e201-0101 vlan 2
# Add a static entry for MAC address 000f-e201-0102 on port Bridge-Aggregation 1 that belongs to
VLAN 1.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] mac-address static 000f-e201-0102 vlan 1
mac-address (system view)
Description
Use the mac-address command to add or modify a MAC address entry.
Use the undo mac-address command to remove one or all MAC address entries.
A static or blackhole MAC address entry will not be overwritten by a dynamic MAC address entry. A
dynamic MAC address entry can be overwritten by a static or blackhole MAC address entry.
If you execute the undo mac-address command without specifying any parameters, this command deletes
all unicast MAC address entries and static multicast MAC address entries.
You can delete all the MAC address entries (including unicast MAC address entries and static multicast
MAC address entries) of a VLAN, or you can choose to delete a specific type (dynamic, static, or
blackhole) of MAC address entries only. You can single out certain ports and delete the corresponding
unicast MAC address entries, but not the corresponding static multicast MAC address entries.
The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC
address table entries, however, are lost at next reboot regardless of whether you save the configuration or
not.
