Parameters
dynamic
: Specifies dynamic MAC address entries.
static
: Specifies static MAC address entries.
multiport
: Specifies multiport unicast MAC address entries. A frame whose destination MAC
address matches a multiport unicast MAC address entry is sent out of multiple ports.
mac-address
: Specifies a MAC address in the format of H-H-H, excluding multicast, all-zero, and
all-F MAC addresses. When entering a MAC address, you can omit the leading zeros in each H
section. For example, enter f-e2-1 for 000f-00e2-0001.
vlan vlan
-
id
: Specifies an existing VLAN to which the specified interface belongs. The value
range for the
vlan-id
argument is 1 to 4094.
Usage guidelines
Typically, the device automatically builds the MAC address table by learning the source MAC
addresses of incoming frames on each interface. However, you can manually configure static MAC
address entries. For a MAC address, a manually configured static entry takes precedence over a
dynamically learned entry. To improve the security for the user device connected to an interface,
manually configure a static entry to bind the user device to the interface. Then, the frames destined
for the user device (for example, Host A) are always sent out of the interface. Other hosts using the
forged MAC address of Host A cannot obtain the frames destined for Host A.
The MAC address entry configuration cannot survive a reboot unless you save it. The dynamic MAC
address entries, however, are lost upon reboot whether or not you save the configuration.
Examples
# Add a static entry for MAC address 000f-e201-0101 on 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-e201-0101 on 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
# Add a multiport unicast MAC address entry for MAC address 0001-0001-0101 on GigabitEthernet
1/0/1 and GigabitEthernet 1/0/2 that belong to VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
