Views
Ethernet interface view, aggregate interface view, S-channel interface view
Predefined user roles
network-admin
Parameters
dynamic: Specifies dynamic MAC address entries.
static: Specifies static MAC address entries.
mac-address: Specifies a MAC address in the format of H-H-H. 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
Generally, the device automatically builds the MAC address table by learning the source MAC
addresses of incoming frames on each interface. To improve the security for an interface, you can
manually add the specific MAC address entries to the MAC address table and bind the user device to the
interface. Because manually configured static entries have higher priority than dynamically learned
entries, using manually configured entries prevents hackers from using forged MAC addresses to steal
data.
The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC
address entries, however, are lost upon reboot regardless of whether you save the configuration.
Examples
# Add a static entry for MAC address 000f-e201-0101 on interface Ten-GigabitEthernet 1/0/1 that
belongs to VLAN 2.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] mac-address static 000f-e201-0101 vlan 2
# Add a static entry for MAC address 000f-e201-0102 on an aggregate interface 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 static entry for MAC address 000f-e201-0102 on interface S-Channel 1/0/1:10 that belongs to
VLAN 1.
<Sysname> system-view
[Sysname] interface s-channel 1/0/1:10
[Sysname- S-Channel1/0/1:10] mac-address static 000f-e201-0102 vlan 1
