MAC address table configuration example

Network requirements
The MAC address of one host is 000f-e235-dc71 and belongs to VLAN 1. It is connected to
•
GigabitEthernet 1/0/1 of the device. To prevent MAC address spoofing, add a static entry into the
MAC address table of the device for the host.
The MAC address of another host is 000f-e235-abcd and belongs to VLAN 1. Because this host
•
once behaved suspiciously on the network, you can add a blackhole MAC address entry for the
MAC address to drop all packets destined for the host.
Set the aging timer for dynamic MAC address entries to 500 seconds.

Configuration procedure
# Add a static MAC address entry.
<Sysname> system-view
[Sysname] mac-address static 000f-e235-dc71 interface gigabitethernet 1/0/1 vlan 1
# Add a blackhole MAC address entry.
[Sysname] mac-address blackhole 000f-e235-abcd vlan 1
# Set the aging timer for dynamic MAC address entries to 500 seconds.
[Sysname] mac-address timer aging 500
# Display the MAC address entry for port GigabitEthernet 1/0/1.
[Sysname] display mac-address interface gigabitethernet 1/0/1
