MAC address table configuration example
Network requirements
The MAC address of Host A, which is connected to GigabitEthernet 0/1 of the device and belongs to
VLAN 1, is 000f-e235-dc71. The MAC address of Host B, which belongs to VLAN 1, is 000f-e235-abcd.
To prevent MAC address spoofing, add a static entry into the MAC address table of the device for Host
A.
Because Host B once behaved suspiciously on the network, you can add a destination blackhole MAC
address entry for the MAC address to drop all packets destined for the host for the sake of security.
Set the aging time for dynamic MAC address entries to 500 seconds.

Configuring LB
Before making the following configurations, check whether GigabitEthernet 0/1 operates in router mode.
If yes, change its operating mode to bridge mode. To do that, select System > Interface from the
navigation tree, and then find and select GigabitEthernet 0/1 to configure it accordingly.
1. Create a static MAC address entry:
a. Select Network > MAC from the navigation tree.
b. Click Add.
