F3215-HP Load Balancing Module Network Management Configuration Guide-6PW101

MAC address table configuration example

Network requirements

As shown in Figure 20:

• The MAC address of Host A is 000f-e235-dc71 and belongs to VLAN 1. It is connected to

GigabitEthernet 0/1 of the device. To prevent MAC address spoofing, add a static entry for the host

in the MAC address table of the device.

• The MAC address of Host B is 000f-e235-abcd and belongs to VLAN 1. For security, because this

host once behaved suspiciously on the network, add a destination blackhole MAC address entry for

the host MAC address, so all packets destined for the host are dropped.

• Set the aging timer for dynamic MAC address entries to 500 seconds.
