MAC address table configuration example

Network requirements

As shown in
The MAC address of Host A 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 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 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.
