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 4/0/1 of the router. To prevent MAC address spoofing, add a static entry into the
MAC address table of the router for the host.
• The MAC address of Host B 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.
