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 Ethernet
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.
