MAC address table configuration example

Network requirements

On a network:
Host A at MAC address 000f-e235-dc71 is connected to interface Ten-GigabitEthernet 1/1/5 of
•
Device and belongs to VLAN 1.
Host B at MAC address 000f-e235-abcd), which once behaved suspiciously on the network, also
•
belongs to VLAN 1.
Configure the MAC address table as follows:
To prevent MAC address spoofing, add a static entry for Host A in the MAC address table of
•
Device.
To drop all frames destined for Host B, add a blackhole MAC address entry for the host.
•
Set the aging timer for dynamic MAC address entries to 500 seconds.
•

Configuration procedure

# Add a static MAC address entry for MAC address 000f-e235-dc71 on Ten-GigabitEthernet 1/1/5 that
belongs to VLAN 1.
