MAC address table configuration example

Network requirements

On a network:
•
Host A at MAC address 000f-e235-dc71 is connected to interface GigabitEthernet 1/0/1 of
Device and belongs to VLAN 1.
•
Host B at MAC address 000f-e235-abcd, which 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 Host B.
•
Set the aging timer to 500 seconds for dynamic MAC address entries.
