MAC address table configuration example
Network requirements
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 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 to 500 seconds for dynamic MAC address entries.
Configuration procedure
# Add a static MAC address entry for MAC address 000f-e235-dc71 on GigabitEthernet 1/0/1 that
belongs to VLAN 1.
