Port Security Configuration Example
Network requirements
Implement access user restrictions through the following configuration on GigabitEthernet 1/0/1 of the
switch.
Allow a maximum of 80 users to access the port without authentication and permit the port to learn
and add the MAC addresses of the users as security MAC addresses.
To ensure that Host can access the network, add the MAC address 0001-0002-0003 of Host as a
security MAC address to the port in VLAN 1.
After the number of security MAC addresses reaches 80, the port stops learning MAC addresses. If
any frame with an unknown MAC address arrives, intrusion protection is triggered and the port will
be disabled and stay silent for 30 seconds.
