1.4 Port Security Configuration Example
1.4.1 Port Security Configuration Example
I. Network requirements
Implement access user restrictions through the following configuration on Ethernet
1/0/1 of the switch.
z 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.
z 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.
z 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.
