Port security configuration examples
Basic port security mode configuration example
Network requirements
As shown in Figure 418, configure port GigabitEthernet 1/0/3 of the switch as follows:
• Allow up to three users to access the port without authentication, and permit the port to learn the
MAC addresses of the users as secure MAC addresses.
• After the number of secure MAC addresses reaches 3, the port stops learning MAC addresses. If an
unknown MAC address frame arrives, intrusion protection is triggered and the port is disabled and
stays silence for 30 seconds.
