Port Security Configuration Examples

Configuring the autoLearn Mode

Network requirements
Restrict port GigabitEthernet 2/0/1 of the switch as follows:
Allow up to 64 users to access the port without authentication and permit the port to learn and add
the MAC addresses of the users as secure MAC addresses.
After the number of secure MAC addresses reaches 64, the port stops learning MAC addresses. If
any frame with an unknown MAC address arrives, intrusion protection is triggered and the port is
disabled and stays silence for 30 seconds.
