Network requirements
Restrict port GigabitEthernet 1/0/1 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.
