Network requirements
See Figure 48. Configure port Ethernet 1/1 on the Device, as follows:
• Accept up to 64 users on the port without authentication.
• Permit the port to learn and add MAC addresses as sticky MAC addresses, and set the secure MAC
aging timer to 30 minutes.
• 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 starts, and the port shuts
down and stays silent for 30 seconds.
