Configure port Ten-GigabitEthernet 1/0/1 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 MACaging timer to 30 minutes.• After the number of secure MAC addresses reaches 64, the port stops learning MAC addresses. Ifany frame with an unknown MAC address arrives, intrusion protection starts, and the port shutsdown and stays silent for 30 seconds.Figure 34 Network diagramConfiguration procedure# Enable port security. system-view[Device] port-security enable# Set the secure MAC aging timer to 30 minutes.[Device] port-security timer autolearn aging 30# Set port security's limit on the number of secure MAC addresses to 64 on port Ten-GigabitEthernet1/0/1.[Device] interface ten-gigabitethernet 1/0/1[Device-Ten-GigabitEthernet1/0/1] port-security max-mac-count 64# Set the port security mode to autoLearn.[Device-Ten-GigabitEthernet1/0/1] port-security port-mode autolearn# Configure the port to be silent for 30 seconds after the intrusion protection feature is triggered.[Device-Ten-GigabitEthernet1/0/1] port-security intrusion-mode disableport-temporarily[Device-Ten-GigabitEthernet1/0/1] quit[Device] port-security timer disableport 30InternetDeviceXGE1/0/1Host
