Collaboration between Smart Link and Monitor Link for port status detection

Smart Link cannot detect when faults occur on the uplink of the upstream devices or when faults are cleared. You can configure the Monitor Link function to monitor the status of the uplink ports of the upstream devices. Monitor Link adapts the up/down state of downlink ports to uplink ports, and triggers Smart Link to perform link switchover on the downstream device. For more information about Monitor Link, see "Configuring Monitor Link."
