BPDU guard enabled port when the port receives a BPDU. Then, the device starts the detection timer. If
the port is still down when the detection timer expires, the port quits the shutdown status and resume its
actual physical status.

(available only on the A3100 v2 EI)
You can set the temperature alarm thresholds to monitor the temperature of a device.

When the device temperature reaches the alarming threshold, the device constantly outputs log and tap
messages to the configuration terminal and lights the temperature alarm LED on the device panel.
