Configuring the detection timer
Some protocols might shut down ports under specific circumstances. For example, MSTP shuts down a 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.
Follow these steps to configure the detection timer:

Configuring temperature alarm thresholds (available only on the A3100 v2 EI)
You can set the temperature alarm thresholds to monitor the temperature of a device.
The temperature alarm thresholds include lower temperature limit, warning temperature threshold, and temperature alarming threshold.
When the device temperature drops below the lower limit or reaches the warning threshold, the device logs the event and outputs a log message and a trap.
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.
Follow these steps to configure temperature alarm thresholds:
