What would cause telemetry logging to stop?

A new PoE+VoIP handset was added to an EX Series device. The handset is experiencing
connectivity issues. The EX Series device’s committed configuration includes the set poe interface
all telemetry command. You look at the telemetry log in the device to review power consumption
and you notice entries have not been occurring for days. What would cause telemetry logging to
stop?

    PoE Options

    When configuring PoE, you must enable the PoE interface in order for the port to provide power to a connected, powered device. In addition, you can configure the following PoE features:

    Port priority—Sets port priority. When it is not possible to maintain power to all connected ports, lower priority ports are powered off before higher priority ports. When a new device is connected on a higher-priority port, a lower priority port will be powered off automatically if available power is insufficient to power on the higher priority port. (For the ports with the same priority configuration, ports on the left are given higher priority than the ports on the right.)

    Maximum available wattage power available to a port—Sets the maximum amount of power that can be supplied to the port. The default wattage per port is 15.4 watts.

    PoE power consumption logging—Allows logging of per-port PoE power consumption. The telemetries section must be explicitly specified to enable logging. If left unspecified, telemetries is disabled by default. The default telemetry duration is 1 hour. The default telemetry interval is 5 minutes.

    PoE power management mode—Has two modes:

    Class—When a powered device is connected to a PoE port, the power allocated to it is equal to the maximum power for the class as defined by the IEEE standards.

    Static—When a powered device is connected to a PoE port, the power allocated to it is equal to the maximum power configured for the port.

    Reserve power—Reserves the specified amount of power for the gateway in case of a spike in PoE consumption. The default is 0.
