When configured for advertisement, this TLV advertises a request to the connected PD to go into a certain power conservation level or go to the maximum conservation level. This LLDP TLV is sent out only on PoE-capable Ethernet ports.
By default, the requested conservation value on this proprietary LLDP TLV is 0, which is no power conservation. You can change this level temporarily using a network station or SNMP with the MIB; this change is not saved across a reboot.
