The lldp tlv-enable legacy-tlv power-capability command configures LLDP packets sent by an AP to carry the supported power capability.
The undo lldp tlv-enable legacy-tlv power-capability command configures LLDP packets sent by an AP not to carry the supported power capability.
By default, the LLDP packets sent by an AP carry the supported power capability.
Usage Scenario
When the PoE power supply meets only the 802.3af standard, APs that require 802.3at or 802.3bt PoE power supply can automatically lower the power consumption by disabling the USB function, lowering the transmit power, and reducing MU-MIMO. In this manner, the basic Wi-Fi function is still available when the power supply is insufficient. When directly connected to a Huawei PoE switch, the AP can send its power capability to the switch through LLDP. If the total output power of the PoE switch exceeds the threshold, the switch adjusts the output power of the corresponding Ethernet port based on the power capability of the AP. This reduces the output power without affecting the basic functions of the AP.
