(Optional) Configuring the LLDP Power Capacity Negotiation
Context
You can configure the TLV in LLDP so that the device can classify PDs through the LLDP function enabled on the device. The device that is not configured with the LLDP function detects and classifies PDs through analyzing current and resistance between the device and PDs. Compared with current and resistance analysis, the LLDP function provides a more comprehensive and accurate analysis.
Procedure
- Run system-view
The system view is displayed.
- Run wlan
The WLAN view is displayed.
- Run ap lldp enable
LLDP is enabled in the WLAN view.
By default, LLDP is enabled in the WLAN view.
- Run the port-link-profile name profile-name command to create an AP wired port link profile and enter the AP wired port link profile view.
By default, the system provides the AP wired port link profile default.
- Run the lldp enable command to enable LLDP on an AP wired port.
By default, LLDP is enabled on an AP's wired interface.
An AP can send and receive LLDP packets only after LLDP is enabled in both the WLAN view and the AP wired port link profile view.
- Run lldp tlv-enable dot3-tlv power
LLDP is configured to advertise Power Via MDI TLV.
By default, LLDP is configured to advertise Power Via MDI TLV.
After LLDP is configured advertise Power Via MDI TLV, the device can analyze the interface type, whether the PSE supports MDI, status of MDI power supply, whether the PSE can control the line pairs and analyze the line pairs and power priority.
- Run lldp dot3-tlv power { 802.1ab | 802.3at }
The standard with which the 802.3 Power via MDI TLV sent by the interface complies is set.
By default, the 802.3 Power via MDI TLV advertised by a UPoE interface and a PoE interface complies with 802.3bt and 802.3at, respectively.
- (Optional) Run lldp tlv-enable legacy-tlv four-pair-power
The AP wired port is configured to advertise Cisco's proprietary TLVs.
By default, an AP's wired interface advertises Cisco's proprietary TLVs.
- (Optional) Run lldp tlv-enable legacy-tlv power-capability
LLDP packets sent by an AP are configured to carry the supported power capability.
By default, the LLDP packets sent by an AP carry the supported power capability.
