Usage Guidelines

Usage Scenario

The 802.3 Power via MDI TLV advertised by an AP's wired interface supports the following formats:
  • 802.1ab format: [ TLV type | TLV information string length | 802.3 OUI | MDI power support | PSE power pair | power class ]
  • 802.3at format: [ TLV type | TLV information string length | 802.3 OUI | MDI power support | PSE power pair | power class | type/source/priority | PD requested power value | PSE allocated power value ]
  • 802.3bt format: [ TLV type | TLV information string length | 802.3 OUI | MDI power support | PSE power pair | power class | type/source/priority | PD requested power value | PSE allocated power value | PD requested power value Mode A | PD requested power value Mode B | PSE allocated power value Alternative A | PSE allocated power value Alternative B | PSE power status | System setup | PSE maximum available power | Autoclass | Power down ]
Based on 802.1ab, 802.3at extends three fields: type/source/priority, PD requested power value, and PSE allocated power value. Based on 802.3at, 802.3bt extends the following fields to provide more detailed UPoE information: PD requested power value Mode A, PD requested power value Mode B, PSE allocated power value Alternative A, PSE allocated power value Alternative B, PSE power status, System setup, PSE maximum available power, Autoclass, and Power down.

Prerequisites

  • The LLDP function has been enabled in both the WLAN view and AP wired port link profile view.
  • APs' wired interfaces are allowed to advertise the 802.3 Power via MDI TLV.

Precautions

Before selecting a format of the 802.3 Power via MDI TLV, you need to know the TLV formats supported by the neighbors. The TLV format on the local device must be the same as that on the neighbors.

Member interfaces of the Eth-Trunk do not support this command.

Example

# Configure the 802.3 Power via MDI TLV advertised by the AP's wired interface to comply with 802.3at.
