lldp dot3-tlv power

lldp dot3-tlv power

Function

The lldp dot3-tlv power command sets the standard to which the 802.3 Power via MDI TLV sent by an interface conforms.

The undo lldp dot3-tlv power command restores the default standard to which the 802.3 Power via MDI TLV sent by an interface conforms.

By default, the 802.3 Power via MDI TLV sent by a UPoE interface conforms to 802.3bt, and the 802.3 Power via MDI TLV sent by a PoE interface conforms to 802.3at.

Format

lldp dot3-tlv power { 802.1ab | 802.3at | 802.3bt }

undo lldp dot3-tlv power

Usage Guidelines

Usage Scenario

The 802.3 Power via MDI TLV has the following formats:
  • 802.1 ab format: [ TLV type | TLV information string length | 802.3 OUI | MDI power support | PSE power pair | power class ]
  • 802.3 at 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 ]
  • 802.3 bt 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 802.1 ab, 802.3 at extends three fields: type/source/priority, PD requested power value, and PSE allocated power value. Based on 802.3 at, 802.3 bt extends three fields: 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 globally and on interfaces.

Precautions

After the global LLDP is disabled, the LLDP configuration is deleted from all interfaces.

Before selecting a format of the 802.3 Power via MDI TLV, you must know the TLV format 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 interface to send the 802.3 Power via MDI TLV conforming to 802.3 at.
