configure lldp ports vendor-specific med power-via-mdi

configure lldp ports [all | port_list] [advertise | no-advertise] vendor-specific med power-via-mdi

Description

Configures the LLDP port to advertise or not advertise MED power requirement details. This TLV can only be enabled on a PoE-capable port and is used for advanced power management between the MED network connectivity and endpoint devices.

Syntax Description

all Specifies all ports on the switch.
port_list Specifies one or more ports or slots and ports.
advertise Specifies to send the information to neighbors.
no-advertise Specifies not to send the information to neighbors.

Default

No advertise.

Usage Guidelines

When enabled, this LLDP MED TLV advertises fine-grained power requirement details about PoE settings and support. This TLV can be enabled only on a PoE-capable port; the switch returns an error message if this TLV is configured for a non-PoE-capable port.

You must configure the LLDP MED capabilities TLV before configuring this TLV. Configure the LLDP MED capabilities TLV using the configure lldp ports [all | port_list] [advertise | no-advertise] vendor-specific med capabilities command.

As with all the LLDP MED TLVs, the switch sends this TLV only after it detects a MED-capable device on the port. The switch does not automatically send this TLV after it is enabled; the switch must first detect a MED-capable device on the port.

Note

Note

For additional information on power support, see the configure lldp ports vendor-specific dot3 power-via-mdi command.

The following information is transmitted for LLDP MED PoE-capable ports with this TLV:
  • Power type

    Set to PSE.

  • Power source

    Set to primary power source.

  • Power priority

    Taken from PoE port configuration.

  • Power value

    Taken from PoE port configuration.

Example

The following command configures all ports to advertise MED power information to neighbors:
