Configures the LLDP port to advertise or not advertise Power over Ethernet (PoE) capabilities to its neighbors.
|all||Specifies all ports on the switch.|

|no-advertise||Specifies not to send the information to neighbors.|
|with-classification||Specifies to use LLDP for Data
Link Layer Classification.
This option is available only on PoE+ ports.
When configured, the system includes this TLV. We recommend enabling this TLV only on PoE-capable ports.
Support PoE or not
Power sourcing equipment (PSE)
Powered device (PD)
Support pairs control or not
Data link layer classification allows fine-grained dynamic re-allocation of power based on changing needs. This feature is enabled by enabling LLDP (transmit and receive) and configuring transmission of the power-via-MDI TLV. The ExtremeXOS software sends an LLDPDU containing a power-via-MDI TLV within 10 seconds of DLL classification being enabled. A PD may request a new power value using an LLDPDU. The allocated power might be changed if a request is received and approved after a power review. The software responds with an allocated power value within 10 seconds of receipt of an LLDPDU with a different requested power from a PD. Power allocation can be controlled to a granularity of 0.1 watts. When DLL classification is enabled, it takes precedence over physical classification.
For more information on advertising power support, see the configure lldp ports vendor-specific med power-via-mdi command.
The following command configures all ports to advertise power capabilities to neighbors:
configure lldp ports all advertise vendor-specific dot3 power-via-mdi
This command was first available in ExtremeXOS 11.2.
This command is available on ExtremeSwitching 5320, 5420, 5520, and 5720 series switches.
