Configures the LLDP port to advertise or not advertise Power over Ethernet (PoE) capabilities to its neighbors.
| 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. |
| with-classification | Specifies to use LLDP for Data
Link Layer Classification. This option is available only on PoE+ ports. |
No advertise.
When configured, the system includes this TLV. We recommend enabling this TLV only on PoE-capable ports.

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.
Note
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 X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, X690, and X695 series switches.
