Configures the LLDP (Link Layer Discovery Protocol) port to advertise or not advertise MED power requirement details. This TLV can only be enabled on a PoE (Power over Ethernet)-capable port and is used for advanced power management between the MED network connectivity and endpoint devices.
| 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. |
No advertise.
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
For additional information on power support, see the configure lldp ports vendor-specific dot3 power-via-mdi command.
Power type
