Extended Power via MDI TLV
The extended power via MDI TLV enables advanced PoE management between LLDP-MED endpoints and network
connectivity devices.
Advertise the extended power via MDI on all ports that are connected to an 802.3af powered, LLDP-MED endpoint device.
• Power Type — there are two possible power types: power source entity (PSE) or power device (PD). The Dell Networking
system is a PSE, which corresponds to a value of 0, based on the TIA-1057 specification.
• Power Source — there are two possible power sources: primary and backup. The Dell Networking system is a primary
power source, which corresponds to a value of 1, based on the TIA-1057 specification.
• Power Priority — there are three possible priorities: Low, High, and Critical. On Dell Networking systems, the default power
priority is High, which corresponds to a value of 2 based on the TIA-1057 specification. You can configure a different power
priority through the CLI. Dell Networking also honors the power priority value the powered device sends; however, the CLI
configuration takes precedence.
• Power Value — Dell Networking advertises the maximum amount of power that can be supplied on the port. By default the
power is 15.4W, which corresponds to a power value of 130, based on the TIA-1057 specification. You can advertise a
different power value using the max-milliwatts option with the power inline command. Dell Networking also honors
the power value (power requirement) the powered device sends when the PE is configured with
power inline mode
class.

Configure LLDP
Configuring LLDP is a two-step process.
1. Enable LLDP globally.
2. Advertise TLVs out of an interface.
