Figure 23. LLDP-MED Policies TLV
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 auto | static command. Dell Networking also honors the power value
(power requirement) the powered device sends when the port is configured for power inline
auto
.
