Type Application Description
5 Softphone Voice Specify this application type only if guest voice control packets
use a separate network policy than voice data.
6 Video Conferencing Specify this application type for dedicated video conferencing
and other similar appliances supporting real-time interactive
video.
7 Streaming Video Specify this application type for dedicated video conferencing
and other similar appliances supporting real-time interactive
video.

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 specication.
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 specication.
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 specication. You can congure a dierent power priority through the
CLI. Dell Networking also honors the power priority value the powered device sends; however, the CLI conguration 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 specication. You can advertise a dierent 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 congured for
power inline auto.
