NOTE: As shown in the following table, signaling is a series of control packets that are exchanged between an endpoint device
and a network connectivity device to establish and maintain a connection. These signal packets might require a dierent network
policy than the media packets for which a connection is made. In this case, congure the signaling application.
Table 37. Network Policy Applications
Type Application Description
0 Reserved —
1 Voice Specify this application type for dedicated IP telephony handsets
and other appliances supporting interactive voice services.
2 Voice Signaling Specify this application type only if voice control packets use a
separate network policy than voice data.
3 Guest Voice Specify this application type for a separate limited voice service
for guest users with their own IP telephony handsets and other
appliances supporting interactive voice services.
4 Guest Voice Signaling Specify this application type only if guest voice control packets
use a separate network policy than voice data.
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.
8 Video Signaling Specify this application type only if video control packets use a
separate network policy than video data.

Figure 66. 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 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
Link Layer Discovery Protocol (LLDP)
