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
different network policy than the media packets for which a connection is made. In this case, configure the signaling
application.
Table 41. 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 71. 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
