Configuration
LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery) is an extension of LLDP intended
for managing endpoint devices such as Voice over IP phones and network switches. The LLDP-MED TLVs
advertise information such as network policy, power, inventory, and device location details. Both LLDP and
LLDP-MED information can be used by SNMP applications to simplify troubleshooting, enhance network
management, and maintain an accurate network topology.

Guest Voice - Support a separate 'limited feature-set' voice service for guest
users and visitors with their own IP Telephony handsets and other similar
appliances supporting interactive voice services.
Guest Voice Signaling (conditional) - For use in network topologies that
require a different policy for the guest voice signaling than for the guest voice
media. This application type should not be advertised if all the same network
policies apply as those advertised in the Guest Voice application policy.
Softphone Voice - For use by softphone applications on typical data centric
devices, such as PCs or laptops. This class of endpoints frequently does not
support multiple VLANs, if at all, and are typically configured to use an
untagged VLAN or a single tagged data specific VLAN. When a network
policy is defined for use with an untagged VLAN (see Tagged flag below),
then the L2 priority field is ignored and only the DSCP value has relevance.
Video Conferencing
Streaming Video - For use by broadcast or multicast based video content
distribution and other similar applications supporting streaming video
services that require specific network policy treatment. Video applications
relying on TCP with buffering would not be an intended use of this
application type.
Video Signaling (conditional) - For use in network topologies that require a
separate policy for the video signaling than for the video media. This
application type should not be advertised if all the same network policies
apply as those advertised in the Video Conferencing application policy.
Tag - Tag indicating whether the specified application type is using a tagged or
an untagged VLAN.
Untagged indicates that the device is using an untagged frame format and as
such does not include a tag header as defined by IEEE 802.1Q-2003. In this
case, both the VLAN ID and the Layer 2 priority fields are ignored and only the
DSCP value has relevance. Tagged indicates that the device is using the IEEE
802.1Q tagged frame format, and that both the VLAN ID and the Layer 2 priority
values are being used, as well as the DSCP value. The tagged format includes
an additional field, known as the tag header. The tagged frame format also
includes priority tagged frames as defined by IEEE 802.1Q-2003.
VLAN ID - VLAN identifier for the port. (Range: 1-4095)
L2 Priority - Layer 2 priority used for the specified application type. L2 Priority
may specify one of eight priority levels (0 - 7), as defined by IEEE 802.1D-2004.
A value of 0 represents use of the default priority as defined in IEEE 802.1D-
2004.
DSCP - DSCP value used to provide Diffserv node behavior for the specified
application type as defined in IETF RFC 2474. DSCP may contain one of 64
code point values (0 - 63). A value of 0 represents use of the default DSCP
value as defined in RFC 2475.
Every port may advertise a unique set of network policies or different attributes for
the same network policies, based on the authenticated user identity or port config-
uration.
Port - The port number for which the configuration applies.
Policy ID - The set of policies that apply to a given port. The set of policies is
selected by marking the check boxes that correspond to the required policies.
