Configuration: LLDP
Overview
This section provides information for LLDP in Configuration.
Use the Link Layer Discovery Protocol (LLDP) screens to configure LLDP Switch settings.
LLDP Settings
This page allows the user to inspect and configure the current LLDP port settings.
Global Settings
Use this screen to configure the Global settings. Click Configuration > LLDP > Global.
The following table describes the labels in this screen.

Description
Global
State
Select Enable to activate the global LLDP.
Transmission Interval
Enter the transmission interval value.
The switch periodically transmits LLDP frames to its neighbors for having the network discovery information up-to-date. The interval between each LLDP frame is determined by the Tx Interval value. Valid values are restricted to 5 – 32768 seconds.
Hold Multiplier
Enter the hold multiplier value.
Each LLDP frame contains information about how long the information in the LLDP frame shall be considered valid. The LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2 – 10 times.
Reinitialization Delay
Enter the re-initialization delay value.
When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP shutdown frame is transmitted to the neighboring units, signaling that the LLDP information is not valid anymore. Tx Reinit controls the amount of seconds between the shutdown frame and a new LLDP initialization. Valid values are restricted to 1 – 10 seconds.
Transmit Delay
Enter the transmission delay value.
If some configuration is changed (for example, the IP address) a new LLDP frame is transmitted, but the time between the LLDP frames will always be at least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of the Tx Interval value. Valid values are restricted to 1 – 8192 seconds.
LLDP-MED Fast Start Repeat Count
Enter the LLDP-MED fast start repeat count value.
Because there is a risk of an LLDP frame being lost during transmission between neighbors, it is recommended to repeat the fast start transmission multiple times to increase the possibility of the neighbors receiving the LLDP frame. With Fast start repeat count it is possible to specify the number of times the fast start transmission would be repeated. The recommended value is four times, given that four LLDP frames with a 1 second interval will be transmitted, when an LLDP frame with new information is received.

Location Coordinates
Latitude
Latitude SHOULD be normalized to within 0 – 90 degrees with a maximum of four digits.
It is possible to specify the direction to either North of the equator or South of the equator.
Longitude
Longitude SHOULD be normalized to within 0 – 180 degrees with a maximum of four digits.
It is possible to specify the direction to either East of the prime meridian or West of the prime meridian.
Altitude
Altitude SHOULD be normalized to within –32767 to 32767 with a maximum of four digits.
It is possible to select between two altitude types (floors or meters).
Meters: Representing meters of Altitude defined by the vertical datum specified.
Floors: Representing altitude in a form more relevant in buildings which have different floor-to-floor dimensions. An altitude = 0.0 is meaningful even outside a building, and represents ground level at the given latitude and longitude. Inside a building, 0.0 represents the floor level associated with ground level at the main entrance.
Map Datum
The Map Datum is used for the coordinates given in these options:
WGS84: (Geographical 3D) – World Geodesic System 1984, CRS Code 4327, Prime Meridian Name: Greenwich.
NAD83/NAVD88: North American Datum 1983, CRS Code 4269, Prime Meridian Name: Greenwich; The associated vertical datum is the North American Vertical Datum of 1988 (NAVD88). This datum pair is to be used when referencing locations on land, not near tidal water (which would use Datum = NAD83/MLLW).
NAD83/MLLW: North American Datum 1983, CRS Code 4269, Prime Meridian Name: Greenwich; The associated vertical datum is Mean Lower Low Water (MLLW). This datum pair is to be used when referencing locations on water/sea/ocean.

Application
Select the Application type indicating the primary function of the applications defined for this network policy, advertised by an Endpoint or Network Connectivity Device. The possible application types are shown below.
1. Voice – for use by dedicated IP Telephony handsets and other similar appliances supporting interactive voice services. These devices are typically deployed on a separate VLAN for ease of deployment and enhanced security by isolation from data applications.
2. Voice Signaling – for use in network topologies that require a different policy for the voice signaling than for the voice media.
3. Guest Voice – to 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.
4. Guest Voice Signaling – for use in network topologies that require a different policy for the guest voice signaling than for the guest voice media.
5. Softphone Voice – for use by softphone applications on typical data centric devices, such as PCs or laptops.
6. Video Conferencing – for use by dedicated Video Conferencing equipment and other similar appliances supporting real-time interactive video or audio services.
7. 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.
8. Video Signaling – for use in network topologies that require a separate policy for the video signaling than for the video media.
VLAN ID
Enter the VLAN ID (VID) for the port as defined in IEEE 802.1Q-2003. A value of 1 through 4094 is used to define a valid VLAN ID. A value of 0 (Priority Tagged) is used if the device is using priority tagged frames as defined by IEEE 802.1Q-2003, meaning that only the IEEE 802.1D priority level is significant and the default PVID of the ingress port is used instead.
VLAN Tag
TAG is indicative of whether the specified application type is using a tagged or an untagged VLAN. Select Tagged or Untagged.
Untagged: The device is using an untagged frame format and as such does not include a tag header as defined by IEEE 802.1Q-2003.
Tagged: The device is using the IEEE 802.1Q tagged frame format.
L2 Priority
Priority is the Layer 2 priority to be used for the specified application type. One of the eight priority levels (0 through 7).
DSCP Value
DSCP is the DSCP value to be used to provide Diffserv node behavior for the specified application type as defined in IETF RFC 2474. Contain one of 64 code point values (0 through 63).
