The Link Layer Discovery Protocol (LLDP) Menu Bar displays the status.

Access to LLDP is located on the ONT UNI Port Menu Bar.

The LLDP parameters include the following:

• 802.3 - 
  • MAC/PHY Configuration - Determines the auto negotiation settings of the port
    • Enable - 
      • Indicates that auto-negotiation is enabled on the device's port.
      • Auto-negotiation allows devices to automatically exchange information about supported physical layer parameters, such as speed and duplex mode, to configure a compatible connection.
    • Disable - 
      • Indicates that auto-negotiation is disabled on the device's port.
      • When auto-negotiation is off, the port operates at a fixed speed and duplex setting.
  • Auto-Negotiation Status -
    • 0: Auto-negotiation not supported
    • 1: Auto-negotiation supported and enabled
    • 2: Auto-negotiation supported but not enabled
    • 3: Auto-negotiation supported but disable
  • Capability - Determines signal speed capabilities (i.e. 1000 BaseT FD)
  • MAU Type - Media Attachment Unit (MAU) defines the type of ethernet port on the far end.
    • 10BT, 100BTX, 1000BT, etc.
• Basic - 
  • Chassis ID - Represents the chassis identification for the device that transmitted the LLDP frame. The receiving LLDP agent combines the Chassis ID and Port ID to represent the entity connected to the port where the frame was received.
  • Port ID - Represents the identification of the specific port that transmitted the LLDP frame. The receiving LLDP agent combines the Chassis ID and Port to represent the entity connected to the port where the frame was received.
  • TTL - Time To Live (TTL) represents the length of time that information contained in the receive LLDP frame shall be valid. If a value of zero is sent it can also identify a device that has shut down or is no longer transmitting, prompting deletion of the record from the local database.
• MED - Endpoint Devices (MED) is an extension to LLDP that operates between endpoint devices such as IP phones and network devices such as switches. It specifically provides support for voice over IP (VoIP) applications and provides additional TLVs for capabilities discovery, network policy, Power over Ethernet, and inventory management.
  • MED Capabilities - Selecting capabilities enables the LLDP-Med extensions, of which Network Policy is the only extension available at this time. If Capabilities is selected, remaining options in this TLV are enabled.
  • Class - MED endpoint devices are, by definition, located at the network edge and communicate using the MED framework. Any MED endpoint device belongs to one of the following three classes:

• Class 1 (generic endpoint devices): These devices offer the basic LLDP discovery services, network policy advertisement (VLAN ID, Layer 2/802.1p priority, and Layer 3/DSCP priority), and PoE management. This class includes such devices as IP call controllers and communication-related servers.
• Class 2 (media endpoint devices): These devices offer all Class 1 features plus media-streaming capability, and include such devices as voice/media gateways, conference bridges, and media servers
• Class 3 (communication devices): These devices are typically IP phones or end-user devices that otherwise support IP media and offer all Class 1 and Class 2 features, plus location identification and emergency 911 capability, Layer 2 switch support, and device information management.
