LLDP-MED (Media Endpoint Discovery) is an extension to LLDP that operates between endpoint devices to support voice-over-IP (VoIP) applications. LLDP-MED allows a device to determine the capabilities of a connected device, neighbors, and if these capabilities are enabled.
The device is capable of operating in receive-only mode or transmit-and-receive mode for LLDP. By default, all non-PoE ports are set to receive-only mode and PoE ports are set to transmit-and-receive mode. All the ports are set to default LLDP TLVs until the port receives LLDP-MED TLVs. Change the LLDP configuration at the interface level on the Prisma SD-WAN user interface.
The following LLDP and LLDP-MED TLVs are currently supported:
  • LLDP TLVs
    • Chassis ID
    • Port ID
    • TTL
    • System Name
    • System Description
    • System Capabilities
  • LLDP-MED TLVs
    • LLDP-MED Capabilities
    • Extended Power-via-MDI
    • Inventory Management
      • Hardware Revision
      • Software Revision
      • Firmware Revision
      • Serial Number
      • Manufacturer Name
      • Model Name
Monitor the LLDP activity on per port basis. Each interface display details of up to 10 LLDP neighbors at any given time. An additional neighbor entry causes the oldest neighbor to age out based on the association time. The LLDP neighbor entries are cleared out when the interface operational state is Down or when a powered device (PD) is disconnected from a PoE port.
  1. Select WorkflowsDevicesClaimed Devices, select the device you want to configure and select the System tab.
  2. Select the Stats icon on the LLDP table.
    Select All Interfaces or select any particular port or switch port to view the LLDP status.
    You can also view the interfaces of the LLDP Neighbors.
  3. View the LLDP activity by selecting the View Activity option.
    The Activity page displays report on LLDP total frames received, transmitted, and failed transmissions.
