Configure and Monitor LLDP Activity and Status
LLDP-MED (Media Endpoint Discovery) is an extension to LLDP that operates between
endpoint devices to support voice-over-IP applications. In Prisma SD-WAN Monitor the LLDP
activity on per port basis.
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.
- Select , select the device you want to configure and select theSystemtab.
- Select theStatsicon 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 theLLDP Neighbors. - View the LLDP activity by selecting theView Activityoption.The Activity page displays report on LLDP total frames received, transmitted, and failed transmissions.
