Configuring LLDP ports

With the Port tab, you can set the optional TLVs to include in the LLPDUs transmitted by each port.

To configure LLDP ports:

Procedure steps
Step Action
1

From the navigation tree, double-click Edit.
2

From the Edit tree, double-click Diagnostics.
3

From the Diagnostics tree, double-click 802.1AB.
4

From the 802.1AB tree, double-click LLDP.
5

Select the Port tab.
--End--

The following table outlines the parameters of the LLDP Port tab.

Variable definitions

Variable Value
PortNum Port number.
AdminStatus

The administratively desired status of the local LLDP agent:

  • txOnly: the LLDP agent transmits LLDP frames on this port and does not store any information about the remote systems to which it is connected.
  • rxOnly: the LLDP agent receives but does not transmit LLDP frames on this port.
  • txAndRx: the LLDP agent transmits and receives LLDP frames on this port.
  • disabled: the LLDP agent does not transmit or receive LLDP frames on this port. If the port receives remote systems information which is stored in other tables before AdminStatus is disabled, the information ages out.
NotificationEnable

Controls, for each port, whether notifications from the agent are enabled.

  • true: indicates that notifications are enabled
  • false: indicates that notifications are disabled.
TLVsTxEnable

Sets the optional Management TLVs to be included in the transmitted LLDPDUs:

  • portDesc: Port Description TLV
  • sysName: System Name TLV
  • sysDesc: System Description TLV
  • sysCap: System Capabilities TLV
Note: The Local Management tab controls Management Address TLV transmission.
VLANTxEnable(dot1) Specifies whether the IEEE 802.1 organizationally defined port VLAN TLV transmission is included in the transmitted LLDPDUs.
TLVsTxEnable(dot3)

Sets the optional IEEE 802.3 organizationally defined TLVs to be included in the transmitted LLDPDUs:

  • macPhyConfigStatus: MAC/PHY configuration/status TLV
  • powerViaMDI: Power over MDI TLV
  • linkAggregation: Link Aggregation TLV
  • maxFrameSize: Maximum-frame-size TLV.
CapSupported(med) Identifies which MED system capabilities are supported on the local system.
TLVsTxEnable(med)

Sets the optional organizationally defined TLVs for MED devices to include in the transmitted LLDPDUs:

  • capabilities: Capabilities TLVs
  • networkPolicy: Network Policy TLVs
  • location: Emergency Communications System Location TLVs
  • extendedPSE: Extended PoE TLVs with PSE capabilities
  • inventory: Hardware Revision, Firmware Revision, Software Revision, Serial Number, Manufacturer Name, Model Name, and Asset ID TLVs.
NotifyEnable(med) A value of true enables sending the topology change traps on this port. A value of false disables sending the topology change traps on this port.
