# Configuring LLDP ports

Use this procedure to set the optional TLVs to include in the LLPDUs transmitted by each port.

## Procedure steps

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, click LLDP.

5. Select the Port tab.

The following table outlines the parameters of the Port tab.

Table 1. Variable definitions
Variable | Value
--- | ---
PortNum | Specifies the port number.
AdminStatus | Specifies 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.
