LLDP Interface Configuration

Use the LLDP Interface Configuration page to specify LLDP (Link Layer Discovery Protocol) parameters that are applied to a specific interface.

To access this page, click Switching > LLDP > Interface in the navigation menu.

Note

When adding or editing LLDP settings on an interface, select the appropriate checkbox to enable a feature, or clear the checkbox to disable a feature.

LLDP Interface Summary Fields

Field	Description
Interface	The interface associated with the rest of the data in the row. Only interfaces that have at least one LLDP setting enabled appear in the table. In the Add LLDP Interface window, use this field to select the interface with the LLDP settings to configure. In the Edit LLDP Interface window, this field identifies the interface that is being configured.
Port ID Subtype	The LLDP Port ID subtype of the interface, which is either MAC Address or Interface Name.
Link Status	The link status of the interface, which is either Up or Down. An interface that is down does not forward traffic.
Transmit	The LLDP advertise (transmit) mode on the interface. If the transmit mode is enabled, the interface sends LLDP Data Units (LLDPDUs) that advertise the mandatory TLVs and any optional TLVs that are enabled.
Receive	The LLDP receive mode on the interface. If the receive mode is enabled, the device can receive LLDPDUs from other devices.
Notify	The LLDP remote data change notification status on the interface. If the notify mode is enabled, the interface sends SNMP (Simple Network Management Protocol) notifications when a link partner device is added or removed.
Optional TLV(s)	Select each checkbox next to the TLV (Type Length Value) information to transmit. Choices include: System Name: To include system name TLV in LLDP frames. To configure the System Name, see System Description. System Description: To include system description TLV in LLDP frames. System Capabilities: To include system capability TLV in LLDP frames. Port Description: To include port description TLV in LLDP frames. To configure the Port Description, see Port Description.
Transmit Management Information	Select the checkbox to enable the transmission of management address instance. Clear the checkbox to disable management information transmission. The default is disabled.

Use the buttons to perform the following tasks:

• To configure LLDP settings on an interface that does not have any LLDP settings enabled, click Add.
• To change the LLDP settings for an interface in the table, select the entry to update and click Edit. If you clear (disable) all LLDP settings, the entry is removed from the table.
• To clear (disable) all LLDP settings from one or more interfaces, select each entry to clear and click Remove.

After you click Add or Edit, a window opens and allows you to configure the LLDP settings for an interface. The following information describes the additional fields that appear in the windows used for adding or editing per-interface LLDP settings.

In addition to some of the fields that LLDP Interface Summary Fields describes, LLDP Interface Add Fields shows the additional fields available on the Add LLDP Interface window.

LLDP Interface Add Fields

Field	Description
System Name	Select this option to include the user-configured system name in the LLDPDU the interface transmits. The system name is configured on the System Description page and is the SNMP server name for the device.
System Description	Select this option to include a description of the device in the LLDPDU the interface transmits. The description includes information about the product model and platform.
System Capabilities	Select this option to advertise the primary function(s) of the device in the LLDPDU the interface transmits.
