Link Layer Discovery Protocol (LLDP) Neighbors Information on ESW2 350G Series Managed Switches

Objective

Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol that allows network devices to advertise information about them and store information from other directly connected devices. The LLDP Neighbors Information page contains information that was received from neighboring devices. After timeout (based on the value received from the neighbor Time To Live (TLV) during which no LLDP PDU was received from a neighbor), the information is deleted.

Applicable Devices

•ESW2 Series Managed Switches

Software Version

• v1.2.6.28

LLDP Neighbors Information

Step 1. Log in to the web configuration utility and choose Administration > Discovery - LLDP > LLDP Neighbors Information. 

This page contains the following fields:

• Local Port - Number of the local port to which the neighbor is connected.

• Chassis ID Subtype - Type of chassis ID (for example, MAC address).

• Chassis ID - Identifier of the 802 LAN neighboring device's chassis.

• Port ID Subtype - Type of the port identifier that is shown.

• Port ID - Identifier of port.

• System Name - Published name of the device.

• Time to Live - Time interval (in seconds) after which the information for this neighbor is deleted.

Step 2. Select a local port, and click Details.

This page contains the following fields:
