Monitoring LLDP Neighbors

Link Layer Discovery Protocol (LLDP) is a Layer 2 neighbor discovery protocol that allows devices to advertise device information to other devices on the network. LLDP enables a station attached to an IEEE 802 LAN or MAN to advertise its capabilities to, and to discover, other stations in the same IEEE 802 LAN segments. By default, the system capabilities are automatically advertised when LLDP is enabled on a global basis.

Complete the following steps to view the LLDP neighbor devices and the ports through which they are connected.

  1. Select Layer 2 > LLDP.

  2. Select LLDP status to enable or disable LLDP globally.
    LLDP is enabled by default.
  3. Select a unit ID box in the stack panel to view the corresponding ports panel of the stack unit.
    All the LLDP neighbor devices in the network and the ports to which they are connected are displayed.
  4. Pause the pointer over a remote device to view the device information such as port number, name, device type, and the MAC address.
  5. Pause the pointer over a connecting port to view the MAC address.
