Managing the Link Layer Discovery Protocol (LLDP)

Link Layer Discovery Protocol (LLDP) is a protocol that allows stations attached to an IEEE 802 LAN to advertise to one another. Three types of information are advertised: the major capabilities provided by the system incorporating that station, the corresponding management addresses, and the identification of the station’s point of attachment to the IEEE 802 LAN required by those management entities.

The unit uses LLDP to advertise connectivity and management information about itself to adjacent stations, as well as to receive and display network management information from adjacent stations residing on the same IEEE 802 LAN.

To view and manage LLDP information

1. Access the page Show ▶LLDP.
   The total number of ports found in the system is given in the lower-left corner of the page, as well as the index values of the ports currently displayed on-screen (for example, [1-25] of 254). Use the page navigation links in the lower-right corner of the page to move between the pages of results.

2. (Optional) To limit the view to only certain ports, enter a value on which to filter, then click Search.
