Link Layer
Discovery Protocol
Figure 8-1 “Link Layer Discovery Protocol” web page
For devices in the 2000/2100 version, LLDP can be activated or deactivated globally for all
ports. Devices in the 2200/2300 version also offer a port-based configuration option for
sending and receiving LLDP telegrams.
The LLDP can be configured on the “Service” page in WBM (see “Service” on page 40).
