Configuring and Viewing ISDP Information
The Industry Standard Discovery Protocol (ISDP) is a proprietary Layer 2 network protocol which inter-
operates with Cisco® devices running the Cisco Discovery Protocol (CDP). ISDP is used to share information
between neighboring devices. D-Link DWS-4000 Series switches participate in the CDP protocol and are able
to both discover and be discovered by other CDP supporting devices.
Global Configuration
