2.9 Interoperability with Cisco Discovery Protocol
Dell Networking N-Series switches participate in the Industry Standard Discovery Protocol (ISDP) and are
able to both discover and be discovered by devices that support the Cisco Discovery Protocol (CDP). ISDP is
a proprietary Layer 2 network protocol that inter-operates with Cisco network equipment and is used to share
information between neighboring devices. ISDP is running by default and does not require any additional
configuration to work with other ISDP or CDP enabled devices.
