Various devices are connected in network to each other. It becomes a tedious task to keep track of all the devices for network administrator. Checking links physically are also not a good option for network administrator. In case of network consisting of devices from same vendors it may becomes possible to keep track of devices and manage network, but in multi vendor scenario it becomes more difficult. Solution to this is use of Network Discovery Protocol. Network discovery protocol help administrator to find devices connected over network but also helps to find information related to devices. Various vendors have designed their own proprietary discovery protocols, but they are not interoperable in case of devices from different vendors.
