Device > Configure > Cisco Discovery Protocol > Cache 1
This dialog box provides CDP configuration information for the device. CDP is a device discovery protocol that runs on routers, bridges, WBU switches, communication servers and more. Each device periodically sends messages to a multicast address. These messages advertise information about that device, such as name, capabilities, the interface and network address the device is connected to, and the version of IOS software that it is running. This information will be picked up by any other router(s) on the same medium which are listening for CDP advertisements.
