Configuring the Cisco Discovery
Protocol
The Cisco Discovery Protocol (CDP) is a medium-independent protocol that runs
over Layer 2 (the data link layer) on the CSS and other Cisco manufactured
equipment, such as routers, switches, bridges, and access servers. Use the cdp
global configuration command to allow the CSS to advertise itself to all other
neighboring Cisco CDP-compatible devices on a network. The CSS only
transmits CDP advertisements to other CDP-compatible devices on the network;
the CSS does not listen for CDP messages from the other CDP-compatible
devices, and does not maintain a CDP table.
Any Cisco device with CDP support can learn about the CSS by listening to the
periodic messages transmitted by the CSS and determining when the CSS is
active. Network operators and analysts can use this information for configuration
monitoring, topology discovery, and fault diagnosis.
CDP messages contain specific information about the CSS, such as:
• Device ID (CSS base MAC address)
• IP address (CSS management port IP address)
• Ethernet port ID name
• CSS functional capability flag (Router, Transparent Bridge, or Switch)
• CSS software version
• CSS platform
CDP advertisements also include hold time information, which defines the length
of time the receiving device is to hold CDP information before discarding it.
