section is not applicable to the WIP310.)

Configuring Cisco Discovery Protocol (CDP)

If you are using a Cisco switch, Cisco discovery protocol (CDP) is enabled. CDP is
enabled by default. CDP is negotiation-based and determines which VLAN the IP
phone resides in. CDP:
• Obtains the protocol addresses of neighboring devices and also discovers
the platform of those devices.
• Shows information about the interfaces your router uses.
• Is media and protocol-independent.
If you are using a VLAN without CDP, you must enter a VLAN ID for the IP phone.
