Using the IP Phones in a VLAN

If you use a VLAN your IP phone voice packets are tagged with the VLAN ID. (This
section is not applicable to the WIP310.)
If you are using a Cisco switch, Cisco discovery protocol (CDP) is enabled (this is
the 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.
Log in to the web administration interface.
