Configuring VLAN Settings for IP Phones
If you use a VLAN your IP phone voice packets are tagged with the VLAN ID. (This
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.
NTP Enable Enables Network Time Protocol (NTP).
Applies to the SPA525G only.
Primary NTP Server IP address or name of primary NTP server. The phones
use these servers to synchronize its time. Defaults to
blank.
Secondary NTP Server IP address or name of secondary NTP server. The
phones use these servers to synchronize its time.
Defaults to blank.
Enable Bonjour (SPA525G/
525G2 only)
Enable Bonjour networking that is used by Office
Manager and Cisco Configuration Assistant to discover
the Cisco IP phones. Choose yes to enable or no to
disable.
