Using SPA9x2 Phones in a VLAN
Introducing Linksys SPA9x2 Phones
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 SPA9x2 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 SPA9x2. To enter VLAN
settings, see
”Configuring VLAN Settings” section on page 44 .
