Configuring Security, Quality, and Network Features Configuring VLAN Settings 6 Configuring VLAN Settings 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 SPA9X2. STEP 1 Log in to the web administration interface. STEP 2 Click Admin Login and advanced. STEP 3 Click the System tab. STEP 4 Enter the following parameters: Parameter Enable VLAN Enable CDP VLAN ID Description Choose Yes to enable VLAN. Choose no to disable. Enable CDP only if you are using a Linksys switch. CDP is negotiation based and determines which VLAN the SPA9X2 resides in. If you use a VLAN without CDP (VLAN enabled and CDP disabled), enter a VLAN ID for the SPA9X2. Note that only voice packets are tagged with the VLAN ID. Cisco SPA and Wireless IP Phone Administration Guide 131
