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
Description
Enable VLAN
Choose Yes to enable VLAN. Choose no to
disable.
Enable CDP
Enable CDP
only if you are using a Linksys
switch. CDP is negotiation based and
determines which VLAN the SPA9X2 resides in.
VLAN ID
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.
