Selecting Vlans For Voip - Extreme Networks EPICenter Reference Manual

The QoS Settings tab lets you view VoIP VLAN QoS settings, change the configuration, and
automatically calculate the minimum bandwidth required.

Selecting VLANs for VoIP

The VoIP Manager module assumes that you have already created the VLAN(s) for your VoIP phone
ports. A VoIP VLAN should include both the edge switches that contain the actual IP phone ports, and
any core switches that lie between the edge and the Call Manager or PBX. You can use the EPICenter
VLAN Manager module to create a VLAN for your voice over IP network, if you have not already done
so. A VLAN that will be used with VoIP traffic should use protocol IP or Any, and may be tagged or
untagged.
If you add a new device to an existing VoIP VLAN (for example, to expand the number of IP phones)
the new device will not be configured automatically as a VoIP VLAN. You will need to select the VLAN
on the new device, and then configure the VoIP settings on that device.
1 To select the VLANs to configure for Voice over IP, click the Voice over IP button in the EPICenter
Navigation Toolbar. The main Voice over IP window appears, as shown in

table shown on this page will be empty.
