Chapter 55 Configuring a VolP Network Configuring VolP ona Switch Wi Auxiliary VLAN Configuration Guidelines This section describes the guidelines for configuring the auxiliary VLANs e An auxiliary VLAN port is operationally a trunk even though it is not treated like a normal trunk port When an auxiliary VLAN is added to a port and the set dot1q all tagged command is enabled the set dotlq all tagged command tags the native VLAN on the port where the auxiliary VLAN is configured A port with an auxiliary VLAN configured is not viewed as an 802 1Q trunk in the show trunk command output but the port acts like an 802 1Q trunk if the set dot1q all tagged command is enabled e The IP phone and a device that is attached to the phone are in the same VLAN and must be in the same IP subnet if one of the following occurs They use the same frame type The phone uses 802 1p frames and the device uses untagged frames The phone uses untagged frames and the device uses 802 1p frames The phone uses 802 1Q frames and the auxiliary VLAN equals the native VLAN e The IP phone and a device that is attached to the phone cannot communicate if they are in the same VLAN and subnet but use different frame types because the traffic between the devices in the same subnet is not routed routing would eliminate the frame type difference e You cannot use the switch commands to configure a frame type that is used by the traffic that is
