14 In the Add IP Interface dialog box, select the router or layer-3 switch that
you wish to use to route to the VLAN and enter a suitable IP address and
subnet mask for its interface on the new VLAN. Add the interface by
clicking OK.
15 Click Next to move onto the Summary step of the wizard and click Finish
to apply the changes to your network.
The NBX system can be configured so that the phones and NBX call
processors use VLAN tags directly. If you use the internal switch or hub of
the phones to connect end stations to your network, or wish to use the
802.1p priority tag to prioritize your phone traffic then you may wish to
enable tagging on the NBX system. Please refer to the user guide for your
NBX call processor for details of how to do this.
If you do enable tagging on the NBX system then when you run the
Create VLAN wizard you will need to enable tagging on the phone and
NBX call processor ports. To enable tagging, click Change Selection in the
Edit Ports step of the wizard to launch the Selection Editor dialog box,
locate and select all of the ports currently selected as untagged members
of the VLAN, click Add Port (Tagged) to change the ports to tagged
members of the VLAN and click OK to close the dialog box.
