802.1Q Support
Issue 1 August 2006 35
802.1Q Support
The IP DECT base stations support VLANs according to IEEE 802.1Q.
VLAN can be administered:
1. on a per port basis of the LAN switch assuming that the IP DECT base stations are
connected to a single port of a switched Ethernet environment
2. or by advising a VLAN ID to the IP DECT base station respective to the VLAN they should
operating in.
VLAN tagging has only to set to IP DECT base station in case (b). The whole chapter refers to
that case.
The benefit of VLAN tagging by IP DECT base station is to set 802.1p priority within Ethernet
frames (how to set Quality of Service, see
IP Regions on page 49).
The scope of the following description is only the VLAN tagging and obtaining the VLAN ID.
Quality of Service mechanisms like 802.1p priority and DiffServe are not in the scope of this
section.
VLAN implementation notes referring to IP DECT base stations:
●
IP DECT base stations are not be able to support VLAN ID 0 as described later in this
section (see Why not VLAN ID 0 on page 36). Any other valid VLAN ID can be configured.
●
If 802.1Q tagging is enabled and a VLAN ID is configured all traffic from an IP DECT base
station will be tagged with this VLAN ID.
●
Once a VLAN ID is set to the IP DECT base station, incoming frames are only accepted if
they are tagged as well. Therefore the switch port has to be configured as tagged trunk for
this VLAN.
●
The VLAN configurations can be done using DHCP or the interface for the local static
configuration via OM Configurator.
●
The usage of VLAN does influence the boot up process of the IP DECT base station
because the VLAN configuration takes place during the boot up phase (referring to start up
with VLAN see
VLAN and the Boot Phase of a IP DECT base station on page 36).

ADMM running on an IP DECT base station
If the ADMM is running on an IP DECT base station the VLAN ID configured for the IP DECT
base station is used for the ADMM.
