ADMM running on a Linux Server
The ADMM running on a dedicated LINUX server requires IP 802.1p support of the server or
will use static QoS administration in the Ethernet switch, so that the ADMM signalling traffic is in
the voice VLAN.
Principles and Parameter
The default is not to tag the traffic. 802.1Q tagging is enabled if the VLAN ID is set. The
configuration of the VLAN ID can be done using
●
DHCP Public option 225
●
by local static configuration of the IP DECT base station via OM Configurator.
If no VLAN ID is set 802.1Q is disabled.
Why not VLAN ID 0
VLAN ID 0 means that the IP DECT base station’s traffic belongs on the port/native VLAN. The
Ethernet switch port to which the IP DECT base station is connected must be configured to
accept 802.1Q tagging for this to work, and the switch must interpret VLAN ID 0 as the port/
native VLAN ID, per the IEEE 802.1Q standard.
The packets from the IP DECT base station are tagged with VLAN ID 0 and the packets send to
the IP DECT base station are tagged with the port/native VLAN ID.
This scenario does not
work, because the IP DECT base station supports only one VLAN ID in both directions.
That means the VLAN ID in receive direction has to be the same like in send direction.
VLAN and the Boot Phase of a IP DECT base station
DHCP
Because the base station does not know any VLAN during the beginning of the start up two
DHCP scopes are required (This procedure applies regardless of the Ethernet switch being
used):
The following scenario with arbitrary VLAN IDs details the steps a IP DECT base station would
go through in a typical dual-VLAN implementation.
