Packet received at subscriber Ethernet interface:
Each packet with this VID (
Connection
VLAN ID field) has the matching VLAN tag
(outermost only) removed and is forwarded over the wireless interface to the sector
controller.
Packet received at subscriber wireless interface (from sector controller):
A VLAN tag is added (outermost) and set to the VID (
Connection
VLAN ID field) for
this
Connection
. The packet is forwarded to the subscriber Ethernet port.
Pass-through : Select pass-through to create a
Connection
to process all untagged
packets and packets where the outermost VLAN ID tag does not match the VID
(
Connection
VLAN ID field) for with this
Connection
. Only one pass-through
Connection
can be defined for each subscriber. If a pass-through
Group
is not configured, all
untagged packets received at the subscriber Ethernet ingress port are discarded.
Packet received at subscriber Ethernet interface:
The packet is forwarded unmodified over the wireless to the sector controller.
Packet received at subscriber wireless interface (from sector controller):
The packet is forwarded unmodified to the subscriber Ethernet port.
Connection VLAN ID : Enter the VLAN ID tag associated with this
Connection
definition.
This field is used only when 'Tagged' is selected in the
Connection
Tagging Mode field.
Default priority : Enter the default 802.1p priority setting.
The default priority setting is used only when the
Connection
Tagging is set to 'pass-
through' mode and the associated
Group
Tagging Mode is set to 'Tagged'. The
Connection
Default Priority value is used when adding the 802.1Q tag (
Group
VLAN ID) to
the packet being forwarded.
Parent Link ID : Enter the
Link ID
for this
Connection
. This is the unique identification
value created automatically when the subscriber
Link
was added. See
Links List
below.

Parent Group ID : Enter the
Group ID
for this
Connection
. This is the unique identification
value created automatically when the subscriber
Link
was added. See
Groups List
below.

Wireless Traffic Parameters
The sector controller allocates bandwidth for all subscribers using the Weighted Round
Robin algorithm with the combined total of all QoS levels acting as weights. The
aggregate QoS settings affect packet delay and jitter values for the entire sector.
It is strongly recommended to calculate
DL QoS
and
UL QoS
levels using the Redline AN-
80i PMP Configuration Tool -- the QoS levels for each
Connection
can be read directly
from the
QoS
column in the
Connection ID Configuration
section. To manually determine
these settings, identify the maximum UL and DL burst rate for the associated
Link
and
calculate the highest available level using the formula:
Burst Rate - 1
.
DL QoS Level : Enter the QoS level for downlink unicast traffic for this connection.
UL QoS Level : Enter the QoS level for uplink unicast traffic for this connection.
