Pass-through : Select pass-through to create a
Group
to process all packets that do not
have a VLAN ID, or the outermost VLAN ID tag does not match the VLAN ID for
any
Group
. Only one pass-through
Group
can be defined for each sector controller. If a
pass-through
Group
is not configured, all untagged packets received at the sector
controller Ethernet ingress port are discarded.
Packet received at sector controller Ethernet interface: The packet is forwarded
unmodified over the wireless to all subscribers in this
Group
.
Packet received at sector controller wireless interface (from subscriber): The packet is
forwarded unmodified over the wireless to all subscribers in this
Group
.
If the sector controller Ethernet port is enabled, the packet is also forwarded to the
sector controller Ethernet port.
Group VLAN ID : Enter the VID associated with this
Group
definition.
This field is used only when 'Tagged' is selected in the
Group
Tagging Mode field.
Default Priority : Enter the default 802.1p priority setting.
The default priority setting is used only when the
Group Tagging Mode
is set to 'pass-
through' mode and the associated
Connection Tagging Mode
is set to 'Tagged'. The
Group
Default Priority value is used when adding the 802.1Q tag (
Connection
VLAN ID) to the
packet being forwarded.
SC Ethernet Enable : Controls the sector controller Ethernet port.
Check this box to allow ingress and egress data traffic on the sector controller Ethernet
interface. Uncheck this box ( ) to block all data traffic on the sector controller Ethernet
interface. The sector controller Ethernet port remains available for management traffic.
SS To SS Multicast Enable :
Check this box to enable group multicast traffic between subscribers.
Uncheck this box ( ) to block all multicast traffic between subscribers.
Wireless Traffic Parameters
Changes to these settings affect the CIR and PIR for all groups and connections on the
wireless link.
Group QoS Level : This setting represents the range of CIR available to
Group
members
for downlink multicast/broadcast traffic.
It is strongly recommended to calculate the
Group QoS Level
using the Redline AN-80i
PMP Configuration Tool -- the
Group QoS level
can be read from the
QoS
column in the
Group ID Configuration
section. To manually determine this setting, identify the member
Link
having the lowest UBR and calculate the
Group QoS Level
using the formula:
Burst
Rate - 1
. A zero setting disables all DL broadcast and multicast traffic for this group.
Rate : Enter the maximum downlink burst rate for this
Group
.
It is recommended to use the 'auto' setting where the AN-80i selects the most reliable
rate. To manually determine this value, identify the
Group
member having the lowest DL
burst rate, and then set the
Rate
using the formula:
Max DL Burst Rate - 1
. For applications
requiring a higher broadcast/multicast rate (e.g., video), a higher setting can be used at
the risk of less reliable retransmissions.
