•
VLAN Brouter Next Hop MAC Address – Enter the desired Next Hop IP Address for toEth
routes. Note that no Next Hop entry is needed for toSat routes.
•
VLAN ID 1 through VLAN ID 10 – You may assign up to 10 VLAN ID addresses within the
range from 0001 to 4095.
VLAN Table (Edit) (with optional Packet Processor INSTALLED)
This section displays the current VLAN ID entries and, when more than one VLAN Entry exists,
allows you to directly edit the selected VLAN ID entry:
Column
Description
Index
This is the internal table index that is automatically assigned and cannot be edited.
ID
This is the valid ID that you have assigned to this specific entry (from 0001 to 4094).
Name
This is the unique name that you
assigned to this specific entry.
Tag
This column identifies the VLAN ID as Native, Management, or Tagged.
•
The Native VLAN ID is used to tag arriving packets that have no VLAN tag. Likewise,
when packets arrive from the WAN with the same VLAN tag as the Native VLAN ID, then
the VLAN header is removed and passed to the LAN interface.
•
The Management VLAN ID is used to specify a dedicated management VLAN used to
access and control the modems.
Priority
The Packet Processor classifies each packet that is to be forwarded over the satellite; the
packet then has a Priority assigned according to the defined QoS Rules:
•
Assign a Priority Level from 0 to 7 for each flow:
•
Any latency critical traffic such as VoIP/RTP should always be assigned Priority 1;
•
Priority 1 packets are forwarded immediately; Priority 2 packets are forwarded as soon as
there are no Priority 1 packets in the Queue; and so on;
•
Any packet that does not meet a QoS Rule is assigned to the Default Rule, and is
assigned Priority 9.
