•
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.
•

Description
This is the internal table index that is automatically assigned and cannot be edited.
This is the valid ID that you have assigned to this specific entry (from 0001 to 4094).
This is the unique name that you
assigned to this specific entry.
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.
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.
