SLM-5650A Satellite Modem
Revision 10
Appendix E E–19 MN-SLM-5650A
Non-Vipersat Multipoint Modes
Item Description
Multipoint Hub Router When in static SCPC (non-Vipersat mode), the option exists for configuring the modems
into a hub and spoke network with a shared outbound at the hub. All of the modems at
the hub should be put in “Multipoint Hub Router” mode.
If a modem at the remote is configured to be a Hub router there will be
significant degradation to network performance due to the potential for
routing loops.
Multipoint Remote
Router
Select Multipoint Remote Router for all remote modems in a non-Vipersat multipoint
network. A Remote router would be classified as a modem which receives the shared
outbound and transmits back to the hub on a dedicated SCPC channel
Non-Vipersat Point-to-Point Mode
Item Description
Point-to-Point Router
Select for use in a Point-to-Point SCPC link where there are different IP subnets on either
side of the link.
Routing Mode
Item Description
Gigabit
Ethernet
Bridge
Select for use in a Point-to-Point SCPC link when you wish to bridge traffic (no IP network routing).
This mode is currently only compatible with the Gigabit Ethernet bridge card for the
SLM-5650A. Ethernet communication between the Base Modem and the NP Interface is
disabled, as the Base Modem does not support secure network management interfaces.
Router
When the modem is operating in Router Mode, a number of Base Modem M&C parameters are available via
the NP HTTP Interface. Similarly, a limited number of status-only NP parameters are viewable over the Base
Modem HTTP Interface.
BPM
Changing the Bridge Mode will leave QOS On. QOS should be turned Off prior to
setting the Bridge Mode.
When you select BPM Mode, the NP Interface Ethernet ports P1 through P4 transparently bridge data traffic,
and network management is only possible using the Base Modem’s J5 Ethernet port.
In BPM Mode, the Gigabit Ethernet Bridge option becomes inaccessible and the
appearance of the Routing Mode section changes as follows:
