SLM-5650A Satellite Modem
Network Processor (NP) Interface
When the SLM-5650A is equipped with the Network Processor (NP) Interface only, Management
Security is an optional feature.
8.6.2.1 Secure Management – NP Interface Only
When the optional NP Interface is installed in the SLM-5650A without the optional TRANSEC
Module Interface, Management Security is optional and the following secure network
management operating alternatives apply:
When Management Security is disabled (i.e., Low Level Security is selected):
•
o Non-secure serial-based network management is allowed for the Base Modem via
Telnet, using the J10 Remote EIA-232/485 Type 'DB-9F' serial port and the menu-
driven Command Line Interface (CLI).
o Non-secure Ethernet-based network management is supported over the NP Interface
using the HTTP (non-secure) Web browser and SNMPv2.
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.
When the modem is operating in BPM (Bridge Point-to-Multipoint) or Dynamic
Point-to-Point (DPP) Mode, 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.
• When Management Security is enabled (i.e., High Level Security is selected):
o Secure network management is supported by the NP Interface, but not by the Base
Modem. The Base Modem's J5 Ethernet port (external Ethernet connectivity to the
Base Modem) is disabled.
o Secure Ethernet-based network management is supported over HTTPS via Secure
Socket Layer (SSL); Secure Shell (SSH) menu-driven Command Line Interface
(CLI); and SNMPv3.
When the modem is operating in Router Mode, a number of Base Modem parameters
are available via the NP HTTPS Interface.
When the modem is operating in BPM or DPP Mode, NP Interface Ethernet ports P1
through P4 transparently bridge data traffic, and network management is only
possible using the J5 Ethernet port on the Base Modem.
When the modem is operating in (Static) Bridge Mode, Ethernet communication
between the Base Modem and the NP Interface is disabled, as the Base Modem does
not support secure network management interfaces.
