SLM-5650A Satellite Modem
Revision 8
Network Processor (NP) Interface
MN-SLM5650A
8–5
8.5 BPM (Bridge Point-to-Multipoint) Mode
Networks where modems traditionally act as routers – e.g., Vipersat-based satellite communications
systems – and include encryption devices are sometimes incompatible or require difficult and
unwieldy configurations. Additionally, the NP Interface limits the number of allowable route tables.
This, in turn, can limit the overall size of the network, particularly when OSPF (Open Shortest Path
First) dynamic routing protocol is used in the NP Interface.
In order to increase the flexibility and scalability of the satellite network with SLM-5650A
modems, the optional BPM (Bridge Point-to-Multipoint) Mode is a feature available with NP
Interface operation whereby Layer 2 and Layer 3 networks can operate simultaneously. When
BPM Mode is selected, users can operate two independent Layer2 networks and one Layer3
network simultaneously without interfering with each other.
See Appendix E. APPLICATION EXAMPLES for in-depth information about using this
optional FAST Feature.
8.6 Network Processor (NP) HTTP/HTTPS Interface
The remainder of this chapter describes the NP HTTP/HTTPS Interface functionality that not
only integrates a good portion of the SLM-5650A Base Modem HTTP Interface non-secure
operations (outlined in detail in the previous chapter), but also provide operations unique to the NP
HTTP/HTTPS Interface.
8.6.1 HTTP/HTTPS Interface Introduction
The pages for the NP HTTP/HTTPS Interface have been designed to work using either
Microsoft’s Internet Explorer Version 7.0 or higher, or Mozilla Firefox Version 2.0 or higher.
(The examples shown in this chapter use Internet Explorer Version 7.0 – most, but not all, pages
will display properly with Internet Explorer Version 6.0.)
Operation of the Network Processor may be fully monitored and
controlled from the NP HTTP/HTTPS Interface. By rolling the
cursor over the tabs located at the top of each page, the user can
select from the available nested hyperlinks (as shown to the right).
In order to make any Network Processor modifications permanent, all changes made
on any of the NP HTTP/HTTPS Interface pages must be saved before rebooting the
unit.
8.6.2 HTTP/HTTPS Interface Availability via Secure Management Interfaces
Non-secure and secure network management operations are controlled by the Interface Security
Mode setting provided on the Admin | Security page (see Chapter Sect. 8.6.6.2.3 for more
information). Its use is dependent on the options installed in the SLM-5650A Base Modem.
