This information is presented in two sections, one for the 9500 MXC nodes and
terminals, and one for CT Ethernet connection to the network.
Rules, Hints, and Tips for 9500 MXC Nodes and Terminals
Rules, Hints, and Tips
• A router function with dynamic and static routing options is provided within each
9500 MXC node or terminal. Unless otherwise mentioned, reference to the node in
this appendix includes the terminal.
• Each 9500 MXC node is hosted behind its Ethernet NMS port IP address: the node
address is the Ethernet port address.
• Other ports, such as the LINK NMS ports, where the INU can have up to three and
the INUe up to six, can be configured to have:
• An unnumbered port address when the Single IP addressing option is selected in
CT (all ports assume the Ethernet port address), or
• A unique IP addresses when the Interface IP addressing option is selected in CT.
With this option all ports can be uniquely numbered.
• Single IP addressing would normally be used. It is easier to set up a network using
just one IP address for each node, compared to having to specify each port per node.
The single IP address is the node/Ethernet port address.
• Interface addressing allows each port on the 9500 MXC router to be uniquely
numbered. It may be used in instances where:
• There is a need to partition a network for dynamic and static routing. Refer to the
example in Figure D-8 on page D-17.
• There is a need to partition a network for dynamic routing protocols, such as OSPF
routed to RIP routed.
• There is a wish by an operator to adopt an IP address structure, which dictates use
of unique IP addresses for each network interface, and to treat the radio link as a
separately identifiable network.
Note: Unique IP addressing may have application in some larger networks where an
operator wishes to number the radio path as a routed network to conform with
a numbering plan used throughout their network. However, for static routed
networks, doing so would require these interfaces to also be entered in the
static route tables for all network devices.
