Chapter 3 - VMS Configuration 3-3

Hardware Configuration

Note: For VMS compatibility, see the product Release Notes for specific

versions of each modem supported.

Once all of the needed information is obtained, configuration can begin. Before

making the physical installation of hardware into a network, each modem/router

must be pre-configured using either Telnet (CLI) or HTTP. Refer to the modem/

router’s documentation for details.

Comtech EF Data ships all modem/routers with FAST Codes pre-configured.

The modem/routers are always configured at the factory as type Remote, with

the Default Gateway pointed toward the Satellite, and with STDMA disabled.

At this point, VMS cannot discover the node. The operator can either use Telnet

(CLI) or HTTP to set up these parameters as shown in the example

CDM-570/

570L

CLI interface shown in figure 3-2, or flash a configuration file using

VLoad.

As a minimum, the following items in the modem/router will have to be config-

ured before it will be able to communicate with the VMS following installation

in the network:

• Network ID

• Receive Multicast Address

• Managing IP address is set through reception of VMS announcement

multicast message that is sent continuously on timed intervals.
