Vipersat Configuration
3-52 Vipersat CDM-570/570L User Guide
When the CDM-570/570L receives a multicast from the VMS server, it receives
maintenance and control packets, including the server’s IP address. The
CDM-570/570L responds to the VMS server with a unicast containing its
current configuration data, including the CDM-570/570L’s IP address. When
the VMS receives the unicast response, it registers the CDM-570/570L on the
network.
Enter V at the command prompt in the Vipersat Configuration screen
(figure 3-6) to display the dialog shown in figure 3-70.
Figure 3-70 Receive Multicast IP Address prompt
Enter the Receive Multicast Address as assigned by the network operator/
administrator.
Managing IP Address
The Managing IP Address command in the Vipersat Configuration screen
(figure 3-6) allows the IP address for the server running VMS to be entered.
Enter I at the command prompt to display the dialog shown in figure 3-71.
Figure 3-71 Managing IP address menu
The Managing IP Address of the VMS is sent out with the multicast to all of the
Vipersat units and will be automatically updated during the registration process.
The CDM-570/570L sends a unicast registration request to the Managing
Address every 60 seconds when requesting initial registration on the VMS
network. Later, the CDM-570/570L uses this address to send switch requests,
network health status messages, etc. to the managing VMS server.
Note: The managing address will be set automatically if the Receive Multicast
Address is configured correctly and the modem is receiving the
announcement multicast message. However, the modem WILL NOT
send its registration request message until this address is set.
NOTE
