Comtech EF Data VMS v3.12.x Vipersat - Manual (Page 269)

Chapter 4 - Configuring Network Modems 4-51
MN/22156, rev 12 Network
Valid range is 49152 to 65534.
Multicast Address
The Multicast Address is the management multicast IP address assigned to all
modem units in the Vipersat network that are managed by the VMS. This
address must match the VMS Transmit Multicast Address (see section “Viper-
sat Manager Configuration” on page 3-12).
When the modem unit receives a multicast from the VMS server, it receives
maintenance and control packets, including the server’s IP address. The unit
responds to the VMS server with a unicast containing its current configuration
data, including the unit’s IP address. When the VMS receives the unicast
response, it registers the unit on the network.
SNMP Trap Destination IP Address
Enter the IP address of the SNMP manager/server that the trap messages are to
be sent to. Note that this address must be on the same subnet as the management
interface address, or the management interface must have a valid default gate-
way defined. Only unicast addresses are valid for this parameter.
The default value, 0.0.0.0, disables this function (no traps sent).
Network | Switching
This menu item appears for CDM-840 units only.
Note: If the Dynamic SCPC feature (FAST code) has not been purchased for
this modem/router, the Switching menu item will not be displayed.
Once a Remote unit is switched from Entry Channel Mode into dSCPC mode,
additional switching can be initiated by the Remote, based on either changes in
Load and/or application of ToS (Type of Service).
Network | Switching | Load
This menu item appears for CDM-840 units only.
Load switching is an automatic switching function where the system detects
variations in data rate and will switch the SCPC carrier based on bandwidth
requirements. This additional switching as a result of load variation is deter-
mined by the parameter settings that are made here (figure 4-33).
