Comtech EF Data SLM-5650A Vipersat - Manual (Page 51)

Chapter 3 - Using the Web Server Interface (WSI) 3-11
Vipersat Configuration
The Network ID is used by the VMS to identify units that are common to a
network and allows the VMS to manage multiple networks, each with its own
unique Network ID number.
Receive Multicast Address
The Receive Multicast Address is the multitcast IP address assigned to all
SLM-5650A units in the Vipersat network that are managed by the VMS server.
This address must match the VMS Transmit Multicast Address.
When the SLM-5650A receives a multicast from the VMS server, it receives
maintenance and control packets, including the server’s IP address. The SLM-
5650A responds to the VMS server with a unicast containing its current config-
uration data, including the SLM-5650A’s IP address. When the VMS receives
the unicast response, it registers the SLM-5650A on the network.
Enter the Receive Multicast Address as assigned by the network operator/
administrator.
Managing IP Address
The Managing IP Address parameter corresponds to the IP address of the
server running the VMS.
This address is sent out with the VMS multicast to all of the Vipersat units and
will be automatically updated during the registration process. The SLM-5650A
sends a unicast registration request to the managing address every 60 seconds
when requesting initial registration on the VMS network. Later, the SLM-
5650A 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.
This managing address is automatically updated on a periodic basis for modems
that are newly enabled, incorrectly set, or following VMS changeovers (redun-
dancy switching).
Heart Beat
This menu item appears for the Hub modem only.
The Heart Beat feature is a redundancy heart beat message for primary Hub
units that provides the option for a periodic communications check message to
be sent from the Hub modem to the VMS for backup recovery in N:M redun-
