Vipersat Configuration MN/22137, rev 1
3-42 Vipersat CDD-56X Series User Guide
Once the unit is registered, the I command is removed from the Vipersat
Configuration menu.
This managing address is automatically updated on a periodic basis for units
that are newly enabled, incorrectly set, or following VMS changeovers (redun-
dancy switching). The status of the registration process is displayed for this
parameter as follows:
• NOT-DEFINED — unit has booted up, but is unaware of the managing
address.
• No STDMA Xmit Grant — operator has entered managing address, but
unit (Remote) is not currently receiving burst maps.
• Sending Registration (n) — unit is receiving burst maps and the number
of registration attempts (n) is displayed.
• Registered — unit is registered with the VMS. For VMS v3.6.0 and later,
the VMS version number is also displayed (as shown in figure 3-6).
Management Security
Management Security is an optional Vipersat feature that provides encryption
on all VMS management messages passed between the VMS and the network
modems. When enabled, the VMS and all of the network modems must utilize a
common Encryption Key that is manually set on each. The key can be entered
either as an ASCII hex string of exactly 64 characters, or as a passphrase
consisting of 5 to 63 characters.
For modems that operate with Management Security, Enable this feature and
enter the Encryption Key that has been defined for the network.
Note: VMS version 3.7.1 or greater is required for Management Security.
Caution: During the process of network-wide key distribution and enabling of
encryption, communications may be lost as the STDMA control
messages will be unreadable until all modems in the network are
configured.
It is recommended that each of the Remote units be configured for
Management Security first, and then the Hub units be configured.
This method will reduce the need for on-site personnel during feature
implementation.
If the FAST feature key for Management Security has been purchased for the
target modem, then it will appear as a menu item on the Vipersat Configuration
screen (figure 3-6).
