Partitioning is performed at the network device (satellite router or
HX gateway component) level.
When a network is installed, one NMD, called the default NMD,
is automatically provided. Each device belongs to exactly one
NMD.
Management NMDs To limit the number of service offerings that must be managed
and maintained, all value-added resellers (VARs) are presented
with the same set of service offerings (and therefore, profile
groups). Because profile groups are linked to NMDs, all satellite
routers belonging to VARs must reside in the same NMD in the
NMSS.
To allow each individual VAR to monitor and control its own
satellite routers, yet prevent them from accessing other VAR’s
satellite routers, NMSS provides a management NMD
that may
be assigned to each satellite router. Operators can then be
assigned to a management NMD.
Management NMDs differ from configuration NMDs in three
important aspects:
•
A management NMD is optional for a satellite router.
•
Any operator assigned to a management NMD may ONLY be
granted monitor and control privileges to those satellite
routers within the management NMD.
•
No configuration privileges may be granted to any operator
within a management NMD.

The management of traffic encryption keys is performed by the
