GbE Channel Redundancy
The NSG family supports GbE redundancy to provide the network with
fault-tolerant design. The objective of the redundant channel is to
eliminate or diminish any service interruptions when an active GbE

Recommended Tool
MCT (Mass Configuration Tool).
The MCT is a spreadsheet-oriented system designed to
configure multiple NSGs simultaneously. MCT is
recommended for large-scale NSG deployments. Besides
simultaneous configuration of large number of NSG
devices, it also allows users to perform firmware upgrade
for multiple NSGs. MCT is sold separately - please contact
Harmonic Customer Support for more details.
Note: MCT is not automatically updated when an NSG is
configured through the web client. Using the web client
for configuring individual NSGs in an MCT-based site is
not recommended. If the web client is used, care should
be taken to update MCT with the changed configuration.
For details on synchronizing MCT with NSG devices,
please refer to the MCT online help.
Harmonic NMX / 3rd party SNMP monitoring.
NMX (Harmonic's Digital Service Manager) may be used
for monitoring general status and alarms of multiple NSG
devices. A single NMX manager may be used to monitor
several hundreds NSG devices, located in several different
sites.
In addition, NSG may report its status and alarms via
standard SNMP. Any standard-based SNMP monitoring
system may be used for monitoring the status of multiple
NSG devices. This includes off-the-shelf systems such as
HP OpenView, or custom-made systems. For further
details on implementing SNMP monitoring for NSG
devices, please contact Harmonic Customer Support.
