Gazelle S1020i-GL (A) User Manual

5.2.3 Environment monitoring

The principle of environment monitoring is to monitor key parameters of the device, such as
abnormal power status alarm, temperature threshold crossing alarm, and abnormal interface
status. Once anomaly is monitored, you can take measures accordingly to avoid faults.

5.2.4 RMON management

Remote Network Monitoring (RMON) is a standard developed by the Internet Engineering
Task Force (IETF), which is used to monitor network data through different agents and NMS.
RMON which implements statistics gathering and alarms reporting is an extension of SNMP,
but ROMN is more active and efficient for monitoring remote devices. The administrator can
quickly trace faults generated in the network, network segments, or devices.
At present, RMON implements four function groups: statistic group, history group, alarm
group, and event group.

5.2.5 Watchdog

By configuring Watchdog, you can prevent the system program from endless loops due to
uncertain fault, thus improving system stability.

5.2.6 Port mirroring

Port mirroring refers to mirroring packets of the source port to the monitor port without
affecting packets forwarding. You can use this function to monitor the receiving and sending
status of a certain port and analyze the network or fault status.
The Gazelle S1020i-GL supports port mirroring based on ingress port or egress port. When
port mirroring is enabled, packets on the ingress/egress mirroring port will be mirrored to the
monitor port. The monitor port and mirroring port cannot be the same one.

5.3 NView NNM System

5.3.1 Functions

"Comprehensive Access, Overall Network Management" is a vision that Raisecom has been
in pursuit of. The NView NNM system is developed to meet overall and efficient OAM
requirements. It is of complete functions, friendly User Interface (UI), and easy operations,
which can meet requirements for service activation and daily maintenance.
The NView NNM system, based on SNMP, can perform centralized configurations and fault
detection over all manageable devices of Raisecom. It has the following functions:



Topology management: display network topology graphically, organize and manage
nodes of various types and links between these nodes, and support automatic or manual
planning of network functions.
Alarm management: collect, classify, display, and manage all alarms reported by
managed devices. It supports query, sorting, filtering, gathering statistics about,
forwarding, and voice prompt.
Performance management: enable you to view realtime performance or history
performance, such as interfaces, traffic, and bandwidth utilization.
