Remote Monitoring
RMON is a standard MIB that defines current and historical MAC-layer statistic and control
objects, allowing network manager to capture real-time information across the entire network. The
RMON standard is an SNMP MIB definition described in RFC 1757 for Ethernet.
A typical RMON configuration consists of a central network management station and a remote
monitoring device, called an RMON agent (for e.g., the FS-24 switch is a RMON agent). From the
management station, one can issue SNMP commands requesting information from the RMON
agent. The RMON agent (e.g. FS-24 switch) sends the requested information to the management
station. The MIB allows a network agent to be configured to perform diagnostics and to collect
statistics continuously, even when communication with the management station may not be
possible or efficient. The network agent may then attempt to notify the management station when
an exceptional condition occurs.
The FS-24 switch supports 1, 2, 3, & 9 RMON related MIB group. The RMON information can be
retrieved from the switch only via SNMP interface by the SNMP Management station (an SNMP
manager)..
The following RMON groups are supported by the FS-24 switch:
•
Event Group - Event group controls the generation & notification of events from the FS-24
switch. It consists of eventTable and logTable. Each entry in eventTable describes the
parameters of the event that can be triggered. Event is a type of action to be taken, for e.g., a
link may be turned up or down based on an event.
•
Alarm Group - The alarm group module periodically collects statistical samples from the FS-
24 switch and compares them to pre-defined default values. The switch creates one default
value for each active physical port. These default entries define alarm Interval time to be 30
seconds, i.e. time for each sample.
•
History Control Group - The History Control Group controls periodic statistical sampling of
data from various types of interfaces. This group consists of history control table.
•
Ethernet Statistic Group - The Ethernet statistic group contains statistics measured by the FS-
24 switch for each monitored Ethernet interface. This group consists of Ether Stats Table.The
switch implements Ether Stats Table. The Ether Stats Table consists of list of Ethernet statistics
entries such as etherstatsPkts64Octets, etherstatsPkts128to255Octets, and
etherstatsPkts256to255Octets
