DDM Rx Power:  Port Traps Port Select: Select: Port: Link Status: If selected, the switch will send a DDM Rx Power trap when the value of DDM Rx power exceeds the threshold. Click the Select button to quick-select the corresponding port based on the port number you entered. Select your desired port for configuration. It is multi-optional. Displays the port number. Enable/Disable Link Status traps for the desired port. Note: To enable the Link Status traps for the desired port, please select the "Link Status" on the SNMP Traps first, otherwise, it will not take effect. 14.3 RMON RMON (Remote Monitoring) basing on SNMP (Simple Network Management Protocol) architecture, functions to monitor the network. RMON is currently a commonly used network management standard defined by Internet Engineering Task Force (IETF), which is mainly used to monitor the data traffic across a network segment or even the entire network so as to enable the network administrator to take the protection measures in time to avoid any network malfunction. In addition, RMON MIB records network statistics information of network performance and malfunction periodically, based on which the management station can monitor network at any time effectively. RMON is helpful for network administrator to manage the large-scale network since it reduces the communication traffic between management station and managed agent.  RMON Group This switch supports the following four RMON Groups defined on the RMON standard (RFC1757): History Group, Event Group, Statistic Group and Alarm Group. RMON Group History Group Event Group Statistic Group Alarm Group Function After a history group is configured, the switch collects and records network statistics information periodically, based on which the management station can monitor network effectively. Event Group is used to define RMON events. Alarms occur when an event is detected. Statistic Group is set to monitor the statistic of alarm variables on the specific ports. Alarm Group is configured to monitor the specific alarm variables. When the value of a monitored variable exceeds the threshold, an alarm event is generated, which triggers the switch to act in the set way. The RMON Groups can be configured on the History Control, Event Config and Alarm Config pages. 253

14.3 RMON
RMON (Remote Monitoring) basing on SNMP (Simple Network Management Protocol)
architecture, functions to monitor the network. RMON is currently a commonly used network
management standard defined by Internet Engineering Task Force (IETF), which is mainly used to
monitor the data traffic across a network segment or even the entire network so as to enable the
network administrator to take the protection measures in time to avoid any network malfunction. In
addition, RMON MIB records network statistics information of network performance and
malfunction periodically, based on which the management station can monitor network at any time
effectively. RMON is helpful for network administrator to manage the large-scale network since it
reduces the communication traffic between management station and managed agent.
RMON Group
This switch supports the following four RMON Groups defined on the RMON standard (RFC1757):
History Group, Event Group, Statistic Group and Alarm Group.
RMON Group
Function
History Group
After a history group is configured, the switch collects and records network
statistics information periodically, based on which the management station
can monitor network effectively.
Event Group
Event Group is used to define RMON events. Alarms occur when an event is
detected.
Statistic Group
Statistic Group is set to monitor the statistic of alarm variables on the specific
ports.
Alarm Group
Alarm Group is configured to monitor the specific alarm variables. When the
value of a monitored variable exceeds the threshold, an alarm event is
generated, which triggers the switch to act in the set way.
The
RMON
Groups can be configured on the
History Control, Event Config
and
Alarm Config
pages.
