Configuring the RMON alarm function
To enable the managed devices to send traps to the NMS when the NMS triggers an alarm event,

configure the SNMP agent as described in the chapter "SNMP configuration" before configuring
the RMON alarm function.
 If the alarm variables that can be configured through the web interface are MIB variables that
defined in the history group or the statistics group, make sure that the RMON Ethernet statistics
function or the RMON history statistics function is configured on the monitored Ethernet interface.
Perform the tasks in
Table 31 RMON alarm configuration task list
Task
Configuring an event
entry
Remarks
Required
You can create up to 100 statistics entries for a statistics table.
After a statistics entry is created on an interface, the system collects statistics on
various traffic information on the interface. It provides statistics about network
collisions, CRC alignment errors, undersize/oversize packets, broadcasts,
multicasts, bytes received, packets received, and so on. The statistics are cleared
after the device reboots.
IMPORTANT:
Only one statistics entry can be created on one interface.
Remarks
Required
You can create up to 100 history entries for a history table.
After an entry is created, the system periodically samples the number of packets
received/sent on the current interface, and saves the statistics as an instance under
the leaf node of the etherHistoryEntry table.
IMPORTANT:
When you create an entry, if the value of the specified sampling interval is identical
to that of the existing history entry, the system considers their configurations are the
same and the creation fails.
Table 31 to configure RMON alarm function.
Remarks
Optional
You can create up to 60 event entries for an event table.
An event entry defines event indexes and the actions the system will take, including
log the event, send a trap to the NMS, take no action, and log the event and send
a trap to the NMS.
IMPORTANT:
An entry cannot be created if the values of the specified alarm variable, sampling
interval, sampling type, rising threshold and falling threshold are identical to those of
an existing entry in the system.
