4000 Router Series Network Management and Monitoring Command Reference

trap-only: Specifies the action of displaying results on the terminal display and meanwhile sending

SNMP trap messages to the NMS.

Usage guidelines

You cannot edit a reaction entry after it is created. To change the attributes in a reaction entry, use undo

reaction to delete the entry first and reconfigure a new one.

Only successful probe packets are monitored. Statistics about failed probe packets are not collected.

Examples

# Create reaction entry 1 for monitoring the average destination-to-source jitter of UDP jitter packets,

setting the upper limit to 50 milliseconds and the lower limit to 5 milliseconds. Before the NQA operation

starts, the initial state of the reaction entry is invalid. After the operation, the average

destination-to-source jitter is checked against the threshold range. If it exceeds the upper limit, the state

of the reaction entry is set to over-threshold. If it is below the lower limit, the state is set to below-threshold.

Once the state of the reaction entry changes, a trap message is generated and sent to the NMS.

# Create reaction entry 2 for monitoring the destination-to-source jitter of UDP jitter probe packets,

setting the upper limit to 50 milliseconds, and the lower limit to 5 milliseconds. Before the NQA

operation starts, the initial state of the reaction entry is invalid. After the operation, the

destination-to-source jitter is checked against the threshold range. If the total number of threshold

violations exceeds 100 (included), the state of the entry is set to over-threshold. Otherwise, the state of the

entry is set to below-threshold. Once the state of the reaction entry changes, a trap message is generated

and sent to the NMS.

reaction checked-element mos

Use reaction checked-element mos to configure a reaction entry for monitoring the MOS value in the

voice operation.

Use undo reaction to delete the specified reaction entry.

Syntax

[ action-type { none | trap-only } ]

undo reaction item-number

Default

No reaction entry for monitoring the MOS value is configured.
