H3C SR6600 Command Reference Manual page 62

Default
No reaction entry for monitoring packet round-trip time is configured.
Views
UDP jitter operation view, voice operation view
Default command level
2: System level
Parameters
item-number: Specifies a reaction entry ID in the range of 1 to 10.
threshold-type: Specifies a threshold type.
accumulate accumulate-occurrences: Specifies the total number of threshold violations. The value is in the
range of 1 to 15000 for UDP jitter operation and 1 to 60000 for voice operation.
average: Specifies to check the packet average round-trip time.
threshold-value: Specifies threshold values in milliseconds.
upper-threshold: Specifies the upper threshold in the range of 0 to 3600000.
lower-threshold: Specifies the lower threshold in the range of 0 to 3600000. It must not be greater than
the upper threshold.
action-type: Specifies what action to be triggered. The default action is none.
none: Specifies the action of only displaying results on the terminal display.
trap-only: Specifies the action of displaying results on the terminal display and meanwhile sending
SNMP trap messages to the NMS.
Usage guidelines
Only successful probe packets are monitored. Failed probe packets are not counted.
Examples
# Create reaction entry 1 for monitoring the average round-trip time of UDP jitter probe packets. Set the
upper threshold to 50 milliseconds and lower threshold to 5 milliseconds. Before the NQA operation
starts, the initial state of the reaction entry is invalid. After the operation, the average packet round-rip
time is checked. If it exceeds the upper threshold, the state is set to over-threshold. If it is below the lower
threshold, the state is set to below-threshold. Once the reaction entry state changes, a trap message is
generated and sent to the NMS.

# Create reaction entry 2 for monitoring the round-trip time of UDP jitter probe packets. Set the upper
threshold to 50 milliseconds, and lower threshold to 5 milliseconds. Before the NQA operation starts, the
initial state of the reaction entry is invalid. After the operation, the packet round-trip time is checked. 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.
