jitter-packetnum

Function

The jitter-packetnum command sets the number of packets sent in each probe test instance.

The undo jitter-packetnum command restores the default number of packets sent in each probe test instance.

By default, 20 test packets are sent in each probe.

Format

jitter-packetnum number

undo jitter-packetnum

Parameters

Parameter	Description	Value
number	Specifies the number of test packets sent in each probe in the jitter test (probe-count).	The value is an integer that ranges from 1 to 3000. The default value is 20.

Usage Guidelines

Usage Scenario

In an NQA test instance, the jitter-packetnum command can be used to set the number of consecutive packets to simulate the actual traffic of a data in a specified period of time. This helps simulate services more accurately.

For example, the jitter-packetnum command can be used to set the number of consecutive packets to 3000 and an interval of 20 ms to send packets. In this way, G.711 traffic can be simulated within one minute to detect VoIP services in UDP jitter test instances.

Prerequisites

The type of a test instance has been specified using the test-type command. The number of sent packets can be configured only for UDP Jitter, LSP jitter, Path Jitter, and ICMP Jitter test instances.

Configuration Impact

In UDP Jitter, LSP jitter, Path Jitter, and ICMP Jitter test instances, the number of sent packets = jitter-packetnum x probe-count, but the product cannot exceed 3000.
If the number of probe packets has been set, running the jitter-packetnum command will override the previous configuration.

Precautions

The number of probe packets of a running test instance cannot be changed.

Example

# Perform 3 probes in the test named user test and send 1000 packets in each probe.
