Supports auto distributing the start time and the test interval when several tests are
performed at a time.
l Supports the auto-delay function, with which the system resources can be effectively
utilized so that tests can be completed within a specified period.
l Supports the collection of the uni-directional delay statistics and bi-directional delay
statistics. In addition, you can set a threshold and enable collecting statistics about the
packets in the test results that exceed the threshold.
l Supports the collection of statistics on packet loss in one direction.
l Supports the flexible alarm mechanism. That is, the upper and lower thresholds are set to
monitor the feature of the tested objects according to their OIDs. When the test result
exceeds the threshold, alarms are triggered based on the preset events.
6.5 Configuring the ICMP Test
This section describes how to configure an Internet Control Message Protocol (ICMP) test to
check the IP network connectivity.
6.5.1 Establishing the Configuration Task
Before configuring an ICMP test, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
An ICMP test has a similar function with the ping command, but its output is more detailed.
Pre-configuration Tasks
Before configuring the ICMP test, configure reachable routes between the NQA client and the
tested device.
Data Preparation
To configure the ICMP test, you need the following data.
No.
Data
1 Administrator name and test name of the NQA test
2 Destination IP address
3 (Optional) Virtual Private Network (VPN) instance name, source interface that sends
test packets, source IP address, size of the Echo-Request packets, TTL value, ToS,
padding character, interval for sending test packets, and percentage of the failed NQA
test
4 Start mode and end mode
