HUAWEI NetEngine80E/40E Router
Configuration Guide - IP Routing
An ICMP NQA test instance is used to check whether a route from the NQA client to the
destination is reachable. The ICMP test provides functions similar to the ping command except
that more information is output.

An Internet Control Messages Protocol (ICMP) NQA test instance sends packets at a minimum
interval of 1 second. This ensures that NQA reports the test results to the system when a link
fault is detected and when the link fault is rectified. For details about NQA configurations, see
the section "NQA Configuration" in HUAWEI NetEngine80E/40E Router Configuration Guide
- SystemManagement.
Perform the following steps on the NQA client:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nqa test-instance admin-name test-name
An NQA test instance is created, and the test instance view is displayed.
Step 3 Run:
test-type icmp
The test type is set to ICMP.
Step 4 Run:
destination-address ipv6 ipv6-address
The destination address is set.
In an NQA test instance, you can specify an NQA server by running the destination-address
command to specify a destination address for an NQA test instance.
Step 5 (Optional) Run:
frequency interval
The interval for automatically performing an NQA test is set. By default, no automatic test
interval is set. The system performs the test only once.
Step 6 (Optional) Run:
probe-count number
The number of probes to be sent each time is set for the NQA test instance. By default, the
number is 3.
By sending probes multiple times for an NQA test instance, you can estimate the network quality
more accurately based on the collected statistics.
Step 7 Run:
start
Issue 02 (2014-09-30)
By default, the output contains the results of the latest five tests.
The output includes the average delay, the packet loss ratio, and the time the last packet is
correctly received.
