Configuring threshold monitoring 
Configuration prerequisites 
Before you configure threshold monitoring, complete the following tasks: 
•  Configure the destination address of the trap message by using the  snmp-agent target-host 
command. For more information about the  snmp-agent target-host command, see Network 
Management and Monitoring Command Reference . 
•   Create an NQA test group and configure the related parameters.

Step Command Remarks 
4.  Configure 
threshold 
monitoring. 
• Enable  sending traps to the netw ork management server 
under specified conditions:  
reaction trap  { probe-failure  consecutive-probe-failures  | 
test-complete  | test-failure  cumulate-probe-failures  } 
• Configure a reaction entry for monitoring the probe duration 
of a test (not supported in UDP jitter and voice tests):  
reaction  item-number  checked-element probe-duration 
threshold-type  { accumulate  accumulate-occurrences...

Configuring the NQA statistics collection function 
NQA groups tests completed in a time period for a test group, and calculates the test result statistics. The 
statistics form a statistics group. To view information about the statistics groups, use the display nqa 
statistics  command. To set the interval for collecting statistics, use the  statistics interval command. 
When the number of statistics groups kept reaches  the upper limit and a new statistics group is to be 
saved, the oldest...

  Enable the saving of the 
history records of the 
NQA test group.  history-record enable 
By default, history records of the NQA test 
group are not saved.

Step Command Remarks 
5.  Configure the interval between 
two consecutive tests for a test 
group.  frequency
 interval  Optional. 
By default, the interval between two 
consecutive tests for a test group is 0 
milliseconds. Only one test is performed. 
If the last test is not completed when the 
interval specified by the
 frequency 
command is reached, a new test does not 
start. 
6.   Configure the number of probe 
operations to be performed in 
one test.  probe count times
 Optional.

Configuration guidelines 
Follow these guidelines when you schedule an NQA test group: 
•  After an NQA test group is scheduled, you cannot  enter the test group view or test type view. 
•   System adjustment does not affect st arted or completed test groups. It only affects test groups that 
have not started. 
Configuration procedure 
To schedule an NQA test group:  
Step Command Remarks 
1.   Enter system view.

2.  Configure a schedule 
for an NQA test 
group.  nqa schedule...

NQA configuration examples 
ICMP echo test configuration example 
Network requirements 
As shown in  Figure 40, c onfigure NQA ICMP echo tests to test whether the NQA client (Device A) can 
send packets through a specific next hop to the spec ified destination (Device B) and test the round-trip 
time of the packets.

Configuration procedure 
Before you make the configuration, make sure the devices can reach each other. 
# Create an ICMP echo test group, and specify...

DNS test configuration example 
Network requirements 
As shown in  Figure 42, c onfigure NQA DNS tests to test whether Device A can translate the domain 
name  host.com into an IP address through the DNS server and test the time required for resolution.
