Configuring Trap Delivery 

Traps can be sent to the network management server when test is completed, test fails or probe fails. 

Configuration prerequisites 

Before configuring trap delivery, you need to configure the destination address of the trap message with 

the snmp-agent target-host command, create an NQA test group, and configure related parameters. 

For the introduction to the snmp-agent target-host command, refer to SNMP Commands in the 

System Volume. 

Configuring trap delivery 

Follow these steps to configure trap delivery: 

Enter system view 

system-view 

— 

Enter NQA test group view 

nqa entry admin-name 
operation-tag 

— 

Enter test type view of the 
test group 

type { dhcp | dlsw | dns | ftp | 
http | icmp-echo | snmp | tcp | 
udp-echo | udp-jitter | voice } 

— 

Configure to send traps to 
network management server 
under specified conditions 

{ 

probe-failure 

consecutive-probe-failures | 
test-complete | test-failure 
cumulate-probe-failures } 

Optional 

No traps are sent to the network 
management server by default. 

 

Only the reaction trap test-complete command is supported in a voice test, namely, in a voice test, 

traps are sent to the NMS only if the test succeeds. 

 

NQA puts the NQA tests completed in a specified interval into one group, and calculates the statistics of 

the test results of the group. These statistics form a statistics group. You can use the display nqa 

statistics command to view information of the statistics group, and use the statistics interval 

command to set the interval for collecting statistics. 

When the number of statistics groups kept reaches the upper limit, if a new statistics group is generated, 

the statistics group that is kept for the longest time is deleted. You can use the statistics max-group 

command to set the maximum number of statistics groups that can be kept. 

A statistics group is formed after the last test is completed within the specified interval. A statistics group 

has the aging mechanism. A statistics group will be deleted after it is kept for a period of time. You can 

use the statistics hold-time command to set the hold time of a statistics group. 

Follow these steps to configure the NQA statistics function:
