NQA C
ONFIGURATION
Introduction to NQA
NQA, which is an enhancement of the ping function, is used to test the 
performance of various protocols operating in the network.The ping function can 
only use the ICMP protocol to test the round trip travel time of data packets 
between the local endpoint and the specified destination endpoint by command 
lines. While the NQA not only can finish the above functions, but also can probe 
whether the DLSW, DHCP, FTP, HTTP, and SNMP servers are on or off, and test the 
response time of various services. Besides, the NQA also realizes the MIB operation 
through which you can perform various tests conveniently.
The ICMP function test of NQA has the following features:
The NQA function is similar with the ping function. But the NQA has more 
parameters and can execute multiple tests simultaneously and automatically.
The NQA function configures various parameters needed by the test through the 
network management tool or the command line. Then you can enable the test, 
and view the test result. After the test, use the display nqa command to display 
the test result.
The ICMP function of NQA and the corresponding MIB operation of the ICMP are 
realized on the Switch 8800 Family switch. Other functions, like DLSW, DHCP, FTP, 
HTTP and SNMP are not realized on the Switch 8800 Family switch at present.
NQA Configuration
The ICMP function test of the NQA includes the following configuration:
Enable the NQA client function.
Configure the maximum number of the test tasks that can be performed 
simultaneously.
Set the NQA test group.
Set various test parameters.
Enable the test.
Display the test result.
Configuration 
Prerequisites
The ICMP function of the NQA needs no special prerequisite; however, note the 
following two points during the configuration:
Enabling the NQA client function is the prerequisite of all tests.
To execute the test, you must set the NQA test group, configure the 
parameters, and then enable the test.
