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.
