Operation Manual – NQAH3C S9500 Series Routing Switches Chapter 1 NQA Configuration1-1Chapter 1 NQA ConfigurationWhen configuring NQA, go to these sections for information you are interested in:z Introduction to NQAz NQA Configurationz Displaying and Maintaining NQA1.1 Introduction to NQAA network quality analyzer (NQA), which is an enhancement of the ping function, isused to test the performance of various protocols operating in a network. The pingfunction can only use ICMP to test the round trip travel time of data packets betweenthe local endpoint and the specified destination endpoint by command lines, While NQAon the S9500 series switches can finish not only the above functions, but also the ICMPfunction and the MIB operation corresponding to ICMP. Other functions such as DLSw,DHCP, FTP, HTTP, and SNMP are not implemented yet.The ICMP function test of NQA has the following features:The NQA function is similar with the ping function. But NQA has more parameters andcan execute multiple tests simultaneously and automatically, and collect and save testresults.The NQA function configures various parameters needed by the test through thenetwork management tool or the command line. Then you can enable the test, andview the test result. After the test, use the display nqa results command to display thetest result.1.2 NQA ConfigurationThe ICMP function test of NQA includes the following configuration:z Enable the NQA client function.z Configure the maximum number of the test tasks that can be performedsimultaneously.z Set the NQA test group.z Set various test parameters.z Enable the test.z Display the test result.1.2.1 Configuration PrerequisitesThe ICMP function of NQA needs no special prerequisite; however, note the followingtwo points during the configuration:
