Configuring FTP tests 
FTP tests of an NQA test group are used to test the connection between the NQA client and an FTP server 
and the time required for the FTP client to transfer  a file to or download a file from the FTP server. 
Before you start FTP tests, configure the FTP server. For example, configure a username and password that 
are used to log in to the FTP server. For more information about FTP server configuration, see 
Fundamentals Configuration Guide . 
Follow these guidelines when...

Step Command Remarks 
11. Configure optional 
parameters.  See 
Configuring optional 
parameters for an NQA 
test group   Optional.
 
 
Configuring HTTP tests 
HTTP tests of an NQA test group are used to test the connection between the NQA client and an HTTP 
server, and the time required to obtain data from the HTTP server. HTTP tests enable you to detect the 
connectivity and performance of the HTTP server. The TCP port must be port 80 on the HTTP server for 
NQA HTTP tests. 
Before you start...

 IMPORTANT: 
Do not perform NQA UDP jitter tests on known ports, 
ports from 1 to 1023. Otherwise, UDP jitter tests 
might fail or the corresponding services  of this port might be unavailable. 
 
Real-time services such as voice and video have high requirements on delay jitters. UDP jitter tests of an 
NQA test group obtain uni/bi-directional delay jitters. The test results help you verify whether a network 
can carry real-time services. 
A UDP jitter test performs the following procedure: 
1. The...

9.  Configure the number of 
probe packets to be sent 
during each UDP jitter probe 
operation.  probe packet-number

 Configure the interval for 
sending probe packets during 
each UDP jitter probe 
operation.  probe packet-interval 
packet-interval
 Optional. 
20 milliseconds by default.

Step Command Remarks 
5.  Specify the source port 
of SNMP packets.  source port 
port-number  Optional. 
By default, no source port number is specified.
 
6.
  Configure the source IP 
address of SNMP 
packets.  source ip ip-address
 Optional. 
By default, no source IP address is specified. 
The source IP address must be the IP address of 
a local interface. The local interface must be up; 
otherwise, no probe packets can be sent out. 
7.
  Configure optional 
parameters.  See

Configuring UDP echo tests 
UDP echo tests of an NQA test group are used to test the connectivity and round-trip time of a UDP packet 
from the client to the specified UDP port on the NQA server. 
UDP echo tests require cooperation between the NQA server and the NQA client. Before you start UDP 
echo tests, configure a UDP listening service on the NQA server. For more information about the UDP 
listening service configuration, see  Configuring the NQA server.

Do not perform voice tests on known ports, ports from 1 to 1023. Otherwise, the NQA test might fail or the
corresponding services of thes e ports might be unavailable. 
 
Voice tests of an NQA test group are used to test voice over IP (VoIP) network status, and collect VoIP 
network parameters so that users can adjust the network.  
A voice test performs the following procedure: 
1. The source (NQA client) sends voic e packets of G.711 A-law, G.711 μ-law or G.729 A-law 
codec type at regular...

Step Command Remarks 
5.  Configure the destination 
port of voice probe 
packets.  destination port 
port-number
 
By default, no destination port number is 
configured. 
The destination port must be the same as that 
of the listening servic e on the NQA server. 
6.  Configure the codec type.  codec-type 
{ g711a  | g711u 
|  g729a  }  Optional. 
By default, the codec type is G.711 A-law.

factor for calculating MOS 
and ICPIF values.  advantage-factor
