Specify an interface to perform DHCP tests. operation interface interface-type interface-number By default, no interface is configured to perform DHCP tests. The specified interface must be up; otherwise, no probe packets can be sent out. 5. Configure optional parameters. See Configuring optional parameters for an NQA test group Optional. Configuring DNS tests DNS tests of an NQA test group are used to test whether the NQA client can translate a domain name into an IP address through a DNS server and test the time required for resolution. Before you start DNS tests, configure the mapping between a domain name and an IP address on a DNS server. A DNS test simulates the domain name resolution. It does not save the mapping between the domain name and the IP address. To c o n fig u re D NS tes t s : Step Command Remarks 1. Enter system view. system-view N/A 2.

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 you configure FTP tests:
• When you execute the put command, the NQA client creates a file named file -name of fixed size
on the FTP server. The file -name argument does not represent any file on the NQA client. When you
execute the get command, the client does not save the files obtained from the FTP server.
• When you get a file that does not exist on the FTP server, FTP tests fail.
• When you perform an FTP test, use a small file and set a long NQA probe timeout time. A big file
or short probe timeout time may result in probe timeout.

Configuring UDP jitter tests
113 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 source sends packets to the destination port at regular intervals. 2. The destination affixes a time stamp to each packe t that it receives, and then sends the packet back to the source. 3. Upon receiving the response, the source calculates the delay jitter, which reflects network performance. Delay refers to the amount of time it takes a packet to be transmitted from source to destination or from destination to source. De lay jitter is the delay variation over time. Configuration prerequisites UDP jitter tests require cooperation between the NQA server and the NQA client. Before you start UDP jitter tests, configure UDP listening services on the NQA server. For more information about UDP listening service configuration, see Configuring the NQA server . Configuration procedure To configure UDP jitter tests: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter NQA test group view. nqa entry admin-name operation-tag N/A 3. Configure the test type as UDP jitter, and enter test type view. type udp-jitter N/A 4. Configure the destination address of UDP packets. destination ip ip-address By default, no destination IP address is configured. The destination IP address must be the same as that of the listening service on the NQA server. 5.

The destination port must be the same as that of the listening servic e on the NQA server. 6. Specify the source port number of UDP packets. source port port-number Optional. By default, no source port number is specified. 7. Configure the size of the data field in each UDP packet. data-size size Optional. 100 bytes by default. 8.

Configure the source IP address for UDP jitter 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. 13. Configure optional parameters. See Configuring optional parameters for an NQA test group Optional. NOTE: The probe count command specifies the number of probe op erations during one UDP jitter test. The probe packet-number command specifies the number of probe packets sent in each UDP jitter probe operation. Configuring SNMP tests SNMP tests of an NQA test group are used to test the time the NQA client takes to send an SNMP packet to the SNMP agent and receive a response.

116 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.

See Configuring opti onal parameters for an NQA test group Optional. Configuring voice tests IMPORTANT:
117 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 intervals to the destination (NQA server). 2. The destination affixes a time stamp to each voice packet that it receives and then sends it back to the source. 3. Upon receiving the packet, the source calculates results, such as the delay jitter and one-way delay based on the packet time stamps. The st atistics reflect network performance. Voice test result also includes the following par ameters that reflect VoIP network performance: • Calculated Planning Impairment Factor (ICPIF)—Me asures impairment to voice quality in a VoIP network. It is decided by packet loss and delay. A higher value represents a lower service quality. • Mean Opinion Scores (MOS)—A MOS value can be evaluated by using the ICPIF value, in the range of 1 to 5. A higher value represents a higher quality of a VoIP network. The evaluation of voice quality depends on users’ tole rance for voice quality, which should be taken into consideration. For users with higher tolerance for voice quality, use the advantage-factor command to configure the advantage factor. When the system calculates the ICPIF value, this advantage factor is subtracted to modify ICPIF and MOS values, so objective and subjective factors are both considered when you evaluate voice quality. Configuration prerequisites • Voice tests require cooperation between the NQA server and the NQA client. Before you start voice tests, configure a UDP listening service on the NQA server. For more information about UDP listening service configuration, see Configuring the NQA server. • Onl y one probe operation is performed in one voice test. Configuration procedure To configure voice tests: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter NQA test group view. nqa entry admin-name operation-tag N/A 3.
