The destination port number is configured.
Step 7 (Optional) Perform the following as required to configure other parameters for the Jitter test
( For detailed parameter configurations, see the chapter Configuring Universal NQA Test
Parameters ):
l To configure the VPN instance to be tested, run the vpn-instance vpn-instance-name
command.
NOTE
Only S5700EI and S5700HI support the vpn-instance command.
l To configure the source IP address, run the source-address ipv4 ip-address command.
l To configure the source port number, run the source-port port-numbercommand.
l To configure the probe times in the NQA test, run the probe-count number command.
l To configure the number of test packets sent each time, run the jitter-packetnum number
command.
The Jitter test is used to collect statistics and perform analysis of the transmission delay
variation of the UDP packets. The system sends multiple test packets for each test to make
the statistics more accurate. The more test packets are sent, the more accurate the statistics
and analysis are. This process, however, is time consuming.
NOTE
The number of the Jitter tests depends on the probe-count command. The number of test packets sent
during each test depends on the jitter-packetnum command. During the actual configuration, the
product of the number of test times and the number of the test packets must be less than 3000.
l To configure the interval for sending test packets, run the interval { milliseconds interval |
seconds interval } command.
The shorter the interval for sending the Jitter test packets is, the faster the test is completed.
If the interval, however, is set to a very small value, the jitter statistics result may have a
greater error.
l To configure the percentage of the failed NQA tests, run the fail-percent percent command.
l To send the NQA test packet without searching the routing table, run the sendpacket
passroute command.
Step 8 Run:
start
The NQA test is started.
Select the start mode as required because the start command has several forms.
l To perform the NQA test immediately, run the start now [ end { at [ yyyy/mm/dd ]
hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } } ]
command.
The test instance is started immediately.
l To perform the NQA test at the specified time, run the start at [ yyyy/mm/dd ] hh:mm:ss
[ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime
{ seconds second | hh:mm:ss } } ] command.
The test instance is started at a specified time.
l To perform the NQA test after a certain delay period, run the start delay { seconds second
| hh:mm:ss } [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } |
lifetime { seconds second | hh:mm:ss } } ] command.
