Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
nqa test-instance admin-name test-name
An NQA test instance is created and the test instance view is displayed.
Step 3 Run:
test-type icmpjitter
The type of the test instance is configured as ICMP jitter.
Step 4 Run:
destination-address ipv4 ip-address
The destination IP address is configured.
Step 5 (Optional) Run the following commands to configure other parameters for the jitter test:
l Run:
icmp-jitter-mode { icmp-echo | icmp-timestamp }
The mode of the ICMP jitter test is configured.
l Run:
vpn-instance vpn-instance-name
The VPN instance to be tested is configured.
NOTE
Only the S5700HI and S5706LI support this parameter.
l Run:
probe-count number
The number of test probes to be sent each time is set.
l Run:
jitter-packetnum number
The number of test packets to be sent during each test is set.
NOTE
The probe-count command is used to configure the number of times for the jitter test and the jitter-
packetnum command is used to configure the number of test packets to be sent during each test. In
actual configuration, the product of the number of times for the jitter test multiplied by the number of
test packets must be less than 3000.
l Run:
interval { milliseconds interval }
The interval for sending test packets is set.
The shorter the interval is, the sooner the test is complete. However, delays arise from sending
and receiving test packets on the processor. Therefore, if the interval for sending test packets
is set to a small value, a relatively greater error may occur in the statistics of the jitter test.
l Run:
fail-percent percent
