Use the probe count command to configure the number of probes in an NQA test. 

Use the undo probe count command to restore the default. 

By default, one probe is performed in an NQA test. 

z 

For a TCP or DLSw test, one probe means one connection; 

z 

For a UDP-jitter test, the number of packets sent in one probe depends on the probe 

packet-number command; 

z 

For an FTP, HTTP or DHCP test, one probe means to carry out a corresponding function; 

z 

For an ICMP-echo or UDP-echo test, one packet is sent in one probe; 

z 

For an SNMP test, three packets are sent in a probe. 

If the number of probes in a test is greater than 1, the system performs a second probe after it performs 

the first probe and receives a response packet. If the system does not receive a response packet, it 

waits for the test timer to expire before performing a second probe. The process is repeated until the 

specified probes are completed. 

# Configure the number of probes in an ICMP-echo test as 10.

packet-interval: Interval for packets sent in a probe in a UDP-jitter test, in milliseconds, in the range 10 

to 1000. 

Use the probe packet-interval command to configure the interval for sending packets in a probe in a 

UDP-jitter test. 

Use the undo probe-interval command to restore the default. 

By default, the interval is 20 milliseconds.
