Default
In an UDP tracert operation, the NQA client sends three probe packets to each hop along the path.
In other types of operations, the NQA client performs one probe to the destination per operation.

Parameters
times: Specifies the probe times.
•
For the UDP tracert operation, this argument specifies the times of probes to each hop along
the path. The value range for this argument is 1 to 10.
•
For other types of operations, this argument specifies the times of probes to the destination per
operation. The value range for this argument is 1 to 15.
Usage guidelines
The following describes how NQA performs different types of operations:
•
A TCP or DLSw operation sets up a connection.
•
An ICMP jitter or UDP jitter operation sends a number of probe packets. The number of probe
packets is set by using the probe packet-number command.
•
An FTP operation uploads or downloads a file.
•
An HTTP operation gets a Web page.
•
A DHCP operation gets an IP address through DHCP.
•
A DNS operation translates a domain name to an IP address.
•
An ICMP echo sends an ICMP echo request.
•
A UDP echo operation sends a UDP packet.
•
An SNMP operation sends one SNMPv1 packet, one SNMPv2c packet, and one SNMPv3
packet.
•
A UDP tracert operation determines the routing path from the source to the destination. The
number of probe packets sent to each hop is set by using the probe count command.
•
A frame loss, latency, or throughput operation sends probe frames to the destination device to
test the frame loss ratio, latency, or throughput of the network.
If an operation is to perform multiple probes, the NQA client starts a new probe in one of the following
conditions:
•
The NQA client receives responses to packets sent in the last probe.
•
The probe timeout time expires.
