Nqa Probe Operation Procedure; Nqa Configuration Task List - HP 6125G Configuration Manual

NQA client and server
A device with NQA test groups configured is an NQA client, and the NQA client initiates NQA tests. An
NQA server makes responses to probe packets destined to the specified destination address and port
number.
Figure 37 Relationship between the NQA client and NQA server
Not all test types require the NQA server. Only the TCP, UDP echo, UDP jitter, or voice test requires both
the NQA client and server, as shown in
You can create multiple TCP or UDP listening services on the NQA server. Each listens to a specific
destination address and port number. Make sure the destination IP address and port number for a
listening service on the server are the same as those configured for the test group on the NQA client.
Each listening service must be unique on the NQA server.

NQA probe operation procedure

An NQA probe operation involves the following steps:
The NQA client constructs probe packets for the specified type of NQA test, and sends them to the
1.
peer device.
Upon receiving the probe packets, the peer sends back responses with timestamps.
2.
The NQA client computes the network performance and service quality parameters, such as the
3.
packet loss rate and round-trip time based on the received responses.

NQA configuration task list

Task
Configuring the NQA server
To perform NQA tests successfully, perform the following configurations on the NQA client:
Enable the NQA client.
1.
Create a test group and configure test parameters. The test parameters may vary with test types.
2.
Configure a schedule for the NQA test group.
3.
Complete these tasks to configure NQA client:
