Configuring the NQA server
Required for TCP, UDP echo, UDP jitter, and
voice operations.
(Required.) Enabling the NQA client N/A
(Required.) Perform at least one of the following tasks:
• Configuring NQA operations on the NQA client
• Configuring NQA templates on the NQA client
When you configure
analyze network performance, the feature
that uses the template performs the NQA
operation.
Configuring the NQA server
To perform TCP, UDP echo, UDP jitter, and voice operations, you must enable the NQA server on the
destination device. The NQA server listens and responds to requests on the specified IP addresses
and ports.
You can configure multiple TCP or UDP listening services on an NQA server, where each
corresponds to a specific IP address and port number. The IP address and port number for a
listening service must be unique on the NQA server and match the configuration on the NQA client.
To configure the NQA server:
1. Enter system view.
system-view
N/A
2. Enable the NQA server.

server is disabled.
3. Configure a
listening service.
• TCP listening service:
