Remarks
Configuring the NQA server
Required for TCP, UDP echo, UDP jitter, and
voice operations.
(Required.) Use one of the following methods:
• Configure NQA operations:
{ Enabling the NQA client
{ Configuring NQA operations on the NQA client
{ Scheduling the NQA operation on the NQA client
• Configuring NQA templates on the NQA client
When you configure an NQA template to
analyze network performance, the feature
that uses the template starts 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. A listening service must be unique on the NQA server, and its IP
address and port number must be the same as those configured on the NQA client.
To configure the NQA server:
