Configuring a DNS Test Instance

Before configuring a DNS test instance, configure a DNS server and ensure reachable routes between the DNS client and the DNS server.

A DNS test can detect the speed at which a DNS name is resolved into an IP address.

The NQA client also functions as the DHCP client. Perform the following steps on the NQA client.

Run system-view
The system view is displayed.
Run dns resolve
Dynamic DNS resolution is enabled.

By default, dynamic DNS resolution is disabled.
Run nqa test-instance admin-name test-name
An NQA test instance is created, and the NQA view is displayed.
Run test-type dns
The test type is set to DNS.
Run dns-server ipv4 ip-address
The DNS server address is configured.
Run destination-address url urlstring
The name of the destination host is configured.
