Configuring a DHCP Test
A DHCP test is mainly used to test the existence of a DHCP server on the network as well as the time
necessary for the DHCP server to respond to a client request and assign an IP address to the client.
Configuration prerequisites
Before performing a DHCP test, configure the DHCP server. If the NQA (DHCP client) and the DHCP
server are not in the same network segment, configure a DHCP relay. For the configuration of DHCP
server and DHCP relay, see DHCP Server Configuration and DHCP Relay Agent Configuration in the
Layer 3 - IP Services Configuration Guide.
Configuring a DHCP test
Follow these steps to configure a DHCP test:

Required
By default, no interface is specified
to perform a DHCP test.
The interface specified by the
source interface command must
be up; otherwise, the test fails.

z Because a DHCP test is a process to simulate address allocation in DHCP, the IP address of the
interface that performs the DHCP test does not change.
z When the DHCP test is completed, the NQA client sends a DHCP-RELEASE packet to release
the obtained IP address.
Configuring a DNS Test
A DNS test is mainly used to test whether the NQA client can resolve a domain name into an IP
address through a DNS server and the time required for resolution.
