Configuring the DHCP
Test
The 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
The interface specified by the source-interface command must be up.
Before the DHCP test, you need to perform some configurations on the DHCP
server. For example, you need to enable the DHCP service and configure an
address pool. If the NQA (DHCP) client and the DHCP server are not in the same
network segment, you need to configure a DHCP relay. For detailed
configurations, refer to
“DHCP Server Configuration” on page 721.
Configuration procedure
Follow these steps to configure the DHCP test
Configuration example
1 Network requirements

address from the DHCP server Switch B.
