Configuring DHCP tests
DHCP tests of an NQA test group are used to test if a DHCP server is on the network, and how long it
takes for the DHCP server to respond to a client request and assign an IP address to the client.
Configuration prerequisites
Before you start DHCP tests, 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 Layer 3—IP Services Configuration Guide.
Configuring DHCP tests
To configure DHCP tests:
Step Command
Remarks
1.
Enter system view.
system-view N/A
2.
Enter NQA test group view.
nqa entry admin-name
operation-tag
N/A
3.
Configure the test type as
DHCP and enter test type
view.
type dhcp N/A
4.
Specify an interface to
perform DHCP tests.
operation interface interface-type
interface-number
By default, no interface is
configured to perform DHCP tests.
The specified interface must be up;
otherwise, no probe packets can
be sent out.
5.
Configure optional
parameters.
See “
parameters for an NQA test
group
Optional.
NOTE:
•
The interface that performs DHCP tests does not change its IP address. A DHCP test only simulates
address allocation in DHCP.
•
When a DHCP test completes, the NQA client sends a DHCP-RELEASE packet to release the obtained IP
address.
Configuring DNS tests
DNS tests of an NQA test group are used to test whether the NQA client can translate a domain name
into an IP address through a DNS server and test the time required for resolution.
Configuration prerequisites
Before you start DNS tests, configure the mapping between a domain name and an IP address on a DNS
server.
