DHCP Tests

The DHCP test monitors the amount of time required to send a DHCP request and receive a response.

Note: Run DHCP tests only for systems that are statically configured and are not running a DHCP client. These tests require an open socket on port 68 to listen for requests. If another process (such as a DHCP client) is already listening on port 68, the test will fail.

Options and Arguments

DHCP tests require only the following options and arguments:

DHCP Server – The hostname or IP address of the DHCP server to test. Specify this argument when you create or modify tests.

Note: IPv6 addresses can be used, but they must be embedded in brackets, for example [0:0:0:0:0:0:10.0.00.0].

Example

Use this example to create a test that monitors the amount of time that is required to send a DHCP request to the DHCP server and receive a response.
