connectivity between the MA5612 and the DHCP server and verifies the DHCP configurations
on a DHCP relay, DHCP proxy, and DHCP server.
Context
l DHCP user configuration is correct.
l An MA5612 initiates DHCP dialup emulation. A PC, set top box (STB), or voice over IP
(VoIP) terminal initiates common DHCP dialup.
l An MA5612 supports a maximum of five DHCP dialup emulation tests at a time.
Procedure
Step 1 Run the simulate dhcp start command to start a DHCP dialup emulation test.
Before running this command, run the service-port command to configure a service port for the
user. Ensure that the service port parameters are the same as those of the actual service.
Otherwise, the emulation fails to start.
Step 2 Run the display simulation dhcp command to query the status of the DHCP dialup emulation.
Only the status of an ongoing DHCP dialup emulation test can be queried. When a DHCP dialup
emulation test is stopped or times out, the resources used by the DHCP dialup emulation are
released and the emulation status cannot be queried. The default emulation timeout period is
210s.
Step 3 Run the simulate dhcp stop command to stop the DHCP dialup emulation test.
----End
Result
The result of the DHCP dialup emulation test is as follows:
Run the display simulation dhcp command to query the status of the DHCP dialup emulation.
