15.4.2.10 Verifying Services
A distributed cable modem termination system (D-CMTS) working as a remote extended frame
locates on an optical node. To facilitate service verification, the optical line terminal (OLT)
supports multiple remote service verification methods, such as Dynamic Host Configuration
Protocol (DHCP) dialup emulation tests. This allows commissioning and configuration
engineers to remotely verify services. In addition, this section describes how to verify the L2VPN
service on site.
Prerequisites
l The OLT is properly connected to the upper-layer network.
l The DHCP server, Trivial File Transfer Protocol (TFTP) server, and softswitch or IP
multimedia subsystem (IMS) have been configured.
Procedure
l Perform a DHCP dialup emulation test.
In this test, a cable modem (CM) is emulated on the OLT to apply to the DHCP server for
an IP address. This checks whether the OLT can communicate with the DHCP server and
verifies CM DHCP configurations on the DHCP relay, proxy, and server.
1. Run the simulate dhcp start cm mac-address [ option60 option60 ] command to start
a DHCP dialup emulation test.
NOTE
You can run the simulate dhcp stop command to stop the DHCP emulation.
2. Run the display simulation dhcp command to query the results of the DHCP dialup
emulation test.
3. Check whether the User IP has obtained an IP address.
l Check the CM status.
Run the display cable modem command to query the CM status in Status.
