Procedure
Step 1 Perform a 8.9 PPPoE Dialup Emulation Test on the MA5612 for the affected user.
l If the result of the dialup emulation test is not "success," go to Step 4.
NOTE
If the result of the dialup emulation test is "timeout," "parameter negotiation failure," "user authentication
failure," "offline requested by the peer end," or other errors, the fault is located on the upper layer device
of the MA5612.
l If the result of the dialup emulation test is "success," go to Step 2.
Step 2 Check the user terminal.
1. Replace the user's PC with another and perform a dialup emulation test to check whether
the dialup can be successful.
l If the dialup is successful, the fault is related to a problem on the user's PC. Check
whether the PPPoE software is installed on the PC incorrectly and whether the PC's NIC
is faulty or disabled, and address the problem. Then, go to Step 14.
l If the dialup fails, go to Step 2.2.
2. Replace the user's terminal and perform a dialup check. Then, check whether the dialup is
successful.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 3.
Step 3 Check the interoperability between the user terminal and the MA5612.
1. In ETH mode, run the display port state portid command on the MA5612 to check whether
Active State of the Ethernet port is active.
l If Active State of the Ethernet port is active, go to Step 3.3.
l If Active State of the Ethernet port is not active, go to Step 3.2.
2. Run the undo shutdown portid command to activate the Ethernet port. Then, check
whether it is in the active state.
l If it is in the active state, go to Step 3.3.
l If it is not in the active state, go to Step 3.9.
3. Run the display port state portid command to check whether Link of the Ethernet port is
online.
l If Link of the Ethernet port is online, go to Step 3.4.
l If Link of the Ethernet port is not online, go to Step 3.5.
4. Perform a dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 13.
5. Check the quality of the physical line between the MA5612 and the user terminal to
determine whether the line is not connected properly or the line is old. Reconnect the line
properly or replace the old line as needed to ensure good line quality. Then, check whether
Link of the Ethernet port is online.
l If Link of the Ethernet port is online, go to Step 3.6.
l If Link of the Ethernet port is not online, go to Step 3.7.
6. Perform a dialup check.
