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 15.
l If the dialup fails, go to Step 14.
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.
l If the dialup is successful, go to Step 15.
l If the dialup fails, go to Step 14.
7. In ETH mode, run the display port state portid command to check whether the duplex
mode, rate, network cable adaptation mode of the Ethernet port are consistent with those
of the user terminal.
l If they are consistent, go to Step 3.9.
l If they are inconsistent, modify the parameter settings of the Ethernet port to ensure that
the parameter settings are consistent with those of the user terminal. Then, go to Step
3.8.
NOTE
In ETH mode, modify the parameter settings of the Ethernet port by using the following methods:
l Run the auto-neg command to enable or disable the auto-negotiation mode of the Ethernet port.
After the auto-negotiation mode of the Ethernet port is enabled, the Ethernet port automatically
negotiates the port rate and duplex mode with the interconnected port.
l Run the duplex command to configure the duplex mode of the Ethernet port to full duplex or half
duplex.
l Run the mdi command to configure the network cable adaptation mode of the Ethernet port.
l Run the speed command to configure the rate of the Ethernet port.
8. Perform a dialup check.
l If the dialup is successful, go to Step 15.
