l If the dialup fails, go to Step 5.
Step 5 Check the PITP configuration on the MA5612.
1. Run the display pitp config command to check whether the current global PITP function
is enabled.
l If the function is enabled, go to Step 5.2.
l If the function is not enabled, go to Step 6.
2. Run the display pitp config command to check the current PITP mode.
l If the current PITP mode is pmode, go to Step 5.5.
l If the current PITP mode is vmode, go to Step 5.3.
3. Run the display pitp vmode ether-type command to query the currently configured
Ethernet protocol type in the VBRAS packet and check whether the protocol type is the
same as the protocol type configured on the upper layer device.
l If the protocol types are the same, go to Step 6.
l If the protocol types are different, go to Step 5.4.
4. Run the pitp vmode ether-type command to change the current protocol type so it is the
same as the protocol type configured on the upper layer device, and then perform another
dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 6.
5. Run the display pitp permit-forwarding service-port service-portid command to check
whether the function that allows user-side PPPoE packets to carry vendor tags is enabled
on the service port of the affected user.
l If the function is enabled, go to Step 6.
l If the function is not enabled, run the pitp permit-forwarding service-port service-
portid enable command to enable it on the service port. Then, go to Step 5.6.
6. Perform a dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 6.
Step 6 Check the user port MAC address configuration on the MA5612.
1. Run the display mac-address port frameid/slotid/portid command to query the current
number of MAC addresses learned by the service port of the user.
2. Run the display mac-address max-mac-count service-port index command to query the
maximum number of MAC addresses that can be learned by the service port.
3. Check whether the current number of MAC addresses learned by the service port reaches
the maximum number of MAC addresses that can be learned by the service port.
l If the current number has reached the maximum number, run the mac-address max-
mac-count service-port index command to increase the maximum number of MAC
addresses that can be dynamically learned by the service port. Then, go to Step 7.
l If the maximum number has not been reached, go to Step 8.
Step 7 Perform a dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 8.
