l If a static MAC address is configured on the service port, go to Step 10.3.
l If no static MAC address is configured on the service port, go to Step 11.
3. Run the security anti-macspoofing disable command to disable the anti-MAC address
spoofing function on the service port or run the undo mac-address static command to
delete the static MAC address configured on the port based on the service planning. Then,
perform another dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 11.
Step 11 Check whether an ACL restricting the transmission of PPPoE packets is configured on the
MA5612.
1. Run the display packet-filter port frameid/slotid/portid command to check whether an
ACL is configured on the user port.
l If an ACL is configured, go to Step 11.2.
l If no ACL is configured, go to Step 12.
2. Run the display acl command to check whether the ACL restricts the transmission of
PPPoE packets.
l If the ACL restricts the transmission of PPPoE packets, go to Step 11.3.
l If the ACL does not restrict the transmission of PPPoE packets, go to Step 12.
3. Change the ACL rule that restricts the transmission of PPPoE packets or delete the ACL
configuration on the port. Then, perform another dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 12.
Step 12 Check the data configuration on the upper layer device.
1. Check whether the MTU and QoS configurations on the upper layer device, such as the
upper layer router, are correct.
l If the configurations are correct, go to Step 12.3.
l If the configurations are incorrect, change the settings and ensure that the required data
configurations are correct. Then, go to Step 12.2.
2. Perform a dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 12.3.
3. Check whether the user data configuration on the upper layer BRAS is correct. Check, for
example, whether the user's account is restricted on the BRAS.
l If the data configuration on the BRAS is incorrect or the user's account is restricted,
change the settings on the BRAS. Then, go to Step 12.4.
l If the data configuration on the BRAS is correct and the user's account is not restricted,
go to Step 13.
4. Perform a dialup check.
l If the dialup is successful, go to Step 14.
l If the dialup fails, go to Step 13.
Step 13 Record the results of the preceding steps in a fault report (see Fault Report Form), fill out the
entire form, and then submit it to Huawei for technical support (see Contacting Huawei for
Assistance).
