24 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting Common service problems in MA5300: User cannot find the PPPoE server. Username or password is incorrect. Low speed.

25 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting User cannot find the PPPoE server. Cause: The PPPoE client cannot find the PPPoE server. Locating problem: Physical layer, or data link layer. Solving problems: [User] Check the PPPoE client was installed correctly; Check the Physical connection between computer and modem, modem and the phone line; Check modem was configured correctly;

26 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting [DSLAM] Check the EAD board state, and the ADSL line state; Check the connection between DLSAM and BAS; Check the vpi/vci of the ADSL port; Check the VLAN configuration in DSLAM; ADSL port and uplink ethernet port. [BAS] Check the PPPoE configuration in BAS. Virtual-template and whether the port is bound with VT.

27 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting Username or password is incorrect. Cause: user cannot pass authentication. Locating problem: PPP link layer, network layer. Physical layer works. Physical layer is working normally. Solving problems: [User] Confirm the user input correct username and password; [BAS] Check the authentication configuration in BAS, whether the user uses local authentication or Radius authentication.

28 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting If the user uses local authentication, check whether this username and password was configured in the BAS correctly. If the user uses Radius authentication, check the Radius configuration. [External equipment] Check the Radius server is working normally, and is reachable. Check the username and password was configured in the Radius correctly.

29 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting Low speed. Solving problems: [User] Check the user’s computer’s hardware configuration, and running performance. Check the cable and line is fully connected. [DSLAM] Check the quality of the ADSL line Check the transmission rate configuration of the ADSL line profile.

30 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal PPPoE Service Troubleshooting [BAS] Check the CAR configuration of the user. Ping destination IP address to see whether there is a traffic bottleneck to the destination in network. If possible, connect a server directly with BAS, observe the traffic on the user’s computer.

31 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal DHCP Service Troubleshooting User cannot obtain IP address. Locating problem: physical layer, data link layer, network layer. Solving problem: [User]: Check the IP configuration of the computer. Check the Physical connection between computer and modem, modem and the phone line; Check modem was configured correctly;

32 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal DHCP Service Troubleshooting [DSLAM] Check the EAD board state, and the ADSL line state; Check the connection between DLSAM and BAS; Check the vpi/vci of the ADSL port; Check the VLAN configuration in DSLAM; [BAS] Check the service configuration. If the external DHCP is used, check the DHCP server is working normally and reachable.

33 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal DHCP Service Troubleshooting [External equipment] Make sure the configuration in DHCP server is correct.

34 Confidential Information of Huawei. No Spreading without Permission. Security Level: Internal DHCP Service Troubleshooting Low speed. Same as PPPoE service.
