Users on a 3G Cellular Interface Fails to Be Authenticated Because the Authentication Configuration Is Incorrect

Users on a 3G Cellular Interface Fails to Be Authenticated Because the Authentication Configuration Is Incorrect

Fault Symptom

When using 3G cellular interfaces to access the Internet through dial-up, users fail to be authenticated on an external PDN.

Fault Analysis

The possible causes are as follows:

  1. The authentication mode configured using the user command in the APN profile view is inconsistent with the authentication mode provided by the carrier.
  2. The user name and password configured using the user command in the APN profile view are inconsistent with the user name and password provided by the carrier.

Troubleshooting Procedure

Check the preceding causes one by one. If the fault occurs due to cause 1, use the following solution:

  • Confirm the network authentication mode with the carrier, and run the user command in the APN profile view to check the authentication mode. If the authentication mode is inconsistent with that provided by the carrier, configure the authentication mode to be consistent with that provided by the carrier.
  • Run the user command in the APN profile view to configure auto mode so that the authentication mode can match with that provided by the carrier.

If the fault occurs due to cause 2, obtain the correct user name and password from the carrier and ensure the user name and password are consistent with those configured by running the user command in the APN profile view.
