Maintaining IPoE Access

Maintaining IPoE Access

Maintaining BRAS access includes monitoring the operating status of the BRAS, clearing the statistics about login and logout users, and debugging in the case of failures.

Displaying BRAS Access Information

You can view BRAS access information, including user login and logout records.

Context

After the preceding configurations, run the following display commands in any view to check the BRAS configurations.

Procedure

  1. Run the display web-auth-server configuration command to check the configuration of the Web authentication server.
  2. Run the display bas-interface command to check the configuration of the BAS interface.
  3. Run the display aaa online-fail-record command to check the login failure records.
  4. Run the display aaa offline-record command to check the logout records.
  5. Run the display aaa abnormal-offline-record command to check the abnormal logout records.
  6. Run the display call rate command to check the total call put-through rate for all types of users.
  7. Run the display access-user command in any view to check information about online users.

    The protocol-statistics enable command run in the AAA view enables statistics about protocol packets, including ND, PPPoE, PPP, DHCPv4, and DHCPv6 packets.

  8. Run the display user-flow-statistics [ domain domain-name ]command in any view to check users' uplink and downlink traffic statistics.
  9. Run the display access trigger user-table command in any view to check information about users whose access packets are limited on a board.

Clearing BRAS Access Information

If there are too many login and logout records, you can delete the BRAS access authentication information.

Context

BRAS access information cannot be restored after it is cleared. Exercise caution when running the commands.

To clear BRAS access information, run the following reset commands.

Procedure

  1. Run the reset aaa online-fail-record command in the user view to clear the login failure records.
  2. Run the reset aaa offline-record command in the user view to clear the logout records.
  3. Run the reset aaa abnormal offline-record command in the user view to clear the abnormal logout records.
  4. Run the reset access trigger user-table command in any view to clear information about users whose access packets are limited on a board.
  5. Run the reset call rate command in the user view to clear the call rate statistics of users.
  6. Run commit

    The configuration is committed.

Displaying BRAS Access Statistics

Displaying BRAS access statistics helps fault locating and traffic tracing.

Procedure

  • Run the display access statistics packet discard mac-spoofing [ ipoe | pppoe ] [ ipv4 | ipv6 ] { interface { interface-name | interface-type interface-number } | slot slot-id } command in any view to display statistics about MAC-spoofing-dropped packets of access users.
  • Run the display access statistics trigger slot slot-id command in any view to display user packet statistics by the board.
  • Run the display layer3-subscriber statistics port-mismatch command in any view to display statistics on Layer 3 users' packets that are discarded due to an interface mismatch.

Example

Run the display access statistics packet discard mac-spoofing slot slot-id command, you can view statistics about MAC-spoofing-dropped packets on the board in slot 1.

<HUAWEI> display access statistics packet discard mac-spoofing slot 1
 Slot 1 discard statistics:
--------------------------------------------------------------------------
             IPv4 packets(high, low)    IPv6 packets(high, low)
--------------------------------------------------------------------------
 pppoe       (4294967295, 4294967295)    (4294967295, 4294967295)
 ipoe        (4294967295, 4294967295)    (4294967295, 4294967295)
--------------------------------------------------------------------------
Run the display access statistics trigger slot slot-id command, you can view statistics about user packets on the board in slot 2.
<HUAWEI> display access-statistics trigger slot 2
IPv4 Packet information:
Passed packet(s)   : 0
Dropped packet(s)  : 0    
IPv6 Packet information:
Passed packet(s)    : 0
Dropped packet(s)  : 0
Run the display layer3-subscriber statistics port-mismatch command, you can view statistics on Layer 3 users' packets that are discarded due to an interface mismatch.
<HUAWEI> display layer3-subscriber statistics port-mismatch
  ---------------------------------------------------------------------------   
   Interface                       Statistics

Clearing BRAS Access Statistics

Before you collect statistics on an interface within a certain period, clear the existing statistics on this interface.

Context

Broadband remote access server (BRAS) access statistics cannot be restored after being cleared. Therefore, exercise caution when performing the following operations.

Procedure

  • Run the reset vlan-statistics interface interface-type interface-number.subinterface-number pevlan pe-vlan-id [ cevlan ce-vlan-id ] command to clear statistics about traffic and Point-to-Point Protocol (PPP) packets on a specified sub-interface bound to a specified virtual local area network (VLAN).

    NOTE:

    The reset vlan-statistics interface interface-type interface-number.subinterface-number pevlan pe-vlan-id [ cevlan ce-vlan-id ] command can be configured only through a PAF file.

  • Run the reset access statistics packet discard mac-spoofing [ ipoe | pppoe ] [ ipv4 | ipv6 ] { interface { interface-name | interface-type interface-number } | slot slot-id } command to clear statistics about MAC-spoofing-dropped packets of access users.
  • Run the reset access statistics trigger slot slot-id command to clear access packet statistics on a board.
  • Run the reset layer3-subscriber statistics port-mismatch [ interface { interface-name | interface-type interface-num } ] command to clear statistics on Layer 3 users' packets that are discarded due to an interface mismatch.

Configuring Automatic Blocking of User Access Domains and Boards of a BRAS

After automatic blocking of user access domains and boards is configured on a BRAS, the BRAS automatically blocks the user access domains and boards and logs out online users.

Context

Before a device upgrade, you must manually block the user access domains and boards of the device and log out online users, then run the reboot command to restart the device after users go offline. Instead, you can run the bras auto-upgrade enable command to automatically block the user access domains and boards of the device and log out online users, then run the reboot command to restart the device.

The reboot command must be run.

Procedure

  1. In the user view, run:

    bras auto-upgrade enable

    Automatic blocking of user access domains and boards is configured on a BRAS.

  2. Run reboot

    The system is restarted.

    The bras auto-upgrade enable command is not stored in the configuration file of the system, and therefore must be run each time you need this function.

  3. Run commit

    The configuration is committed.
