Checking BRAS Access Statistics

This section describes how to check BRAS access statistics to facilitate fault diagnosis 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 about a specified board.
Run the display layer3-subscriber statistics port-mismatch command in any view to display statistics about 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 1.

<HUAWEI> display access-statistics trigger slot 1
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 about Layer 3 users' packets that are discarded due to an interface mismatch.
