The latest version of Wireshark does not exhibit this problem.  I suggest you upgrade from 1.2.9 to 1.4rc1 or wait 
until the official 1.4 release comes out which should be very soon.

Subject: [Wireshark-users] hi，can you give me some help about PPPoE packets?

Hi,dear shark,
  I have a question about ‘PPPoE payload length’.
  As we know In RFC 2516,It defined the ‘Length field’ :

The LENGTH field is sixteen bits. The value, in network byte order,
indicates the length of the PPPoE payload. It does not include the
length of the Ethernet or PPPoE headers.


You can refer to the packet that be captured in SNI(service network interface) in the annex,you can find that
In dscovery stage ,the payload length is right ,however in session stage ,wireshark judge it has some error because it
think the ‘payload length’ should contain the pads and CRC.

incongruous operation mechanism between dscovery stage and session stage in the PPPoE.

Now we use the R1.2.9,when will the issue be delivered?

Best regards
                                    Yours
                                                                               Wei liu
