RE: 802.1Q - MAC Spoofing

Hi Ben,

I am attaching a small write up on what I am trying to do and what is the test bed.  

Kindly let me know if there is any issues in the configuration or understading. Also, if you need more information or explantion kindly let me know. 

Basically the whole stuff is not working.. 

I tried both the option suggested by you for vconfig :

1. arp-filter technique - didn't work.

2. vconfig interface being on a different subnet and configuring the corresponding port at the switch on the same subnet and vlan id. This also didn't work. I was unable to ping the host from the switch itself. (both host and the switch were configured with an IP address on the same subnet. This IP address was on a different subnet than the primary etho interface at the linux host.)

The gist of the problem is Vlan tagged frames. 

                            VLAN Tagging at trunk interface : 

                            When the port was configured in the trunk mode at L2 switch and linux host configured for vlan interface, we expected the frames on the trunked interface

                            to be in 802.1Q format. But this was never the case.

                              We have posted the question to linux org on the same.

Thanks a lot for your time and help.

Regards,

Chaitra
