Behaving like a switch

Behaving like a switch

[Vimal]

Hello,

I am running Mac OS X Leopard. I would like to perform some
experiments by behaving like a switch. This is the current setup:

[My Laptop] <-----> [Switch] <===(part of a vlan)===>

The switch port to which I am connected to is on a particular vlan.
However, if trunking is enabled on my port, I can see all vlan
traffic.

I would like to configure my laptop so that the default ethernet
device (en0) would be connected to a switch via a trunk line, and all
packets that leave my computer via en0 of a specific type (say, only
ipv6 packets) should be tagged with another vlan-id. The setup should
be such that bidirectional communication is possible.

I have seen that one can setup a vlan virtual device using ifconfig.
But I am unable to setup the policy by which packets are appropriately
forwarded.

Thanks,

I don't know if this is possible in OS X or not.  You will have better 
luck asking in an OS X specific venue, not a Linux NetFilter venue.

Alright. I thought of asking it here because it seems like most of the
OS X network tools are BSD-Like. Esp. ifconfig, ipfw and such.
