QoS on Pix running version prior to 7

[kalvarez74]

I would like to know how the Pix running version prior to 7.x process a packet with qos marking. I am pretty sure the pix will not honor the qos, but what it does to the packet, strip off the qos?, or ignore it?. The same with version 7.0 and how about the ASA?.

I tested this recently on a 501 running 6.3(5) and it just passes the ToS byte without any changes.
