Is it possible to configure a 3550 switch to make what are essentialy policy routing decisions based upon a port?? I have a 3550 switch in my customers DMZ which is the egress point off of the production network to the Internet. I have 2 ISP connected to the switch; both having great bandwidth.
The tranlation that I have for our MX and RDNS records is out of one of the ISP's only.
I would like to be able to configure the switch if at all possible so that when it received any SMTP packet outbound from our Mail Server, that it will make the decision to send it out the correct ISP.
I would like to the switch to load balance between the two gateways for all other traffic.
Please help. I looke at policy routing, but could not see where I would configure port criteria...

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
