We have dual Catalyst 4506E switches (IOS 12.2(54)SG1) that work as the core of my company's infrastructure. We recently obtained a new DSL circuit for redundancy, and to reduce the load on our main dedicated Internet connection.
We want to use the DSL for browsing, and only certain people (and servers) are routed through the dedicated old link. Ofcourse, the first thing that comes to mind is "policy based routing". But unfortunately some obstacles showed in my way, first, it came to my knowledge that PBR cannot be done on ASA firewalls, we have two in active/passive fashion that work as gateways and do natting.
So I decided to implement PBR on the core switches, I did the access-list to capture traffic and the route-map to set the next-hop for that traffic, but the problem is when i try to apply policy routing on a vlan interface, or the access switch inbound trunk, the command is not recognized by the switch, there is no "policy route-map" entry after the "ip" command in interface configuration mode.
some cisco documents suggested that I need to enable extended routing on the switch first with the command "sdm prefer routing extended-match", but that too doesn't exist on the configuration mode!! so I'm clueless now on how to enable policy based routing on our core switches.
Your kind help & segestions are highly appreciated.

Hi,
this feature is not supported by IP Base image. You need Enterprise services image to do this.

Hi majdi,
You cannot do policy based routing on the ASA even with the highest available license, because policy based routing is not supported on the ASA or PIX.
It's supported only in IOS and if you want to which model/IOS has the command you need you can always use the
cisco feature navigator.

Hi,
Can you post sh version output.
It won't work on a switchport interface like the trunk but only on a L3 interface like a SVI or routed port.

Hey Kishore,
I see. Thank you very much.
What I could do now is connect the DSL modem to core switches (new vlan) directly and added selected users' ports to the new vlan. So now I'm actually partially relying on the modem's firewall! (ugggglyyy). I'm under the assumption that the dynamic WAN IP of the modem being changed frequently plus its natting can actually protect me to some level. utleast till I get my IOS upgraded.
Thanks again for the valueble replies gents.
