PBR on 3750

Hello, I just configured PBR on my 3750 but it's not working. Please help

I configure the ACL and the route-map, apply to interface but traffic is not working as it should. Any ideas?

Re: PBR on 3750

Few things to be aware of "the 3550/3750 PBR:

- TCAM based hardware based PBR does not support denys followed by permit clauses as TCAM subtraction is not supported ". If you have ACLs with denys followed by permit, traffic will get software switched and you will see CPU hit.

- sdm prefer routing must be used

use "sh sdm prefer"

- ip services software is required, the ip policy command is not available on

ip base

- you can not use set interface, set default next hop or set default interface within the route-map

- you can use the ip local policy route-map command to enable policy routing

on locally generated packets
