device(config-if-range)#service-policy input qos-classify-lan
The policy qos-classify-lan cannot be attached to the interface Gi1/25 since it has 'set' actions. IP Routing and CEF Switching are required for 'set' actions to be effective.Please enable IP routing and CEF switching.
% Range command terminated because it failed on GigabitEthernet1/25

do i really need to enable IP CEF and IP routing? (even though i used my device in Access layer)

Re: unable to apply classification policy-map on Cisco 4900

Hi Mc,

Yes, you need to enable CEF on the switch or the policy will not take effect:

From the config guide:

You cannot enable marking commands on an interface until IP routing is enabled globally. If IP routing is disabled globally and you try to configure the service policy on an interface, the configuration is accepted but it does not take effect. You are prompted with the message: "Set command will not take effect since CEF is disabled. Please enable IP routing and CEF globally.. " To enable IP routing globally, issue the ip routing and ip cef global configuration commands. After you do this, the marking commands take effect.

Here is the config guide:
