Policy-Based Routing or PBR with Cisco IOS.

Enabling PBR on 3560 Switch platform

On the 3560 Switch platform you get the message %PLATFORM_PBR-4-SDM_MISMATCH: PBR requires sdm template routing when you apply a route-map to a Interface.

This is because the SDM (Switch Database Management) template. The SDM manages the layer 2 and layer 3 switching information that is maintained in the Ternary Content Addressable Memory (TCAM). The TCAM is used for forwarding lookups. See [1]

Looking at the default configuration the switch had the following SDM configuration. 

Core2#<input>sh sdm prefer</input>
 The current template is "desktop default" template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 8 routed interfaces and 1024 VLANs.

  number of unicast mac addresses:                  6K
  number of IPv4 IGMP groups + multicast routes:    1K
  number of IPv4 unicast routes:                    8K
    number of directly-connected IPv4 hosts:        6K
    number of indirect IPv4 routes:                 2K
  number of IPv4 policy based routing aces:         <notice>0</notice>
  number of IPv4/MAC qos aces:                      512
  number of IPv4/MAC security aces:                 1K

Changing SDM Bias

Core2(config)#<input>sdm prefer routing</input>
Changes to the running SDM preferences have been stored, but cannot take effect
until the next reload.
Use 'show sdm prefer' to see what SDM preference is currently active.
Core2(config)#<input>^Z</input>
Core2#
1d00h: %SYS-5-CONFIG_I: Configured from console by vty0 (10.0.0.30)
Core2#<input>reload</input>

After reboot

Core2#<input>sh sdm prefer</input>
 The current template is "desktop routing" template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 8 routed interfaces and 1024 VLANs.

  number of unicast mac addresses:                  3K
  number of IPv4 IGMP groups + multicast routes:    1K
  number of IPv4 unicast routes:                    11K
    number of directly-connected IPv4 hosts:        3K
    number of indirect IPv4 routes:                 8K
  number of IPv4 policy based routing aces:         <notice>512</notice>
  number of IPv4/MAC qos aces:                      512
  number of IPv4/MAC security aces:                 1K
