Routing policy commands are supported on M6100 series switches 
only.

Use this command to identify a route map to use for policy-based routing on an interface 
specified by route-map-name. Policy-based routing is configured on the interface that 
receives the packets, not on the interface from which the packets are sent. 

When a route-map applied on the interface is changed, that is, if new statements are added 
to route-map or match/set terms are added/removed from route-map statement, and also if 
route-map that is applied on an interface is removed, route-map needs to be removed from 
interface and added back again in order to have changed route-map configuration to be 
effective.

Route-map and Diffserv cannot work on the same interface.

Heap Size

in Heap
