This command effectively enables DiffServ on an interface (in a particular direction). The re is
no separate interface administrative 'mode' co mmand for DiffServ.
This command shall fail if any attributes within the policy definition exceed the capabilities of
the interface. Once a policy is successfully attached to an interface, any attempt to change the
policy definition such that it would result in a violation of said interface capabilities shall cause
the policy change attempt to fail.
