The following guidelines pertain to applying a bandwidth policer to traffic:
You can use a bandwidth policer to rate-limit protocol-specific traffic (not
at the input or output of a logical interface.
You can apply a bandwidth policer directly to protocol-specific input or output traffic

You cannot use a bandwidth policer for forwarding-table filters.
You cannot apply a bandwidth policer to an aggregate interface, a tunnel interface, or
