The administrator can configure the rate and burst interval. Rate limiting is
configured independently on each physical interface and may be enabled on
both trusted and untrusted interfaces. The rate limit is configurable in the
range of 0-300 packets per second and the burst interval in the range of 1-15
seconds. In general, a rate limit of under 100 pps is valid for untrusted
interfaces.
