Ip Dhcp Snooping Log-Invalid - Dell N1100-ON Reference Manual

The administrator can configure the rate and burst interval. Rate limiting is

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.
