Rate Limit (pps)
The rate limit value for DHCP packets received on the interface. To
prevent DHCP packets from being used as a DoS attack when DHCP
snooping is enabled, the snooping application enforces a rate limit for
DHCP packets received on untrusted interfaces. If the incoming rate
of DHCP packets exceeds the value of this object during the amount
of time specified for the burst interval, the port will be shutdown. You
must administratively enable the port to allow it to resume traffic for-
warding.
Burst Interval (Sec-
The burst interval value for rate limiting on this interface. If the rate
onds)
limit is unspecified, then burst interval has no meaning.
