Layer 3 Routing Commands 1532
ip icmp error-interval
Use the ip icmp error-interval command to limit the rate at which IPv4
ICMP error messages are sent. The rate limit is configured as a token bucket
with two configurable parameters: Burst-size and burst-interval.
To disable ICMP rate limiting, set burst-interval to zero. Use the no form of
this command to return burst-interval and burst-size to their default values.
