ip icmp rate-limiting

Limits the rate at which IPv4 Internet Control Message Protocol (ICMP) messages are sent on a network.

Syntax

ip icmp rate-limiting milliseconds

no ip icmp rate-limiting

By default, rate limiting is enabled on the management port, but is disabled on the other ports.

milliseconds: Time interval per ICMP packet in milliseconds. The range is from 0-4294967295. The default is 1000.

Interface configuration mode

Port-channel configuration mode

This is an interface-specific configuration.

The no form of the command will revert to the default setting. Set the interval to 0 to disable IPv4 ICMP rate-limiting.

The following example enables IPv4 ICMP rate-limiting on an Ethernet interface.

device(config)# interface ethernet 3/5
device(conf-int-eth-3/5)# ip icmp rate-limiting 10000
