How can I set ICMP rate-limiting in a Cisco router? Here on the manual page they only talk about ICMP unreachable messages:

ip icmp rate-limit unreachable [df] [ms] [log [packets] [interval-ms]] 

Is there anything that also includes other ICMP message types? For instance, what if I want to set a limit on the number of time-exceeded messages sent?
