ICMP echo reply rate limit

[marcusbrutus]

Hi Experts,

Just wish to ask if any of you know of a setting on either an ASA or IOS that would allow it to rate-limit the number of echo replies it sends back to an initiating source?  Couldn't find any docs on this except icmp rate limit on unreachables.

Thanks in advance.

Hello Marcus,

On the ASA as you are already aware we only have the choice of modifying the ICMP unreachable rate,

With the IOS the rate-limit for ICMP unreachable replies  will be rate limited to one every 500ms

use:

show ip icmp rate-limit

Besides that I have not seen any other information that you could customize.

Regards
