Note: ICMP rate-limiting is not supported on meshed ports. (Rate-limiting can reduce the efficiency of paths
through a mesh domain).
Example:
Either of the following commands configures an inbound rate limit of 1% on ports A3 to A5, which are used as
network edge ports:
switch(config) # int a3-a5 rate-limit icmp 1
switch(eth-A3-A5) # rate-limit icmp 1
NOTE: When using kbps-mode ICMP rate-limiting, the rate-limiting only operates on the IP payload
part of the ICMP packet (as required by metering RFC 2698). This means that effective metering is
at a rate greater than the configured rate, with the disparity increasing as the packet size decreases
(the packet to payload ratio is higher).
Also, in kbps mode, metering accuracy is limited at low values, For example, less than 45 Kbps. This
is to allow metering to function well at higher media speeds such as 10 Gbps.
For information on using ICMP rate-limiting and all-traffic rate-limiting on the same interface, seeUsing both
ICMP rate-limiting and all-traffic rate-limiting on the same interface on page 159.
Using both ICMP rate-limiting and all-traffic rate-limiting on the same
interface
ICMP and all-traffic rate-limiting can be configured on the same interface. All-traffic rate-limiting applies to all
inbound or outbound traffic (including ICMP traffic), while ICMP rate-limiting applies only to inbound ICMP traffic.
NOTE: If the all-traffic load on an interface meets or exceeds the currently configured all-traffic
inbound rate-limit while the ICMP traffic rate-limit on the same interface has not been reached, all
excess traffic is dropped, including any inbound ICMP traffic above the all-traffic limit (regardless of
whether the ICMP rate-limit has been reached).
Example:
Suppose:
• The all-traffic inbound rate-limit on port "X" is configured at 55% of the port's bandwidth.
• The ICMP traffic rate-limit on port "X" is configured at 2% of the port's bandwidth.
If at a given moment:
Chapter 6 Port Traffic Controls
Values in this range allow ICMP traffic as a percentage of the bandwidth available
on the interface.
Specifies the rate at which to forward traffic in kilobits per second.
Causes an interface to drop all incoming ICMP traffic and is not recommended.
See the caution.
Clears existing ICMP rate limiting trap condition.
