ACL-based rate limiting policies consume entries based on the number of statements in an
ACL.

See the limits in

Configuring rate limiting policies
Configuring rate-limiting policies involves using the rate-limit command and specifying the
requested rate and maximum burst at the interface level of the CLI.
Software release 02.4.00 adds rate limiting to outbound ports.
Configuring a port-based rate limiting policy
Only one port-based rate limiting policy can be applied to an inbound port.
To configure a port-based rate limiting policy, enter commands such as the following.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# rate-limit out 500000000 750000000
Average rate is adjusted to 499639656 bits per second
The commands configure a rate limiting policy for outbound traffic on port 1/1. The policy requests
to limit the rate on all inbound traffic to 500 Mbps with a maximum burst size of 750 Mbps. The
device adjusts the requested rate to 499639656 bits per second.
Syntax: [no] rate-limit input | output <requested-rate> <maximum-burst>
input applies rate limiting to inbound traffic on the port. Input can be abbreviated as in.
Output applies rate limiting to outbound traffic on the port. Output can be abbreviated as out.
The <requested-rate> parameter specifies the maximum rate allowed on a port during a
one-second interval. The minimum configurable requested rate is 20,345 bps. The maximum
configurable rate limiting rate is near line-rate.
Refer to
“Requested rate”
on page 496 for more details.
The <maximum-burst> parameter specifies the extra bits above the requested rate that traffic can
have. Refer to
“Maximum burst”
on page 496 for more details.
