ACL-based rate limiting using traffic policies
The software allows you to add a reference to a non-existent TPD in an ACL statement and to bind
that ACL to an interface. The software does not issue a warning or error message for non-existent
TPDs.
Use the no form of the command to delete a traffic policy definition. Note that you cannot delete a
traffic policy definition if it is currently in use on a port. To delete a traffic policy, first unbind the
associated ACL.
The traffic-policy <TPD name> parameter is the name of the traffic policy definition. This value can
be eight or fewer alphanumeric characters.
The rate-limit adaptive cir <cir value> specifies that the policy will enforce a flexible bandwidth limit
that allows for bursts above the limit.The <cir value> variable is the committed information rate in
kbps. Refer to Table 290.
The cbs <cbs value> parameter is the committed burst size in bytes. Refer to Table 290.
The pir <pir value> parameter is the peak information rate in kbps. Refer to Table 290.
The pbs <pbs value> parameter is the peak burst size in bytes. Refer to Table 290.
The exceed-action <action> parameter specifies the action to be taken when packets exceed the
configured values. Refer to “Specifying the action to be taken for packets that are over the limit” on
page 1781.
The count parameter is optional and enables ACL counting. Refer to “ACL statistics and rate limit
counting” on page 1782.
