Applying a Service Service Configuration
31.2.4 Burst-Safe Rate Limiting Service
This command creates a burst-safe type rate limiting. Burst-safe allows an administrator to configure committed access
rates (CAR) and burst-safe rates for any aggregate of flows. The CAR rate is the rate that is always guaranteed. The
burst-safe rate is the best effort rate. This is the rate where some traffic may not get through. It is added bandwidth in
part for bursty periods. See the note in
31.1 "Service Facility Rate Limiting Types" for line card support for burst-safe.
To create a burst-safe rate limiting service, use the following command:
Here is an example:

31.3.1 Applying Services With ACLs
The
service apply rate-limit acl
command is used to apply services using ACLs to interfaces or ports. This
command is for administrators who prefer to use ACLs rather than MF Classifiers. See 31.3.2 "Applying Services
Using the MF-Classifier Command" for more information about MF Classifiers.
To apply services using ACLs, use the following commands:
