Example: Configuring Rate Limits on SONET/SDH OC48/STM16 IQE PICs
This example limits the transmit rate of a strict-high expedited forwarding queue to 1 megabit per second (Mbps). The scheduler and scheduler map are defined and then applied to the traffic at the [edit interfaces] and [edit class-of-service] hierarchy levels:
[edit class-of-service]
schedulers {scheduler-1 {transmit-rate 1m rate-limit; # This establishes the limitpriority strict-high;}}
scheduler-maps {scheduler-map-1 {forwarding-class expedited-forwarding scheduler scheduler-1;}}
[edit interfaces]s0-2/1/0 {per-unit-scheduler;encapsulation frame-relay;unit 0 {dlci 1;}}
[edit class-of-service]interfaces {so-2/1/0 {unit 0 {scheduler-map scheduler-map-1;shaping-rate 2m;}}}
You can issue the following operational mode commands to verify your configuration (the first shows the rate limit in effect):
- show class-of-service scheduler-map scheduler-map-name
- show class-of-service interface interface-name
