Configuring Class of Service for Channelized IQ Interfaces

On channelized IQ interfaces, you can apply class of service at the logical interface level for Frame Relay data-link connection identifiers (DLCIs). To configure class-of-service schedulers at the logical interface level, perform the following tasks:

• Configuring a Class-of-Service Scheduler Map
• Associating the Scheduler with a DLCI on a Channelized IQ Interface

As an alternative to applying class of service at the logical interface level, you can apply rate limiting to the physical interface of a channelized IQ interface. To configure, include the shaping-rate statement at the [edit class-of-service interfaces interface-name] hierarchy level.

Note: For logical interfaces in a channelized IQ interface, you can apply both the shaping-rate statement at the [edit class-of-service interfaces interface-name unit logical-unit-number] hierarchy level and the per-unit-scheduler statement at the [edit interfaces interface-name] hierarchy level. For physical interfaces and channels in a channelized IQ interface, you can configure either the shaping-rate statement at the [edit class-of-service interfaces interface-name] hierarchy level or the per-unit-scheduler statement at the [edit interfaces interface-name] hierarchy level, but not both statements at the same time.

For more information on configuring class of service, see the JUNOS Class of Service Configuration Guide.
