Configuring Up to Eight Forwarding Classes

For J-series, M320, and T-series platforms, you can configure more than four forwarding classes and queues.

On J-series Services Routers, you can configure up to eight forwarding classes and eight queues. On the M120, M320, MX-series, and T-series platforms, you can configure up to 16 forwarding classes and eight queues, with multiple forwarding classes assigned to single queues. This section discusses the J-series platform configuration of eight forwarding classes and queues with a one-to-one mapping. For information about the M320 and T-series platform configuration, see Configuring Up to 16 Forwarding Classes.

To configure up to eight forwarding classes, include the queue statement at the [edit class-of-service forwarding-classes] hierarchy level:



[edit class-of-service forwarding-classes]

queue queue-number class-name;

The output queue number can be from 0 through 7, and you must map the forwarding classes one-to-one with the output queues. The default scheduler transmission rate and buffer size percentages for queues 0 through 7 are 95, 0, 0, 5, 0, 0, 0, and 0 percent.
