priority (ATM2 IQ Schedulers)

Hierarchy Level

Release Information

Description

For ATM2 IQ interfaces only, assign queuing priority to a forwarding class.

Options

low—Forwarding class has low priority.

high—Forwarding class has high priority.

Usage Guidelines

See Configuring an ATM Scheduler Map.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

priority (Fabric Queues, Schedulers)

Hierarchy Level

Release Information

Description

For T-series and M320 platforms only, specify the fabric priority with which a scheduler is associated.

For a scheduler that you associate with a fabric priority, you cannot include the buffer-size, transmit-rate, or priority statements at the [edit class-of-service schedulers scheduler-name] hierarchy level.

Options

low—Scheduler has low priority.

high—Scheduler has high priority.

The remaining statements are explained separately.

Usage Guidelines

See Associating a Scheduler with a Fabric Priority.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

priority (Fabric Priority)

Hierarchy Level

Release Information

Description

For T-series and M320 platforms only, specify a fabric priority value.

The two hierarchy levels are mutually exclusive. To configure up to eight forwarding classes with one-to-one mapping between forwarding classes and output queues, include this statement at the [edit class-of-service forwarding-classes queue queue-numberclass-name] hierarchy level. To configure up to 16 forwarding classes with multiple forwarding classes mapped to single queues, include this statement at the [edit class-of-service forwarding-classes class class-name queue-num queue-number] hierarchy level.

Options

low—Forwarding class’s fabric queuing has low priority.

high—Forwarding class’s fabric queuing has high priority.

Usage Guidelines

See Overriding Fabric Priority Queuing and Configuring Up to 16 Forwarding Classes.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

priority (Schedulers)

Hierarchy Level

Release Information

Description

Specify packet-scheduling priority value.

Options

priority-level can be one of the following:

• low—Scheduler has low priority.
• medium-low—Scheduler has medium-low priority.
• medium-high—Scheduler has medium-high priority.
• high—Scheduler has high priority. Assigning high priority to a queue prevents the queue from being underserved.
• strict-high—Scheduler has strictly high priority. Configure a high priority queue with unlimited transmission bandwidth available to it. As long as it has traffic to send, the strict-high priority queue receives precedence over low, medium-low, and medium-high priority queues, but not high priority queues. You can configure strict-high priority on only one queue per interface.

Usage Guidelines

See Configuring Priority Scheduling.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
