queue
Syntax queue queue-id [queue-type] [queue-mode] [create]
no queue queue-id
Context config>qos>sap-ingress
Description This command enables the context to configure a service ingress policy queue.
Explicit definition of an ingress queue’s hardware scheduler status is supported. A single
ingress queue allows support for multiple forwarding classes.
The default behavior automatically chooses the expedited or non-expedited nature of the
queue based on the forwarding classes mapped to it. As long as all forwarding classes
mapped to the queue are expedited (nc, ef, h1, or h2), the queue is treated as an expedited
queue by the hardware schedulers. When any non-expedited forwarding classes are mapped
to the queue (be, af, l1, or l2), the queue is treated as best effort (be) by the hardware
schedulers.
The expedited hardware schedulers are used to enforce expedited access to internal switch
fabric destinations. The hardware status of the queue must be defined at the time of queue
creation within the policy.
The no form of this command removes the queue-id from the service ingress policy and from
any existing SAPs using the policy. If any forwarding class forwarding types are mapped to
the queue, they revert to their default queues. When a queue is removed, any pending
accounting information for each service queue created due to the definition of the queue in
the policy is discarded.
Parameters queue-id — the queue identifier for the queue, expressed as an integer. The queue-id
uniquely identifies the queue within the policy. This is a required parameter each time
the queue command is executed.
Values 1 to 8
queue-type — the expedite, best-effort, and auto-expedite queue types are mutually
exclusive. Each defines the method that the system uses to service the queue from
a hardware perspective. A keyword must be specified at the time the queue is
created in the service ingress policy. If an attempt is made to change the keyword
after the queue is initially defined, an error is generated.
expedite — the queue is treated in an expedited manner independent of the forwarding
classes mapped to the queue
best-effort — the queue is treated in a non-expedited manner independent of the
forwarding classes mapped to the queue
