QoS Policies
When defining the CIR for a queue, the value specified is the administrative CIR for the queue.
The user has some control over how the administrative CIR is converted to an operational CIR
should the hardware not support the exact CIR and PIR combination specified. The interpretation
of the administrative CIR is discussed below in Adaptation Rule on page 33
Although the 7210 SAS is flexible in how the CIR can be configured, there are conventional
ranges for the CIR based on the forwarding class of a queue. A access egress queue associated
with the high-priority class normally has the CIR threshold equal to the PIR rate although the 7210
SAS allows the CIR to be provisioned to any rate below the PIR should this behavior be required.
The CIR for a queue is provisioned on egress within access egress QOS policy.
The CIR for the access uplink queues are defined within network queue policies based on the
forwarding class. The CIR for the access uplink queues is specified as a percentage of the network
interface bandwidth.
