VPRN Service Configuration Commands
Page 786 7210 SAS-X OS Services Guide
In the PIR loop, the priority of the queues cannot be configured. The system assigns the
priority to the queues based on the cir-level associated with the queue. to see the default
assignment of pir-levels to the queue corresponding to the cir-level configured by the user.
Values 1 — 8 (8 is the highest priority)
Default 1
pir-weight pir-weight — Specifies the relative weight of the queue with respect to the other queues.
The weight parameter is used only in the PIR loop. If a queues level parameter is set to ‘8’, the
weight parameter is ignored by the system.
Values 1 — 100
Default 1
queue-mgmt
Syntax queue-mgmt name
Context config>service>epipe>sap>ingress>queue-override>queue
config>service>vpls>sap>ingress>queue-override>queue
config>service>ies>sap>ingress>queue-override>queue
config>service>vprn>sap>ingress>queue-override>queue
Description This command specifies the WRED and buffer parameters associated with the queue.
All the queues in the system allocate buffers from the system pool.
Parameters name —
Specifies the name of the queue-management policy.
rate
Syntax rate pir-rate [cir cir-rate]
no rate
Context config>service>epipe>sap>ingress>queue-override>queue
config>service>vpls>sap>ingress>queue-override>queue
config>service>ies>sap>ingress>queue-override>queue
config>service>vprn>sap>ingress>queue-override>queue
Description This command can be used to override specific attributes of the specified queue’s Peak Information
Rate (PIR) and the Committed Information Rate (CIR) parameters. The PIR defines the maximum
rate that the queue can transmit packets out an egress interface (for SAP egress queues). Defining a
PIR does not necessarily guarantee that the queue can transmit at the intended rate. The actual rate
sustained by the queue can be limited by oversubscription factors or available egress bandwidth.
The CIR defines the rate at which the system prioritizes the queue over other queues competing for
the same bandwidth. In-profile packets are preferentially queued by the system at egress and at
