Service Queue QoS Policy Commands
executed, the default PIR of max is assumed.
Fractional values are not allowed and must be given as a positive integer.
The actual PIR rate is dependent on the queue's adaptation-rule parameters and the actual hardware
where the queue is provisioned.
Values
Default
cir-rate — The cir parameter overrides the default administrative CIR used by the queue. When the rate
command is executed, a CIR setting is optional. When the rate command has not been executed or the
cir parameter is not explicitly specified, the default CIR (0) is assumed.
Fractional values are not allowed and must be given as a positive integer.
Values
Default
xp-specific
Syntax
xp-specific
Context
config>qos>sap-egress>queue
Description
This command enables the context to configure IOM3-XP specific information. The xp-specific CLI node
within the SAP egress QoS policy queue context is used to specify queue parameters or behavior specific to
the Q2 traffic management feature set. All IOMs within the XP family utilize the Q2 for traffic management
queuing functions. When the SAP egress QoS policy is applied to a SAP on an IOM3-XP, any commands
and parameters defined within the xp-specific context will either override or augment the generic commands
and parameters defined for the specific queue ID.
In the event that the QoS policy is applied to a SAP on a non-IOM3-XP, the commands and parameters
within the xp-specific node are ignored.
When the QoS policy is applied to a LAG SAP that spans XP and non-XP IOMs, the xp-specific commands
and parameters are applied for the SAP queues created on the IOM3-XP LAG links.
wred-queue
Syntax
wred-queue [policy slope-policy-name]
no wred-queue
Context
config>qos>sap-egress>queue>xp-specific
Description
This command alters the generic buffer pool association of the queue for the purpose of allowing queue-
specific WRED slopes with minimal provisioning. When the wred-queue command is defined and the
queue ID is created on an IOM3-XP, a buffer pool is created specifically for the queue and the queue obtains
all buffers from that pool. The size of the pool is the same as the size of the queue. In this manner, the
WRED slopes that operate based on the pool's buffer utilization are also reacting to the congestion depth of
