Network Queue QoS Policies

Quality of Service Guide

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
auto-expedite — the system auto-defines the way the queue is serviced by the
hardware. When auto-expedite is defined on the queue, the queue is treated in an
expedited manner when all forwarding classes mapped to the queue are configured
as expedited types nc, ef, h1, or h2. When a single non-expedited forwarding class
is mapped to the queue (be, af, l1, or l2), the queue automatically falls back to non-
expedited status.
Values expedite, best-effort, auto-expedite
Default auto-expedite
create — keyword used to create a network QoS policy
avg-frame-overhead
Syntax avg-frame-overhead percent
no avg-frame-overhead
Context config>qos>network-queue>queue
Description The 7705 SAR does not support the avg-frame-overhead command. It is always set to 0 and
cannot be modified.
adaptation-rule
Syntax adaptation-rule [pir adaptation-rule] [cir adaptation-rule]
no adaptation-rule
Context config>qos>network-queue>queue
Description This command defines the method used by the system to derive the operational CIR and PIR
settings when the queue is provisioned in hardware. For the CIR and PIR parameters
individually, the system attempts to find the best operational rate depending on the defined
constraint.
The no form of the command removes any explicitly defined constraints used to derive the
operational CIR and PIR created by the application of the policy. When a specific adaptation-
rule is removed, the default constraints for rate and cir apply.
