Network Queue QoS Policies
In This Section
This section provides information to configure network queue QoS policies using the command line interface.
Topics in this section include:
•
Overview
•
Basic Configurations
•
Default Network Queue Policy Values
•
Service Management Tasks
Overview
Network queue policies define the ingress network queuing at the MDA network node level. Network queue policies are also used at the Ethernet port and SONET/SDH path level to define network egress queuing.
There is one default network queue policy. Each policy can have up to 16 queues (unicast and multicast). The default policies can be copied but they cannot be deleted or modified. The default policy is identified as network-queue default. Default network queue policies are applied to MDA network ingress ports. You must explicitly create and then associate other network queue QoS policies.
For information about the tasks and commands necessary to access the command line interface and to configure and maintain your devices, refer to CLI Usage chapter in the Basic System Configuration Guide.
 
Network Queue Parent Scheduler
Network queues support port scheduler parent priority-level associations. Using a port scheduler policy definition and mapping network queues to a port parent priority level, HQoS functionality is supported providing eight levels of strict priority and weights within the same priority. A network queue’s bandwidth is allocated using the “within-cir” and “above-cir” scheme normal for port schedulers.
Queue CIR and PIR percentages when port-based schedulers are in effect will be based on frame-offered-load calculations.
A network queue with a port parent association exists on a port without a scheduler policy defined will be considered to be orphaned.
Refer to QoS Scheduler Policies for more information about queue parental association scope.
Basic Configurations
A basic network queue QoS policy must conform to the following:
•
Each network queue QoS policy must have a unique policy name.
•
Queue parameters can be modified, but cannot be deleted.
 
Create a Network Queue QoS Policy
Configuring and applying QoS policies other than the default policy is optional. A default network queue policy is applied to MDA network ingress ports.
To create an network queue policy, define the following:
•
Enter a network queue policy name. The system will not dynamically assign a name.
•
Include a description. The description provides a brief overview of policy features.
•
Forwarding class — You can assign a forwarding class to a specific queue.
Use the following CLI syntax to create a network queue QoS policy:
Network Queue FC
Network Queue Que
CLI Syntax: config>qos
network-queue policy-name
description description-string
fc fc-name
multicast-queue queue-id
queue queue-id
queue queue-id [multipoint] [queue-type]
cbs percent
high-prio-only percent
mbs percent
port-parent [weight weight] [level level] [cir-weight cir-weight] [cir-level cir-level]
rate percent [cir percent]

Applying Network Queue Policies
Apply network queue policies to the following entities:
•
MDAs
•
Ethernet Ports
•
SONET/SDH Ports
 
MDAs
Use the following CLI syntax to apply a network queue policy to an MDA network ingress port:
CLI Syntax: config>card
mda mda-slot
network
ingress
queue-policy name
 
The following output displays MDA network ingress queue policy reverted to the default policy.

Editing QoS Policies
 
Deleting QoS Policies
A network queue policy is associated by default with MDA network ingress ports. You can replace the default policy with a customer-configured policy, but you cannot entirely remove a QoS policy. When you remove a QoS policy, the policy association reverts to the default network-queue policy default.
To delete a user-created network queue policy, enter the following commands:
CLI Syntax: config>qos# no network-queue policy-name
Example: config>qos# no network-queue nq1
 
Remove a Policy from the QoS Configuration
To delete a network policy, enter the following commands:
CLI Syntax: config>qos# no network-queue policy-name
 
Example: config>qos# no network-queue test
 
Copying and Overwriting QoS Policies
You can copy an existing network queue policy, rename it with a new policy ID name, or overwrite an existing network queue policy. The overwrite option must be specified or an error occurs if the destination policy ID exists.
CLI Syntax: config>qos# copy network-queue source-policy-id dest-policy-id [overwrite]
 
Example:	config>qos# copy network-queue nq1 nq2
The following output displays the copied policies:

Editing QoS Policies
You can change existing policies, except the default policies, and entries in the CLI. The changes are applied immediately to all interfaces where the policy is applied. To prevent configuration errors use the copy command to make a duplicate of the original policy to a work area, make the edits, and then overwrite the original policy.
