Creating a Shaper QoS Policy and Shaper Groups

Configuring and applying shaper QoS policies is optional. If no shaper QoS policy is explicitly defined, the default shaper QoS policy (‟default”) is applied.

To create a new shaper policy, define the following:

• a shaper policy name — the system does not dynamically assign a name

• a description (optional) — a brief description of the policy

• a shaper group (optional) and its PIR and CIR values — a shaper group is a dual-rate aggregate shaper that is used mainly as a per-customer (MSS) aggregate shaper

• an unshaped SAP shaper group (optional) — the shaper group used by the group of all unshaped SAPs for the purpose of traffic arbitration with the shaped SAPs on a port

Use the following CLI syntax to configure a shaper policy and shaper groups within the shaper policy:

CLI Syntax:

config>qos#
    shaper-policy policy-name [create] 
        description description-string
        shaper-group shaper-group-name [create] 
            description description-string
            rate pir-rate [cir cir-rate] 
        unshaped-sap-shaper-group shaper-group-name

Example:

config>qos 
config>qos$ shaper-policy "shaper_policy_2" create
config>qos>shaper-policy$ shaper-group ‟sg1” 
config>qos>shaper-policy>shaper-group$ rate 1000 cir 200
config>qos>shaper-policy>shaper-group$ exit
config>qos>shaper-policy$ shaper-group ‟unshaped_sg1” 
config>qos>shaper-policy>shaper-group$ rate 500 cir 100
config>qos>shaper-policy>shaper-group$ exit
config>qos>shaper-policy>unshaped-sap-shaper-group$ ‟unshaped_sg1”
config>qos>shaper-policy$ exit
config>qos$ 

The following output shows the configuration for ‟shaper_policy_2”:
