Creating a QoS Fabric Profile

Creating a QoS fabric profile other than the default policy (‟default”) is optional. To create a QoS fabric profile, perform the following:

• assign a policy ID (policy number) — the system does not dynamically assign an ID

• include an optional description of the policy

• assign the mode, either aggregate or per-destination. If no mode is assigned, the default aggregate mode is used.

• configure the to-fabric shaper rate

• (optional) for hierarchical QoS (H-QoS), configure the unshaped SAP CIR rate (see Configuring per-SAP Aggregate Shapers and an Unshaped SAP Aggregate Shaper (H-QoS))

Use the following CLI syntax to configure a QoS fabric profile:

CLI Syntax:

config>qos#
    fabric-profile policy-id aggregate-mode create
        aggregate-rate aggregate-rate [unshaped-sap-cir cir-rate]
        description description-string
    fabric-profile policy-id destination-mode create
        description description-string
        dest-mda <slot/mda | multipoint>
            rate mda-rate

The following example shows the command syntax for creating and configuring a destination-mode QoS fabric profile with an mda-rate of 400 Mb/s for destination adapter cards 1/1 through 1/6.

Example:

*A:7705:Dut-C# configure qos 
fabric-profile 4 destination-mode create
config>qos>fabric-profile$ description "Fabric profile QoS policy 4"
config>qos>fabric-profile$ dest-mda 1/1
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda 1/2
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda 1/3
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda 1/4
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda 1/5
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda 1/6
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ dest-mda multipoint
config>qos>fabric-profile>dest-mda$ rate 400000
config>qos>fabric-profile>dest-mda$ exit
config>qos>fabric-profile$ exit
*A:7705:Dut-C#
