QoS

Quality of Service (QoS) works in conjunction with the QoS feature on Brocade switch F_Ports. The

Fabric operating system (FOS) provides a mechanism to assign traffic priority (high, medium, or

low) for a given source and destination traffic flow. By default, all flows are marked as medium.

This feature is supported only on 8 Gbps HBA ports installed on specific switch models that use

Fabric OS 6.2 and later. The following licenses need to be installed on the switch connected to each

HBA port (edge switch):

•Adaptive Networking (AN) license

•Server Application Optimization (SAO) license

To determine if these licenses are installed on the connected switch, execute the Fabric OS

licenseshow command. Refer to the Fabric OS Administrator’s Guide for detailed information about

QoS.

Configuring QoS on the switch side using the BCU

On the switch side, you can create QoS zones using the PWWNs that correspond to devices in a

source/destination traffic flow. You need a Server Application Optimization (SAO) license installed

on the switch to enable QoS. In addition, an Adaptive Networking (AN) license is required on the

switch to enable QoS on the switch ports.

You enable or disable QoS settings on ports with the portCfgQos command. Refer to the Fabric OS

Administrator’s Guide for details about this command on the switch side.

Configuring QoS on the HBA side using the BCU

There are three possible QoS states:

•Enabled, online - QoS is established with the switch.

•Enabled, offline - QoS negotiation failed and QoS was not established with the switch. Possible

reasons for failure could be the license is not installed on the switch or QoS is not enabled on

the port.

•Disabled.

NOTE

You must first enter the bcu port --disable <port_id> command, followed by the

bcu port --enable <port_id> command, before the bcu qos --enable or

bcu qos --disable commands take effect.
