3–Fibre Channel ConfigurationConfiguring End-to-End CS_CTL QoS87 CU0354604-00 PSetting the QoS Priority Level for a Virtual Port inQConvergeConsole GUIFigure 3-36 shows how to set the QoS priority level for a virtual port inQConvergeConsole GUI.Figure 3-36. Setting the QoS Priority LevelConfiguring End-to-End CS_CTL QoSQLogic’s class specific control (CS_CTL) QoS implementation is an end-to-endsolution, encompassing the initiator (2600 Series Adapters), the switches, and thetarget (storage). The 2600 Series Adapter stamps the priority value (high,medium, low) in the CS_CTL field of the Fibre Channel frame. All three entities(initiator, switch, and target) honor this priority value at their respective levels.NOTEBy default, the QoS of the physical port is set to High, and the QoS of thevirtual port is set to Low.NOTEFor information about CS_CTL QoS that is not end-to-end, see “ConfiguringCS_CTL QoS” on page 84.
