shows how to set the QoS priority level for a virtual port in
QConvergeConsole GUI.
Figure 3-36. Setting the QoS Priority Level
Configuring End-to-End CS_CTL QoS
QLogic’s class specific control (CS_CTL) QoS implementation is an end-to-end
solution, encompassing the initiator (2700 Series Adapters), the switches, and the
target (storage). The 2700 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.
NOTE
By default, the QoS of the physical port is set to
High
, and the QoS of the
virtual port is set to
Low
.
NOTE
For information about CS_CTL QoS that is not end-to-end, see
