Configuring Cs_Ctl Qos On The Switch - Qlogic QLE2740L-DEL User Manual

3–Fibre Channel Configuration
Configuring End-to-End CS_CTL QoS
Therefore, when all three entities support QoS (and it is enabled on the switch and
the target), a default priority value is populated in all FCP_CMND, FCP_DATA,
FCP_XFER_RDY, FCP_RSP, and FCP_CONFIRM frames.
NOTE
i
QoS must be supported by both the switch and target devices.
At the time of publication, CS_CTL QoS has been tested only on the
Brocade SW6510 switch with Fabric OS (FOS) version 7.3.0a.
The following sections describe how to configure end-to-end CS_CTL QoS and
change the default priority levels:


Configuring CS_CTL QoS on the Switch

 Configuring CS_CTL QoS on the Storage Device
 Changing the QoS Priority Levels
Configuring CS_CTL QoS on the Switch
To enable CS_STL QoS on the Brocade SW6510 switch:
1. From the switch, issue the following command:
root> configurechassis
Configure...
2. A list of attributes appear one at a time. After either accepting the default or
entering a different value, the next attribute appears.

For example:
cfgload attributes (yes, y, no, n): [no]
Custom attributes (yes, y, no, n): [no]
system attributes (yes, y, no, n): [no]
fos attributes (yes, y, no, n): [no] y
CSCTL QoS Mode (0 = default; 1 = auto mode): (0..1) [0] 1
3. Reboot the switch.
4. To verify that CS_CTL QoS is enabled, issue the following command:
root> configshow -all | grep fos.csctlMode
Press ENTER to accept the default for cfgload attributes,
Custom attributes, and system attributes.
Type y for fos attributes.
Type 1 for CSCTL QoS Mode.
