Configure Global iSCSI Settings
To configure the global iSCSI settings on the switch:
1. Launch a web browser
.
2. In the address field of your web browser
, enter the IP address of the switch.
The login window opens.
3. Enter admin as the user name, enter your local device password,
and click the Login
button.
The first time that you log in, no password is required. However, you then must specify a
local device password to use each subsequent time that you log in.
The System Information page displays.
4. Select Switching > iSCSI > Basic > Global Configuration.
5. In the iSCSI Status field, select Enable or Disable.
This globally enables or disables the iSCSI Optimization feature. By default, iSCSI
Optimization is disabled.
6. Select the QoS Profile VLAN Priority T
ag or DSCP radio button.
This specifies the Quality of Service (QoS) profile that is applied to iSCSI flows. By
default, iSCSI flows are assigned to the highest VLAN Priority tag (VPT)/DSCP mapped
to the highest queue not used for switch management or voice VLAN.
Setting the VLAN Priority tag/DSCP sets the QoS profile which determines the egress
queue to which the frame is mapped.
The switch default setting for egress queues
scheduling is Weighted Round Robin (WRR). Complete the QoS setting by configuring
the relevant ports to work in other scheduling and queue management modes through the
Class of Service settings. Depending on the platform, these choices might include strict
priority for the queue used for iSCSI traffic. The downside of strict priority is that, in certain
circumstances (under heavy high priority traffic), other lower priority traffic might get
starved. In WRR, the queue to which the flow is assigned to can be set to get the required
percentage.
7. Configure the global traf
fic class mapping in Class of Service.
