Setting QoS zone-based traffic prioritization

1. Connect to the switch and log in using an account with admin permissions.
2. Enter the zoneCreate command to create zones for high and low priority traffic.
3. Enter the cfgAdd command to add the QoS zone to the zone configuration, using the following
4. Enter the cfgSave command to save the change to the defined configuration.
5. Enter the cfgEnable command for the appropriate zone configuration to make the change
6. Enter the portCfgQos command to enable QoS on the E_Ports, using the following syntax:

Traffic prioritization is not supported in McDATA Fabric Mode (interopmode 2) or Open Fabric
Mode (interopmode 3).
You must be running Fabric OS v6.3.0 or later to create QoS zones using D,I notation.
QoS zones using D,I notation are not supported for QoS over FCR.
QoS zones using D,I notation should not be used for loop or NPIV ports.
If QoS is enabled, an additional 16 buffer credits are allocated per port for 8-Gbps ports in LE
mode. See
Chapter 23, "Managing Long Distance Fabrics,"
allocation in extended fabrics.
Trunking considerations: If some ports in a trunk group have QoS enabled and some ports
have QoS disabled, then two different trunks are formed, one with QoS enabled and one with
QoS disabled.
For high priority traffic, use the following syntax:
zonecreate "QOSHid_zonename", "member[; member...]"
For low priority traffic, use the following syntax:
zonecreate "QOSLid_zonename", "member[; member...]"
The id is from 1–5 for high priority traffic, which corresponds to VCs 10–14. For low priority
traffic, the id is from 1–2, which corresponds to VCs 8 and 9. The id is optional; if it is not
specified, the virtual channels are allocated using a round-robin scheme.
syntax:
cfgadd "cfgname", "QOSzonename"
effective.
cfgenable "cfgname"
portcfgqos --enable [slot/]port
The portCfgQos command does not affect QoS prioritization. It only enables or disables the link
to pass QoS priority traffic.
