Enabling and disabling QoS priority-based flow control
Priority-based flow control (PFC) can be used to control network congestion. PFC can be used to
selectively pause lower priority traffic classes to ensure that high priority and delay-sensitive traffic
are not affected by network congestion. For example, if a large storage transfer is monopolizing the
network and causing congestion, PFC can be used to pause the storage transfer so other traffic
may use the network.
To enable or disable PFC, perform the following steps.
1. Select the DCB tab on the Switch Administration panel.
2. Select the QoS tab.
3. Select the DCB Maps tab.
4. Under the Priority Group area, enable or disable Priority Flow Control Status option for each
Priority Group ID.
Enabling and disabling FCoE ports
You can enable and disable FCoE Ports individually from the Port Administration panel.
1. Select the FCoE Ports tab on the Port Administration panel.
2. Select the port you want to enable or disable under the FC0E Ports Explorer, or from the list.
3. Click Enable or Disable to change the current status of the port.
You can also enable or disable by clicking Edit Configuration, and selecting Enable or Disable
on the FCoE Edit Configuration dialog box.
