ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
Switching Commands 3-204
v1.0, November 2010
To enable priority-based flow control for a particular CoS value on an interface:
Ensure that VLAN tagging is enabled on the interface so that the 802.1p priority values are
carried through the network.
Ensure that 802.1p priority values are mapped to FASTPATH CoS values.
Use the datacenter-bridging priority-flow-control mode on command to enable priority-based
flow control on the the interface.
Use the datacenter-bridging priority-flow-control priority command to specify the CoS values
that should be paused ("no-drop") due to greater loss sensitivity. Unless configured as "no-
drop", all CoS priorities are considered nonpausable ("drop") when priority-based flow control
is enabled.
When priority-flow-control is disabled, the interface defaults to the IEEE 802.3x flow control
setting for the interface. When priority-based flow control is enabled, the interface will not pause
any CoS unless there is at least one no-drop priority.
datacenter-bridging priority-flow-control mode on
Use this command to enable priority-based flow control on an interface.
no datacenter-bridging priority-flow-control mode
Use this command to disable priority flow control on an interface.
datacenter-bridging priority-flow-control priority
Use this command to specify the priority group(s) that should be paused when necessary to prevent
dropped frames; i.e., the group to receive priority flow control. This configuration has no effect on
interfaces not enabled for priority flow control.
