priority-flow-control enable
Enables priority flow control (PFC) globally.
Syntax priority-flow-control enable
no priority-flow-control enable
Command Default PFC is globally disabled.
Modes Global configuration mode
Usage Guidelines The no form of this restores the default flow-control settings.
To enable global PFC, symmetrical-flow-control must be disabled.
You must enable PFC globally before you configure it for priority groups.
Priority flow control and 802.3x flow control are mutually exclusive; therefore, configuring the priority-
flow-control enable command disables 802.3x in both transmit and receive directions.
Examples The following example shows how to enable PFC.
Device(config)# priority-flow-control enable
