Modes Global configuration mode
Usage Guidelines The no form of this restores the default flow-control settings.
By default, the system runs in tail-drop mode, with all ports honoring 802.3x flow control and disabling
802.3x transmit. The symmetrical-flow-control enablecommand enables transmission of 802.3x
pause frames.
Configuring the symmetrical-flow-control enable command changes priority-to-PG mapping.
You cannot configure the symmetrical-flow-control enable command if the priority-flow-control
command is enabled.
If the symmetrical-flow-control enable command is not enabled, you cannot configure the flow-
control generate-only or the flow-control both commands in interface mode.
Examples The following example shows how to enable SFC:
Device(config)# symmetrical-flow-control enable
The following example shows how to enable all priorities to send the IEEE 802.3x pause:
Device(config)# symmetrical-flow-control enable all
The following example shows how to enable SFC for Generate-only mode:
Device(config)# symmetrical-flow-control enable
Device(config)# flow-control generate-only
The following example shows how to enable SFC for both Honor and Generate-only mode:
Device(config)# symmetrical-flow-control enable
Device(config)# flow-control both
