Usage Guidelines
This command is supported only on RUCKUS ICX 7250, ICX 7450, and ICX 7850 devices.
To enable global PFC, symmetrical flow control (SFC) must be disabled.
You must enable PFC globally before you configure it for priority groups. Enabling
PFC on a priority group enables PFC on all the ports.
PFC and 802.3x flow control are mutually exclusive. Configuring the
priority-flow-control command disables 802.3x in both transmit and receive directions.
PFC is not supported at the interface level on
ICX
7850.
The
no form of this command restores the default flow-control settings.
Examples
The following example enables PFC for priority group 2:
device(config)# priority-flow-control enable
device(config)# priority-flow-control 2
