shellFlowControlEnable

Enables XON/XOFF flow control on the console serial port.

SYNOPSIS shellflowcontrolenable

DESCRIPTION Use this command to enable XON/XOFF flow control to the shell task. Flow control is disabled by default.

Because this command changes the flow control on the console serial port, it must be executed from a

session that is logged in from the console serial port. This command cannot run from a Telnet session.

This setting is saved in the configuration database; therefore, it is persistent across reboots and power

cycles.

NOTES On dual-CP systems, a reboot on the standby CP is required for this command to take effect. No action is

required on the active CP.

If flow control is enabled and if the console output is suspended for an extended period of time, the

switch might reboot. It is recommended to disable the flow control, using shellFlowControlDisable.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in

place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

details.

OPERANDS None

EXAMPLES To enable flow control:

switch:admin> shellflowcontrolenable
