virtualbaudrate

Syntax	virtualbaudrate virtualbaudrate
	undo virtualbaudrate
View	Synchronous serial interface view
Parameter	virtualbaudrate: Baud rate (in bps) to be set, which must be consistent with the
	one configured at the DCE side. It can be 1,200, 2,400, 4,800, 9,600, 19,200,
	38,400, 56,000, 57,600, 64,000, 72,000, 115,200, 128,000, 192,000, 256,000,
	384,000, 512,000, 768,000, 2,048,000, or 4,096,000.
Description	Use the virtualbaudrate command to set a virtual baud rate for the DTE
	interface.
	Use the undo virtualbaudrate command to remove the specified virtual baud
	rate.
	When working as DTE, the serial interface determines its baud rate through
	negotiation with the DCE side. The virtualbaudrate command, however, allows
	you to configure DTE-side baudrate manually, but the configured value must be
	the same as the one set at the DCE side.
	After executing the virtualbaudrate command, you need to shut down and then
	bring up the interface (using the shutdown command and the undo shutdown
	command) for the new setting to take effect.
n	■ Configure the baudrate command at DCE side and the virtualbaudrate
	command at DTE side (only when the interface is operating in synchronous
	mode). Avoid configuring the two commands at the same end of a link.
	■ At DCE side, the display interface command displays the baud rate of the
	interface; whereas at the DTE end, the command displays the virtual baud rate
	of the interface.
Related command:	baudrate.
Example	# Set the virtual baudrate of DTE interface Serial 1/0 to 19,200 bps.
