Command Reference
virtualbaudrate
Purpose Use the virtualbaudrate command to set a virtual baudrate for the DTE
interface.
Use the undo virtualbaudrate command to cancel the specified virtual
baudrate.
Syntax virtualbaudrate virtualbaudrate
undo virtualbaudrate
Parameters virtualbaudrate
Specifies a baudrate in bps, which must be consistent
with the one configured at the DCE side and can be
1200, 2400, 4800, 9600, 19200, 38400, 56000,
57600, 64000, 72000, 115200, 128000, 384000,
2048000, or 4096000.
Example Set virtual baudrate of a DTE interface to 19200.
[3Com -Serial4/0/0] virtualbaudrate 19200
Cancel the specified virtual baudrate of the DTE interface.
[3Com -Serial4/0/0] undo virtualbaudrate
View This command can be used in the following views:
■ Synchronous Serial Interface view
Description When working as DTE, the serial interface determines its baudrate 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.
To validate the configured baudrate value for routing, execute the shutdown
command and then the
undo shutdown command on the interface.
■ 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, you can use the display interface command to view the
baudrate of the interface; at the DTE end, you can use the
display interface
command to view the virtual baudrate of the interface, if it is configured.
