None

Description

By default, no clock rate is configured for any serial devices. This command specifies the bit rate for DCE serial devices in bps. Possible values for bps are 1200, 2400, 4800, 9600, 19200, 38400, 56000, 64000, 72000, 125000, 148000, 500000, 800000, 1000000, 1300000, 2000000, and 4000000.

This command is most useful for connecting routers back-to-back in a lab setting. In this case, the command is required only on the DCE end of the link. You usually don’t need this command when connecting to a WAN service because the network provider provides the clockings.
