To configure the clock rate for the hardware connections on serial interfaces such as network interface modules (NIMs) and interface processors to an acceptable bit rate, use the clock rate interface configuration command. Use the no form of this command to remove the clock rate if you change the interface from a DCE to a DTE device. Using the no form of this command on a DCE interface sets the clock rate to the hardware-dependent default value.

When the interface is functioning as a DCE device
The interface is configured as a DCE device.
The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.

1. The command show controllers serial [interface number]can be used to determine whether your serial interface is a DCE or DTE interface. An abbreviated listing of the displayed results for the show controllers serial 0 command is shown. The Serial0/0 interface is a V.35 DCE cable. This command should be used when you have an RJ-45 connection.2. The V.35 cables are typically labeled to indicate whether they are a DTE or DCE cable.3. Inspect the end of the V.35 cable to determine whether it is made (DTE) or female (DCE)
