Note: In Cisco packet tracer two routers are connected by serial cable and you can set clock rate on any router according to your preference, this way one router will act as DCE and the other as DTE. The clock rate command sets the rate in bits per second on the router that has DCE cable plugged in, the IOS accepts the command, if DTE cable is plugged in, the IOS rejects the command.

Now that you have known the difference between DTE and DCE equipment we will go directly to the commands for setting clock rate on any router. Equipment or devices which provide clocking to other devices are known as DCE devices. The DCE equipment may be an integral part of DTE. The equipment or a device which performs signal conversion and coding function and located in between the communication line/ communication medium and DTE are known as DCE. Network engineer must know functionality of router’s interfaces as DTE and DCE, it is also very important for cisco ccna students who are preparing for ccna exam. Whenever two routers are connected one will act as DTE and the other will act as DCE, the decision is up to the network engineer to specify each router as DCE OR DTE.

It is important to know the process of setting clock rate on router’s serial interface from CCNA exam perspective and network labs, but in real world almost every network provider delivers clock signal which does not require setting any clock rate on router at the customer end.īefore jumping to the commands for setting clock rate you should know the difference between DTE and DCE. Setting clock rate is important for synchronization as each clock pulse signals the transmission of a bit. When two routers are connected one must supply the clocking for communication with each other. Setting clock rate on a router’s serial interface is required when you want to use a back-to-back WAN connection.
