UpaaeRouter1#show ip interface brief // check how may interfaces you have, note serial interface numbers Network engineer must know functionality of routerРІР‚в„ўs 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 routerРІР‚в„ўs 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.Р”В«efore 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 routerРІР‚в„ўs serial interface is required when you want to use a back-to-back WAN connection.
