What is clock rate command?

clock rate (interface ATM) To configure the clock rate between a WAN interface card (WIC) and the serial communication controllers (SCCs) that are used by the WIC, use the clockrate command in interface ATM configuration mode. To disable the clock rate setting, use the no form of this command.

What is a serial DCE cable?

DTE stands for Data Terminal Equipment, and DCE stands for Data Communications Equipment. DTE is typically either a dumb terminal or the serial port on a computer/workstation. Therefore, a straight through “one to one” cable is all that is necessary between a modem and a standard DTE serial port.

What is clock rate in networking?

The clock rate serves to synchronize the receiver on the other side of the link. Each clock pulse signals the transmission of a bit. Note that it is mainly used in lab setups. In the real world, network providers almost always deliver the clock signal.

What is clock rate and bandwidth?

When you set the clock rate for a serial interface, you are setting the speed of the interface,in other words, actual rate of data transfer. Bandwidth is the value that you allocate to the link at DTE site to help with routing decision and QOS.

How to calculate clock rate on a DCE interface?

router(config-if)# clock rate 64000 (represented in BITS per second) If you try use the clock rate command on the DTE interface you will receive the following error message “This command applies only to DCE interfaces” To identify which end of the cable has been plugged into a Cisco router, you can also use the command “show controller”.

What does clock rate mean on a serial port?

With a serial connection you typically have two ends, which are DTE and DCE. DTE would be Data Terminal Equipment and DCE would be Data Communications Equipment. The DCE end will provide the clocking. So if on the other end is a 64kbps link you would enter your ‘clock rate’ command to specify this in bps.

What’s the difference between serial DCE and DTE cable?

The difference between the two cables in packet tracer is just which side you click first: With the DCE cable, (red zigzag with clock) the side you click first will be the DCE, the second will be DTE With the DTE cable (red zigzag no clock) the side you click first will be DTE, the second will be DCE

What’s the difference between serial and DCE in Cisco?

First of all, serial technologies, interfaces and cables are thing of the past. you should not be tested on any serial tech on any Cisco exams (last exam revision Voice CCIE lab may use frame relay -not sure after Feb24 change). Router is DTE and ISP with DCE provides clocking; so, you always had DTE cable end at your place while ISP had DTE.
