What type of interface that needs the clock rate command?
serial interfaces
In serial interfaces you need to make sure that clock rate and bandwith do match (changing clock rate does not automatically changes bandwith) Otherwise it could happen that your routing protocol does not take into account a link or sets the best route through the wrong link, because of bad settings in bandwith …
What is clock rate command?
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 .
How do I find the DCE interface?
If you can see the DTE/DCE cable, you can tell by looking which router has the DCE interface connected to it – the letters “DTE” or “DCE” will either be molded into the connector itself, or if it’s an older cable there should be a little piece of tape on the cable that tells you what the interface type is.
What is DCE and DTE in Cisco?
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. DCE is typically a modem, DSU/CSU, or other piece of data communications equipment, hence the names.
Why is clock rate used?
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.
How do I configure a DCE interface on a Cisco router?
To configure the router to be DCE:
- In configuration mode, go to the [edit interfaces interface-name ] hierarchy level: [edit] user@host# edit interfaces interface-name.
- Configure the dce option to respond to Frame Relay status enquiry messages. [edit interfaces interface-name ] user@host# set dce.
What is DCE and DTE interface?
Data Terminating Equipment (DTE) and Data Communication Equipment (DCE) are used to describe two different hardware groups. The term DTE is used primarily for those devices that display user information. It also includes any devices that store or generate data for the user.
What is DCE in data communication?
Are routers DCE or DTE?
In this example, the router, which is a DTE device, is connected to a CSU/DSU or modem, which are DCE devices. Because the serial devices are DCE, you should use a DTE cable to connect the router and the CSU/DSU or modem.
What is clock rate on Cisco router?
How do I find the DCE on my router?
Each router is a DTE by default. The cable decides which end to be DCE or DTE and it is usually marked on the cable. The picture below shows back to back cable. If is not marked, we can use the Cisco IOS show command “show controller” command to determine the interface is DTE or DCE.
