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 ...
Where and why is clock rate used?
In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses , which are used to synchronize the operations of its components, and is used as an indicator of the processor’s speed.
What is the clock rate of serial interface?
By default, the serial interface has a clock rate of 16.384 MHz .
What is clock rate on router?
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?
“Clock Rate” is the physical rate, at which data are transmitted . It’s your actual speed. “Bandwidth” command has nothing to do with your physical speed. This is a parameter used by some routing protocol to calculate a routing metric.
Why clock rate is used in router?
Clock rate is to be used in DCE in serial link to configure the clock speed for the link . ... When connecting two routers together with a serial cable, one of the routers needs to host the DCE (Data Communications Equipment) side of the cable, and the other will host the DTE (Date Terminal Equipment) side.
What is a good processor speed?
More cores can help achieve a higher quality gaming experience. ... A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it’s more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks.
Which memory type holds the full IOS image for the router?
The Flash memory contains the full Operating System Image (IOS, Internetwork Operating System). This allows you to upgrade the OS without removing chips. Flash memory retains content when router is powered down or restarted.
Which mode the command clock rate is used?
This can be done by using the “clock rate” command, from the interface configuration mode . To find the possible clock rate values, get the command help by using a question mark after the “clock rate” from the serial interface configuration mode, as shown below.
How do I create an interface DCE?
- In configuration mode, go to the [edit interfaces interface-name ] hierarchy level: [edit] [email protected] # edit interfaces interface-name.
- Configure the dce option to respond to Frame Relay status enquiry messages. [edit interfaces interface-name ] [email protected] # set dce.
Is router DTE or DCE?
The device that provides clocking, typically the CSU, is considered to be the data communications equipment (DCE). The device receiving clocking, typically the router, is referred to as data terminal equipment (DTE) .
Which command will show you the IOS version running on your router?
Which command will show you the IOS version running on your router? Explanation: The best answer is show version , which shows you the IOS file running currently on your router. The show flash command shows you the contents of flash memory, not which file is running.
What is one way in which STP protects a redundant Ethernet network?
What is one way in which STP protects a redundant Ethernet network? RSTP adds some concepts to STP that enable ports to be used for a role if another port on the same switch fails.
What is high bandwidth?
Bandwidth, typically measured in bits, kilobits, or megabits per second, is the rate at which data flows over the network. Because this can make the network feel faster, high bandwidth networks and connections often are called “ high-speed “. ...
What is bandwidth clock?
For example, if the clock frequency is 100 MHz, the bandwidth of the signal is about 500 MHz. If the clock frequency is 1 GHz, the bandwidth of the signal is about 5 GHz. This is a generalization and an approximation, based on the assumption that the rise time is 7% of the clock period.
What is the default bandwidth of serial DCE ends?
In the case of a serial interface, the default bandwidth is 1,544 K (or a full T1 circuit).
