Hello All, How does the delay value configured on interfaces affect the network? Regards, Geo. Top Rated Answers. Geo John, As Daniel said I just lab it up like serial path configured with lower delay and fastethernet having higher delay, and verified that eigrp prefer serial path to the destination due to the lower delay on serial interfaces. All Answers. Hello John The below link might be helpful delay setting on interface, what does it mean?
John, Delay is a value that shows how much time it takes to transmit the packet on the link. Geo John, Hello All, How does the delay value configured on interfaces affect the network? Regards, Geo How does the delay value configured on interfaces affect the network? Basically there is a lot to this. But the straight and easy to understand answer is: This value is used by other protocols Routing protocol EIGRP to calculate it's metric. Thanks Juel, Sergey and Daniel for your time. Kindly share your thoughts.
John, I don't think physical distance is really a factor in the delay metric. From ccie v5 ocg: Delay Metric Component The delay is a static metric assigned to each interface using the delay interface command. This metric component estimates the serialization delay incurred by the interface. Being a static value not related to any true characteristic of an interface, the delay metric component of an interface can be seen more like an average delay incurred by the interface for typical traffic.
I think our friends already answered the question, I would like to say that delay should be change with much care. Thanks everyone, Its very clear now. Log In to Answer.

Another method was to do more complex signally, sometimes using analog rather than digital - see modem signally across a medium with a broad bandwidth.
Modern Ethernet, FE and gigabit Ethernet, technically, for pretty much the same basic technology, although each of those generations supporting 10x the capacity of the prior generation. They too are actually, more or less, serial usually much faster than the old "serial" , usually on copper, might be on fiber. However, older Ethernet, on copper medium, didn't use the same copper wiring generally used today which also, BTW, "better" copper is needed to support higher bandwidth ["speed"] copper too.

Differentiate between Fast Ethernet, Gigabit , Serial and optical. Your keyboard and mouse are one-way devices that only require a serial interface and line. Inside your computer, much of its circuitry supports bits being moved around in parallel.
Serial communication between your PC and the modem and other serial devices adheres to the RSC standard. Conventional computers and their programs operate in a serial manner, with the computer reading a program and performing its instructions one after the other. Considered to be one of the most basic external connections to a computer, the serial port has been an integral part of most computers for more than 20 years.
Although many of the newer systems have done away with the serial port complvcely in favor of USB connections, most modems still use the serial port, as do some printers, PDAs and digital cameras. Few computers have more than two serial ports. Essentially, serial ports provide a standard connector and protocol to let you attach devices, such as modems, to your computer. In this edition of How Stuff Works , you will learn about the difference between a parallel port and a serial port, what each pin does and what flow control is.
