Clockrate & Bandwidth
|
|
|
| Is clockrate and the bandwidth the same thing on cisco routers?
I know bandwith is set on DCE end,
is clock rate on the DTE end? | |
|
| Clockrate is set on the DCE device | |
|
| clock rate is used for the "clocking" between DTE and DTE devices if no clocking device exists (DCE). bandwidth is for determining path cost I believe.

These two are not the same. Clock rate is set on the DCE and controls the rate of clocking pulses on the cable between the DTE and DCE.
Bandwith is set manually on an interface as an advise to routing protocols that uses bandwith in their metric computation (e.g. IGRP). Note that what you set here does NOT affect the real bandwith of the line. You can in fact cheat the routing protocol into believing the line is faster or slower than it actually is. You will not even see a warning if you use the wrong number.
Random tip: Clock rate is specified in ticks per second, e.g. 64000 wheras bandwith is specified in kps, e.g. 64k.

| The bandwidth is the amount of data (usually expressed as kb/kilobits or Mb/megabits) that can be transmitted per unit of time (second). The values you see for different media/protocols (Ethernet 10Mbps, ISDN/B 64 kbps, etc.) represent that maximum that can be achieved.
Extra note for the clock rate: you'll see it only on synchronous lines (ever heard of clock rate on Ethernet  ).

|
| i'm off to take the test,
hope i pass.but before i go
Clockrate and Bandwidth are both set on DCE end | |
|
| Great answer Terje!
