If your router is facilitating a CSU/DSU, which of the following commands do you need to use to provide the router with a 64000bps serial link?

[A]. RouterA(config)#bandwidth 64
[B]. RouterA(config-if)#bandwidth 64000
[C]. RouterA(config-if)#clock rate 64
[D]. RouterA(config-if)#clock rate 64000

Answer: Option D


The clock rate command is two words, and the speed of the line is in bps.

A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts a digital data frame from the communications technology used on a local area network (LAN) into a frame appropriate to a wide-area network (WAN) and vice versa. For example, if you have a Web business from your own home and have leased a digital line (perhaps a T-1 or fractional T-1 line) to a phone company or a gateway at an Internet service provider, you have a CSU/DSU at your end and the phone company or gateway host has a CSU/DSU at its end.

Can anyone tell that why "clock rate 64000" command is used, why not "bandwidth 64000"?

Clock decided to speed of link.
