Hi Friend,

Yes this statement is wrong!!

As I mentioned in my first post divide the networ device in 2 groups.

Switch and Router belong to different group so need a straight through cable and if any device need to be connected in same group needs a cross over cable.

HTH, if yes please rate the post.

That is correct - a straight-through cable is what you need.

Hope that helps - pls rate the post if it does.

Hi Friend,

As Paresh already confirmed you the right answer but I will tell you the trick to remember this.

Divide the major network devices in 2 groups

Group A (Router,PC,Server)

Group B (Switch,Bridge,Hub)

Whenever you have to connect devices in 2 different groups use straight through cable and when you have to connect any devices in same group use corss cable.

HTH, if yes please rate the post.

please let me know which router ur using. As far as i know majority of routers work with cross cable.

Re: what cable to connect the fa0/0 port on a router to the fa0/

Hi Friend,

No router needs a corss cable to connect to switch. They always need a straight cable.

Yes if router has a switch module and you connect via switch module to switch then you need a cross cable.

But talking about a ganeral router with its layer 3 interface when connected to switch need a straight cable for sure.

Re: what cable to connect the fa0/0 port on a router to the fa0/

that is the big problem: in the exam, the question just stated 'what cable would you use to connect the fa0/0 port of a router to the fa0/0 port of a switch?' they did not state on which particular router. so what would your answer be to such an ambiguous question? straight-through or crossover?

the numbering "fa0/0" on a router logically precludes a switch module on a router, as it would be something like "fax/y/z" so you can assume a router port connecting to a switch port, which will always be a straight through.

so in effect, the statement below is wrong?:

"The fastEthernet ports on a router and a switch are both RJ-45 ports. It means we have similar devices on both ends. So a crossover cable must be used here."

apparently the above statement is wrong!
