| After most of the year doing my MCSE I feel it's time to get to grips with Cisco after my next MS exam.
My question is this:
I have one 2503 router and a 2924 XL-EN switch. I intend to purchase another 2503 router and I have been told I will need to connect the one to the other for access lists etc.
I already have a DCE-DTE cable but will I need another DCE-DTE cable or any other type of cabling before I start configuring my home lab to prepare for the exam?
Many thanks in advance.

| dce/dte crossover cable is used to connect two router serial interfaces, not a router to a switch.

| Sorry if you found the post misleading or if I did not explain myself correctly.
I intend to purchase another 2503 router and I need to know if I will need any other cables besides the DCE-DTE to connect the two routers via the serial interface.
Thanks for the reply.

| That's all you need to connect the two routers from serial to serial.

| I read the routers serial interface can produce clocking, would you still need same cable to connect two routers serail interfaces??
reply appreciated | |

| One of your 2503s will produce the clock for your serial link (this will be your DCE device. The other 2503 will be your DTE device. Go to the Cisco site and search for "Back to Back". They have some excellent sample configurations for your viewing pleasure. You can either setup for Back to Back Frame Relay, PPP or HDLC. Since you are just getting started I would go with the HDLC to make sure your serial link is up and running before going to frame relay... | |

| Thanks for your help Yankee.
Does anyone have a link that explains the concepts in greater detail?
Thanks in advance.

Anyone else?

| you will use a DCE-DTE serial cable to connect 2 router's together
One router will be your DCE router which you will set the DCE timing enable on, this router will also have the DCE end of the DCE-DTE cable,,,
The other router that has the DTE side of the cable will not need the timing enabled.
This is all you need to connect 2 router's together,,
btw= you will need a roll-over cable made from Cat-5 to connect to the router (console port) from your workstation to do any router configuration... | |

| Hi CoffeeFreak,
I've got the console kits etc. so that's not a problem (Thanks anyway) DCE-DTE, The DCE indicates the clock but what does the DTE denote?
What's the difference between Back Frame Relay, PPP (Point to point?) and HDLC?
Why test HDLC before going into frame relay?
Please remember I'm still new to most of this but if anyone can provide a link for the above I would be greatful.

| You would want to experiment with HLDC point to point first because it is basically a direct connect between two endpoints and you can do that as previously described with a DTE/DCE crossover cable. To play with frame relay one router must simulate a frame-relay switch and is a bit more complicated.
