Configuring FrameRelay lab but having to set clocking on Spoke Routers? Help?

ciscoman2012

Hey guys,

I'm trying to run through some Frame Relay labs but everyone isn't working because I'm not able to set the clocking on the FR switch.

For example, I have a 4 NM A/S card in my FR Switch and then DB60 -> Smart Serial (DCE) cables. The only way I can hook it up is to have the DB60 (DTE) plugged into the FR Switch and the SS (DCE) end plugged into the spoke routers.

How should my commands differ in order for the FR lab to work?

Would each serial interface on FR Switch still have the frame-relay intf-type dce command, etc.?

Or do I need to go out and buy all new serial cables lol.

PS: Don't worry about the random host and switch in my topology...it's been a long day.

Well for now I'm just going to use wic 2Ts in my FR router so that I can have my remote routers as DTEs.

I'm going to lab a little later once I get some patience back from earlier..LOL

ciscoman2012,

I'm using a 3620 for my frame relay switch and I am using it as the clock source. All of the DB60 back to back serial cables have the DCE end connected to the 3620 and the DTE end connected to the adjacent routers.

Here's the config I used for each of the serial interfaces.

frame-relay switching
!
interface Serial0/0
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay lmi-type ansi
frame-relay intf-type dce
frame-relay route 100 interface Serial0/1 200

I can see where your coming from with this

I have the same issue, I have 2x wic 2t for my frame relay switch, and wic 1ts for my spoke routers. My problem is that the cables i have are smart serial to serial, with the DCE printed on the Serial end. So the DCE end of the cable ends up on the spoke routers.

so do I set the clocking on the spoke routers instead of the frame-relay switch?

I'm going to config it all up today, will let you know if and what works

In my studies, clocking is done on the Frame-Relay switch, not on the spoke routers.

I got my setup running fine plugging the DTE Cables into the Frame Switch. And the DCE end of the cables into the spoke routers.

configs as below

Spoke Routers x3

interface Serial1/0
ip address 10.10.12.3 255.255.255.240

Frame Relay Switch:
