Hello,
I ordered a set of hardware that came with CBT videos; however, the videos they sent do not exactly match the hardware and I'm stumped.
I have 3 routers:
2610XM: Indianapolis
2620:New_England
2610:Seattle
Indianapolis connects to New_England with a WIC-1DSU-T1
Indianapolis connects to Seattle with a WIC-1T
The interfaces are up on all three devices and so are the protocols. The videos are of 2500 series routers and they only use the WIC-1T card. When I try to set the clock rate for the s0/1 on New England to 1000000 like the video suggest I get an error "this command only applies to DCE interfaces". Do I not need to set this on the WIC-1DSU-T1 interface?
Also,
Whenever I issue router rip and try to set network such as:
router rip
network 10.0.1.0
network 10.0.10.0
network 10.0.20.0
the network won't save on any of the devices. If I show the running-config it shows network 10.0.0.0 I've tried saving the config directly after exiting outt of the config mode, but still only 10.0.0.0
Thank you all for your time

Hello Adama,
1)The clock-rate needs to be enabled on the DCE end.
Each serial cable has two ends, DTE and DCE, the clock rate goes over the DCE side
To determine witch end has the DCE do the following
show controllers serial x/x
Interface Serial1/0
Hardware is PowerQUICC MPC860
DCE V.35, clock rate 20000......
Example:
2)
router rip
version 2
no auto-summary
network 10.0.1.0
network 10.0.10.0
network 10.0.20.0

Thanks Julio,
I did that with the serial cable S0/0 interface usingg the WIC-1T card and it worked fine. It just doe not work on the S0/1 interface on the same router using the WIC-1DSU-T1 card. That card does not use a serial cable but the T1 crossover cable. I will try your router rip and see if that changes anything.

Hello,
If it's not a serial cable of course you cannot set that on the interface
Sure let me know

Hello Adama,
WIC-1DSU-T1s are not like WIC-1T for they always work as a T1. You do not need to use the clock rate command when you are configuring a WIC-1DSU-T1 for the configuration will be different. Please check the following link for further information on how to configure that card:
http://www.cisco.com/en/US/products/hw/modules/ps3129/products_tech_note09186a0080093d70.shtml
Interface serial 0/0 service-module t1 clock source internal service-module t1 timeslots 1-24 speed 64 service-module t1 framing esf service-module t1 linecode b8zs ip address 10.1.1.1 255.255.255.0 encapsulation ppp
no shut
If you use timeslots 1-24, the serial will work as a full T1 but this is the default.
It is also useful to mention that one end of the T1 circuit should use clock source internal while the other end uses line.
You can also check the following link on clocking for a back-to back T1 circuit:
