configure cisco router

Hey all router gurus.

I have got this cisco 3660 router. It has got 6 T1 slots.. I need to configure one of them.
What I am planning to do is to configure that T1 interface (giving static IP address) and then connect a T1 line from it to an Adtran netvanta router (1224R) . Then  a computer would be connected to that  Adtran.

As of now , I would like to configure one T1 interface of the cisco.. Possibly giving an ip address 172.16.80.10..

I would like to know the instructions to do the same. I would be telneting to the router ..

Thanks.

can you post your existing config (just the controller and serial interfaces)
It's pretty simple:
  router(config)#controller t1 4/2
  router(config)#channel-group 1 timeslots 1-24
  router(config)#no shut
  router(config)#interface serial 4/2:1    <== controller 4/2: channel-group 1
  router(config-if)#no shut
  router(config-if)#ip address 172.16.80.10 255.255.255.0 <== apropriate mask
  router(config-if)#encapsulation ppp
  router(config-if)#exit
  router(config)#  

What routing protocol are you using? you need to add this interface subnet to the networks list..
Do you need help with the Adtran side, too?

Thanks for asking Lrmoore. I have already configured that Adtran.

Could you tell me more on what is the existing config you are asking ?

Can you get that from my previous question. I am at home and donot have access to the router now.. but If we cannot get it from the other question , then I can give only tommorrow morning ..

Let me back with what I am trying to achieve by configuring this.. It will take me few more minutes to write up here... brb
Looks like we had the other post edited. If you can follow my first post, that's really about all there is to it. Just use the appropriate controller slot/port

Need the part from the existing config, starting with 'router ?????'

We have this cisco router .. 6 T1 cards , basically 12 ports.
We have 2 T1 cards already configured and working great.. Thanks to your help on fixing one of those ..

So the connection from one of the Cards is


CISCO router (T1 card ) <--------------TI line -------------> Smart Jack (Our location)  <---------------T1 line ------------->
Smart Jack (remote location)  < ----------T1 cable ---------> Adtran router <-------- Cross-Over cable ---------> Polycom video equipment..  

The above setup works great..

Now, I have this Adtran router (different one , ofcourse) which I had configured.. Instead of going to the remote location to test it , I want to test it in my location itself..

So what I plan to do is as follows

CISCO router (3rd T1 Card as 1/0,1/1,2/1 and 2/1 are already configured..)    <----------T1 cable ---------> Adtran router <----------- Cross-over cable  ---------> Polycom unit..


Will the above work doing that by-passing those smart jacks etc ?

I assume that the leased line T1 goes through a provider's frame network in which case you're using their clock (stratum 4).  Most of the Adtrans have a stratum 2 clock at best.  So, while it may "work" for design purposes, I wouldn't expect lengthy tests to be accurate as clock slips will create errors on the ckt.
You'll need to set the clock source on the 3660 for the link, and you'll need a T1 crossover cable crossover 1-4, 2-5 to set this up in the lab

router(config)#controller t1
router(config-if)#clock source internal
router(config-if)#clock rate 154000

Lrmoore,

So you are saying about the cross over cable between the T1 card in cisco router to the Wan port of the Adtran , is it ?

So instead of a  T1 cable , I would be using a cross over because it is between 2 routers, Am i right ?
Yes, but a T1 crossover, not the same as a Ethernet crossover. Pin 1 crosses to pin 4, pin 2 crosses to pin 5..
Easy way to make one is to snip one end off a cat5 cable, swap the blue and orange pair in a new end..
OK Thanks.. I would have to work on it tommorrow and see and will post you back if I am successful
OK. I'll be away all morning tomorrow  (going to a cisco systems new product seminar)...
Is that seminar in NC ?  
No. In Birmingham, AL..
Curious to know if You got my emails ..  
Probably not. I've got a filter on this account. With few exceptions, anything NOT from EE goes straight to deleted folder..I don't usually look at them. I'll keep my eye out, though..


LOL !!. Probably , you missed 3 or 4 of my emails then.. I replied to the email that you sent me few days back.. Nothing important tho..
Lrmoore,

Just made the T1 crossover cable..

Instead of configuring the new interface in the CISCO , I am using the already configured interface since I am doing the testing..

I connect the T1 cross over from CISCO to Adtran.. Light comes up fine in CISCO and NO alarms.
Now in the Adtran router , I see the WAN light going green.. Looks good.
I connect a patch cable from one of the 24 ports of the Adtran to my computer.  

Can ping my computer (just loopback)
Can ping the ethernet port of Adtran
Can ping the WAN port of the Adtran..

That is it.. I cannot ping the Cisco router..

Now , what I would like to know is should I be doing these config changes inside the CISCO router

*******
router(config)#controller t1
router(config-if)#clock source internal
router(config-if)#clock rate 154000
********
even to make the connection between CIsco and Adtran..

I have got a spare Adtran , configured it and still no go.. I wish I had one of those 3205 Netvanta .. I donot have it ..
This router/switch never has worked so far.. Confirmed with the Adtran customer support that the configuration , I have got inside it is correct.. So no configuration problem..

Now the problem could be the T1 cross cable I made.. See this is how I made..

One end                                              Other end  

1  White orange  <----------------------->  Blue                  1
2  Orange           <----------------------->  White Blue         2

4  Blue   <---------------------------------> White Orange      4
5  White Blue  <---------------------------> Orange              5

Is this fine ?

SR
Now I go inside the Cisco router and do enable

router(config)#  controller t1 2/1
router(config-controller)# clock source internal
router(config-controller)# clock rate 154000  (when I type this it is saying invalid character and goes back to prompt)

Now when I say "show run", it gives

********************

As you can see above 2/0 is operational and I am working on 2/1..  

I guess I cannot do the testing with Adtran because I have not set the clock rate

and

I cannot connect to the remote site as you can see there is this " clock source internal " added in the above configuration.
How do I Undo that so that I can connect to remote site and what extra step I need to do to connect to adtran ?

SR
Crossover cable looks OK.
You need the clocking on one end. Suggest the Cisco side

What speed options do you get with

router(config)#  controller t1 2/1
router(config-controller)# clock source internal
router(config-controller)# clock rate ?   <== use the ? liberally to access the on-board help system..
Set it for whatever is closest to full T1 rate..

To undo the "clock source internal"

router(config)#  controller t1 2/1
router(config-controller)# clock source line

Since this is the default setting, it may  not show up with "show config"


Ah.. I get it . I first on thursday when I get access to the router , I should do clock source line so that atleast I donot disturb the original connection to that remote site. Well at this moment there is no equipment there so fine..

As Far as I remember , When I did "clock rate ? " , it said something equivalent to invalid command..

Here is my previous configuration that I used in my previous question..

PS: Framing is ESF, Line Code is B8ZS, Clock Source is Line.   is because this is the previous configuration before I did this clock command so I guess it is still showing "Clock Source is Line"...

Looks like you have the exact same issue that you had before:

Serial2/1:1 is up, line protocol is down  <==
  Hardware is DSX1
  Internet address is 172.16.89.1/28 <== What is the test Adtran set to? This must be the same subnet

> Possibly giving an ip address 172.16.80.10.. <== is the Adtran set to .80.9 ?

What is the LAN subnet on the Adtran? 172.16.81.0 /24 ?
Add a route to it also:
   ip route 172.16.81.0 255.255.255.0 172.16.80.9
No Lrmoore. That line protocol is down because that configuration I tool before my previous issue was solved. It is up now..
Sorry for the confusion..

The IP address I am using is all 89.1.. THis is because as I said before I am using the same interface card which I used in my previous question ..

Here are some info

Adtran WAN port  172.16.89.14
VLAN port : 172.16.89.17
and subnet mask = 255.255.255.240 ..

When I went inside the configuration  of the adtran  router , If I am not mistaken the IP route inside was
172.16.89.16   255.255.255.240

I need to check IP route one more time...

I am giving the config here which I had given in my previous question (well it is not there  now)

On the Adtran, make sure you have a default:
   ip route 0.0.0.0 0.0.0.0 172.168.89.1

What's the status now of "show interface serial2/1:1" ?
Once you set the timing on the controller, you should be good to go....


Oh gosh.. I am at home right now and no access to router.. I am going to think about this all nite.. oh man..

I guess everything looks good except that I need to check that timing on the controller..
I also know that ip route  0.0.0.0 0.0.0.0 172.16.89.1 was added in the router...

Now the only thing is about that "clock rate"..

From the above comment of mine
Comment from sunray_2003
Date: 10/26/2004 04:35PM EDT

Can I not get the timing of the controller ??

SR
Whenever you set up back-to-back WAN connections in a lab, you must provide T1 clocking on one end or the other. You can set the clockrate to whatever you want and emulate a lower speed link, but it is best to use something closest to a T1 154000, 153600, or even 2000000
You are telling the controller what clock rate to use for the "internal" timing.

SO first thing I would do is to check all the above suggestions are fine in both cisco and adtran.

then will check "show interface of 2/1" and then provide you the result..

I am confident that should work..  Thanks so much for hanging with me..
One more thing.. Will be online this evening.. If yes, I am going to go to my office and do the setup again and post back..
I cannot wait to get this resolved (well I am like that).... It should be in my office and can do all the setup in the next 30 mins
will be online = will you be online
Wife is getting annoyed, so I must jump off and spend some time with her and have dinner....

I'll check back later...

any approximate time you would be back..  I can go to office anytime ..
Most likely around 8 pm Central time...
oops. I was too fast to say I can go to office anytime.. LOL.. 9 EST is kind of late and moreover, that is my dinner time..

I will do the tests tomm then.. Around 8 am or so I should have the show interface result here.. will post back tommorrow
You should try the "clock rate" command on the serial interface that gets created by the controller. I've never seen a "clock rate" inside a controller configuration before.

-Eric
Good catch, Eric. I don't have anything with controller interfaces in my lab, but it certainly does work under the serial interface if using WIC-T1-DSU..
Also, I noticed that if I set the clockrate to the "default" 2000000, then it does not show up with "show config"
Perhaps if you simply set the controller to clock source internal, unless you can change it to something else it will use that default clock rate?

Any luck today?

I forgot yesterday that it was my off-day today. I will be in office tommorrow. Will report asap tomm..

So you want me to change the clock to internal and then post back with the interface log
Lrmoore,

This might give you problems with a short crossover back-to-back

Just make sure you plug something into one of the switchports to bring VLAN1 up...
Do you have to do the cross-connect on this adtran box for the T1 - ppp? I have a Adtran 3200 that requires it..

I connected a patch cable from one of the switches to my laptop and can get into the web management of the router. SO i guess that part is fine..

Not sure what you mean by cross-connect T1 --ppp.. could you please explain ..
This is my ppp setup on my Adtran NetVanta 3200

Oh.. Yeah I see that cross-connect in our 3205 router..

Not seen in this 1224 router..

Still no luck.. Tested the T1 crossover with a cable tester and looks fine. So no problem with cable..

From adtran , I can only the VLAN port , WAN port.  I cannot ping both the IP of the CISCO or
the IP route 172.16.89.1...

Only thing that I have not done is to put a clock rate.. Other than that I have done all the suggestions..
On the 3660, try (I'm doing this from memory, so liberal use of "?" please..):
  controller T1 2/1
    cable length short

Will the 1224 even take that cross-connect command?
No problem , lrmoore.. I can understand how difficult to have all these in memory.

when i do cable short ?
it gives this

router(config-controller)#cable short ?
  133ft  0-133 ft
  266ft  134-266 ft
  399ft  267-399 ft
  533ft  400-533 ft
  655ft  534-655 ft


Do you want me to put  "cable short 133ft" and see what happens ?

I have not tried putting cross-connect command in 1224 ?  Remember what command to put ?
Also I found that the Adtran has got a cross-connect command

so it is showing when i go inside the switch by enabling

switch(config)# cross-connect ?
<1-1024>

Yes, use "cable short 133"

On the 1224, try this..
 switch(config)#cross-connect 1 t1 1/1 1 ppp 1  
cross-connect rule #1, take T1 1/1 tdm group #1, connect to interface ppp #1
Sorry, Lrmoore.. not worked with this router and hence getting few errors so not sure what would be the next step.

router(config-controller)#cable short 133
% Configuration of Short Cable not permitted in CSU mode

Not sure what needs to be done for the above error ?

*******
In Adtran , I had put this
>> switch(config)#cross-connect 1 t1 1/1 1 ppp 1  

Did give this statement,
>> cross-connect rule #1, take T1 1/1 tdm group #1, connect to interface ppp #1
just to explain that cross-connect statement ?

SR
>just to explain that cross-connect statement ?
Yes....

I don't know what to tell you on the controller config.. that's one thing I don't have access to in  my lab equipment..
If you can't make them work back-to-back, that still does not rule out that they won't work over the "real" wan link..

Any progress after adding the cross-connect sommand?
What is current status of interface ppp1 on the Adtran? "show interface ppp1"

What is current status of "show interface seraial 2/1:1" on the 3660?

We definately have some issues with the slip sec errors on the controller....
How about result of router(config)#controller T1 2/1
                             router(config-controller)#cable ?    Length? perhaps "cable length <short>"???

I think I'm hitting the wall of how much I can help at this point with your back-back setup since I don't have anything of either product at hand to test with.. ( I should have an Adtran 1224 by Nov 8th)...

I set up a back-back Cisco 3640 with WIC-1DSU-T1 crossover cable to Adtran netvanta 3200. Piece of cake, took 5 minutes with no problems, but there must be subtle differences between the module that you have and the 1224..
router(config)#controller T1 2/1
router(config-controller)#cable ?
  long   long cable
  short  short cable

and if i get this

router (config-controller)#cable long ?
  gain26  26db Gain
  gain36  36db Gain

Can the above help here ?
Makes you want to go hmmmmmmm.....

Need to clear these stats:
   router#clear count interface serial 2/1:1

Then try "bouncing" the T1 line...

   controller T1 2/1
     shut
      <wait 15 seconds>
      no shut


from
router# clear count interface serial 2/1:1

gives "unrecognised command"

so i did this

******
router#clear count ?
  Async              Async interface
  BVI                Bridge-Group Virtual Interface
  CTunnel            CTunnel interface
  Dialer             Dialer interface

  Virtual-Template   Virtual Template interface
  Virtual-TokenRing  Virtual TokenRing
  <cr>
  Lex                Lex interface

router#clear count serial ?
  <0-6>  Serial interface number

***********

So shall I give

router#clear count serial 2/1:1

when i put "clear count serial 2/1:1", it asked to confirm and I gave C and it back to prompt , router#

Now I did this to do the bouncing

router#config t
Enter configuration commands, one per line.  End with CNTL/Z.
router(config)#controller T1 2/1
router(config-controller)#shut
router(config-controller)#no shut  <--------------waited for 20 secs  before I gave this
router(config-controller)#exit
router(config)#exit
router#

Now my "show interface serial 2/1:"

Does it look good.. Looks like the counter has changed.. I mean

Will change the clock source and be back
Now I changed the clock source to line on CISCO's 2/1 and when I put "show controller T1", I get this for 2/1

***********************

In the Adtran , changed the clock source from line to internal.
Did a cool restart and still no go..

I will wait.. no problem ..
The adtran as well as the router have poor stratum 2 clocks.  On a point-to-point T1, you're better off going with something like a larscom that provides a stratum 3, an external clock (litterally a device that plugs into the CSU), or engineer the ckt so telco can provide the clock (stratum 4).  Those slip seconds are (obviously) timing slips and there isn't a strong enough clock source for the T1 to time off of.  Make sure that only one of the CSU's is providing clocking and make sure that telco isn't providing it somehow (if they are and you're adding a clock, you're going to get errors).
AutoSponge,

Thanks for your comments.. Eventhough , I donot completely  interpret what you say , I am sure you know the stuff you are good at.. I am just beginning to set foot on these high-end routers so I have to do the basic homework of knowing about CISCO routers. I have 3 or 4 books here and I am going to spend sometime this weekend on going through this.

Thanks for hanging with me here.. This issue is not very high priority right now but we want to do this setup so that if we get new adtran routers next month , we would configure it here and donot want to go to a remote site to do the actual real time testing.. Not only does it saves lot of time but also I can get good knowledge ..

Sure you all can expect more questions in routers TA from me..

I am researching more on this issue aswell..  

Thanks all once again

SR
Any change to the status after setting the clocking to the Adtran side?
What does "show int serial 2/1:1" sho now? Does it still say "reset"?
Have the slip sec errors stopped on the controller?
Sorry , Lrmoore.. No change ..

I have changed the clock in Adtran and still cannot ping the 172.16.89.1  . From the laptop connected to the Adtran , I can go only as far as the WAN port of the Adtran..
From CISCO , I cannot go to 172.16.89.1 ..

Yes it still says reset for showing interface serial 2/1:1

Once again Lrmoore has proved is the best of the best..

Oh my goodness.  What a silly mistake ... I didnot plug the WAN cable properly at the back of the adtran. Everything was plugged in correctly but when I used  a cable tester to test the T1 cross-over, I guess I messed it up..

Also I think the main trick here was to change the clock inside the Adtran to source...

All righty, then...
Give yourself 3 whacks with a wet noodle for that one!

Glad you're up and running!

- 3 Cheers!

Now again one more question..  

Should I be changing the clock in the adtran to LINE if I take it to a remote site and plug a polycom unit to it or just keep it as source ..
Keep it just as is, assuming that it will be a leased line and the telco does not provide the clocking. That is a question that you must ask the telco when they establish the leased line for you..
Super.. I can now connect to all the sites (polycom) and remote desktop to all computersin all our counties..

Hopefully , tommorrow I will be going to the remote site and put this router there.. If I have any issues, I should hopefully tackle but will post another question (i guess I donot have to ...LOL)

Thanks for all your help , Lrmoore.. I guess you did hit the wall here but you should be confident that if you can do the same setup in 5 mins in ur lab , how come this one will not..

You are the Network King.

SR
>if you can do the same setup in 5 mins in ur lab , how come this one will not..
'cause I plugged the cables into the right holes?
I can only "see" so much in this type textual forum you know...

lrmoore,

Sorry if my silly mistake would have frustated you.

It should have been obvious for me to check on those cables but it never gave that clicking sound when I plugged into the WAN port. I guess i should tweak the cable little bit so that it gets fixed properly..
Nice lesson learnt..

Just glad you're working now!

Good lesson for both of us. I've got to remember to suggest checking, double-checking all the layer 1 connections before changing any configuration..
