What this Debug output is trying to say?

Since I am short of cash, so I have not bought myself a new NM-4A/S.
The settings that I have on R4 are this:
conf t
hostname R4
int s1/1
ip add 192.168.2.226 255.255.255.252
no shut
on R1 is similar; but the ip is 192.168.2.225/30 and the clock rate is 64000. And it has WIC-1T.

So I executed the command debug serial interface on my 2620 router(R4) that has the NM-4A/S.
Here is the output:

Don't really know what all that means.

However, tomorrow I can jump on my router which has the same module you have and show you my output if that will help to compare...

Of course, unless someone else can chime in....

That would help a lot, man.

You most likely have an HDLC configuration problem.

post the show int and show controllers for the respective serial interfaces from both routers, along with the configurations of those interfaces

His issue is that it's possible he has a bad module. We had an extremely long thread awhile back going over HDLC and PPP configs, and no matter what we tried couldn't get a link to stay up...

Sounds like one of those 'ebay shotty module' things. I even know that some sellers on ebay sell shotty modules, and I'll probably still buy it from there.

We should start a thread identifing bad sellers.

That is a good idea.
I still remember the seller name. And he has a 99.8% positive feedback.

I think it is my fault for not checking it when I bought. Well, at the time I bought it I was in chapter 2 (CCENT). So I had no idea how to test the module.

Anyways is the command debug serial interface the proper command for checking the faulty module?

@Forsaken_Ga
Give me like 15minutes and I will post those here.

I'd be all for this. My lab (like most others here I'm sure) will probably be a work in progress for the foreseeable future.

This is a fantastic idea! And it should be PINNED!!!!

Now look, some sellers don't even know they have shotty stuff, so we can all vote and feel things out if we want to list them, but for those that may know and don't care, we put them on the list!!

Let's do this!!

Someone needs to start that thread and willing to edit the thread if necessary.

Alright here is the show int and the sho controllers for both routers

His issue is that it's possible he has a bad module. We had an extremely long thread awhile back going over HDLC and PPP configs, and no matter what we tried couldn't get a link to stay up...

It's possible, sure, but you need to boil it down to the point where you can prove it's the hardware. The easiest way to do that is swap the questionable modules out with known good ones. If those don't come up, then you've got a configuration issue. If they do, then you've got a hardware issue.

I'm guessing he doesn't have that in this case, and the original question was what was the debug output trying to say, and what it's basically saying is that he's got an HDLC problem. Whether that's because of hardware or configuration, remains to be seen yet.

thehourman, clear the counters on those interfaces, and give it a few minutes and then check the show interface again, I'm curious to see if the carrier transitions increase again

thehourman

Do you want me to clear the counters on both interfaces then run the same debug command?

I will post the output tomorrow morning, because it is really late right now.

Unfortunately, I don't have any NM module, so I can't do the swapping; however, I did try that NM-4A/S on a different router and it did the same problem which is the up down.

APA

The fact that DCD, DTR etc are restarting consistently on the NM-4AS indicates that you definitely have a L1 issue...

1) Change the cables....

2) If the cables don't resolve the issue then replace the faulty modules...

It looks like a bad module to me.

I think he's talking about his posted working sample output.

yeah I was talking about MY OUTPUT...

Come on APA! LOL!!!

haha my bad.....

I'm operating on 2 hours sleep because of multiple third-party failures....... sorry!!!

I blame the small size of my mobile phone screen, thus not a clear view...

The dude who sold me that NM-4A/S, I have not gotten a reply from him after I replied to his last email. I think he is wasting the remaining days that I have. I only have 4 more days left to return the module back to him and get a working one.

@notgoing2fail,
Thanks for posting your output. At least now I know what is a working output looks like.

Also, I have an off-topic question. Is SDM really important on ICND1 and ICND2?
I can't use the SDM on my 2620 routers. When I typed in the ip add of my 2620 it says the router is not supported.
I have not practice anything about SDM. The only knowledge that I have about SDM is I saw some pictures in the book and read some stuff and that's about it.

It is on the blueprint so yes, it is important. You need to know how to use it. It isn't particularly difficult to use and if you know how to use the CLI then it will be easy. The issue is that you don't want to waste time in the exam working it out.

SDM isn't supported on a plain 2600.

Download the SDM demo from the Cisco site (Search for it) or try to get it running in dynamips.

It looks like for ICND1 you have to know how to use SDM for NAT, DHCP and DNS and for ICND2 "to set basic parameters" and for ACL's. It doesn't really sound like a lot. I'm going to sit down and try getting it going in GNS3 this weekend since it's the one thing I didn't get to play with in class (we tried all semester but nobody could get it going) and I don't have a capable router at home.

And unfortunately you need at least a 2600XM to use SDM. All of the supported routers are listed in this doc for anyone whos interested.

As the datasheet says, any 2600XM will do. You don't need the 2620XM model since that just gives you a faster CPU than the 2610XM.

I actually meant 2600XM. Thanks for catching that.

Ahh okay.

The minefield is with the 1700s as some of those came in odd configurations that aren't well supported by IOS or SDM like the 1710 or 1720. They're usually really cheap on eBay as well...

I downloaded the demo and installed sdm 2.5.
I installed sdm on my

drive and extracted the data file in C: drive. Then I typed in 127.0.0.1 and it did not work. Should I move the data folder in

drive instead?

thehourman

OK, so I reinstalled the sdm 232 and installed it in C drive. And I have the data folder under C drive as well. Now I could not make it to work. When I put the 127.0.0.1 address, and clicked launch. IE7 opened and I can see the Cisco SDM, but thats about it. It says that I can close that windows because it will open another window for sdm. But the 2nd window never shows up. BTW, ActiveX is enabled, and the pop up is turn off.

Welcome to SDM hell, whether it's demo, simulated or real, there's only one thing that's guaranteed, you'll be pulling out your hair...

Wait till you play with it on a real device, it's not any easier....

thehourman

Now, I am getting really mad with this application.
If there will be a lot of question about SDM in the exam, then I will be damned.
I don't know what else I need to do to make it to work as a demo. I have tried to use Chrome, Firefox and IE, but none of them work.
