Flapping Port

[E1or0]

Hi guys, I'm trying to set up a Back-to-Back lab but I'm having issues with my Serial 4A/S interface from one of the two Routers I'm using, one is a 2600 series and a 2500, the serial interface from the 2600 series that I'm using keeps dropping and coming back up - any suggestions why this is happening? :(

I just tested this with two 2600 series Routers and the same thing is happening :rolleyes:

[lammle]

Do you have another cable you can try?
Todd

[E1or0]

Thanks Todd for replaying, I'm driving my self crazy here, yeah I tried a new cable and still doing the same thing, I'm updating the ios image it might be corrupted, will update you in a couple of mins

[E1or0]

Updated ios images from both Routers 2600 series and still this serial ports flapping, I'm getting this at boot from both Routers Smart Init is enabled

[bs_kwaj]

Can you post the output of 'show controller' for the two interfaces. Maybe there's some sort of mismatch in what each is expecting. (I'm a newbie drawing at straws!)

Maybe one of your serial ports has just gone wonky. ;)

Nothing is UNKNOWN in your previous output:

[lammle]

just the first three lines of the show controllers output, also provide the show interface output of each interface, see if one serial interface is in loopback mode. It does sound like a bad interface

[E1or0]

Ok this is the output from the Router acting as the DCE Router#show controllers serial 1/1

Channel mode is synchronous serial

and here goes the one acting as the DTE

CD2430 Slot 1, Port 3, Controller 0, Channel 3, Revision 19
Channel mode is synchronous serial

[E1or0]

no none of them are in loopback mode Todd - I have spent all day troubleshooting this won't give up :D

[lammle]

The outputs look fine (other than the up/down), so you can only have a bad interface or bad cable. I don't know of third problem that can be causing this.
Todd Lammle

[E1or0]

Lets suppose I have a bad interface, this is a 4A/S Serial wic card, can the whole wic card be bad?

can this be also a reason? I don't think so cause this was already showing up before installing this wic card

show version from the DTE Router

and from the DCE Router

Hello,
could you upgrade the DTE 2610 to IOS c2600-i-mz.123-19a.bin?

I'm always skeptical when you can't download a IOS file from the Cisco Feature Navigator. You can't download Version 19 but you can download version 19a.

By the way, you can check the cable with the 2500 router (I presume it has two serial interfaces). Don't forget to make sure that you plugin the cable correct and not upside down.
Bye, Tore

[E1or0]

the serial cables are connected correctly now I just tested with the 2500 Router and are this 2600 the ones dropping its interfaces unbelievable

[E1or0]

I don't have a CCO Account with cisco to download further images :(

[crissa]

the serial cables are connected correctly now I just tested with the 2500 Router and are this 2600 the ones dropping its interfaces unbelievable

Hello,
so the 2610 with the IOS c2600-i-mz.123-19.bin is the one with the problem?

If you can't upgrade the IOS: Could you test the NM-4A/S module with the other 2610 and the 2500 router, please?
Bye, Tore

[E1or0]

the ios was recently updated i had it with a different one "c2600-is-mz.121-5.T9" will changed the Serial 4A/S to the other 2600 to see what happens will update you crissa in a couple of mins

[E1or0]

Ok I changed the Serial 4A/S Wic Card to the other 2600 set up a Back-to-Back connection with the 2500 Series and still dropping link, tested a 2nd Wic Card I have here and still doing the same thing, I don't think the Wic Cards went bad at the same time and neither the Routers must be something else

Router needs an upgrade of CR dude...:p
Have some CR and everything will be fine then.

[E1or0]

Pramod.purohit Thanks for helping out but could you be more specific, I'm currently working on my CCENT I'm not that advance YET:D, CR What is that ? :confused:

[crissa]

Hello,
even if you updated it an hour ago: If Cisco says that you can't download it anymore or that they added security advisories I wouldn't use it anymore. I did a downgrade on my 3640 routers a few weeks ago as the IOS I used had security advisories.

Could you find a way to check the cables without the NM-4A/S that is in question? Do you use crossover cables (with only a plug at each end) or did you plug a female and male cable togethter (with two DB-15 connectors in the middle)? I use cable clips to secure the DB-15 connections.

One of the problems of troubleshooting is to make sure that something is in order so you can use it for testing. As long as you are not sure that the cable is working without problems you can't use it for further tests. And if every cable you try to use makes problems you must question the ports or the config you use for testing!
Bye, Tore

[E1or0]

http://www.smartech-solutions.com/images/SerialCable.jpgThis is the type of cable I'm using crissa, I remember in a different lab I did long time ago i did used the one with two DB-15 connectors in the middle, whats the different of using this two types of cables? the ones I'm using are like the one in the picture one end is for a DCE Equipment and the other for a DTE

Hello,
the difference? Better handling as the crossover cable is shorter and you don't have the DB-15 connection that could fail.
Bye, Tore

[E1or0]

So you saying this cable I'm using DCE/DTE DB60 Crossover could be bad? I have tried a whole bunch of them and still stuck with the same problem

[crissa]

Hello,
so maybe the problem is the interface or the config. I don't think that all your cables went bad on the same day. ;-)

[E1or0]

Ok will try to install this Serial 4A/S into a 3rd 2620 Router to see what happens will update you guys in a couple of mins

[E1or0]

Ok I installed the Serial 4A/S Wic Card to a third 2620 I have here and the link still dropping, either the Wic Cards went bad, or this DB60 DCE/DTE Crossover cables are no good, will try with the one you mentioned earlier crissa with the DB-15 connector to see if are my cables that are no good or the Wic Card, will continue to update you guys, thank you for all of your support

Hello,
you wrote you also own a 2500 router. Maybe you could check the cables with this router (my 2500 routers have two serial ports). The point is to test your cables and your configs without the NM-4A/S module that is in question!

jst kidding....

I hope yr problem is solved now.

[E1or0]

Crissa that would be good but I only have a single 2500, would I be able to test this cables using both Serial Interfaces that this single Router have? Or I defently would need two 2500's ?

Very good post bs_kwaj about the counterfeit Wic cards will check mines as soon as I get a chance.

Hello,
give it a try! If the 2500 has the only two serial interfaces you can trust it is the only solution to check the cabels.

I didn't tried it myself so far, but I could as I also own 2500 routers.
Bye, Tore

[E1or0]

Crissa I think we getting closer to find the issue here, I tried with the 2500 connecting both Serial interfaces and both interfaces were dropping the link, Now I feel much better seems like a DCE/DTE Serial Cable issue, will wait until Monday to get a DB-15 to DB-60 cable from the office to try again, Hopefully are not my Wic Cards the ones that are bad lets pray are the cables only LOL !!! Thanks once again Crissa :p

And could you post the config you used on the 2500 router for your test, please?

I have such a nice lab and I'm about to dump all this stuff out the door, sorry guys but I'm stressed out here, I just got the DB15 to DB60 cable to try with and still having the ports issue where they go up/down unbelievable, here i posted the router info the one I'm using now to see if any of you guys see something suspicious, Now this below is something that I can't understand why is happening does any of you have any idea?

Hello,
so back to the assumption that the NM-4A/S module is broken.
Could you try to use two of the S0/x ports on this router?

I don't understand your problem with the booting message. Could you explain what bothers you?
Bye, Tore

[E1or0]

crissa the booting messege does not bother me at all, is just that I don't know if that is affecting my ports some how just wondering now I have three 2600 series routers and a 2500 only one of the 2600 have the smart serial wic card with a dsu/csu wic card I could also use the T1 dsu/csu with a crossover RJ48 cable but again is the only one with this wic cards, the other two only have the NM-4A/S wics, this is why I need this NM-4A/S working.

What I don't understand is that this routers are form 3 different vendors I can believe this wic cards came bad from this 3 different places, could it be a corrupted image?

Hello,
could you do a "show version" and post the outcome, please? Maybe it is a good idea to give each router a hostname and to add the prompt (with the hostname) to the outcome.

I already wrote something about one of the IOS version. Maybe this (third) router also has an outdated IOS. (The processor id is new to me ... ;-)

By the way, I tried to get a boot message like the one you posted. But my four 2500 routers and my four 3640 routers didn't show one. I know this boot message, I already saw one. But where (at home or at work) and with which model? I can't remember!
Bye, Tore

A buddy of mine will bring one of his NM-4A/S Serial Wic Card next week to use it on my 2600 to check if is my cards the ones that went bad :(

anyway check the version and elt me know what you think

thank you again crissa

Hello,
could you try "c2600-ipbasek9-mz.124-23b.bin", please? It is only IP BASE but it should do the job.

I couldn't download the version you are using at the moment ...
Try <http://www.cisco.com/go/cfn/>.

You have three 26xx routers and two of them use IOS version that, hm, are a little bit interesting. Maybe you should change the IOS. :-)

By the way:
Maybe you could ask your buddy to bring the module and the router.
Just an idea! ;-)
Bye, Tore

I don't have a CCO account to download c2600-ipbasek9-mz.124-23b.bin, is there a command that I could use to debug the communication between this two ports DCE/DTE ???

and yes I'm waiting for this guy to come by and drop me his wic card and router to test them

Hello,
I can't help you about the CCO account.

But maybe you can do some "copy flash: tftp:" practise. As long as the router has enough DRAM and Flash you can use the IOS from another router (if they are the same type). You can check with <http://www.cisco.com/fo/cfn/> what are the memory requirements of an IOS.

a friend of mine will be coming with his 2600 to check my cards and router, it would be nice to put my routers in loopback mode just for testing purposes I'm guiding my self/learning from this site http://www.cisco.com/en/US/tech/tk713/tk628/technologies_tech_note09186a00800a754b.shtml now I have a back-to-back set up I don't use the CSU/DSU I don't know if this procedures are ok when using just the serial ports and not the csu/dsu ???

sorry, I'm not aware of a loopback test for a DB-60 connector.

Seems like everyone else gave up on me :( except Crissa, Well I have good news guys after all the troubleshooting and the time that I spent with this serial ports going up/down on me, I have found the solution.........two bad NM-4A/S Serial Wic Cards that were sold to me on ebay GRRRRRRRRRRRRRRRRRRRR :mad:, I decided to buy a new one and guess what guys? It WORK !!! Can't believe it. I will post close ups of the 2 Cards and the new one I just got, there is something on this boards that might help future buyers of this Serial Cards identify if it could be bad or not anyway just for you guys to take a look at.

I thank you all for your time and help, I really appreciated

[crissa]

Hello,
I'm sorry to read that, after all the testing, our assumption came true that the cards are the problem. If you only change the card (with the one from your friend) and all other things (like routers, IOS versions, configs and cables) are unchanged the solutions is easy => broken card.

As far as I know at work we only buy from Cisco. Or reuse equipment that comes back from a customer. If it doesn't work, get the next one. For me it is very uncommon to see broken cards or spend so much time for troubleshooting. My hope was all the time that the cards are OK and we missed to check for all problems that could occur.

Good luck with your next cards! :-)

So... See, I had run out of ideas. Glad to see I was right though in my initial analysis back up at post #30... Wonky WICs! ;)

I've had good luck buying used stuff from http://www.cablesandkits.com/cisco-network-equipment-c-50.html .

Glad you got it sorted out. :)
