    I've done my ccna intro and i'm halfway through the icnd book and thought it was a good time to try and get my home lab all hooked up.

    Just now i have:

    2501 Router
    2503 Router
    2504 Router

    connected to each other via some very clever cables that have a DCE connector on one end and a DTE connector on the other (DB60 Crossover cables i believe they're called).

    My plan was to link them similarly to so many of the examples in the ciscopress books i'm reading (all routers linked to each other).

    Here is the ip address scheme i used.

    2501 Router (Hostname: Charlie)
    Serial 0 - 192.168.0.246/30 (James)
    Serial 1 - 192.168.0.253/30 (Matt)

    2503 Router (Hostname: Matt)
    Serial 0 - 192.168.0.254/30 (Charlie)
    Serial 1 - 192.168.0.249/30 (James)

    2504 Router (Hostname: James)
    Serial 0 - 192.168.0.250/30 (Matt)
    Serial 1 - 192.168.0.245/30 (Charlie)

    And here are the config files from each router:

    The Problem

    James reports both serial links as up & up, can ping matt, but not charlie.

    Matt reports its link to james as up & up but reports its link to charlie as up & down. Can ping james, but not charlie.

    Charlie reports both links as up & down and can't ping anyone.


    Can anyone tell my why charlie is behaving this way, or what i've done wrong? Much appreciated 8)


    EDIT: Forgot to mention that matt and james have each other in their cdp neighbor list, but neither has charlie in their list, and charlie has no one in his.

    Have you tried to reverse the clocking statements on Charlie?

    Cheers for the reply. Just tried that there - serial 0 rejects the command, saying it applies to DCE interfaces only.

    And i've checked the cable - the DCE end is definitely in charlie serial 1.

    Anything else?

    try setting your clock rates to 64000. I know you can have the clock rate set up to:

    CAC-Riverside-3845-1(config-if)#clock rate ?
    :h:00-4000000> Choose clockrate from list above

    but most of the labs I have seen have usually used 64000 as the clock rate.

    Once you do this do a shut no shut and see what you get. If it is still down can you paste the following output:

    Sh ip int bri
    Sh interface (s0 or s1)

    Also try swapping the known good cable to the interface that isn't coming up. I wonder if it is your back to back serial cable?

    Clock Rate 64000 worked great. Some clock rates aren't available on certain IOS versions I found out. 125000 was available on one IOS but not on another. On the other 128000 was available. I don't know. BUT 64000 was on all of the IOS that I tried and it worked fine and will be fine for lab use.

    From Charlie:

    Device ID Local Intrfce Holdtme Capability Platform Port ID
    MATT Ser 0 135 R 2620 Ser 1/1
    JAMES Ser 1 144 R 2511 Ser 1

    From James:

    Device ID Local Intrfce Holdtme Capability Platform Port ID
    MATT Ser 0 156 R 2620 Ser 1/3
    CHARLIE Ser 1 130 R 2509 Ser 1

    From Matt:

    JAMES Ser 1/3 168 R 2511 Ser 0
    CHARLIE Ser 1/1 159 R 2509 Ser 0


    By the way..whats up with your enable password: Cockarm? You strangl'en some chickens? :eek:

    Thanks so much for your help!

    When you mentioned the clocking before i had a go at changing them all to 9600, just to see if that was the problem, but i got the same problem. Just tried 64000 and the same happened.

    And i've just tried using all 3 cables in the link that does work (matt <-> james) and all three report up and up and ping correctly.

    I'll post the outputs you requested later on, but it's looking like charlie is 'busted' (the irony that i named my 3 routers after members in the band busted...)


    Thanks for your help again!

    Hi Surfer Rosa,

    I'm sort of new at this as well, so I could be totally wrong.

    But your ip addresses look a little wierd. Think that could be the problem ?

    192.168 is a class-C address. But the way you set them up are like network i.ps of a class B subnet.

    Try 192.168 dot 1 instead of dot zero and see what happens.

    Another thing you could try is do a sh ver on the malfunctioning Router to see if the config register is right.

    Another thing you can try is to check your cabling. I've found out the hard way that when you plug the DTE end into a port meant for a DCE, then the Router usually doesn't work right. You can check this physically, or if your cables aren't labelled, you can check it on the sh controllers command.

    That's all I can think of right now. Let us know how you get on.

    Cheers.

    It shouldn't be the config register since he is booting up his IOS fine. He could try upgrading his IOS or checking to see if they are the same versions as the routers that are working...I suppose.

    Honestly I wonder if the port is bad, however the SH INT shows an UP/DOWN status which usually would indicate you have a layer 2 issue. The ecapsulation should default to HDLC so that shouldn't be the problem. The only other other issue could be the clocking...that I can see. He tested the cables on the link that is working...

    Good thoughts though. He could try turning on Debugging to see at what point the link is failing...

    My bad with the i.p thing.

    Perhaps Surfer can post readouts from show controllers on all three routers to confirm that the clocking and the connections are up to scratch ?

    Like you say, the port probably isn't the problem. But just for kicks, he might try swopping the connector over to a different port or if he's handy with a screwdriver, remove the module entirely and swop it with a module on one of the good routers.

    I'm probably talking out of my ass at this point. I'll wrack my brains later on and see what else I can come up with.

    Cheers for the replys guys. Its good to get some brainstorming on the go.

    I thought the subnets were fine to be honest but i decided to go with a more 'classful' ip address structure just for testings sake.

    Used class C network addresses with the default subnet mask (255.255.255.0 - /24).

    Charlie S0 - 192.168.1.1
    James S1 - 192.168.1.254

    James S0 - 192.168.2.1
    Matt S1 - 192.168.2.254

    Matt S0 - 192.168.3.1
    Charlie S1 - 192.168.3.254

    And again it's the same problem... matt and james linking up fine, with nobody able to reach charlie.

    In terms of the router IOS, charlie and matt are 12.3, james is 12.1 and seeing as charlie is the problem one, i don't think it's the IOS. I backed up the 12.3 IOS image though and was going to transfer it to james, but there isn't enough flash on it :cry:

    As you can see HDLC is being used on charlie and i checked the other 2 - its the same situation.

    I'll post any interesting readouts later. Please post any useful debugging commands as this is my first time using routers so i'm not exactly a seasoned pro :biggrin

    And yeah - i am actually fairly handy with a screwdriver - that idea is definitely worth a go 8)

    Ok - here's the output of show controllers on all 3 routers. I occured to me that maybe there is a bad port in each of james and matt, and that charlie is totally fine. I'll change the link from James S0 - Matt S1 to James S1 - Matt S0 to check that. Anyway...

    The serial interfaces on his routers are fixed, at least so I am aware. I could always be wrong...I haven't cracked open a 2500 series router in a long time to see if you can remove the ports from the system board.

    Hi Surfer,

    Sorry, I've never worked on a 2500 series before. Is it true the ports are fixed like NetEyeBall says ?

    Anyway if you're still checking for a physical problem, then one way I would do this is to remove one of the good routers from your pod and just test connectivity exclusively between the remaining good one and the bad one. It just makes things more convenient is all. I'll suggest you use one single cable between the two routers, moving it back and forth, from port to port. And while you're doing that make sure you're consoled into the bad router. Every time you move the cable, you do show controllers to check whether the router can tell the difference between being connected and not being connected. If it can tell the difference, then it's probably not a physical problem.

    The only other thing I can suggest is to try one of the routing protocols.I don't know if rip is up to the job, but whichever one you chose, maybe the sh and debug commands can tell you something.

    The show controllers output you posted are a bit tough to figure out. I couldn't tell where one interface began and where the other one left off. When I do the same command on one of my routers, it looks something like this:

    sh controllers

    Well, i don't even know which router is the good one or the bad one now... just did a test between the two routers that i thought were working (james and matt) - here are the results:

    Code:
    Clocking	Receiving	Works?
    
    James Se 0	Matt  Se 0	NO
    James Se 0	Matt  Se 1	NO
    James Se 1	Matt  Se 0	NO
    James Se 1	Matt  Se 1	NO
    Matt  Se 0	James Se 0	YES
    Matt  Se 0	James Se 1	NO
    Matt  Se 1	James Se 0	YES
    Matt  Se 1	James Se 1	NO
    By receiving i mean the device is receiving the clocking.

    I've also been getting alot of errors like this:

    when the devices aren't working. I might research that for a bit, then compare the differences of show ip interface serial 0 / serial 1 on james, to see why serial 0 can be 'clocked' but not serial 1.

    Thanks :(

    Well i'm pretty stumped for the time being. I've done what you said though by making things alot simpler.

    I'm just using 2 routers, and i'm using 1 link that doesn't work to see if i can diagnose the problem. Here are the configs i'm using for the routers:

    Code:
    matt # sh ru
    Building configuration...
    
    Current configuration : 632 bytes
    !
    version 12.3
    service timestamps debug datetime msec
    service timestamps log datetime msec
    no service password-encryption
    !
    hostname matt
    !
    boot-start-marker
    boot-end-marker
    !
    enable password cisco
    !
    no aaa new-model
    ip subnet-zero
    !
    prompt %h%s%p%s
    !
    !
    !
    interface Ethernet0
     no ip address
     shutdown
    !
    interface Serial0
     ip address 192.168.0.249 255.255.255.252
     clockrate 64000
    !
    interface Serial1
     no ip address
     shutdown
    !
    interface BRI0
     no ip address
     shutdown
    !
    no ip http server
    ip classless
    !
    !
    !
    line con 0
    line aux 0
    line vty 0 4
     login
    !
    !
    end
    
    james # sh ru
    Building configuration...
    
    Current configuration:
    !
    version 12.1
    service timestamps debug uptime
    service timestamps log uptime
    no service password-encryption
    !
    hostname james
    !
    enable password cisco
    !
    !
    !
    !
    !
    ip subnet-zero
    !
    prompt %h%s%p%s
    !
    !
    !
    interface Serial0
     no ip address
     shutdown
     no fair-queue
    !
    interface Serial1
     ip address 192.168.0.250 255.255.255.252
    !
    interface TokenRing0
     no ip address
     shutdown
    !
    interface BRI0
     no ip address
     shutdown
    !
    ip classless
    no ip http server
    !
    !
    line con 0
     transport input none
     line aux 0
    line vty 0 4
     login
    !
    end
    So that's matt se0 to james se1.

    The output of show interfaces on each on is:

    Code:
    [b]matt # sh int se 0[/b]
    Serial0 is up, line protocol is down 
      Hardware is HD64570
      Description: link to charlie

    The '97 input errors' sounds interesting...

    and

    Code:
    james # sh int se 1
    Serial1 is up, line protocol is up 
      Hardware is HD64570

    If anyone can shine a small amount of light onto this it'd be greatly appreciated. But, if in your opinion these routers are fudged, then also let me know 8)

    Thanks...


    EDIT: Just noticed that when i switch off 'james', matt will notice and change se 0 to down and down - so there must be some sort of comunication going on!

    EDIT: Sorry, I posted this before I saw your last post. Maybe this post no longer applies so just ignore it. Damn ! That diagram doesn't look anything like the way I drew it either !
    -------------------------------------------------------------------------------------------------------------------------
    I'm only guessing here, but if you're unable to clock serial 1 then it's probably because that port is connected to the dte end of the cable. You can't clock it.

    When you connect the dte end of any cable to any serial port, the interface that that port belongs to immediately becomes a dte port. When you swop the cable around and plug in the dce end, then that port immediately becomes a dce. You don't clock dte interfaces, only dce interfaces.

    Sometimes the connectors on your cables are labeled DTE on one end and DCE on the other. In such cases it's easy to see what end you are plugging in. Some cables are however unlabelled and the only way to find out what end of the cable you're plugging in is to check sh controllers.

    Maybe you already know this, in which case just ignore me.

    But if you don't, then I suggest you sort out your cabling first and foremost.

    Try the following topology:

    Router1 Router 2 Router 3
    O.............................. O .................................O
    S0 S0 S1 S0
    DTE DCE DTE DCE

    Clock all the dce interfaces at 64000 and then test.

    And while you're at it, check the bandwidth on all your serial interfaces and make sure they're up to scratch. I think the default is 1544 kbit which works okay for me.

    Let us know how it turns out.

    Just ignore the last post, since it now seems that this is more of a datalink layer problem.

    The 97 errors thing, I don't know what the heck that means !

    I'm clutching at straws here, but maybe you can try debugging with one of the protocols, like rip, for example.

    Boy this is a toughie !

    Yeah! And to think i downloaded boson netsim and made a perfect replica of my initial network without any errors in about 10 minutes...

    To be honest i'd feel a bit cocky configuring rip when the basic configuration isn't even working! But i'll give it a go and see what i can come up with.

    Cheers.

    Configuring a dynamic routing protocol won't fix your issue. Sorry to say. You should have connectivity since they are all directly connected. Directly connected interfaces can talk to each other since they are aware that they exist without need of a routing protocol.

    But you can configure rip if you want...:)
