Advice on how to setup WIC-1DSU-T1

Discussion in 'Cisco' started by Adrian Martinez, Nov 15, 2003.

  1. I have purchased two WIC-1DSU-T1s and installed them on two cisco
    2611s running IOS V12.0.

    How can I configure them to talk to each other and possibly simulate a
    frame-relay connection? If frame relay is not possible, then some
    other method.

  2. I just found out from a responder to one of my other posts that I need to
    start with a T1 Crossover cable. So let me get started on that layer 1
    issue first.

    Setting up a router to simulate a Frame-Relay switch is as easy as
    configuring a single global command, and 2 serial interfaces. The
    interface configurations should be identical, give or take 1 or 2
    commands. Below is a command line
    breakdown of a SINGLE one of these Frame-Relay Switching interfaces

    frame-relay switching <-- enables FR switching on the
    interface Serial0
    no ip address <-- no IP needed since no pvc is
    encapsulation frame-relay
    clock rate <A> <-- needed only in back-to-back
    frame-relay lmi-type <B>
    frame-relay intf-type dce <-- * logical DCE causes int to
    send LMI
    frame-relay route <X> interface <Y> <Z> <-- pvc switching command


    A = clock rate of line (e.g. 2000000)
    B = lmi type you wish to use (e.g. cisco)
    X = local dlci # of pvc connected to port S0 (e.g. 102)
    Y = interface remote dlci will terminate to (e.g. Serial1)
    Z = outgoing dlci # - dlci # of pvc connected to interface Y (e.g. 201)

    * - A logical frame-relay dce interface will PROVIDE, not RESPOND to LMI,
    so if the telco is providing LMI, you will NOT want to have this command


    Detailed Point-to-Point Frame Realy Switch Example

    frame-relay switching
    interface Serial0
    no ip address
    encapsulation frame-relay
    clockrate 2000000
    frame-relay lmi-type cisco
    frame-relay intf-type dce
    frame-relay route 102 interface Serial1 201
    interface Serial1
    no ip address
    encapsulation frame-relay
    clockrate 2000000
    frame-relay lmi-type ansi
    frame-relay intf-type dce
    frame-relay route 201 interface Serial0 102

    If you are studying for a test you might want to dedicate one router as a
    frame switch and add two more routers that way you can get creative with
    routing protocols.

    Hope this helps.

  4. I brought the tools and created my own T1 Crossover Cable and then used
    instructions provided by "username" and the two 2611's are working perfect.

    Hello, I am pretty new at cisco. I was trying to configure my 2 2600 routers with t1 wics but couldnt get it to work. Is the configuration below the configuration for both routers? or is it different for each one?

    I was trying this command line but it kept on giving me this error:

    CCNA1(config)#int s0/0
    CCNA1(config-if)#no ip address
    CCNA1(config-if)#encapsulation frame-relay
    CCNA1(config-if)#clockrate 2000000
    CCNA1(config-if)#frame-relay lmi-type cisco
    CCNA1(config-if)#frame-relay intf-type dce
    CCNA1(config-if)#frame-relay route 102 interface Serial1 201
    % Invalid input detected at '^' marker.

    based from the configuration that was given by "username", i assued that Serial0 refered to my interface s0/0 and Serial1 referred to another serial interface on the same router. But the problem is that i only have 1 serial interface with my wic. the other wic is installed on another router.

    Please help! thanks in advance!
