Interface problem

I have a Cisco 2621 series router with one WIC slot having two smart serial ports, The problem is my leased line works fine with one port but as soon as i connect to other port the line protocol turns down i am not able to find out where the problem is

I also tried to give a local loop from the modem in thr first port it shows looped but on the second port it doesnt even show looped

Now how do i find out where is the problem ,in the IOS or in the second port pls provide some solution

Re: Interface problem

Hi

(1)Are you switching the ports with the same link? Or you are installing a new link.

(2)What is the capacity of lease-line? A WIC-2T card support upto 8Mbps but on single port.At that point your other port will not work.

(3)Can u switch your existing lease line to non-working port and see?

(4)If your lease line is say of 2Mbps and you are installing a new link of say 2Mbps, and the WIC is not responding properly, then you have a hardware prob.

Pls give the required inputs.

Re: Interface problem

hi thanks

i am installing a new 2 Mbps link and my previous link which is on the other port (which is working is also 2 Mbps)

Yes i tried switching the existing lease line on the non working port but it did not work

i guess i have some problem with the hardware , i tried debug interface serial but i didnt get any response

thanks

Re: Interface problem

Have you checked the controllers status sh controllers, this will give you some insight as to the problem, also I am not sure if this will have anythning to do with your problem, but try and add a clock rate ex conf t

int "controller" clockrate 64000, after this look at the controllers status by sh ip int br "controller int", and sh controllers. Hope this helps

Re: Interface problem

If you are using one WIC-2T, i.e. one module w/ 2 serial interfaces and you ensure the configuration is correct. You also carried the swap test (include links and cables) then I believe it should be the hardware problem. Try to obtain another module from your vendor and test again. Or bring another router w/ module to carry the test.

Hope this helps.
