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
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
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.
