I have 3750-X-24T stack with 2 module C3KX-NM-10GT installed in each one , my software code is 15.0.2(SE8) , only single 10G port is working.
does anybody faced this problem before , I am sure that I am on the proper code as per cisco recommendation , I have checked the connectors and those other stuffs.
Can you switch the cable and than the optics between the working one and the non-working one and test? This test will let you know if both the cable and the optics are good.
Hi Reza ,
thanks for your response , actually I did this test yesterday and unfortunately there was no positive results , I am using cables (Cat-6a) .
to be specific
I did the following tests
- endpoint 1 is running 10G and connected to port Te1/1/1 on the 3750-X and working , I tried to move the cable from Te1/1/1 to another port (Te1/1/2) and it didn't worked.
there are no configuration under ports , the speed is 10G ( I didn't changed it)
Do you have the same issue if you connect the 10Gig ports between the switches?
So, what if you connect sw1 port te1/1/1 to sw2 port 1/1/1, if good take the same cable and connect sw1 port 1/1/2 to sw2 port 1/1/2.
I tried this too , they are running is stack , I managed to remove the stack cables and test this scenario too to make sure both ports will run in 10G speed
