My support team is trying to troubleshoot a strange issue that we are having with our two switches. We just replaced an old switch with a new Catalyst 2960 which then is connected to a 2950 in another part of our building. When we connect the two switches together, there is no connectivity at all. No lights, no active interfaces. I suspect that it is something with the new 2960. I have tried different ports, I have tried different cables, but it still acts like there is nothing plugged in!
We did plug the cable into the uplink port on the 2960 and the interface finally came up, however then on the 2950 we are getting mismatch duplex message.
We have had a few people look at this and none of us have ever seen this.... Any suggestions????
Thank you in advance.
