We have several buildings on campus. In our main building we have a core switch which is a Cisco 3560X (with a C3KX-NM-1G module installed) and a Cisco SR2024, among other switches. In another building I have a LinkSys SRW2008. These two buildings were connected via fiber between the LinkSys SRW2008 and the Cisco SR2024 switch using a Mini-GBIC MGBSX1 connector on each end.
Over the weekend, the SR2024 died (no power). I'd like to move the fiber connection in the main building to one of the C3KX-NM-1G ports in the 3560X. At first I just moved it, but the port immediately went to error. I removed the fiber from the Mini-GBIC and did a
no shut. That has removed the error. I then connected the fiber back, but the port still shows no connection.
Is there something I need to do to get the port to recognize the link? I thought it would do so automatically, but in my very limited understanding of the Cisco IOS, I was obviously wrong.
Can someone help me configure this link so I can get that part of our network back up?
