I am trying to connect 2 3560's via the SFP ports and I am only getting link light on one end and only one switch shows connected with an active trunk. The other switch sees the module but will not recognize the trunk and never does show connected or link.
The SFP's that I have tried are GLC-SX-MM and SFP-GE-S. The distance between the buildings is less that 500ft.
I am on 850-nm Fiber between buildings and it is currently working with a 6509 and a 4006. If I feed out of a gbic on the 6509, I get the same thing when attaching to the 3560.
Any help would be greatly appreciated,
