I am having issues bringing up SFP uplinks on Ce 500. they Uplink have GLC-FE-100FX Gbics. I have checked the SX multi mode cables on other switches, and tested them with a fiber light, they work fine. My only conclusion is that the GLC-FE-100FX are faulty, but i have tested all 15 of them, its highly unlikely. I configured the SFP ports as smartport Switch but that didnt help either, The CE500 data sheet says that the GLC-FE-100FX are supported, maybe i am missing some configuration on the ce 500 , i dont know, any help will be appreciated
PS... the ethernet ports, uplinks come up fine .
