I want to link a cisco 2960 with cisco 2950 from optical fiber.
my 2950 configuration is good on his Gb0/2, we test the link with an another switch 2950.
but i don't have the configuration for the 2960, i try to configure it with the same parameters like the 2nd cisco 2950(who is good), but i haven't a link with 2950
on this one i've got an rj and a sfp module.
When i link rj leds are green when i connect fibers on sfp module nothing (i disconnected rj45)
can you help me please
