I am new to Cisco switches world.
I have one Catalyst 2960 switch with 4 Gigabit ports.
Using gigabit ports with GBIC (1310nm), this cisco switch was not able to connect to D-link or 3Com switches with the same gbic model and port type.
But I could make 2 d-link switches talk to each other using the same optical fiber structure and port type. And the same with 2 3com switches.
Is there any kind of incompatibility between catalyst 2960 switches and other ones? Or is it misconfigurated?
