Hi everyone!
I need some advice. I am planning to connect the following switches by multi-mode optical fiber: IE-3010-16S-8PC (with GLC-FE-100FX= into the 16 x SFP 100Mbps ports) and WS-C2960CX-8PC-L (GLC-SX-MMD into de 1Gbps uplinks). The port velocity does not match in both switches. So I am wondering if the 1Gbps uplink port could negociate the velocity and eventually set up the connection.
Kind regards
Miguel

No - sorry that won't work.
The gigabit SFPs you have in the 2960 operate only at that fixed 1 Gbps speed. There is no speed negotiation capability in optical transceivers since the optics operate at a fixed speed.
You could replace the GLC-SX-MMD gigabit SFPs in the 2960 switches with 100 Mbps one and that would work fine. The part number needed would be:
GLC-GE-100FX |
100BASE-FX SFP for Gigabit Ethernet SFP Ports |
