Hello, I want to ask a very basic question, but it has me with doubts. I am entering the Meraki world. I need to install a 10Gb SFP + on a MS425-16 Switch, which is connected to another switch NOT Meraki, but with a 1Gb SFP. Will the Meraki SFP + negotiate at 1Gb against the other switch without problems? Later it is planned to upgrade all switches to 10Gb.
@JorgeQ12 : SFP and SFP+ modules look exactly the same. And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa. However, the connection won’t work as you expect it to. Or, worse even, it won’t work at all. If you plug an SFP device into an SFP+ port, the speed will be locked at 1 Gbps. Plugging an SFP+ module into an SFP port delivers no results at all, as the 10G transceiver can never auto-negotiate to 1Gbps.
I understand. But at the level of interface negotiation in each switch, being the MS switch the one with the 10Gb SFP +, and the other switch with its 1Gb SFP, the link between them would not be negotiated at the lowest speed, which would be at 1Gb?
