Hello together :)
So I will try to explain my problem with my bad English and hope that somebody can help me with that.
I just bought a Meraki MX250 for our company to replace an older Firewall and I confugured it exactly like the old Firewall just with another public IP. So far so good.
But when I try to connect the Meraki MX250 over the WAN port to the Cisco 3560 switch, nothing happens. I don't get any link and the port on the 3560 says that nothing is connected.
I have resetted the port already, also the Firewall. But still nothing.
When I connect the Firewall to another office Switch, it is working without any issues.
The port on the 3560 is also not broken or something because when I connect something else on it, I got a link too.
So both connections are working with different devices. I can't just get it why I don't get any link when I connect the firewall to the 3560 switch.
And yes, I need this switch, because it is the switch between our internet and the company network.
So far
Daniel

media type is 10/100BaseTX
I on the understanding the Mx's use by default 1GB interconnects for its wan/internet ports so it is possible it cannot negotiate with the 3560 at 100mb.

Can you post the configuration of the port you connecting MX250

Oh yes, sorry forgot it:
