Meraki MS350 to Brocade ICX6610

Hi guys,

I am having a weird issue. I have a Meraki switch that I am putting in a separate building to replace an older switch. It uses fiber to connect back to our Brocade Core Switch (ICX 6610). When I connect the fiber up to the SFP port I get a green light on the Meraki and same goes for the Brocade. However, we get no network connections. We are using the Cisco SFP modules and I have it on the native VLAN for both.

Any ideas or advice would be greatly appreciated! Thanks!
