I've got my 10G setup with core switch as CRS305-1G-4S+ (sw1) and delivery switch as CSS610-8G-2S+ (sw2) with cat 6e (<15m) connected with SFP+ S+RJ10 (Cabinet link). I'm using VLANs, as seen in screenshots. Core switch have ONU uplink to internet provider, and connected to 10G NAS and core router.
Well, it's target configuration, and I can't make it work properly. At sw2 I have Port 8 and SFP+1 as identical setup, as seen on screens. When sw1 connected to sw2 via Port8 (1G), it works perfect. When I move connection to SFP+1 (10G), I've got immediately "connection lost" with both switches. I'm sure all hardware and cables are good, seems like it have some wrong settings.
Please help me find where I am wrong? How to get them connected with 10G link?
