VLAN - Multiple Trunk Port

RouterOS General
1

Hello Dears,

I have one CRS328-4C-20S-4S+RM and 15 CRS112-8P-4S-IN.
I need to configure 4 VLANs and these 4VLANs need to communicate with the 15 CRS112-8P-4S-IN through the SFP ports.
The problem is that the CRS328-4C-20S-4S + RM only communicates with one CRS112-8P-4S-IN. For example, it only communicates with the SFP1 port CRS112-8P-4S-IN and when I turn off the SFP1 port, it starts communicating with the SFP2 port…and so and so
I would like you to help me how to create multiple trunk ports to communicate with several other CRS112-8P-4S-IN to behave like a switch.
Thank you in advance for your help.

So are you saying you have a star topology with the CRS328 in the centre and those CRS112’s are not connected to each other, and nevertheless all the traffic only goes via a single port of the CRS328? If not, can you post a drawing of your actual topology and an export of the configurations of the switches?
