Trying to setup an ip for the cluster and for ceph - Network questions

I have three Minisforum MS-01 units and am trying to set up those in a cluster. I am using three of the four ethernet ports (both 10G SFP+ ports in a LACP and the Intel vPro port for management). The Intel vPro management port is in the MNGT vlan 100, and I want to use the LACP for trunking.

I am trying to create separate IPs (similar to VMkernel ports in vCenter)—one for Ceph and one for the cluster. I have created the Linux VLAN with the IPs using the bridge connected to the LACP, but it is not working. What am I doing wrong here? Any help would be appreciated. I will also put a screenshot from Proxmox as well as a copy of the interfaces file.

Still having an issue with this. I can do the complete setup with installation and adding all three to the cluster. As soon as I first reboot a host, it is unreachable. I have tried a few things in some other forums, including setting the interfaces to static tied to the mac addresses just in case that was the issue, thanks to the guide here that made it easy. I have also double-checked the interfaces as well as the vlans and trunks on the switch. What am I missing here.
