Proxmox V-Lan Aware Bridges

[crudolphy]

I currently have the following setup:
vmbr0 - Vlan aware = yes - port = eno1 - CIDR = 192.168.10.X/24 - Gateway = 192.168.10.1
vmbr1 - Vlan aware = yes - port = eno2

vmbr0 with 192.168.10.X is the ip address of the proxmox server itself.
vmbr1 is Vlan aware but no specific ip address or gateway is set on this bridge.

As you can see this uses (2) physical 1Gbe ports (eno1 and eno2) I have eno3 and eno4 not being used at all.
I want to put eno3 into use by creating vmbr2 and assigning it to this port. I want to put eno4 into use by creating vmbr3 and assigning it to this port.

My question is, if I have other VM's that are part of Vlan 10 that utilize the 192.168.10.0/24 network can they use vmbr0 as it is currently setup? If I have to not specify a CIDR as I have done on vmbr1 and would do when setting up vmbr2 and 3 would I still be able to access the Proxmox server (both by command line/SSH) and the GUI?

Thanks for your help!

If you configured the IP address on vmbr0 directly, then this IP is for untagged traffic. vmbr0.10 is for using VLAN 10 on vmbr0. VLAN-aware just means that you can create those sub-interfaces. It also enables you to directly tag VLANs on the network device of the VM instead of having to create bridges/interfaces on the host directly for every VLAN you want to use.

Make sure you have out-of-band access to the PVE node before meddling with those network settings, since you could lose access to your PVE instance.
