Vlan management

[Arthur777]

Hello, I'm setting up a home lab. I have my Proxmox server connected to two switches: one for Ceph with the subnet 192.168.1.0/24 and another connected to a different switch with the network 10.0.90.0/23. I tried configuring this setup to create a management VLAN, but I can no longer access the address 10.0.90.208 when I do so. I've configured the port of my switch as a trunk and accepted VLAN 240. Any idea ?



Thanks in advance.

Image quality is too bad to read your network config.
But looks like your gateway is outside of your management subnet.
Did you set up inter subnet/vlan routing? Without a router routing between your subnets you won't be able to access your PVE unless your client is using an IP in that 10.0.90.0/23 subnet too.

Hello, excuse me for the poor quality of my photo. Here is the configuration written out. As for the gateway, it is indeed located within the correct subnet, and my laptop has an address within this subnet.

auto lo
iface lo inet loopback

Iface enp3s0 inet manual

auto enp1s0f0
iface enp1s0f0 inet manual

auto enp1s0f1
iface enp1s0f1 inet manual

auto bond0
iface bond0 inet static
address 192.168.1.2/24
bond-slaves enp1s0f0 enp1s0f1
bond-node balance-alb


auto vmbr0
iface vmbr0 inet manual
bridge-ports enp2s0
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4054


auto vmbr0.240
iface vmbr0,240 inet static
address 10.0.90.208/23
gateway 10.0.91.245

Then the network config looks fine if that "iface vmbr0,240 inet static" is actally a ".", your "bridge-ports enp2s0" is actually "enp3s0", your switches port is tagged with VLANID 240 and you are not planning to have any guests using that bond.

I will double-check that properly to make sure.

your switches port is tagged with VLANID 240 and you are not planning to have any guests using that bond.

For the configuration at the switch level, I simply set the port connected to the Proxmox server as follows:
switchport mode trunk
switchport trunk allowed vlan 240
