2. Manual Configuration:

This approach involves manually configuring the VLANs on each individual Harvester node using the CLI. This includes editing network configuration files and setting up the VLAN interfaces. While more complex, it offers greater flexibility and control.
Here are the steps for manual configuration:

A. On each Harvester node:

SSH into the node.
Access the network configuration directory: cd /etc/sysconfig/network
Create a file for each NIC you want to configure for VLANs:
For example, if your NICs are named enp3s0 and enp4s0, create files named ifcfg-enp3s0 and ifcfg-enp4s0.
In each NIC file, set the following parameters:
STARTMODE='hotplug'
BOOTPROTO='none'
Create a file for your bond interface:
For example, name it ifcfg-harvester-vlan.
In the bond interface file, set the following parameters:
STARTMODE='auto'
BONDING_MASTER='yes'
BOOTPROTO='dhcp'
BONDING_SLAVE_0='<NIC1 name>' (e.g., enp3s0)
BONDING_SLAVE_1='<NIC2 name>' (e.g., enp4s0)
BONDING_MODULE_OPTS='miimon=100 mode=balance-tlb'
DHCLIENT_SET_DEFAULT_ROUTE='yes'
Edit the file ifcfg-harvester-mgmt:
Set BOOTPROTO='none' to prevent IP address conflicts.
Bring up the interfaces:
sudo wicked ifup <NIC1 name>
sudo wicked ifup <NIC2 name>
sudo wicked ifup harvester-vlan
Verify the configuration:
ip -br a
Refresh the Harvester UI:
Select the host again to pick up the new bond.
If it doesn't update, reboot the node.
B. In the Harvester UI:

Go to Advanced > Networks.
Click Create to create a new VLAN network for each VLAN ID you want to configure.
Specify the desired name and VLAN ID for each network.
Go to Hosts > <Host Name> > Network.
Select the desired VLAN network for the host's cluster network.
Save the changes.
