Read more about Domotz’s Remote Network Monitoring Features.

 

Domotz supports monitoring of multi-VLAN network configuration through a variety of network installation options which include: Self Installation on a Raspberry Pi (i.e. your own Raspberry Pi device), Domotz Box, Windows, Linux, Synology etc.

 

This post will explain how to configure mutli-VLAN support via your own self-installed Ubuntu OS (including Ubuntu for Raspberry Pi):

 

1. Edit the file /etc/netplan/01-netcfg.yaml which is used by the current Ubuntu distribution version to configure the system network:

 

sudo nano /etc/netplan/01-netcfg.yaml

 

An example adding the VLANs 15 and 20:

 

network:
 version: 2
 renderer: networkd
 ethernets:
   eth0:     
     dhcp4: false
     addresses: [192.168.0.5/24]
 gateway4: 192.168.0.1
     nameservers: 
       addresses: [ "8.8.8.8", "8.8.4.4" ]
 vlans:
   vlan15: 
     id: 15 
     link: eth0
     addresses: [ "192.168.15.5/24" ]
   vlan20:
     id: 20
     link: eth0
     addresses: [ "192.168.20.5/24" ]

*Do NOT use TAB for indentation. Click here for more examples.

2. Save the file and run the command "netplan apply":

 

sudo netplan apply

 

UPDATE August 2022:

 

The newer netplan version will not accept 'gateway4'  key anymore, that has to be replaced with the 'routes' key now. The new configuration file should now be like this:

 

network:
 version: 2
 renderer: networkd
 ethernets:
   eth0:     
     dhcp4: false
     addresses: [192.168.0.5/24]
       routes:
       - to: default
         via: 192.168.0.1
     nameservers: 
       addresses: [ "8.8.8.8", "8.8.4.4" ]
 vlans:
   vlan15: 
     id: 15 
     link: eth0
     addresses: [ "192.168.15.5/24" ]
   vlan20:
     id: 20
     link: eth0
     addresses: [ "192.168.20.5/24" ]

When this is pasted in to nano I get this error

:~$ sudo netplan apply
/etc/netplan/01-netcfg.yaml:9:17: Invalid YAML: inconsistent indentation:
     nameservers

Hi @RUMBLE,

 

I am sorry for the lack of response, this is because you used some unsupported character or TAB's (always use spaces for indentation).

 

Here you find many other examples: https://netplan.io/examples 

 

Do not hesitate to reach out our support if you need further assistance: support@domotz.com (I promise we will be faster).
