User Guide - OWL VLANs
This guide shows how to add VLAN functionality to OWL devices via simple startup-scripts.
Add Startup Script
Add the following three lines to the startup script:
ip link add link eth1 name eth1.10 type vlan id 10
ip addr add dev eth1.10 192.168.10.8/24 brd 192.168.10.255
ip link set dev eth1.10 up
Explanation:
ip link add link eth1 name eth1.10 type vlan id 10
• ip link add - command to add a new link
• link eth1 adds the VLAN to the Secondary Ethernet Interface
• name eth1.10 gives a name to this vlan interface which is used in the following commands, but
convention is <linked ethernet>.<vlan id>
• type vlan id 10 creates a VLAN with ID 10
ip addr add dev eth1.10 192.168.10.8/24 brd 192.168.10.255
• ip addr add - command to add an IP address to an interface
• dev eth1.10 - add the IP address to the interface named eth1.10 (freely chosen with the link add
command before)
• 192.168.10.8/24
• assigns the management IP address 192.168.10.8 on this VLAN
• tells the system that the subnet network mask is /24 (equivalent to 255.255.255.0)
• brd 192.168.10.255 - optional - tells the system the broadcast IP address of this subnet
ip link set dev eth1.10 up
• Enables the interface named eth1.10
