I am trying to add a port to my openvswitch using "ovs-vsctl add-port br-lan eth1.6" but I keep getting the error "Error detected while setting up 'eth1.6': could not open network device eth1.6 (No such device)."
I have set up this eth1.6 and it appears under interfaces in Luci but when I run ifconfig -a in the shell eth1.6 does not appear.
I tried ifup eth1.6 but again I'm met with an error "Interface eth1.6 not found".
I am really unsure as to what I'm doing wrong.
Here's my configuration in /etc/config/network
config interface 'lan4'
option ifname 'eth1.6'
option proto 'static'
Any help would be much appreciated, thank you!
