> vlan 104 name EUCALYPTUS by port
> write memory

How to add a port to a VLAN

  • Ensure the port is not part of any other VLAN, if so, remove from the other VLAN first
> vlan 104
> untagged ethernet 0/1/25
  • To add one port to the VLAN 104 do:
> tagged ethernet 0/1/10/9
  • To add a block of port the VLAN 104 do:
> tagged ethernet 0/1/10 to 0/1/20
  • Save the changes
> write memory

  • On /etc/network/interfaces setup
auto eth0.100
iface eth0.100 inet static
	dns-search internal
	vlan-raw-device eth0

auto eth0.101
iface eth0.101 inet static
	vlan-raw-device eth0
  • Load 8021q module
# modprobe 8021q
# echo "8021q" >> /etc/modules
  • Assciate interfaces to a vlan
# vconfig add eth0 100
# vconfig add eth0 101
  • Restart the network interfaces
# service networking restart
