Bug Description
Binary package hint: linux-image-
- When a VLAN inferface is created from a Bridge interface, the resulting vlan interface with IP addresses etc. configured does not work.
- example /etc/network/
# The loopback network interface
auto lo
iface lo inet loopback
# The Bridge first ...
auto br0
iface br0 inet manual
bridge_ports eth0 eth1
bridge_stp on
# Vlans on the Bridge ...
auto vlan1
iface vlan1 inet static
address 10.1.1.1
netmask 255.255.255.0
network 10.1.1.0
broadcast 10.1.1.255
gateway 10.1.1.254
auto vlan2
iface vlan2 inet static
address 10.1.2.1
netmask 255.255.255.0
network 10.1.2.0
broadcast 10.1.2.255
- test with vlan interfaces directly on eth0 instead of br0 performs OK.
- issue seems to be reported also on LKML and a patch has been accepted to be applied by David Miller : please see http://
- this construction is used for redundancy
