Hi
I have a problem stacking bonding + vlan + bridge, typically my servers
has two nic attached to two switch, one per nic, so I use bond in active-
passive configuration, on top of this I create vlans and a bridge for vlan
On ubuntu my network configuration are like this
auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_mode active-backup
bond_primary eth0
bond_miimon 100
auto br18
iface br18 inet static
address x.x.x.243
netmask 255.255.255.0
gateway x.x.x.254
bridge_ports bond0.18
bridge_fd 0
bridge_maxwait 0
auto br23
iface br23 inet manual
bridge_ports bond0.23
bridge_fd 0
bridge_maxwait 0
and so on
This machines are used as host for virtual machine, so vm are attached to
one or more of these bridge If either eth0 and eth1 are up there are lots
of this message in syslog
bond0.18: received packet with own address as source address
Maybe you have a virtual machine that's sourcing frames with a duplicate
MAC address? Does brctl showmacs <brX> look sensible?
Also, that could be a mismatch in your bond configuration between you and
the switch, although I don't know of a particular scenario where that would
happen. Maybe you're sending BDPU packets out towards the switch and you
have STP enabled on it?
