Re: [ovs-discuss] Turn bridge into a HUB
Thanks! Both did the trick.

Re: [ovs-discuss] Turn bridge into a HUB
Thanks Ben, And how about vlan tags? Will it preserve them? Or should I set a "native vlan" for both in and out ports? There is no "regular vlan" on this bridge. It is for flooding only.

[ovs-discuss] Turn bridge into a HUB
Hello, I have a physical port receives traffic from mirrored ports in a physical (core) switch. I would like to pass these packets to multiple VMs (xen), replicating vlan tags when existing. With linux bridges, I set aging to 0 and, as it does not understand vlan tags, everything works. Now I want to setup the same situation with ovs. I'm still a newbie with ovs. Xen uses the /etc/xen/scripts/vif-openvswitch that allows me to specify tag and trunk argument when a vm port is added (not much besides that). As I might receive multiple vlans, I would like to not list all of them. I saw that flood_vlans might be useful. I simply need to flood all traffic from the physical port on every other port but the physical one, replicating vlan tags.
