Re: [Xen-API] XCP 1.1 OVS and active-backup mode seeing traffic on both interfaces

Thank you. Why was active-backup architected to accept packets on all interfaces? Depending on your physical architecture that has the potential to play havoc with the ARP tables in the switches.

I'll try installing a newer version of OVS tomorrow.

Thanks again.  I really appreciate your help.

Yes, you can install a newer version of OVS on XCP.  The
instructions you need are in INSTALL.XenServer.

I wouldn't say that active-backup bonding in XCP 1.1 is
"useless".  It works fine in many use cases, just not in yours.

the requirement that a bonded management interface be in active-backup

to the same switch (or stack) I have the bond in active-backup mode:

The version of OVS in XCP 1.x accepts incoming packets on all
interfaces of active-backup bonds.  We changed this behavior in
newer versions of OVS.
