Hi *,
I'm running into a problem configuring bonding on an HP DL 360 G4p, running 4.3 + tg3 driver version 3.43f. I'm connecting eth0 and eth1 to a Cisco 2948 (CatOS 8.1(3)) and receiving flapping notices. The ethernet address is that of the primary interface. I have tried several different modes, including balance-rr (0), active-backup (1), and balance-alb (6). All have the same problem. More detailed info follows.

I found http://www.uwsg.iu.edu/hypermail/linux/net/0605.1/0008.html but it wasn't very helpful. Other users seem to have it "just work."
If anybody has run into this, I would appreciate some pointers.
Thanks,
