Received packet with own address as source address

[dllewellyn]

Hi, I am newbie with Proxmox (my son who is at college now set it up for me). I created a VM for FreePBX (VOIP PBX) which seems to be working fine, but I get audio dropouts for 1-3 seconds every minute or so. I have been trying to trace down the source and wonder if it might be related to Proxmox, the server which has 4 gigabit ports bonded together and the smart switch (Trendnet TL-SG1016DE) configuration. On the Proxmox Syslog, I see a bunch of errors such as

Sep 28 11:32:49 proxmox kernel: fwln106i0: received packet with own address as source address
Sep 28 11:33:52 proxmox kernel: eth2: received packet with own address as source address
Sep 28 11:34:00 proxmox kernel: eth3: received packet with own address as source address
Sep 28 11:34:03 proxmox kernel: eth0: received packet with own address as source address

Sep 28 11:36:05 proxmox kernel: eth3: received packet with own address as source address
Sep 28 11:36:08 proxmox kernel: eth0: received packet with own address as source address

Screenshot of Network config in Proxmox.



Most of the traffic appears to go through only one ethernet port. Ports 9,10,11,12 go to the Supermicro computer that is running Proxmox.

Thanks for your help!

Don't see a bound interface! Disconnect 3 cables from switch!

Thanks for responding. Even with only one ethernet port connected, I still get

Sep 29 08:44:53 proxmox kernel: eth0: received packet with own address as source address
Sep 29 08:45:44 proxmox kernel: fwln106i0: received packet with own address as source address
Sep 29 08:46:58 proxmox kernel: eth0: received packet with own address as source address
Sep 29 08:47:49 proxmox kernel: fwln106i0: received packet with own address as source address

What should I do to make the cards bound? Do I also need to change anything on my switch?

 

[proxtest]

if u get this error u did wrong cabeling. it's a star wiring and not a ring! or your switch config is wrong!
delete vmbr1 vmbr2 vmbr3 also.

there are different types of bonding, why u need this at this time? KISS!

reset the switch (no trunk), use only one card and it should work.

With only et0 plugged into switch, I still get

Sep 29 08:44:53 proxmox kernel: eth0: received packet with own address as source address

I am using commercially made CAT6 cables. Server plugs into a Trendnet TL-SG1016DE switch that doesn't have any trunks defined or anything set. Switch is using default settings. All of the cables in the network are CAT6.

Post your /etc/network/interface

I have also tried changing switches, unplugging other hubs, shutting down every VM and even rebooting the server and Proxmox, but same problem remains. Network config is

Looks like problem is solved now. Upgraded from Proxmox 3.3 to 4.3 and error stopped. No idea what the problem was, but it wasn't the switch or cable.
