Hey, as i said: LACP is configured on my switches only. 2x HP Switches are connected to each other with 4x 1Gbe in a LACP Trunk. My Proxmox hosts are connected with 1 Gbe to each Switch and the Bonding interface has mode 6 (balance-alb)

Still valid is that lacp is just for a lag(l2 bonding) link between to l2 devices. If your switches are stacked they should be seen as one l2 device. if not, you cannot bond and use lacp. You need IP multipath to use the whole bandwidth of both links.

Both are connected with 4x 1Gbit with a LACP Trunk to each other – Working as expected. Now my Problem, I configured all my hosts with Bond Mode 6 and conncted 1 NIC to Switch One and the other to Switch Two Sometimes I got packetloss and see a Kernel error like this: vmbr0: received packet on bond0 with own address as source address (addr:0c:c4:7a:aa:5c:e4, vlan:0) Some hosts are working pretty well and some has Packet Loss. After adding some “rules” to a host which has loss the error messages disappear but the loss (less loss) still exists. Is there any special hint what can be the matter? When I change to active/passive mode all is fine. This is my interfaces config which has packetloss: auto lo iface lo inet loopback iface eno1 inet manual iface eno2 inet manual auto bond0 iface bond0 inet manual slaves eno1 eno2 bond_miimon 100 bond_mode 6 auto vmbr0 iface vmbr0 inet static address 10.0.2.111 netmask 255.255.255.0 gateway 10.0.2.1 bridge_ports bond0 bridge_stp off bridge_fd 0 bridge_maxage 0 bridge_ageing 0 bridge_maxwait 0 I am absolutely without any glue ☹ tested a lot and nothing really helps to solve this problem. -- Grüsse Daniel _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
