[Bug 1041070] Re: 802.3ad bond interface have show high RX dropped packets
This is related to the bonding mode and _not_ a bug. The bonding module will drop duplicate frames received on inactive ports, which is normal behavior. [0] Overall the packets should be getting into the machine without problems since they are received on the active slave. To confirm this do the following 1) Check dropped packets from all interfaces. So if eth0/eth1 are connected to bond0, we may see dropped packets for bond0 and eth0, but not for eth1. This depends on which interface is the active interface. This can be checked using the following: cat /sys/class/net/bond0/bonding/active_slave So if the active_slave isn't dropping packets, and the inactive slave is dropping packets this is normal in 'active-backup' mode (or any mode where there is an inactive slave). 2) If we want both interfaces to not drop packets we can use 'all_slaves_active' bonding module parameter [0]. Check: cat /sys/class/net/bond0/bonding/all_slaves_active, it should default to 0 which means drop frames on the inactive slave. If we set this to 1, we will no longer drop frames: echo 1 | sudo tee /sys/class/net/bond0/bonding/all_slaves_active ** Changed in: linux (Ubuntu) Status: Expired = Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bridge-utils in Ubuntu. https://bugs.launchpad.net/bugs/1041070 Title: 802.3ad bond interface have show high RX dropped packets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/1041070/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I'm seeing the same thing. Yes, my switch is configured for 802.3ad. The bond comes up but drops 2pps consistently.

[Bug 1041070] Re: 802.3ad bond interface have show high RX dropped packets
Thanks for taking the time to report this bug in Ubuntu. As you are configuring with bond-mode 802.3ad this will also require configuration on the switch your server is connected to - please can you confirm that this has been done? Configuration of the switch will depend on vendor so unfortunately I can't give you an easy way to check.
