Yes, the log clearly shows that the LACPDUs are sent, at least bonding thinks so. I just checked for received mcast packages on the switch: yes, they come in frequently on all four ports. Though I can't check or Slow_Protocols_Multicast address specifically. > If the switch is configured, you may want to also check to see > if it has counters for LACPDUs sent and received.

I did not find a dedicated stat for received LACPDUs. I tried some settings on the switch webinterface. Interesting: if I toggle the 'Admin Flow Control' from either 'enabled' to 'autonegotiation' I immediately receive the switch LACPCUs, see: bonding: ad_tx_machine() 1210: Sent LACPDU on port 1 bonding: bond_3ad_rx_indication() 2175: Received LACPDU on port 1 bonding: ad_rx_machine() 1123: Rx Machine: Port=1, Last State=6, Curr State=6 If I then disable the bond (rmmod inclusive) and then enable the bond again there are no received LACPDUs from the switch.

Yes, I already saw in the code that IFF_NOARP was expected.
