The ports are configured in switch settings (HP Procurve 2530-48G) in same trunk group (TrkX) and trunk group type is set as LACP. /proc/net/bonding/bond0 also shows that the three ports belong to same aggregator and bandwidth tests also support this. In my understanding Procurve's trunk group is pretty much the same as etherchannel in Cisco's terminology. The bonded link comes always up properly, but handling of links going down is the problem. Are there known differences between different vendors there? Veli-Matti
