It can be left on but if you can disable it on the ports that you are using for lagg then that should help. If you can't turn it off on a per-port basis and you don't have a meshed switch topology then just turn spanning tree off. I think whats happening is spanning tree is seeing a topology change and forcing a renegotiation of the tree, which has the side effect of stopping packet forwarding. You could also turn down the spanning tree timers, but there would still be a pause in the forwarding of packets Regards, Gary
