      @mitzayapa Hi, have you configured your switch to enable LACP ?

      I use it on a debian 8 (in vmware esxi 5.5) with that interfaces config :

      auto bond0
      iface bond0 inet static
      	address 172.20.0.4
      	netmask 255.255.0.0
      	gateway 172.20.1.50
      	slaves eth0 eth1
      	bond_mode balance-alb
      	bond_miimon 100
      	bond_downdelay 200
      	bond_updelay 200

        I have seen slighlty slower speeds (between two actors) when using bonding, because when you enable bonding you also add a bunch of code between the OS and the network interface. But 50% loss is a bit much.

        Just looking at your bonding configuration it looks like there are a few things missing. What OS are you using here?

        Also what is your idea for using bonding? How many devices will you deploy at once?

          Ok, I see from the kernel you are using ubuntu.

          I also noticed that all of your network traffic is passing over p255p1 what is that network adapter?

              em1 is the builtin NIC , p255p1 is the one I added.

              Ive tested it for some days now , with more than one client , so can u tell me what should i remove/add to my config ?
              From the last reboot the server was at first connected through buildin NIC then after a few hours ive connected the second NIC

                Well, I think this line is in error
                bond-primary em1 p255p1
                Since you already have that defined for em1 or I would only select one, probably the internal one for primary.

                Secondly I think I would use bond mode 5 or if you have access to the switch setup LACP mode.

                Did you deploy only one client in the test above or more than one? The packets transmitted seem to indicate the second nic is not being used. If you had only two actors in the conversation I would understand the packet mismatch.

                  And why bond-primary em1 eth1?? You don’t have eth1 as ifconfig shows.

                  Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                    True , there´s no eth1 device in my config. Just delete it ?

                        I’d suggest this config:

                        auto em1
                        iface em1 inet manual
                          bond-master bond0
                          bond-primary em1
                        
                        auto p255p1
                        iface p255p1 inet manual
                          bond-master bond0
                        
                        auto bond0
                        iface bond0 inet static
                          bond-slaves em1 p255p1
                          bond-mode 2
                          bond-miimon 100
                          ...

                          @Sebastian-Roth In some of the ubuntu examples they always use bond-slaves none. Not sure why. I would agree with your setting.

                          As for the primary, I still think I would use the onboard nic for primary, but again I don’t know what a p255p network interface is. Also if the xor mode (bond mode 2) (not really intelligent but fast) isn’t properly sharing the bandwidth during 3 or more installs at the same time, I would switch to bond-mode 5 or setup lacp on the switch and use bond-mode 4.

                            The p255p is the second NIC I added to the server.

                            em1 - built in
                            p255p - 1gigabit ethernet card

                            auto em1
                            iface em1 inet manual
                              bond-master bond0
                              bond-primary em1
                            
                            auto p255p1
                            iface p255p1 inet manual
                              bond-master bond0
                            
                            auto bond0
                            iface bond0 inet static
                              bond-slaves em1 p255p1
                              bond-mode 2
                              bond-miimon 100
                              ... -> is there missing something or thats all ?

                              I used round robin, it gave both speed and resilience, however that was on an unmanaged switch.

                                @mitzayapa Sorry I was reading fast before I started my commute into work. I read p255p1 as your primary interface. I thought it was strange, but I’ve seen some pretty strange stuff in the last few days.

                                As for the bonding, what you have is correct, you still need to assign the normal IP address stuff to the bond0 interface.

                                At the very least these:

                                address 192.168.137.51
                                netmask 255.255.255.0
                                gateway 192.168.137.1

                                    @mitzayapa I agree that looks reasonable. Restart the network service and see what you have with ip addr show

                                    I do have to say I’ve only seen where they bond like adapters. This should work but now you have two network drivers loaded. Again not a problem, just not standard.

                                      It’s seem to be good, it’s not necessary to configure your p255p1 and em1 interfaces :

                                      # This file describes the network interfaces available on your system
                                      # and how to activate them. For more information, see interfaces(5).
                                      # The loopback network interface
                                      
                                      auto lo
                                      iface lo inet loopback
                                      
                                      # The primary network interface
                                      
                                      #auto em1
                                      #iface em1 inet manual

                                        Without configuring the p255p1 and em1 the network ainºt working.(as i have no connection to server)

                                        It works like this :

                                        auto em1
                                        iface em1 inet manual
                                          bond-master bond0
                                          bond-primary em1
                                        
                                        auto p255p1
                                        iface p255p1 inet manual
                                          bond-master bond0
                                        
                                        auto bond0
                                        iface bond0 inet static
                                          bond-slaves em1 p255p1
                                          bond-mode 2
                                          bond-miimon 100
                                          address 192.168.137.51
