This kind of configuration can work with switches that offer spanning tree or MLAG. But the 27xx series switches do not offer these features. With this kind of setup there is a loop that will cause a continual broadcast storm that will wreak havoc on the network. Your best form of redundancy will be link redundancy from switch to switch, but you wont be able to get switch redundancy with the 27xx switches.  Switch1   Switch2          \\       //         Switch3 Or Switch1 =  Switch2                  //         Switch3 Or Switch1 = Switch2          \\                Switch3 Cheers
Hi, I have several Dell 2724 switches that I would like to set up redundantly. I have joined two 2724s with a trunk. I would now like to connect the access switch with one connection to each of the two trunked switchs. One cable in switch1 everything works. Put second cable in switch2 and all breaks loose. Switch1=Switch2 (LAG) \       / Switch3  Can someone tell me if this works and how? Thanks
