Hi JSONA,   First of all, the PowerConnect 27xx switches do not support the Spanning Tree Protocol. So it cannot define redundant ways and block packets. If you will create a loop like described, the packets will not filtered and will route endless through the switches until traffic will get this switch failed. Also the LAG feature is only a static feature in this switch and will provide bandwidth and failover (fault tolerance). As there is no LACP working, you cannot define redundant cabling. So you can create LAG to other switches but when configuring loop network, switch might be failed , if other switches also won't support spanning tree features.   Regards, Rodger
I am wondering if it would be possible to set up a fault-tolerant uplink between several Dell Powerconnect switches.  What I would like to have happen is, we have a Powerconnect 2724 with the majority of our servers connected to it.  There is one uplink from this switch, to the remainder of our network switches.  I would like to have two or four uplinks, such that if one uplink failed for some reason (port issue on a switch, someone accidently unplugged the wrong cable, squirrels ate through the cable, whatever) the connection to the servers is not lost, as it simply re-routes through one of the other uplinks. Basically, the server switch would have 4 uplinks, to 4 other switches, each of which would also be uplinked to each other.  I know if I simply plug cables in hoping this will work, without configuring the switch(es), I'll get a loop and all heck will break loose. It sounds like possibly a LAG *might* work, or a port-trunk configuration. Would this be correct, or would this cause more trouble? Thank, Jason A.
Fault-tolerant uplinks between switches?
