Problem with Lag AND Stack on 2ports on 2switches 728TXS

[Weise]

Hello,

I habe 2 switches configured as a stack. And I have configured a LAG with two ports of Switch1 und two ports of Switch2. My Server has got 4 NICs, all NICs are active and configured for LAG. If I connect 2 NICs to a LAG-port on Switch1 und a LAG-port on Switch2, everything is fine and I can ping my server. Also if I connect two NICs to two LAG-ports on one of the switches, it also works fine. If I add the third NIC to one of the LAG-ports, the connection to the server is lost. WHY? What can I do?

Server ist a ESXI5.1-Machine, VSpere Standard Switch is configured for "IP-Hash".

Thanks in advance,

Raphael

Thanks for your answer. I finally set up all one more time and suddenly everything was working fine. Expect, the switch needed one more restart.

Hi Weise,

Welcome to our community!

As per checking that you were able to configure 2 LAGs and it is working properly. Have you ever tried to check if the ports are not members of the previous LAG? May you be able also to try if you can just connect the 3rd LAG as 2nd? Meaning you have to remove the other one just to isolate?
