We are installing a Dell VRTX system and I'm having some trouble with the networking. There are 2 blades in the chassis with 2 NICs each. I have put the in 2 LAGs, 2 ports each. The VRTX has an 8-port switch on the chassis that is used to connect to the rest of the LAN. I am not sure if I should put all 8 ports in the same LAG with LACP, or create 2 LAGs with 4 ports each. We will be going to 2 powerconnect 5448 switches connected via fiber, 4 ports each. I have set up LAG 1 on each switch, but not sure if this will create a loop in the network. STP killed a switch when I tried this the first time.
