I have a stack of 5 X440-48p G2 switches. I want to have a LAG uplink to the network and am wondering if the 2 ports should be on the master and backup? I configured port 1:48 & 5:48 in the LAG but node 5 is just a standby node. Should I fix the LAG so it is ports 1:48 (master) & 2:48 (backup) or does it not matter?

Hi, That does not matter. Any port of any node can participate in a LAG

That's what I thought, I just didn't know if it was beneficial to have them on the master and backup. Thank you for your help.

The master/backup roles protect the stack itself and as long as the primary/secondary ports of your LAG are in different switches in the stack, you'll be protected.
