I have two 1950 12XGT 4SPF+ switches. I bought those specific switches because I have 5 servers that I want to network using pairs of 10G connections (via LACP to get 20G). I understand that each 12XGT only allows 4 pairs of ports to support LACP at once (which is why I bought 2 of the switches giving me 8 pairs to work with).
I started off with one 12XGT connected to 4 server each of which was using a pair of ports in LACP plus a 1950 24G 2SPF+ 2XGT that was just plugged into 1 regular port with a jumper (for iLo and other non 10G items). Everything worked great with this setup.
I added a 5th server and discovered the limit of 8 ports being used for LACP. I then purchased a second 12XGT and a pair of the stacking cables (3M SPF+ cables recommend by HPE support). I attempted to stack the two 12XGT switches using the IRF instructions from HPE (and instructions found elsewhere). I have not been able to get it to work and I can't figure out why.
Can someone here link me to instructions that are correct for this process?
Is my 1950 24G 2SPF+ 2XGT being plugged in using a regular (non SPF) cable and not being configured for stacking causing a problem?
Thanks
