I'm hoping I'm just missing something easy with spanning-tree, but here is what I have:
I have 9 Aruba S2500 switches, 6 in the first stack and 3 in the other. A Palo Alto serving up 5 VLANs to the first Aruba stack (6 switches). From there I have the other Aruba stack that is connected via 10Gb to the first stack.
On the 10Gb port connecting the 2 stacks I have all VLANs allowed via a trunk and the VLANs are configured the same on both stacks. On the second stack I can't access the first stack's web UI, and same going from the first stack to the 2nd. I'm guessing I forgot something stupid, and I hope someone has an idea of what that is.
Thanks!
