Hi Guys
I have problem with LACP between two 1960 stacks. One stack with two Aruba 1960 12XGT 4SFP+ switches is connected to second stack with two Aruba 48G 2XGT 2SFP+ switches. Stacks working without problem (stacks are connected trought SFP+ DAC cables) but I can´t connect both stack together with LACP uplink.
I created trunks with two ports on both switches with LACP connection, but both ports on Backup switches not working at all and ports working only on Conductors. I tried to change LACP Trunk to Static, behavior of ports is same, they don´t even have a link and not working at all. When I connect all four uplink ports on stack without Trunk, they work without problem.
On this video, all four ports are work on LACP Trunk.

Firmware on both stacks is 2.8.0.17.
Do you have any clue, where is the problem ?
Do you recommended to connect uplink on both Stacks together without LACP Trunk ?
Thank you
David

EDIT:
The problem was in one of the stacks where the configuration was probably written incorrectly (I don't know why, but editing configuration from web mgmt didn't work) and after a factory reset the LACP between the two stacks behaves correctly.
