Hi sir. I have some problem when I config LAG on SwOS.

from default config

Main SW :
LAG static group 1 Port 3-4
LAG static group 2 Port 5-6
LAG static group 3 Port 7-8
LAG static group 4 Port 9-10
LAG static group 5 Port 11-12

SW1 : LAG static group 1
port 1-2

SW2 : LAG static group 2
port 1-2

SW3 : LAG static group 3
port 1-2

SW4 : LAG static group 4
port 1-2

SW5 : LAG static group 5
port 1-2

it's can't working , all port LAG it's on same trunk 1.
How I can reslove it sir.

Hello, why are you configuring LAG ports as static? and the second one, to configure a LAG with SwOS it's like a LACP so it has some modes where those switches can negotiate the LAG port:

Passive: Place port in listening state, use LACP only when it's countrary port uses active LACP mode
Active: Prefer to start LACP regardless countrary port mode
Static: Place port in LACP mode=on

So if you want to configure a LACP link you need to get this combinations on both sides:
Active - Active
Active - Passive
On - On
