LAG Membership Each device supports up to 32 LAGs per system, and eight ports per LAG. When you add a port to a LAG, the port acquires the LAG's properties. If the port cannot be configured with the LAG's properties, it is not added to the LAG and an error message is generated. If the first port joining the LAG cannot be configured with the LAG settings, the port is added to the LAG, using the port default settings, and an error message is generated. Since this is the only port in the LAG, the entire LAG operates with the port's settings, instead of the LAG's defined settings.
