two ports in a valid 2-port LAG on another device.

All the ports in a trunk group must be connected to the same device at the other end. For
example, a if port 1/4 and 1/5 in Device 1 are in the same trunk group, both ports must be
connected to a ports in Device 2 or in Device 3. You cannot have one port connected to Device
2 and another port connected to Device 3.
All LAG member properties must match the primary port of the LAG with respect to the
following parameters:
•
Port tag type (untagged or tagged port)
•
Port speed and duplex
•
QoS priority
To change port parameters, you must change them on the primary port. The software
automatically applies the changes to the other ports in the LAG.
Make sure the device on the other end of the trunk link can support the same number of ports
in the link.
