The switch treats all ports in a trunk group as a single port. As
such, trunk ports will not be blocked by Spanning Tree (unless
a redundant link with higher STP priority is present).
Data transmitted to a specific host (destination address) will
always be transmitted over the same port in a trunk group.
This allows packets in a data stream to arrive in the same
order they were sent. A trunk connection can be made with
any other switch that maintains host-to-host data streams over
