Specifying Whether the
Link Connected to a Port
Is Point-to-point Link
A point-to-point link directly connects two switches. If the roles of the two ports at
the two ends of a point-to-point link meet certain criteria, the two ports can turn
to the forwarding state rapidly by exchanging synchronization packets, thus
reducing the forward delay.

You can determine whether or not the link connected to a port is a point-to-point
link in one of the following two ways.
