28.10.6 Link Type Settings

Link types represent the connection status of a port. The connections between switches must be point-to-point to perform high-speed status transitions for Rapid PVST+, Rapid STP for Single Spanning Tree, or Multiple Spanning Tree. For shared types, high-speed status transitions are not performed, and status transitions are performed by timer as with PVST+ and STP for Single Spanning Tree.

Points to note

A connection status can be set for each port. If it is not set, point-to-point is used when the port is a full duplex connection, and shared is used when it is a half duplex connection.

Command examples

1. (config)# interface gigabitethernet 1/0/1

   (config-if)# spanning-tree link-type point-to-point

   Runs port 1/0/1 as a point-to-point connection.

Notes

For configurations where the actual network connection type is not a 1-to-1 connection, do not use this command to specify point-to-point. In configurations other than 1-to-1 connections, at least two Spanning Tree switches neighbor a single port.
