Usage Guidelines
Rapid Spanning Tree Protocol Plus (RSTP+) fast transition works only on point-to-point links between two
bridges.
By default, the switch derives the link type of a port from the duplex mode. A full-duplex port is considered
as a point-to-point link while a half-duplex configuration is assumed to be on a shared link.
If you designate a port as a shared link, RSTP+ fast transition is forbidden, regardless of the duplex setting.
Examples This example shows how to configure the port as a shared link:
Switch(config-if)# spanning-tree link-type shared
