Command History
Usage Guidelines
Fast transition (specified in IEEE 802.1w) functions 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.
Note
On a Cisco Nexus 5000 Series switch, port duplex is not configurable.
Examples
This example shows how to configure the port as a shared link:
switch(config-if)#
spanning-tree link-type shared
Related Commands
