Command Modes Interface configuration mode
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
auto Sets the link type based on the duplex setting of the interface.
point-to-point Specifies that the interface is a point-to-point link.
shared Specifies that the interface is a shared medium.
