Console(config-if)# spanning-tree portfast
spanning-tree link-type
The spanning-tree link-type Interface Configuration mode command overrides the
default link-type setting determined by the duplex mode of the port and enables
Rapid Spanning Tree Protocol (RSTP) transitions to the forwarding state. Use the
no form of this command to restore the default configuration.

no spanning-tree link-type
Parameters
•
point-to-point —Indicates that the port link type is point-to-point.
