Default Configuration
Portfast mode is disabled by default.
Command Mode
Global Configuration mode
Usage Guidelines
This command only applies to access ports.
NOTE: This command should be used with care. An interface with
PortFast mode enabled is moved directly to the spanning tree forwarding
state when linkup occurs without waiting for the standard forward-time delay.
Setting a port connected to another switch into PortFast mode may cause an
accidental topology loop and disrupt switch and network operations.
