PortFast allows an interface to transition quickly to the forwarding state.
Consider the following when configuring PortFast:
Do not enable PortFast on ports that connect to other devices.
PortFast only needs to be enabled on ports that connect to workstations or PCs. Repeat this configuration for every port connected to workstations or PCs.
Enabling PortFast on ports can cause temporary bridging loops, in both trunking and nontrunking mode.
If BPDUs are received on a PortFast- enabled interface, the interface loses the edge port status unless it receives a
shutdown/no shutdown command.
PortFast immediately puts the interface into the forwarding state without having to wait for the standard forward time.
