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.
