To prevent loops from occurring in a network, the PortFast mode is supported only on nontrunking access ports because these ports typically do not transmit or receive BPDUs. The most secure implementation of PortFast is to enable it only on ports that connect end stations to switches. Because PortFast can be … See more PortFast causes a switch or trunk port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states. You can use PortFast on switch or trunk ports … See more BPDU filtering allows you to avoid transmitting BPDUs on PortFast-enabled ports that are connected to an end system. When you enable PortFast on the switch, spanning tree … See more BackboneFast provides fast convergence in the network backbone after a spanning tree topology change occurs. A switch detects an indirect link failure (the failure of a link to which the switch is not directly connected) when the … See more UplinkFast provides fast convergence using uplink groups in the network access layer after a spanning tree topology change.
