WebThe PortFast and Bridge Protocol Data Unit (BPDU) Guard features enhance network reliability, manageability, and security for Layer-2 Spanning Tree Protocol (STP) . Some … 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.

WebUse PortFast edge on Layer 2 access ports connected to a single workstation or server to allow those devices to connect to the network immediately, rather than waiting for spanning tree to converge. Even if the interface receives a bridge protocol data unit (BPDU), spanning tree does not place the port into the blocking state.

WebNov 30, 2016 · Portfast allows the ports to immediately be set back to the forwarding state and prevents the link state changes that occur on ESX/ESXi hosts from affecting the STP topology. Setting STP to Portfast prevents the 30-50 second loss of network connectivity. The command to set STP to Portfast depends on the model of the switch.
