Let me show you an example of an indirect link failure and how spanning-tree deals with it: Take a look at the picture above. SW1 is the root bridge and the fa0/16 interface on SW3 has been blocked. Suddenly the link between SW1 and SW2 fails. UplinkFast provides fast convergence using uplink groups in the network access layer after a spanning tree topology change. An uplink group is a set of ports (per VLAN), only one of which is forwarding at any given time. Specifically, an uplink group consists of the root port (which is forwarding) and a set of … See more PortFast causes a switch or trunk port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states.
