WebMar 21, 2015 · For 802.1w, a TC will occur if a port moves into a forwarding state (not a blocking state). So that means, if a user restarts their computer or any other device when it begins forwarding, if it is not configured for PortFast, then it will trigger a TCN. This TCN will propagate through 802.1w devices causing the devices that receive to flush ...
WebFeb 9, 2024 · Rapid Spanning Tree Protocol (RSTP; IEEE 802.1w) can be seen as an evolution of the 802.1D standard more than a revolution. The 802.1D terminology remains primarily the same.
