STP TCN Definition: STP TCN (Spanning Tree Protocol Topology Change Notification) is a message sent by a switch to notify other switches in a network of a change in the network topology, helping to avoid network loops.
STP TCN stands for Spanning Tree Protocol (STP) Topology Change Notification (TCN). It is a message sent by a switch in a network to inform other switches that a change in the network topology has occurred. This notification triggers a recalculation of the spanning tree, leading to the adjustment of network paths to prevent loops and ensure network efficiency and stability.
