Defining STP Port Settings

The STP Port Settings page contains fields for assigning STP properties to individual ports. To open the STP Port Settings page, click Switch→ Spanning Tree→ Port Settings in the tree view.

Figure 7-17. STP Port Settings

•Select a Port — Port on which STP is enabled.

•STP — Enables or disables STP on the port.

•Fast Link — When selected, enables Fast Link mode for the port. If Fast Link mode is enabled for a port, the Port State is automatically placed in the Forwarding state when the port link is up. Fast Link mode optimizes the time it takes for the STP protocol to converge. STP convergence can take 30-60 seconds in large networks.

•Root Guard — When checked, prevents devices outside the network core from being assigned the spanning tree root.
