1.Click Advanced Setup > Spanning Tree > STP > Interface Settings. The STP Interface Page opens:
Figure 86: STP Interface Page
The STP Interface Page contains the following fields:
•Port — The interface for which the information is displayed.
•STP Status — Indicates if STP is enabled on the port. The possible field values are:
–Enabled — Indicates that STP is enabled on the port.
–Disabled — Indicates that STP is disabled on the port.
•Fast Link — Indicates if Fast Link is enabled on 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 optimizes the STP protocol convergence. STP convergence can take
•Root Guard — Prevents devices outside the network core from being assigned the spanning tree root.
•Port State — Displays the current STP state of a port. If enabled, the port state determines what forwarding action is taken on traffic. Possible port states are:
–Disabled — Indicates that STP is currently disabled on the port. The port forwards traffic while learning MAC addresses.
–Blocking — Indicates that the port is currently blocked and cannot forward traffic or learn MAC addresses. Blocking is displayed when Classic STP is enabled.
