Defining STP on Interfaces
Network administrators can assign STP settings to specific interfaces using the STP Interface Page. The Global
LAGs section displays the STP information for Link Aggregated Groups. To assign STP settings to an interface:
1. Click Advanced Setup > Spanning Tree > STP > Interface Settings. The STP Interface Page opens:
Figure 123: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.
• Root Guard — Prevents devices outside the network core from being assigned the spanning tree root.
• Port Fast — 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 30-60 seconds in large networks.
• 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.
• Port Role — Indicates the port role assigned by the STP algorithm in order to provide to STP paths. The pos-
sible field values are:
