Configuring Spanning Tree Defining STP on Interfaces Network administrators can assign STP settings to specific interfaces using the STP Interface Settings. The Global LAGs section displays the STP information for Link Aggregated Groups. To assign STP settings to an interface: 1. Click Layer 2 > Spanning Tree > Interface Settings. The STP Interface Settings page opens: STP Interface Settings The STP Interface Settings contains the following fields: ❏ Ports - Displays STP interface settings for ports. ❏ LAGs - Displays STP interface settings for LAGs. ❏ Port - The interface for which the information is displayed. ❏ STP - 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. ❏ 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. ❏ 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. Embedded Web System User Guide www.hp.com 9-5
