Configuring the Spanning Tree Protocol Defining Spanning Tree Interface Settings 13 Defining Spanning Tree Interface Settings The STP Interface Settings page enables you to configure STP on a per-port basis, and to view the information learned by the protocol, such as the designated bridge. The defined configuration entered is valid for all flavors of the STP protocol. To configure STP on an interface: STEP 1 Click Spanning Tree > STP Interface Settings. The STP Interface Settings page displays. STEP 2 Select an interface and click Edit. The Edit Interface Settings page is displayed. STEP 3 Enter the parameters • Interface-Select the Port or LAG on which Spanning Tree is configured. • STP-Enables or disables STP on the port. • Edge Port-Enables or disables Fast Link on the port. If Fast Link mode is enabled on a port, the port is automatically set to Forwarding state when the port link is up. Fast Link optimizes the STP protocol convergence. The options are: - Enable-Enables Fast Link immediately. - Auto-Enables Fast Link a few seconds after the interface becomes active. This allows STP to resolve loops before enabling Fast Link. - Disable-Disables Fast Link. NOTE It is recommended to set the value to Auto so that the switch sets the port to fast link mode if a host is connected to it, or sets it as a regular STP port if connected to another switch. This helps avoid loops. • BPDU Handling-Select how BPDU packets are managed when STP is disabled on the port or the switch. BPDUs are used to transmit spanning tree information. - Use Global Settings-Select to use the settings defined in the STP Status and Global Settings page. - Filtering-Filters BPDU packets when Spanning Tree is disabled on an interface.
