• Last Topology Change—The time interval that elapsed since the last
topology change occurred. The time is displayed in a days/hours/minutes/
seconds format.
Click Apply. The switch is updated with the STP Global 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 configuration entered on this page is active for all flavors of the STP protocol.
To configure STP on an interface:
Click Spanning Tree > STP Interface Settings. The STP Interface Settings Page
displays.
Select an interface and click Edit. The Edit Interface Settings Page displays.
Enter the parameters
• Interface—Select the port number 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 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. 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.
• 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.
