Rapid Spanning Tree Protocol (RSTP) enables a faster STP convergence without creating
forwarding loops.
The RSTP Interface Settings page enables you to configure RSTP per port. Any configuration
that is done on this page is active when the global STP mode is set to RSTP or MSTP.
To enter RSTP settings:
Click Spanning Tree > STP Status and Global Settings.
Enable RSTP.
Click Spanning Tree > RSTP Interface Settings. The RSTP Interface Settings page appears.
Select a port.
Activate Protocol Migration is only available after selecting the port that is
NOTE
connected to the bridge partner being tested.
If a link partner is discovered by using STP, click Activate Protocol Migration to run a
Protocol Migration test. This discovers whether the link partner using STP still exists, and if so
whether it has migrated to RSTP or MSTP. If it still exists as an STP link, the device continues
to communicate with it by using STP. Otherwise, if it has been migrated to RSTP or MSTP, the
device communicates with it using RSTP or MSTP, respectively.
Select an interface, and click Edit.
Enter the parameters:
• Interface—Set the interface, and specify the port or LAG where RSTP is to be
configured.
• Point to Point Administrative Status—Define the point-to-point link status. Ports
defined as Full Duplex are considered Point-to-Point port links.
- Enabled—This port is an RSTP edge port when this feature is enabled, and is
brought to Forwarding mode quickly (usually within 2 seconds).
- Disabled—The port is not considered point-to-point for RSTP purposes, which
means that STP works on it at regular speed, as opposed to high speed.
- Auto—Automatically determines the device status by using RSTP BPDUs.
• Point to Point Operational Status—Displays the Point-to-Point operational status if
the Point to Point Administrative Status is set to Auto.
