Configuring the Spanning Tree Protocol Configuring Rapid Spanning Tree Settings 13 Configuring Rapid Spanning Tree Settings 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 . To enter RSTP settings: STEP 1 Click Spanning Tree > STP Status and Global Settings. The STP Status and Global Settings page is displayed. Enable RSTP. STEP 2 Click Spanning Tree > RSTP Interface Settings. The RSTP Interface Settings page opens: STEP 3 Select a port. NOTE Activate Protocol Migration is only available after selecting the port that is connected to the bridge partner being tested. STEP 4 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. 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, the device communicates with it using RSTP. STEP 5 Select an interface, and click Edit. The Edit RSTP Interface setting page is displayed. STEP 6 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. - Enable-This port is an RSTP edge port when this feature is enabled, and is brought to Forwarding mode quickly (usually within 2 seconds). - Disable-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.

Configuring Rapid Spanning Tree Settings
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 .
To enter RSTP settings:
STEP 1
Click
Spanning Tree
>
STP Status and Global Settings
. The
STP Status and
Global Settings
page is displayed. Enable
RSTP
.
STEP
2
Click
Spanning Tree
>
RSTP Interface Settings
. The
RSTP Interface Settings
page opens:
STEP
3
Select a port.
NOTE
Activate Protocol Migration is only available after selecting the port
that is connected to the bridge partner being tested.
STEP
4
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. 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, the device communicates with it using RSTP.
STEP
5
Select an interface, and click
Edit
. The
Edit RSTP Interface setting
page is
displayed.
STEP
6
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.
-
Enable
—This port is an RSTP edge port when this feature is enabled, and
is brought to Forwarding mode quickly (usually within 2 seconds).
-
Disable
—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
