• Port Role—Displays the behavior of the port.
• Designated Bridge ID—Displays the bridge priority and the MAC address
of the designated bridge.
• Designated Port ID—Displays the priority and interface of the selected
port.
• Designated Cost—Displays the cost of the port participating in the STP
topology. Ports with a lower cost are less likely to be blocked if STP detects
loops.
• Forward Transitions—Displays the number of times the port has changed
from the Blocking state to Forwarding state.
• Speed—Displays the speed of the port.
• LAG—Displays the LAG to which the port belongs. If a port is a member of
a LAG, the LAG settings override the port settings.
Click Apply. The interface settings are modified, and the switch is updated.
Rapid Spanning Tree Protocol (RSTP) detects and uses network topologies that
enable 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. The STP Status and
Global Settings Page displays. Enable RSTP.
Click Spanning Tree > RSTP Interface Settings. The RSTP Interface Settings
Page opens:
Select a port. (Activate Protocol Migration is only available after selecting the port
connected to the bridge partner being tested.)
