STP Mode Shows the Spanning Tree Protocol (STP) Administrative Mode for the
port or LAG. The possible values for this field are:
• Enable: Enables the Spanning Tree Protocol for this port.
• Disable: Disables the Spanning Tree Protocol for this port.
STP State Shows the port's current state Spanning Tree state. This state controls
what action a port takes on receipt of a frame. If the bridge detects a

the duplex mode and speed are set from the auto-negotiation process.
Physical Status Indicates the port speed and duplex mode status.
Link Status Indicates whether the Link is up or down.
