GS748T Smart Switch Software Administration Manual Field Description Port Forwarding State Indicates the current STP state of a port. If enabled, the port state determines what forwarding action is taken on traffic. Possible port states are: • Disabled: STP is currently disabled on the port. The port forwards traffic while learning MAC addresses. • Blocking: The port is currently blocked and cannot be used to forward traffic or learn MAC addresses. • Listening: The port is currently in the listening mode. The port cannot forward traffic nor can it learn MAC addresses. • Learning: The port is currently in the learning mode. The port cannot forward traffic, however, it can learn new MAC addresses. • Forwarding: The port is currently in the forwarding mode. The port can forward traffic and learn new MAC addresses Port Role Each MST Bridge Port that is enabled is assigned a Port Role for each spanning tree. The port role will be one of the following values: Root Port, Designated Port, Alternate Port, Backup Port, Master Port, or Disabled Port. Designated Root Root Bridge for the selected MST instance. It is made up using the bridge priority and the base MAC address of the bridge. Designated Cost Displays cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops. Designated Bridge Bridge Identifier of the bridge with the Designated Port. It is made up using the bridge priority and the base MAC address of the bridge. Designated Port Port Identifier on the Designated Bridge that offers the lowest cost to the LAN. It is made up from the port priority and the interface number of the port. Click Refresh to update the screen with the latest MST information. STP Statistics Use the Spanning Tree Statistics page to view information about the number and type of bridge protocol data units (BPDUs) transmitted and received on each port.
