3-13. STP ConfigurationThe Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D)for avoiding loops in switched networks. When STP is enabled, ensure that onlyone path is active between any two nodes on the network at a time. User canenable Spanning Tree Protocol on switch’s web management and then set up otheradvanced items. We recommend that you enable STP on all switches to ensure asingle active path on the network.3-13-1. STP StatusFunction name:STP StatusFunction description:In the Spanning Tree Status, user can read 12 parameters to know STPcurrent status. The 12 parameters’ description is listed in the following table.Parameter description:STP State:Bridge ID:Show the current STP Enabled / Disabled status. Default is “Disabled”.Show switch’s bridge ID which stands for the MAC address of this switch.Bridge Priority:Show this switch’s current bridge priority setting. Default is 32768.Designated Root:Show root bridge ID of this network segment. If this switch is a rootbridge, the “Designated Root” will show this switch’s bridge ID.Designated Priority:Root Port:Show the current root bridge priority.Show port number connected to root bridge with the lowest path cost.Root Path Cost:Show the path cost between the root port and the designated port of theroot bridge.Current Max. Age:Show the current root bridge maximum age time. Maximum age time isused to monitor if STP topology needs to change. When a bridge doesnot receive a hello message from root bridge until the maximum age timeis counted down to 0, the bridge will treat the root bridge malfunctionedand issue a Topology Change Notification (TCN) BPDU to all otherbridges.105
