Forward Delay:You can set the root bridge forward delay time. This figure is set by rootbridge only. The forward delay time is defined as the time spent fromListening state moved to Learning state and also from Learning statemoved to Forwarding state of a port in bridge. The forward delay timecontains two states, Listening state to Learning state and Learning stateto Forwarding state. It assumes that forward delay time is 15 seconds,then total forward delay time will be 30 seconds. This has much to dowith the STP convergent time which will be more than 30 secondsbecause some other factors.The valid value is 4 ~ 30 seconds, default is 15 seconds.Force Version:Two options are offered for the user’s choosing STP algorithm. One isRSTP and the other is STP. If STP is chosen, RSTP will run as a legacySTP. The switch supports RSTP (802.1w) which is backward compatiblewith STP (802.1d).Fig. 3-47108
3-13-3. STP Port ConfigurationFunction name:STP Port SettingFunction description:In the STP Port Setting, one item selection and five parameters settings areoffered for user’s setup. User can disable and enable each port by selectingeach Port Status item. User also can set “Path Cost” and “Priority” of each portby filling in the desired value and set “Admin Edge Port” and “Admin Point ToPoint” by selecting the desired item.Parameter description:Port Status:It displays the current state of a port. We cannot manually set it becauseit displays the status only. There are three possible states. ( according to802.1w specification)• DISCARDING state indicates that this port can neither forward packetsnor contribute learning knowledge.Notice: Three other states (Disable state, BLOCKING state and LISTENINGstate) defined in the 802.1d specification are now all represented asDISCARDING state.• LEARNING state indicates this port can now contribute its learningknowledge but cannot forward packets still.• FORWARDING state indicates this port can both contribute its learningknowledge and forward packets normally.Path Cost Status:It is the contribution value of the path through this port to Root Bridge.STP algorithm determines a best path to Root Bridge by calculating thesum of path cost contributed by all ports on this path. A port with asmaller path cost value would become the Root Port more possibly.Configured Path Cost:The range is 0 – 200,000,000. In the switch, if path cost is set to be zero,the STP will get the recommended value resulted from auto-negotiationof the link accordingly and display this value in the field of Path CostStatus. Otherwise, it may show the value that the administrator set up inConfigured Path Cost and Path Cost Status.109
