Chapter 3 Using the console interface 161Using the BayStack 380 10/100/1000 SwitchForward Delay Indicates the Forward Delay parameter value that the root bridge is currently using. Thisvalue specifies the amount of time that the bridge ports remain in the Listening andLearning states before entering the Forwarding state.Note that the root bridge’s Forward Delay parameter value becomes the actual ForwardDelay parameter value for all bridges participating in the spanning tree network. See alsoBridge Forward Delay.Default Value 15 secondsRange 4 to 30 secondsBridge HelloTimeIndicates the Hello Interval (the amount of time between transmissions of BPDUs)specified by management for this bridge. This parameter takes effect only when thisbridge becomes the root bridge.Note that, although you can set the Hello Interval for a bridge using bridge managementsoftware, once the spanning tree computation process is complete, all bridgesparticipating in the spanning tree network use the root bridge’s Hello Interval parametervalue. If any bridge becomes the root bridge, its Hello Interval parameter value becomesthe Actual Hello Interval parameter value for all bridges participating in the spanning treenetwork. See also Hello Time.Default Value 2 secondsRange 1 to 10 secondsBridgeMaximum AgeTimeSpecifies the maximum age (in seconds) that a Hello message can attain before it isdiscarded. This parameter, specified by management for this bridge, takes effect onlywhen the bridge becomes the root bridge.Note that, if this bridge becomes the root bridge, its Maximum Age Time parameter valuebecomes the Actual Maximum Age Time parameter value for all bridges participating inthe spanning tree network. See also Maximum Age Time.Default Value 20 secondsRange 6 to 40 secondsBridge ForwardDelayIndicates the Forward Delay parameter value specified by management for this bridge.This parameter takes effect only when this bridge becomes the root bridge.The Forward Delay parameter value specifies the amount of time that the bridge portsremain in the Listening and Learning states before entering the Forwarding state.Note that all bridges participating in the spanning tree network use the root bridge’sForward Delay parameter value.
