Using the BayStack Model 350T 10/100 Autosense Switch
3-40 893-00992-A
Forward Delay: Indicates the Forward Delay parameter value, currently in use by the root bridge, that
specifies the length of time that the bridge ports remain in the Listening and Learning
states before entering the Forwarding state.
Note that the root bridge’s Forward Delay parameter value becomes the (actual) Forward
Delay parameter value for all bridges participating in the spanning tree network (see also
“Bridge Forward Delay” parameter).
Default Value: 15
Range: 4 to 30 seconds
Bridge Hello
Time:
Indicates the Hello interval (the amount of time between transmissions of Configuration
Bridge PDUs) that is specified (set by management) for this bridge. This parameter takes
effect only when this bridge becomes the root bridge.
Note that, although you can set the Hello Interval for a bridge with bridge management
software, once the spanning tree computation process is complete, all bridges
participating in the spanning tree use the root bridge’s Hello Interval parameter value. If
any bridge becomes the root bridge, its Hello Interval parameter value becomes the
(actual) Hello Interval parameter value for all bridges in the spanning tree network (see
also “Hello Time” parameter).
Default Value: 2
Range: 1 to 10 seconds
Bridge
Maximum Age
Time:
Specifies the maximum age (in seconds) that a Hello message can attain before it is
discarded. This parameter, set for this bridge by management, takes effect only when this
bridge becomes the root bridge. Note that, if this bridge becomes the root bridge, its
Maximum Age Time parameter value becomes the (actual) Maximum Age Time
parameter value for all bridges in the spanning tree network (see also “Maximum Age
Time” parameter).
Default Value: 20
Range: 6 to 40 seconds
Bridge Forward
Delay:
Indicates the Forward Delay parameter value that is specified (set by management) for
this bridge.
This parameter takes effect only when this bridge becomes the root bridge.
The Forward Delay parameter value specifies the length of time that the bridge ports
remain 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’s
Forward Delay parameter value (see also “Forward Delay” parameter).
Default Value: 15
Range: 4 to 30 seconds
