Forward Delay
Indicates the Forward Delay parameter value that the root bridge is currently using. This 
value specifies the amount 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.
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) specified 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 using bridge management 
software, once the spanning tree computation process is complete, all bridges 
participating in the spanning tree network 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 participating in the spanning 
tree network. See also Hello Time.
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 participating in 
the spanning tree network. See also Maximum Age Time.
Default Value
20
Range
6 to 40 seconds
Bridge Forward 
Delay
Indicates 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 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.
Default Value
15
Range
4 to 30 seconds
