Maximum Age
Time For STP Group, indicates the Maximum Age Time parameter value that the root bridge is
currently using. This value specifies the maximum age that a Hello message can attain
before it is discarded.
Note that the root bridge’s Maximum Age Time parameter value becomes the actual
Maximum Age Time parameter value for all bridges participating in the spanning tree
network. See also Bridge Maximum Age Time.
Forward Delay For STP Group, 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 netw ork. See a lso
Bridge Forward Delay.
Bridge Hello
Time For STP Group, indicates the Hello Interval (the amount of time between transmissions
of BPDUs) 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 In terv al p aram et er va lue becomes
the Actual Hello Interval parameter value for all bridges participating in the span ning tre e
network. See also Hello Time.
Bridge
Maximum Age
Time
For STP Group, specifies the maximum age (in seconds) that a Hello message can attain
before it is discarded. This parameter, specified by management for this bridge, takes
effect only when the bridge becomes the root bridge.
Note that, if this bridge becomes the root bridge, its Maximum Age Time paramete r value
becomes the Actual Maximum Age Time parameter value for all bridges participating in
the spanning tree network. See also Maximum Age Time.
Bridge Forward
Delay For STP Group, indicates the Forward Delay parameter value specified by m ana gem en t
for this bridge. This parameter takes effect only when this bridge becomes the root
bridge.
