Table 7-1 Spanning Tree Configuration Menu Settings
Setting Description
Switch ID The identification number of the IntraSwitch. This
value cannot be changed.
STP Status The status of Spanning Tree on the IntraSwitch.
Enabled — Spanning Tree is enabled.
Disabled — Spanning Tree is disabled.
Switch
Priority
The priority value for this IntraSwitch switch.
The switch with the lowest priority value in a Spanning
Tree becomes the root bridge.
Maximum
Age
Determines how long the switch waits before trying to
re-configure the network when it is the Root Bridge.
If the switch has not received a BPDU within the time
specified, it will try to reconfigure the STP topology.
The default value is 20 seconds. The range of
permitted values is between 6 and 40 seconds.
Increasing the value of the Hello timer and the
Maximum Age timer together may reduce the amount
of traffic on a stable network. However, the bridge
processes information about changes to available
paths more slowly. As a result, when a change occurs,
it takes longer for the bridge to adjust.
Hello Time Controls the frequency at which the switch sends a
BPDU or “hello” packet.
The default value is 2 seconds. (This causes the switch
to broadcast a BPDU packet every two seconds.)
The range of permitted values is between 1 and 10
seconds.
Increasing the value of the Hello timer may reduce the
number of BPDU packets transmitted on the network
and may make the network less responsive to change.
