Topology Changes Counts
state changes that have occurred.
Last Topology Change
The elapsed time since the bridge
was initialized or reset, and the last topographic change
occurred. The time is displayed in a day hour minute
second format, for example, 2 days 5 hours 10 minutes
and 4 seconds.
Spanning Tree > Global STP
The Global STP screen contains global parameters for STP
on the Switch.

Global Setting
Spannng Tree State Select Enable or Dsable from the
drop-down menu to enable or disable STP on the Switch.
The default is Enable.
BPDU Handlng
Determines how BPDU packets are
managed when STP is disabled on the port or Switch.
BPDUs are used to transmit spanning tree information.
The possible values are:
Flterng Filters BPDU packets when spanning tree is
•
disabled on an interface.
Floodng Floods BPDU packets when spanning tree is
•
disabled on an interface. This is the default value.
Path Cost Default Values
default path costs to STP ports. The possible values are:
Short Specifies a range of 1-65.535 for port path
•
costs.
Long
Specifies a range of 1-200.000.000 for port path
•
costs. The default path costs assigned to an interface

Bridge Settings
Prorty Specifies the bridge priority value. When
switches or bridges are running STP, each is assigned a
priority. After exchanging BPDUs, the device with the
lowest priority value becomes the Root Bridge. The default
value is 28. The value must be a multiple of 4096. For
example, 4096, 8192, 12288, etc. The range is 0 to .
Hello Tme Specifies the device Hello Time (the amount of
time in seconds a root bridge waits between configuration
messages). The default is 2 seconds. The range is 1 to 10
seconds.
Max Age Specifies the device Maximum Age Time (the
amount of time in seconds that a bridge waits before
sending configuration messages). The default is 20
seconds. The range is  to 40 seconds.
Forward Delay Specifies the device forward delay time
(the amount of time in seconds a bridge remains in a
listening and learning state before forwarding packets).
The default is 1 seconds. The range is 4 to 0 seconds.
Choose settings for the Hello Time, Max Age, and Forward
Delay parameters so that both of the following are true:
Max Age ≥ 2 × (Hello Time + 1)
2 × (Forward Delay – 1) ≥ Max Age
Click Save Settngs to save the changes, or Cancel
