Configure the following parameters and click the Apply button to implement them:
Parameter Description
Spanning Tree
Protocol <Disabled>
This field can be toggled between Enabled and Disabled using the pull-down
menu. This will enable or disable the Spanning Tree Protocol (STP), globally,
for the Switch.
Bridge Max Age: (6 -
40 sec)
<20 >
The Max. Age can be set from 6 to 40 seconds. At the end of the Max. Age,
if a BPDU has still not been received from the Root Bridge, your Switch will
start sending its own BPDU to all other Switches for permission to become
the Root Bridge. If it turns out that your Switch has the lowest Bridge
Identifier, it will become the Root Bridge.
Bridge Hello Time: (1
- 10 sec) < 2 >
The Hello Time can be set from 1 to 10 seconds. This is the interval between
two transmissions of BPDU packets sent by the Root Bridge to tell all other
Switches that it is indeed the Root Bridge.
