To configure Spanning Tree Protocol functions for the Switch or individual ports, enter the desired information in the fields
on this window (see the descriptions below for assistance) and then click Apply.
The information on the window is described as follows:
♦ Spanning Tree Protocol (STP) for all ports is This option offers Disabled or Enabled to implement
the Spanning Tree Protocol.
♦ Bridge Priority: (0 .. 65535)/Priority A Bridge Priority can be from 0 to 65535. Zero is equal to the highest
Bridge Priority.
♦ Hello Time: (1 . . 10 sec) The Hello Time can be 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. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if
and when your Switch becomes the Root Bridge.
♦ Forward Delay: (4 . . 30 sec) The Forward Delay can be from 4 to 30 seconds. This is the time any port on
the Switch spends in the listening state while moving from the blocking state to the forwarding state.
♦ Maximum Age: (6 . . 40 sec) The Maximum Age can be from 6 to 40 seconds. At the end of the Maximum
Age, if a BPDU has still not been received from the Root ridge, 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.
