Stp Switch Settings - D-Link DGS-3224TGR - Switch User Manual

STP Switch Settings

The switch supports 802.1W Rapid Spanning Tree Protocol, which allows you to create alternative paths (with multiple
switches or other types of bridges) in your network. See the Spanning Tree Algorithm section of the "Switch Management
and Operating Concepts" chapter for a detailed explanation.
Click Apply after making changes to the window above.
The STP Switch parameters that you can change are:
Parameter
Status
Max Age (6-40 sec) <20>
Hello Time (1-10 sec) <2>
Forward Delay (4-30 sec)
<15>

Description
This drop-down menu allows you to enable the Spanning Tree Protocol setting.
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 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.
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.
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.
