Communication Redundancy STP/RSTP/MSTP
4-7
At the top of this page, the user can check the Current Status of this function. For RSTP, you will see:
Now Active:
It shows which communication protocol is being used—Turbo Ring, RSTP, or neither.
Root/Not Root
This field only appears when RSTP mode is selected. The field indicates whether or not this switch is the Root
of the Spanning Tree (the root is determined automatically).
At the bottom of this page, the user can configure the Settings of this function. For RSTP, you can configure:
Redundancy Protocol
Setting
Description
Factory Default
Turbo Ring
Select this item to change to the Turbo Ring configuration page.
None
RSTP (IEEE
802.1W/1D)
Select this item to change to the RSTP configuration page.
None
Bridge priority
Setting
Description
Factory Default
Numerical value
selected by user
Increase this device’s bridge priority by selecting a lower
number. A device with a higher bridge priority has a greater
chance of being established as the root of the Spanning Tree
topology.
32768
Forwarding Delay (sec.)
Setting
Description
Factory Default
Numerical value input
by user
The amount of time this device waits before checking to see if it
should change to a different state.
15
Hello time (sec.)
Setting
Description
Factory Default
Numerical value input
by user
The root of the Spanning Tree topology periodically sends out a
“hello” message to other devices on the network to check if the
topology is healthy. The “hello time” is the amount of time the
root waits between sending hello messages.
2
Max. Age (sec.)
Setting
Description
Factory Default
Numerical value input
by user
If this device is not the root, and it has not received a hello
message from the root in an amount of time equal to “Max.
Age,” then this device will reconfigure itself as a root. Once two
or more devices on the network are recognized as a root, the
devices will renegotiate to set up a new Spanning Tree
topology.
20
Enable STP per Port
Setting
Description
Factory Default
Enable/Disable
Select to enable the port as a node on the Spanning Tree
topology.
Disabled
NOTE
We suggest not enabling the Spanning Tree Protocol once the port is connected to a device (PLC, RTU, etc.) as
opposed to network equipment. The reason is that it will cause unnecessary negotiation.
