Configuring STP/RSTP
The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed
explanation of each parameter follows.
At the top of this page, the user can check the “Current Status” of this function. For RSTP, you will see:
Now Active:
This will show which communication protocol is being used—Turbo Ring, RSTP, or neither.
Root/Not Root
This field will appear only when selected to operate in RSTP mode. It indicates whether or not this EDS-P510 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:
Protocol of Redundancy
Setting Description Factory Default
Turbo Ring Select this item to change to the Turbo Ring configuration
page.
Turbo Ring V2 Select this item to change to the Turbo Ring V2
configuration page.
Turbo Chain Select this item to change to the Turbo Chain configuration
page.

None Ring redundancy is not active
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.

Forwarding Delay
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 (sec.)
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.
