3-29
Bridge priority
Setting
Description
Factory Default
Numerical value
selected
by user
You can increase the bridge priority by selecting a lower
number. A higher bridge priority brings a greater chance of
being established as the root of the Spanning Tree topology.
32768
Hello time
Setting
Description
Factory Default
Numerical value input
by user
(1 – 10 seconds)
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. Hello time indicates how often the root
sends hello messages.
2 (seconds)
Forwarding delay
Setting
Description
Factory Default
Numerical value input
by user
(4 – 30 seconds)
The amount of time this device waits before checking to see if it
should change to a different topology.
15 (seconds)
Max. age
Setting
Description
Factory Default
Numerical value input
by user
(6 – 40 seconds)
As a non-root role, if the device has not received a hello
message from the root longer than Max. age, it 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 (seconds)
Enable RSTP
Setting
Description
Factory Default
Enable/ disable
Enables or disables the port as a node on the Spanning Tree
topology.
Disable (unchecked)
Port priority
Setting
Description
Factory Default
Numerical value
selected by user
Increase this port’s priority as a node on the Spanning Tree
topology by inputting a lower number.
128
Port cost
Setting
Description
Factory Default
Enable/ Disable
Input a higher cost to indicate that this port is less suitable as a
node for the Spanning Tree topology
20000
Edge port
Setting
Description
Factory Default
Checked/ unchecked
Sets a port, which no BPDU expectedly goes through, as an
edge port
unchecked, except
WLAN1/2 ports
NOTE
We recommend you set an edge port for the port, which is connected to a non-STP/RSTP sub-network or an end
device (PLC, RTU, etc.) as opposed to network equipment. This can prevent unnecessary waiting and
negotiation of STP/RSTP protocol, and accelerate system initialization. When an edge port receives BPDUs, it
can still function as an STP/RSTP port and start negotiation.
Setting an edge port is different from disabling STP/RSTP on a port. If you disable STP/RSTP, a port will not deal
with STP/RSTP BPDUs at all.
