RSTP Settings (for AP/Master/ACC mode only)
AWK-3131A-M12-RCC supports IEEE802.1D Spanning Tree Protocol and IEEE802.1w Rapid STP standards. In
addition to eliminating unexpected path looping, STP/RSTP can provide a backup path recovery if a wired/
wireless path fails accidentally. The reliability and availability can increase because this fail-over function.
AWK-3131A-M12-RCC’s STP/RSTP feature is disabled by default. To be completely effective, you must enable
RSTP/STP on every AWK-3131A-M12-RCC connected to your network. If AWK-3131A-M12-RCC plays a Client
role, which is connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not
necessary to enable STP/RSTP. The reason is that it will cause unnecessary negotiation.
AWK-3131A-M12-RCCs support STP/RSTP in AP mode only.
The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed
explanation of each parameter is given below the figure.
RSTP status
This field will appear only when selected to operate STP/RSTP. It indicates whether this AWK-3131A-M12-RCC
is the Root of the Spanning Tree (the root is determined automatically) or not.
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)
ATTENTION
Be careful when you enable the filter function:
Drop + “
no
entity on list is activated” = all packets are allowed
Accept + “
no
entity on list is activated” = all packets are denied
