AirWorks AWK-3121 User’s Manual
Web Console Configuration
3-32
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)
The AWK-3121 comes with 10 “ports” for RSTP settings. Numbers 3-10 (WDS1-WDS8) are
available only when WDS is enabled in AP mode.
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
2000000
Edge port
Setting
Description
Factory Default
Checked/ unchecked
Sets a port, which no BPDU expectedly goes
through, as an edge port
unchecked, except
AP
port
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.
