AirWorks AWK-5222 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-5222 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.
