Parameter
Description
Ethernet Edge Port
Select this check box to enable the Ethernet Edge Port function
(recommended) when no RSTP device is connected to the Ethernet port.
This allows immediate communication through the Ethernet port.
Because RSTP is an active protocol, it depends on communication
between RSTP devices. If no RSTP device is connected to the radio’s
Ethernet port, the handshake cannot take place. In this case, RSTP
reverts to STP. This means that the Ethernet port is forced to adhere to
the timer based transition protocol of STP.
Therefore on network transitions and power up, communications are not
allowed over the Ethernet port for 30 to 45 seconds unless you enable
E
THERNET
E
DGE
P
ORT
. This setting specifies that no redundant
connections exist out the Ethernet port and communication can start
immediately. If for some reason the radio receives a BPDU (bridge
protocol data unit) on this port, the RSTP protocol negotiates properly
and handles any possible redundant paths.

Bridge Times
Configures the timing intervals to use.
Priority
Determines which device is the root of the RSTP. The RSTP device with
the lowest priority becomes the root bridge.
The accepted standard value for this is
32768
. If wired switches
exist in the network that support RSTP, they should always be
allowed to be the root.
For Master radios, set this value to
32769
to prevent the radio from
being the root over a wired switch.
For Repeater radios, set this value to
32770
. This specifies that if
the network only has RLX2-IHx series radios, the Master radio
becomes the root.
Hello Time
Specifies the rate at which the radio sends out BPDUs. The
recommended industry standard is 2 seconds.
Max Age
Specifies the age limit for protocol information for a port.
The radio measures the age of the received protocol information
recorded for a port and discards it when the information's age limit
exceeds this value. The timeout value for this timer is the maximum age
parameter of the root.
Forward Delay
Specifies the timeout for time spent by a port in the learning and listening
states. The timeout value is the forward delay parameter of the root.
Path Costs
RSTP and STP algorithms use a cost to determine which connections
should be used in the Spanning Tree. The radio forms the Spanning
Tree by determining the lowest cost paths from any RSTP device back
to the root.
Wireless
Gives preference to a wired connection, set the Wireless cost to
200
.
Ethernet
Gives preference to a wired Ethernet connection, set the Ethernet cost to
100
.
