Field Description
Bridge Times Configures the timing intervals to use.
Priority Determines who should be the root of the RSTP. The RSTP device with the
lowest priority becomes the root. 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.
Set this value to 32769 to prevent the radio from being the root over a wired
switch. Use this setting when a radio is configured to be a Master.
Set this value to 32770 when the radio is configured to be a Repeater. In this
way, if only RLX2 radios exist in the network, the Master radio will become
the root.
Hello Time Rate at which BPDUs are sent out. The industry standard is 2 seconds.
Max Age Measures the age of the received protocol information recorded for a port
and ensures this information is discarded when its age limit exceeds the
value to the maximum age parameter recorded by the switch. The timeout
value for this timer is the maximum age parameter of the switches.
Forward Delay Monitors the time spent by a port in the learning and listening states. The
timeout value is the forward delay parameter of the switches.
Path Costs RSTP and STP algorithms use a cost to determine which connections should
be used. The "spanning tree" is formed by determining the least 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.
Multiple master radios can be defined on the same network. If one master radio goes
down, any radios linked to it can switch over to the other master, so the networked
radios remain connected and transmitting. In order to be redundant, the two masters
should typically be on the same segment—in other words, they should be wired
together into the same switch. These two masters can be assigned different channels to
increase network bandwidth, but they must be assigned the same SSID.
Also, because all radios are repeaters, each radio can be configured to reach a master
radio via multiple repeater paths. If a repeater goes down, the linked radios can use a
different path to get back to a master radio.
