Quidway S8500 Series Routing Switches Chapter 4 RPR Port Configuration Commands

value: Node weight. The default value is 1.
Description
Use the rpr weight command to configure the node weight. Fairness algorithm uses
node weight to calculate local fairness rate. The default weight is 1.
Use the undo rpr weight command to restore the default weight.
The fairness algorithm calculates the local fairness rate based on the node weight
value. By default, the weight value is 0. In fact, the weight value configured here is the
N
th
power of 2, namely weight = 2
value
, where value ranges 0 to 7. Therefore, the value
range of weight is 1 to 255.
Example
# Set weight of nodes on ringlet0 to 2.
<Quidway> system-view
[Quidway] interface RPR2/1/1
[Quidway-RPR2/1/1] rpr weight ringlet0 2
4.1.26 sdh threshold
Syntax
sdh threshold {sd-ber value | sf-ber value }
undo sdh threshold { sd-ber | s-ber }
View
RPR POS physical port view
Parameter
sd-ber: Threshold for signal degrade (SD BER).
sf-ber: Threshold for signal failure (SF BER).
value: Threshold index, in the range of 3 to 9. That is the alarm threshold is 10e
-
value.
Description
Use the sdh threshold command to configure the thresholds for SD and SF. By default,
SD BER is 6, and SF BER is 3.
Use the undo sdh threshold command to restore the default configuration.
The alarm information configured by this command is the overhead in SDH frame
header, which monitors SDH signals at each layer.
Example
# Set SD threshold for RPR POS physical port to 10e-6.
