Example usage
To configure sred:
DES-3528:admin# config sred all all threshold low 64 high 80 drop_rate low 8 high 8
drop_green disable
Command: config sred all all threshold low 64 high 80 drop_rate low 8 high 8
drop_green disable
Success.
Used to config the simple RED paremeter.
config sred [<portlist> | all] [<class_id 0-7> | all] { threshold {low <value 0-100> |
high<value 0-100>}(1) | drop_rate {low<value 1-8> | high<value 1-8>}(1) | drop_green
[enable | disable]}(1)
This command is used to onfigure sRED threshold per port or per port per queue.
portlist − A range of ports to config.
class_id − This specifies which of the 8 hardware CoS queues the config sred command will
apply to.
all – Specifies that all the ports will be used for this configuration.
threshold − See below:
low - Specifies the low threshold that the percent of space utilized. By default, the value is
60. The range is 0 to 100.
high – Specifies the high threshold that the percent of queue space utilized. By default, the
value is 80. The range is 0 to 100.
drop_rate – See below:
low − Specifies the probabilistic drop rate if above the low threshold. By default, the value is
1.
high − Specifies the probabilistic drop rate if above the high threshold. By default, the value is
1.
drop_green – See below:
disable − Specifies the probabilistic drop red colored packets if the queue depth is above the
low threshold, and probabilistic drop yellow colored packets if the queue depth is above the
high threshold. By default, if the option is not specified, the setting is disable.
enable − Specifies the probabilistic drop yellow and red colored packets if the queue depth is
above the low threshold, and probabilistic drop green colored packets if the queue depth is
above the high threshold.
Only Administrator and Operator and Power-User-level users can issue this command.
NOTE: There are 8 drop rates:
1 100%
2 6.25%
3 3.125%
4 1.5625%
5 0.78125%
6 0.390625%
7 0.1953125%
8 0.09765625%
