Description
Configures WRED on the specified QoS profile for the specified port.
Syntax Description
|
egress
|
This optional parameter
specifies an egress QoS profile. |
|
qosprofile
|
Specifies a QoS profile name.
Valid names are QP1 to QP8. Note: On Summit X670 and BlackDiamond X8 switches, QoS profiles QP5
to QP8 do not support WRED.
|
|
color
|
Specifies the WRED color to be configured.
Valid colors for BlackDiamond 8900 c- and
xl-series modules, E4G-200 and E4G-400 switches, and Summit X460
and X480 switches are: TCP green, TCP red, and non-TCP any.
Valid colors for BlackDiamond X8 series
switches, BlackDiamond 8900-40G6X-xm modules and Summit X670
switches are: TCP green, TCP red, non-TCP any, and non-TCP
red.
|
|
green
|
Specifies that the WRED
configuration applies to TCP traffic that is marked green. |
|
non-tcp any
|
Specifies that the WRED
configuration applies to any non-TCP traffic. |
|
red
|
Specifies that the WRED
configuration applies to TCP traffic that is marked red. |
|
min_thresh
|
Specifies the minimum
threshold for the specified WRED color. The range is 1 to 100
percent. |
|
max_threshold
|
Specifies the maximum
threshold for the specified WRED color. The range is 1 to 100
percent. |
|
max_drop_rate
|
Specifies the maximum drop
rate for the specified WRED color. The range is 1 to 100
percent. |
|
port_list
|
Specifies a list of slots and
ports to which the parameters apply. Specify ports in the following
formats: 3-5, 2:5, 2:6-2:8. |
|
non-tcp
red
|
Specifies that the WRED
configuration applies to non-TCP traffic that is marked red. |
|
avg_weight
|
Specifies the weight constant
for calculating the average queue size for the specified QoS
profile. The range is 1 to 15. |
|
all
|
Specifies that this command
applies to all ports on the device. |
|
Default
- Minimum threshold—100%
- Maximum threshold—100%
- Maximum drop rate—100%
- Average weight—4
Usage Guidelines
The max_drop_rate, min_threshold, and max_threshold
parameters apply to the specified color. The avg_weight
parameter
applies to all colors on the specified QoS profile. Increasing the avg_weight value
reduces the probability that traffic is dropped. Conversely, decreasing the
avg_weight value increases the probability that traffic is dropped.
Example
The following example configures WRED settings for port 2:1, QoS
profile qp3, color green:
configure qosprofile qp3 wred color tcp green min-threshold 80 max-threshold 95 max-drop-rate 75 ports 2:1
The following example configures the average weight for port 2:1,
QoS profile qp2:
configure qosprofile qp2 wred avg-weight 4 ports 2:1
The following example configures WRED settings for non-TCP traffic
on port 4, QoS profile qp3:
configure qosprofile qp3 wred color non-tcp any min-threshold 10 ports 4
The following example configures WRED settings using
"wredGroup" as the port_group variable:
configure qosprofile qp8 wred color tcp red min-threshold 25 max-streshold 75 max-drop-rate 30 ports wredGroup
History
This command was
first available in ExtremeXOS 12.7.
The port_group variable was added in ExtremeXOS 16.1.
Platform Availability
This command is available on BlackDiamond X8 series switches,
BlackDiamond 8900 c-, xl-, and xm-series modules, E4G-200 and E4G-400 switches, and
Summit X460, X460-G2, X480, X670, X670-G2, and X770 switches.
