Configures WRED on the specified QoS profile for the specified port.
| egress | This optional parameter specifies an egress QoS profile. |
| qosprofile | Specifies a QoS profile name. Valid names are QP1 to QP8. |
| color |
Specifies the WRED color to be configured. |
| 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. |
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.
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
This command was first available in ExtremeXOS 12.7.
The port_group variable was added in ExtremeXOS 16.1.
This command is available on the ExtremeSwitching 5520 platform.
