Configuring the WRED Profile
Configuring the WRED profile consists of enabling or disabling the administrative status of the profile for
a specific QSet instance. Consider the following when configuring the WRED profile status:
• WRED is supported only on the OmniSwitch 6900 and WRP 1 is the only profile supported.
Configuring additional profiles is not supported at this time
• The default WRP 1 profile parameters are not configurable and the profile cannot be deleted from the
switch configuration.
• The WRED profile status is applied to all the unicast queues associated with the QSet instance for the
port. Enabling or disabling WRED at the queue level is not supported.
• The queue threshold values applied are similar to configuring and applying bandwidth shaping rates to
limit bandwidth.
• The maximum queue threshold value applied determines the delay a packet may experience while
waiting for the queue to clear out other packets that arrived first.
By default, WRP 1 is disabled for each QSet instance. To enable the profile for the instance, use the qos
qsi wred command. For example:
-> qos qsi port 1/10 wred admin-state enable
-> qos qsi port 1/20-22 wred admin-state enable
-> qos qsi linkagg 5 wred admin-state enable
To verify the WRED profile configuration, use the show qos wrp command.
See the OmniSwitch AOS Release 8 CLI Reference Guide for more information about the qos qsi wred
and show qos wrp commands.
