policy qos name <policy-name> shaper profile <profile-name> queue <queue-id> wred-map filter-weight <weight>

Controls the rate at which the average queue length tracks the actual/current queue length, for the particular context that you specify in this configuration path.

policy
This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.
qos
This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.
name <policy-name>
Specifies the name of a QoS policy.
shaper
This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.
profile <profile-name>

The name of a QoS profile.

In policy qos name <policy-name> shaper profile <profile-name>, the profile name is always a local QoS profile. Configurations paths that have this root define a local QoS profile.

In policy qos name <policy-name> shaper default <profile-name> or policy qos name <policy-name> shaper class <class-number> profile <profile-name> the profile name can be either a local or global QoS profile name. A configuration path that has either of these roots references a QoS profile that is defined either locally or globally.

queue <queue-id>
Specifies the profile queue identifier.
wred-map
This keyword exists for 'organizational' purposes only, to structure the configuration path for relevant command strings.
filter-weight <weight>

The exponentially weighted moving average (EWMA) filter weight value. The default value is 9.

This value controls how quickly or slowly the WRED algorithm's average queue length tracks the queue actual queue length.

  • With a low filter-weight <weight> value, the computed average queue length will track the actual queue length quickly.
  • With a high filter-weight <weight> value, the computed average queue length will track the actual queue length slowly.
