policy qos profile <profile-name> queue <queue-id> wred-map dscp-group <dscp-group-name> min-threshold <min-threshold>

Controls the threshold of the average queue length at which the WRED algorithm will start to drop packets at random, 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.
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.
dscp-group <dscp-group-name>
Specifies the name of a DSCP group.
min-threshold <min-threshold>
Where <min-threshold> is { <min-threshold-bytes> | <min-threshold-pkts> | <min-threshold-time> }. The minimum threshold level value. To understand more about this, see WRED algorithm.
Note: Not all of the value types are available for all platforms. For example, the UfiSpace S9500-30XS supports { <min-threshold-bytes> | <min-threshold-time> } whilst most other platforms support only <min-threshold-pkts>.
  • <min-threshold-bytes>: The minimum threshold level, where we express the value as a number of bytes.
  • <min-threshold-pkts>: The minimum threshold level, where we express the value as a number of packets.
  • <min-threshold-time>: The minimum threshold level, where we express the value as a number of milliseconds.
