This is the lowest level of the scheduling hierarchy. It defines how much of the parent profile's bandwidth the traffic class will use.

If you do not configure this then the traffic class is able to use up to 100% of the parent profile's bandwidth.

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.

traffic-class <tc-id>

Specifies a traffic class identifier.

bandwidth <limit>

The maximum bandwidth. Vyatta uses a 'maximum bandwidth' model of QoS, rather than a 'guaranteed bandwidth' model.

Depending on your QoS configuration, you can set a maximum bandwidth limit for a shaper, profile or traffic class.

• To define the limit with the default units of kilobits per second, you may use a number only.
• To define the limit with other units, use a number plus a suffix. No space. For example: 10mbit; 40%.

Vyatta NOS supports these suffixes:

• No suffix: Kilobits (1000 bits) per second
• gbit: Gigabits (1000 megabits) per second
• gbps: Gigabytes (1000 megabytes) per second
• gi: Gibibits (1024 mebibits) per second
• kbit: Kilobits (1000 bits) per second
• kbps: Kilobytes (1000 bytes) per second
• ki: Kibibits (1024 bits) per second
• mbit: Megabits (1000 kilobits) per second
• mbps: Megabytes (1000 kilobytes) per second
• mi: Mebibits (1024 kibibits) per second
• %: Percentage of the total bandwidth
