The overall bandwidth that is set for the parent policy determines the maximum bandwidth that all child profiles under that policy may use. This bandwidth command controls the maximum amount of bandwidth that this profile will use as a portion of the parent policy's overall bandwidth.

If you do not configure a shaper profile <profile-name> bandwidth <limit> command then the child profile will be able to use up to 100% of the parent policy's bandwidth. Note that this profile bandwidth is the parent to this profile's four traffic class bandwidth commands.

policy

qos

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.

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
