shaper outbound

Description

Use shaper outboundcommand to shape individual WAN, LAN, or management interfaces, or to shape the aggregate WAN interface.

Use the no command to remove an outbound shaper.

Syntax

shaper outbound <shaper name> {enable | disable}

shaper outbound <shaper name> accuracy <usec>

shaper outbound <shaper name> max-bandwidth <kbps>

shaper outbound <shaper name> traffic-class <1-10> excess-weight <weight>

shaper outbound <shaper name> traffic-class <1-10> max-bandwidth <% of interface bandwidth>

shaper outbound <shaper name> traffic-class <1-10> max-wait <ms>

shaper outbound <shaper name> traffic-class <1-10> min-bandwidth <% of interface bandwidth>

shaper outbound <shaper name> traffic-class <1-10> priority <1-10>

no shaper outbound {<shaper name> | default | wan}

Arguments

disable	Disables outbound shaper.
enable	Enables outbound shaper.
<shaper name>	Refers to the shaper for a specific interface, such as wan0, wan1, twan0, twan1, bwan0, lan0, lan1, tlan0, tlan1, blan0, mgmt0, mgmt1. Use wan for shaping the aggregate WAN interface. Availability of the non-WAN interfaces (as arguments) is to facilitate preparations for migrating from one appliance model to another, or one deployment mode to another.
accuracy <usec>	Specifies shaper accuracy in microseconds.
traffic-class <1-10>	Specifies the shaper traffic class.
excess-weight <weight>	Specifies the shaper traffic class excess weight. If there is remaining bandwidth after satisfying the minimum bandwidth, then the excess is distributed among the traffic classes in proportion to the weightings specified . Values range from 1 to 10,000.
max-bandwidth <% of interface bandwidth>	Specifies the traffic class’s maximum bandwidth in kilobits per second. You can limit the maximum bandwidth that a traffic class will use by specifying a percentage. The bandwidth usage for the traffic class never exceeds this value.
max-wait <ms>	Specifies the maximum wait time in milliseconds. Any packets waiting longer than the specified Max Wait Time are dropped.
min-bandwidth <% of interface bandwidth>	Specifies the shaper’s minimum bandwidth in kilobits per second. Each traffic class is guaranteed this percentage of bandwidth, allocated in the order of priority. However, if the sum of the percentages is greater than 100%, then lower-priority traffic classes might not receive their guaranteed bandwidth if it is all consumed by higher-priority traffic.
priority <1-10>	Specifies the shaper traffic class priority. This determines the order in which each class's minimum bandwidth is allocated - 1 is first, 10 is last.

Defaults

None.

Usage Guidelines

The Shaper provides a simplified way to globally configure QoS (Quality of Service) on the appliances.

n	It shapes outbound traffic by allocating bandwidth as a percentage of the system bandwidth.

n	The system applies these QoS settings globally after compressing (deduplicating) all the outbound tunnelized and pass-through-shaped traffic --- shaping it as it exits to the WAN.

n	Availability of the non-WAN interfaces (as arguments) is to facilitate preparations for migrating from one appliance model to another, or one deployment mode to another.

Examples
