Configuring Rate-Limit Actions

Use this action to define the quality of service. You can configure rate-limit actions for JUNOSe policy rules.

The type of action that you can create depends on the type of policy rule. See Policy Information Model.

Use the following configuration statements to configure rate-limit actions:



policies group  name  list  name  rule  name  rate-limit  name  {
type  type ; 
committed-rate  committed-rate ; 
committed-burst  committed-burst ; 
peak-rate  peak-rate ; 
peak-burst  peak-burst ;
excess-burst  excess-burst ; 
description  description ; 
}
policies group  name  list  name  rule  name  rate-limit  name  committed-action  mark  mark-info {
value  value ; 
mask  mask ; 
}
policies group  name  list  name  rule  name  rate-limit  name  committed-action
parameter {
action  action ; 
}
policies group  name  list  name  rule  name  rate-limit  name  conformed-action
mark mark-info {
value  value ; 
mask  mask ; 
}
policies group  name  list  name  rule  name  rate-limit  name  conformed-action
parameter {
action  action ; 
}
policies group  name  list  name  rule  name  rate-limit  name  exceed-action  mark  mark-info {
value  value ; 
mask  mask ; 
}
policies group  name  list  name  rule  name  rate-limit  name  exceed-action
parameter {
action  action ; 
}

To configure a rate-limit action:

From configuration mode, enter the rate-limit action configuration. For example, in this procedure, rla is the name of the rate-limit action.
(Optional) Specify that the rate-limit profile is either one rate or two rate. The rate-limit type determines the options that you can configure for a rate-limit action.
(Optional) Configure the target rate for the traffic that the policy covers.
(Optional) Configure the amount of bandwidth allocated to burst traffic in bytes.
(Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to excess traffic flow over the committed rate.
(Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to burst traffic in excess of the peak rate.
(Optional) For one-rate rate-limit profiles, specify the amount of bandwidth allocated to accommodate burst traffic.
(Optional) Enter a description for the rate-limit action.
(Optional) Configure the rate-limit action for traffic flows that do not exceed the committed rate to one of the following:
- Filter.
- Forward.
- Mark. If you select mark, enter the mark values.
- Parameter. Before you assign a parameter, you must create a parameter of type packetOperation and commit the parameter configuration.
(Optional) Configure the rate-limit action for traffic flows that exceed the committed rate but remain below the peak rate to one of the following:
- Filter.
- Forward.
- Mark. If you select mark, enter the mark values.
- Parameter. Before you assign a parameter, you must create a parameter of type packetOperation and commit the parameter configuration.
(Optional) Configure the rate-limit action for traffic flows that exceed the peak rate to one of the following:
- Filter.
- Forward.
- Mark. If you select mark, enter the mark values.
- Parameter. Before you assign a parameter, you must create a parameter of type packetOperation and commit the parameter configuration.

(Optional) Return to the rate-limit action configuration, and verify the configuration.
