Configuring Rate-Limit Actions (SRC CLI)

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 ;
color-aware;
support-hierarchical;
description description ;
}

To configure a rate-limit action:

  1. From configuration mode, enter the rate-limit action configuration. For example, in this procedure, rla is the name of the rate-limit action.
    user@host# edit policies group junose list rate-limiter rule pr rate-limit rla
  2. (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.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set type type
  3. (Optional) Configure the target rate for the traffic that the policy covers.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set committed-rate committed-rate
  4. (Optional) Configure the amount of bandwidth allocated to burst traffic in bytes.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set committed-burst committed-burst
  5. (Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to excess traffic flow over the committed rate.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set peak-rate peak-rate
  6. (Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to burst traffic in excess of the peak rate.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set peak-burst peak-burst
  7. (Optional) For one-rate rate-limit profiles, specify the amount of bandwidth allocated to accommodate burst traffic.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set excess-burst excess-burst
  8. (Optional) Set the rate limit to color aware for the rate-limit to process color values.
    [edit policies group parentGroupDefault list twoRate parent-group PGShared]
    user@host# set color-aware
  9. (Optional) Set the rate limit to support hierarchical rate limits.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set support-hierarchical
  10. (Optional) Configure the rate-limit action for traffic flows that:
  11. (Optional) Enter a description for the rate-limit action.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
    user@host# set description description
  12. (Optional) Return to the rate-limit action configuration, and verify the configuration.
    [edit policies group junose list rate-limiter rule pr rate-limit rla]
user@host# show 
committed-action { 
  forward {
  }
}
conformed-action {
  forward {
  }
}
exceed-action {
  filter {
  }
}
type 1;
committed-rate 1000000;
committed-burst 125000;
excess-burst 312500;
