Configuring Hierarchical Rate-Limit Actions (SRC CLI)

You configure parent groups to create a hierarchy of rate limits.

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 parent-group name {
               description description;
               }
               
               policies group name list name parent-group name parent-group
                  name {
               
               description description;
               }
               
               policies group name list name parent-group name rate-limit
                  {
               
               type type;
               committed-rate committed-rate;
               committed-burst committed-burst;
               peak-rate peak-rate;
               peak-burst peak-burst;
               excess-burst excess-burst;
               color-aware;
               }

To configure a parent group:

From configuration mode, create a parent group in a policy list; for example, PGShared.


                  
                     [edit policies group parentGroupDefault list twoRate]
                     user@host# edit parent-group PGShared

Configure a rate limit for the parent group.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared]
                     
                     user@host# edit rate-limit rate-limit

Specify that the rate-limit 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 parentGroupDefault list twoRate parent-group
                        PGShared rate-limit]
                     
                     user@host# set type  type

(Optional) Configure the target rate for the traffic that the policy covers.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared rate-limit]
                     
                     user@host# set committed-rate  committed-rate

(Optional) Configure the amount of bandwidth allocated to burst traffic in bytes.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared rate-limit]
                     
                     user@host# set committed-burst  committed-burst

(Optional) For two-rate rate-limit profiles, specify the amount of bandwidth allocated to excess traffic flow over the committed rate.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared rate-limit]
                     
                     user@host# set peak-rate  peak-rate

(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 parentGroupDefault list twoRate parent-group
                        PGShared rate-limit]
                     
                     user@host# set peak-burst  peak-burst

(Optional) For one-rate rate-limit profiles, specify the amount of bandwidth allocated to accommodate burst traffic.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared]
                     
                     user@host# set excess-burst  excess-burst

(Optional) Set the rate limit to color aware for the rate-limit to process color values set in the TOS byte of the packet header.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared]
                     
                     user@host# set color-aware

(Optional) Configure the rate-limit actions for traffic flows that:

Do not exceed the committed rate and burst size
Exceed the committed rate but remains below the peak burst size
Exceed the committed rate but remains below the peak burst size

See Configuring Types of Actions for Rate-Limit Actions (SRC CLI).

Enter a description for the parent group.


                  
                     [edit policies group parentGroupDefault list twoRate parent-group
                        PGShared]
                     
                     user@host# set description description

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

[edit policies group parentGroupDefault list twoRate parent-group PGShared]
user@host# show

(Optional) Create another parent group within this parent group. For example:


                  
                     [edit policies group parentgroupDefault list twoRate parent-group
                        PGShared]
                     
                     user@host# parent-group parent-group-name
                     user@host# set parent-group PgInternet

(Optional) Follow the instructions in this procedure for configuring the parent group.
