Classifying Congestion Points

Use the following configuration statements to configure congestion point classification scripts:

shared acp congestion-point-classifier rule name { 
     target target; 
     script script; 
} 

shared acp congestion-point-classifier rule name condition name ... 

Changes that you make to classification scripts do not affect subscriber sessions that are already established.

Configuring Targets and Criteria for Classification Scripts

To define a target and criteria for the congestion point classification script:

  1. From configuration mode, access the configuration statement that configures congestion point scripts. In this sample procedure, the scripts are configured in the config group.
  2. user@host# edit shared acp group config congestion-point-classifier rule name 
    
    
    

Enter a name for the congestion point classification script.

  1. Specify the target for the classification script.
  2. [edit shared acp group config congestion-point-classifier rule name] 
    
    user@host# set target target 
    
    
    

For information about classification targets, see Configuring Congestion Point Classification Targets.

  1. Specify the classification criteria for the target.
  2. [edit shared acp group config congestion-point-classifier rule name] 
    
    user@host# set script script 
    
    
    

For information about classification criteria, see Selecting Congestion Point Classification Criteria.

Configuring Classification Scripts Contents for Classification Scripts

To use the contents of a classification script to another object for the congestion point classification script:

Enter a name for the congestion point classification script and the name of the classification script that you want to use.

Configuring Congestion Point Classification Targets

The target of the congestion point classification script is an LDAP search string. The search string uses a syntax similar to an LDAP URL (see RFC 2255—The LDAP URL Format (December 1997)). The syntax is:

baseDN [ ? [ attributes ] [ ? [ scope ] [ ? [ filter ] ] ] ] 

With the exception of baseDN all the fields are optional.

The result of the LDAP search must be exactly one directory object. If no object or more than one object is found, congestion points for the subscriber are not loaded and all service activations for the subscriber are denied.

Selecting Congestion Point Classification Criteria

Congestion point classification criteria define match criteria that are used to find the congestion point profile. Use the fields in this section to define classification criteria.
