Classifying DHCP Subscribers (SRC CLI)

Use the following configuration statements to configure DHCP classification scripts:

A classification script can contain either a target and a condition or a script. If you do not define a script, the classifier must have both a target and a condition.

To configure DHCP classification scripts:

1. From configuration mode, enter the DHCP classifier configuration. In this sample procedure, the classifier is configured in the east-region SAE group.
   user@host# edit shared sae group east-region dhcp-classifier
2. Create a rule for the classifier. You can create multiple rules for the classifier.
   [edit shared sae group east-region dhcp-classifier]user@host# edit rule rule-1
3. Configure either a target or a script for the rule.
   • Configure the target for the rule. If you configure a target, see Syntax for DHCP Classification Targets.
     [edit shared sae group east-region dhcp-classifier rule rule-1]user@host# set target target

     If you configured a target for the rule, you must configure a match condition for the rule. You can create multiple conditions for the rule. See DHCP Classification Conditions.

     [edit shared sae group east-region dhcp-classifier rule rule-1]user@host# edit condition name
   • Configure the script for the rule.
     [edit shared sae group east-region dhcp-classifier rule rule-1]user@host# edit script

     (Optional) You can specify a script target.

     [edit shared sae group east-region dhcp-classifier rule rule-1 script]user@host# set script-value

     (Optional) You can include a script that has already been created.

     [edit shared sae group east-region dhcp-classifier rule rule-1 script]user@host# set include include

     where include is a reference to an existing script that is included in the script you are configuring.

4. (Optional) Change the order of rules.
   [edit shared sae group east-region dhcp-classifier]user@host# insert rule rule-5 before rule-4
5. (Optional) Rename a rule.
   [edit shared sae group east-region dhcp-classifier]user@host# rename rule rule-2 to dhcp
6. (Optional) Verify the classifier rule configuration.

   [edit shared sae group east-region dhcp-classifier rule rule-1]
   user@host# show 
   target cn=default,<-dhcpProfileDN->;
   condition {
    1;
   }

7. (Optional) Verify the DHCP classifier configuration.

   [edit shared sae group east-region dhcp-classifier]
   user@host# show 
   rule rule-1 {
     script "# DHCP classification script
   #
   # The DHCP classification script can use the following fields:
   #
   # interfaceName          - interface where DHCP DISCOVER was received.
   # ifAlias                - \"ip description\" of interface
   # ifDesc                 - SNMP standard name of interface
   # nasPortId              
   # virtualRouterName      - VR where DHCP DISCOVER was received
   # macAddress             - MAC address of DHCP client
   # dhcp                   - DHCP options
   # poolName               - DHCP Pool name set by authorization plug-in
   # authVirtualRouterName  - VR name set by authorization plug-in
   # dhcpProfileDN          - search base for DHCP Profiles

   ";
   }
   rule rule-2 {
     target cn=default,<-dhcpProfileDN->;
     condition {
       1;
     }
   }
