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:
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-classifierCreate 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-1Configure 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 targetIf 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 nameConfigure 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 includewhere include is a reference to an existing script that is included in the script you are configuring.
(Optional) Change the order of rules.
[edit shared sae group east-region dhcp-classifier]user@host# insert rule rule-5 before rule-4(Optional) Rename a rule.
[edit shared sae group east-region dhcp-classifier]user@host# rename rule rule-2 to dhcp(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; }(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; } }
