Configuring Policies for IMS
For IMS environments, you can configure JUNOSe policies. When you configure classify-traffic conditions, you can set up the software so that the SAE expands into multiple classifiers before it installs the policy on the router. If you enter a comma-separated list of values in the source and destination network (IP address, mask, and IP operation) or port fields (for port-related protocols), the software creates a classifier for each possible combination of address and port. Note that the software does not expand classifiers for values that are entered as a range.
For example, the source configuration in the classify-traffic condition in Figure 25 would cause the condition to be expanded into four classifiers that have the following combination of source addresses and source ports:
192.1.1.0/255.255.255.0 eq 8192.1.1.0/255.255.255.0 eq 8080192.2.1.1/255.255.255.0 eq 8192.2.1.1/255.255.255.0 eq 80

Enabling Expansion of JUNOSe Classify-Traffic Conditions
To use SDX Configuration Editor to enable the expansion of JUNOSe classify-traffic conditions:
- In the navigation pane, select a configuration file for the SAE that you want to configure.
- Select the Miscellaneous tab, and expand the Policy Management Configuration section.

- Edit or accept the default value.
See Enable JUNOSe Classifier Expansion Field.
- Select File > Save.
- Right-click the configuration file, and select SDX System Configuration > Export to LDAP Directory.
Enable JUNOSe Classifier Expansion Field
In SDX Configuration Editor, you can edit the following field in the Policy Management Configuration section of the Miscellaneous pane in an SAE configuration file.
Enable JUNOSe Classifier Expansion
- Specifies whether or not the SAE expands the JUNOSe classify-traffic conditions into multiple classifiers before it installs the policy on the router.
- Value—Yes or No
- Guidelines—Because classifier expansion uses processing resources when the policy is created, you should set this property to true only if you are going to use the feature.
- Default—No
