Configuring Service Rules
Note This is a licensed feature. Please ensure that you have purchased a Service Rule license for this advanced
feature.
The Rules Template licensed feature provides a flexible mechanism to specify configurable caching
requests by allowing these requests to be matched against an arbitrary number of parameters, with an
arbitrary number of policies applied against the matches. You can specify a set of rules, each clearly
identified by an action and a pattern. Subsequently, for every incoming request, if a pattern for a rule
matches the given request, the corresponding action for that rule is taken.
Note The processing time on the SE is directly related to the number of service rules configured. Processing
times increase with an increase in the total number of rules configured. If the SE processing time is
greater than twice the datafeed poll rate, then the device goes offline until the processing is completed.
You can avoid this by configuring a higher datafeed poll rate. The recommended datafeed poll rate for
750 service rules is 300 seconds. To configure the datafeed poll rate, see the “Configuring System
Settings” section on page 6-6.
Configuring a service rule consists of the following tasks:
• Enabling the service rules. (Only needs to be performed once.)
• Configuring a pattern list and adding a pattern to it.
• Associating an action with an existing pattern list.
To configure or edit service rule settings, do the following:
Step 1 Choose Devices > Devices > Service Control > Enable Rules. The Enable Service Rules page is
displayed.
Step 2 Check the Enable check box to enable the use of rule settings.
Step 3 Click Submit to save the settings.
Step 4 Choose Devices > Devices > Service Control > Service Rules. The Service Rules Table page is
displayed.
Step 5 Aggregate Settings is set to Yes by default. If this SE belongs to a device group, and the settings have
not been configured using the device group, you can enter the settings and they will apply to the device
group as well.
If the settings are previously configured through the device group, the current configuration is displayed
for view only. New settings must be configured through the associated device group.
If you want to configure settings for this SE only, and override the device group settings on this SE, set
Aggregate Settings to No.
If you remove all device group settings, all device settings displayed with Aggregate Settings enabled
are removed as well.
