30 Citrix NetScaler Policy Configuration and Reference Guide
Configuring a Policy Label
A policy label consists of a set of policies and invocations of other policy labels
and virtual server-specific policy banks. An Invoke parameter enables you to
invoke a policy label or a virtual server-specific policy bank from any other
policy bank. A special-purpose NoPolicy entry enables you to invoke an external
bank without processing an expression (a rule). The NoPolicy entry is a
“dummy” policy that does not contain a rule.
For configuring policy labels from the NetScaler command line, note the
following elaborations of the command syntax:
•gotoPriorityExpression is configured as described in “Entries in a Policy
Bank,” on page 29.
•The type argument is required. This is unlike binding a conventional
policy, where this argument is optional.
• You can invoke the bank of policies that are bound to a virtual server by
using the same method as you use for invoking a policy label.
To configure a policy label by using the NetScaler command line
At the NetScaler command prompt, type:
bind cache|rewrite|responder policylabel <policylabelName>
-policyName <policyName> -priority <priority>
-gotoPriorityExpression <gotopriorityExpression> -invoke
reqvserver|resvserver|policylabel <policyLabelName>|<vserverName>
To invoke a policy label from a Rewrite policy bank with a NOPOLICY entry
by using the NetScaler command line
At the NetScaler command prompt, type:
bind rewrite global NOPOLICY <priority>
-gotoPriorityExpression <gotopriorityExpression>
-type REQ_OVERRIDE|REQ_DEFAULT|RES_OVERRIDE|RES_DEFAULT
-invoke reqvserver|resvserver|policylabel
<policyLabelName>|<vserverName>
To invoke a policy label from an Integrated Caching policy bank by using the
NetScaler command line
At the NetScaler command prompt, type:
bind cache global NOPOLICY -priority <priority>
-gotoPriorityExpression <gotopriorityExpression>
-type REQ_OVERRIDE|REQ_DEFAULT|RES_OVERRIDE|RES_DEFAULT
-invoke reqvserver|resvserver|policylabel
<policyLabelName>|<vserverName>
