•Invoke: Optional. Invokes another policy bank.
Configuring a Policy Bank for a Virtual Server
You can configure a bank of policies for a virtual server. The policy bank can
contain individual policies, and each entry in the policy bank can optionally
invoke a policy label or a bank of policies that you configured for another virtual
server. If you invoke a policy label or policy bank, you can do so without
triggering an expression (a rule) by selecting a NOPOLICY “dummy” entry
instead of a policy name.
To add policies to a virtual server policy bank by using the NetScaler
command line
At the NetScaler command prompt, type:
bind lb|cs vserver <virtualServerName> -policyName <policyName>
-priority <positiveInteger> -gotoPriorityExpression <expression>
-type REQUEST|RESPONSE
To invoke a policy label from a virtual server policy bank with a NOPOLICY
entry by using the NetScaler command line
At the NetScaler command prompt, type:
bind lb|cs vserver <virtualServerName> -policyName
NOPOLICY_REWRITE|NOPOLICY_CACHE|NOPOLICY_RESPONDER -priority
<integer> -type REQUEST|RESPONSE -gotoPriorityExpression
<gotopriorityExpression> -invoke reqVserver|resVserver|policyLabel
<vserverName>|<labelName>
Example
bind lb vserver myLoadBalancingVserver1 -policyname
NOPOLICY-REWRITE -priority 200 -type REQUEST
-gotoPriorityExpression NEXT -invoke policyLabel myPolicyLabel
To configure a virtual server policy bank by using the configuration utility
1. In the left navigation pane, expand Load Balancing, Content Switching,
SSL Offload, AAA - Application Traffic, or Access Gateway, as
appropriate, and then click Virtual Servers.
2. In the details pane, select the virtual server that you want to configure, and
then click Open.
