videooptimization policylabel

The following operations can be performed on "videooptimization policylabel":

add | rm | bind | unbind | show | stat | rename

add videooptimization policylabel

Creates a user-defined videooptimization policy label, to which you can bind policies.A policy label is a tool for evaluating a set of policies in a specified order. By using a policy label, you can configure the videooptimization feature to choose the next policy, invoke a different policy label, or terminate policy evaluation completely by looking at whether the previous policy evaluated to TRUE or FALSE.

Synopsys

add videooptimization policylabel <labelName> [-policylabeltype ( videoopt_req | videoopt_res )] [-comment <string>]

Arguments

labelName

Name for the Video optimization policy label. Must begin with a letter, number, or the underscore character (_), and must contain only letters, numbers, and the hyphen (-), period (

.) hash (#), space ( ), at (@), equals (=), colon (:), and underscore characters. Cannot be changed after the videooptimization policy label is added.

The following requirement applies only to the NetScaler CLI:

If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my videooptimization policy label" or my videooptimization policy label').

policylabeltype

Type of responses sent by the policies bound to this policy label. Types are:

  • HTTP - HTTP responses.

  • OTHERTCP - NON-HTTP TCP responses.

Possible values: videoopt_req, videoopt_res

Default value: NS_PLTMAP_RSP_REQ

comment

Any comments to preserve information about this videooptimization policy label.

Example

add videooptimization policylabel videoopt_label

rm videooptimization policylabel

Removes a videooptimization policy label.

Synopsys

rm videooptimization policylabel <labelName>

Arguments

labelName

Name of the videooptimization policy label to remove.

Example

rm videooptimization policylabel videoopt_label

bind videooptimization policylabel

Binds the specified videooptimization policy to the specified policy label.

Synopsys

bind videooptimization policylabel <labelName> -policyName <string> -priority <positive_integer> [-gotoPriorityExpression <expression>] [-invoke (-labelType ( vserver | policylabel ) -labelName <string>) ]

Arguments

labelName

  • If labelType is policylabel, name of the policy label to invoke.

  • If labelType is reqvserver or resvserver, name of the virtual server.

policyName

Name of the policy to bind to the videooptimization policy label.

priority

Positive integer specifying the priority of the policy. A lower number specifies a higher priority. Must be unique within the label. Policies are evaluated in the order of their priority numbers

, and the first policy that matches the request is applied.

Minimum value: 1

Maximum value: 2147483647

gotoPriorityExpression

Expression or other value specifying the next policy to evaluate if the current policy evaluates to TRUE. Specify one of the following values:

  • NEXT - Evaluate the policy with the next higher priority number.

  • END - End policy evaluation.

  • USE_INVOCATION_RESULT - Applicable if this policy invokes another policy label. If the final goto in the invoked policy label has a value of END, the evaluation stops. If the final goto is any

thing other than END, the current policy label performs a NEXT.

  • A default syntax or classic expression that evaluates to a number.

If you specify an expression, the number to which it evaluates determines the next policy to evaluate, as follows:

  • If the expression evaluates to a higher numbered priority, the policy with that priority is evaluated next.

  • If the expression evaluates to the priority of the current policy, the policy with the next higher numbered priority is evaluated next.

  • If the expression evaluates to a number that is larger than the largest numbered priority, policy evaluation ends.

An UNDEF event is triggered if:

  • The expression is invalid.

  • The expression evaluates to a priority number that is smaller than the current policys priority number.

  • The expression evaluates to a priority number that is between the current policy's priority number (say, 30) and the highest priority number (say, 100), but does not match any configured prior

ity number (for example, the expression evaluates to the number 85). This example assumes that the priority number increments by 10 for every successive policy, and therefore a priority number of

85 does not exist in the policy label.

invoke

If the current policy evaluates to TRUE, terminate evaluation of policies bound to the current policy label and evaluate the specified policy label.

labelType

Type of policy label to invoke. Available settings function as follows:

  • vserver - Invoke an unnamed policy label associated with a virtual server.

  • policylabel - Invoke a user-defined policy label.

Possible values: vserver, policylabel

Example

   i)      bind videooptimization policylabel videoopt_label pol_videoopt 1 2        ii)     bind videooptimization policylabel videoopt_label pol_videoopt 1 2 -invoke vserver CURRENT

unbind videooptimization policylabel

Synopsys

unbind videooptimization policylabel <labelName> -policyName <string> [-priority <positive_integer>]

Arguments

labelName

Name for the Video optimization policy label. Must begin with a letter, number, or the underscore character (_), and must contain only letters, numbers, and the hyphen (-), period (

.) hash (#), space ( ), at (@), equals (=), colon (:), and underscore characters. Cannot be changed after the videooptimization policy label is added.

The following requirement applies only to the NetScaler CLI:

If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my videooptimization policy label" or my videooptimization policy label').
