Introducing Local Traffic Policies

The BIG-IP system provides Local Traffic Policies that simplify the way in which you can manage traffic associated with a virtual server. Using policies involves three basic steps: you create a draft policy, publish the policy, and then associate the published policy with a virtual server. Each policy includes a matching strategy for the specified rules, as well as conditions and actions configured within each rule, to manage traffic.

Note: Local Traffic Policies that have been upgraded from BIG-IP software version 12.0, or earlier, appear in the Published Policies list.

Basic steps for creating and using policies

BIG-IP local traffic policies comprise a prioritized list of rules that match defined conditions and run specific actions, which you can associate with a virtual server that directs traffic accordingly. For example, you might create a policy that determines whether a client is using a mobile device, and then redirects its requests to the applicable mobile web site’s URL.

Each BIG-IP local traffic policy requires a matching strategy to determine which rule applies if more than one rule matches.

The BIG-IP local traffic policies provide three predefined policy matching strategies: a first-match, best-match, and all-match strategy. Each policy matching strategy prioritizes rules according to the rule’s position within the Rules list.

As needed, you can create a user-defined best-match strategy to customize the precedence (order of preference) of added operands and selectors. For example, to meet your preferred operand and selector combinations, you might create a user-defined best-match strategy that changes the precedence of added operands and selectors, compared to the predefined best-match strategy.

Note: In a best-match or first-match strategy, a rule without conditions becomes the default rule, when the rule is the last entry in the Rules list.

Matching strategy

Description

all-match strategy

An all-match strategy starts the actions for all rules in the Rules list that match. Note: In an all-match strategy, when multiple rules match, but specify conflicting actions, only the action of the best-match rule is implemented. A best-match rule can be the lowest ordinal, the highest priority, or the first rule that matches in the Rules list.

best-match strategy

A best-match strategy selects and starts the actions of the rule in the Rules list with the best match, as determined by the following factors.1. A best-match strategy selects the rule with the most conditions, ignoring details about the conditions. 2. If a rule with the most conditions is not determined, then the best-match strategy selects the rule with the highest priority condition types. The best-match strategy sorts the condition types, highest priority first, comparing one at a time until a higher priority is found. For example, a priority sequence of 0,1,3,4,6 wins over 0,1,3,5,7 because 4 is a higher priority than 5. 3. If a rule with the highest priority condition types is not determined, then the best-match strategy selects the rule with equal match types over other match types, such as starts-with, ends-with, or contains, and processes according to condition type priority. 4. If a rule of equal match types is not determined, then the best-match strategy uses an ordinal (the precedence of the operand).

Note: In a best-match strategy, when multiple rules match and specify an action, conflicting or otherwise, only the action of the best-match rule is implemented. A best-match rule can be the lowest ordinal, the highest priority, or the first rule that matches in the Rules list.

first-match strategy

A first-match strategy starts the actions for the first rule in the Rules list that matches.

BIG-IP local traffic policy rules match defined conditions and start specific actions. You can create a policy with rules that are as simple or complex as necessary, based on the passing traffic. For example, a rule might simply determine that a client’s browser is a Chrome browser that is not on an administrator network, and restrict access to certain administrative tools. Or a rule might determine that a request URL starts with /video, that the client is a mobile device, and that the client’s subnet does not match 172.27.56.0/24, and then that the request to a video file is designed for mobile devices on a Content Delivery Network (CDN).

Local traffic policy rules provide you with different types of logical operators for matching conditions, which are determined by the order and configuration of the conditions within and between the rules. The different types of logical operators that you can configure are AND logical operators for conditions within a rule, and OR logical operators for values within a condition and for conditions between rules. When AND logical operators apply, then all logical operators must match the matching strategy. When OR logical operators apply, then any logical operator must match the matching strategy.

When you create a rule, you can configure two or more conditions that use AND logic within that rule. For example, you can create Rule1 with two conditions, a and b, which use AND logic when Rule1 is used by the matching strategy. This means that all conditions within a rule must succeed in order to be used by a matching strategy.

When you configure multiple values within a condition, OR logic determines if any matching value within the condition succeeds. For example, you can create a condition configured with two or more values. The matching strategy uses OR logic to determine if any configured value matches.

Similarly, when you create two or more rules, you can configure each rule with applicable conditions that use OR logic between the rules. For example, you can create Rule1 with a set of conditions, and Rule 2 with another set of conditions. The matching strategy uses OR logic to determine if a rule matches.

These examples show the logical operation of three conditions (a, b, and c) and two rules (Rule1 and Rule2).

In this first example, consider the following scenario, where you want to match condition a or b, and c ((a | b) & c). You can configure this logic by creating Rule1 to use conditions a and c (a & c), and Rule 2 to use conditions b and c (b & c). The result is when Rule1 matches the strategy, conditions a and c (a & c) are used, or when Rule 2 matches, conditions b and c (b & c) are used.

In this second example, consider the scenario where you want to match conditions a and b, or c ((a & b) | c). You can configure this logic by creating Rule1 to use conditions a and b, and Rule2 to use condition c. The result is when Rule1 matches the strategy, both conditions a and b are used, or when Rule2 matches the strategy, condition c is used.

The conditions for a local traffic policy rule define the necessary criteria that must be met in order for the rule’s actions to be applied. For example, a policy might include the following condition type and settings, which, when met by a request, would allow the rule’s specified actions to be applied.

Set variable

Sets a Tcl variable in the runtime environment.

Certain BIG-IP local traffic policy actions support Tcl command substitutions, giving you significant flexibility in configuring policies. Tcl command substitutions provide quick, read-only access to immediately available runtime data, such as information about a current request’s URI, or a header or cookie in the request or response.

Important: Any Tcl command that requires a delay, for example, the after command, or that requires waiting for results from a request outside of the Traffic Management Microkernel (TMM), is not supported and might not succeed.

When using Tcl command substitutions, the following guidelines apply.

  • Memory and CPU capacity determine a maximum number of rules for active policies; however, excessive Tcl command substitutions can degrade performance.
  • Tcl command substitutions are primarily intended for reading and returning data.

The following Tcl command is an example of a Tcl command substitution that can be used within a policy.

"tcl:[HTTP::uri]"

Note: Each Tcl command must include a prefix of tcl:. If the tcl: prefix is omitted, the command is interpreted as a plain string.

You can apply options to conditions and actions, as determined by the selected condition or action type. For example, you might want to constrain a condition based on the case-sensitivity of a string, which is easily applied by selecting the applicable option for that condition.
