Configure Policies

An active visibility policy defines conditions and actions. When all conditions are met, all actions are executed. The policy ties the conditions and actions together.

A policy must have at least one condition. An action is not required.

Up to five (5) conditions can be specified in a policy. The parameters and values that are specified in the condition depends on the condition. The policy is executed only when all conditions are met.

Within a policy, there is one unique condition. For example, there can only be one PortUp condition, not multiple PortUp conditions within a policy.

Up to five (5) actions can be specified in a policy. The parameters and values that are specified in the action depends on the action.

Within a policy, there can be multiple actions, including the same action. For example, there can be multiple PortEnable actions within a policy.

A policy is triggered if all the conditions are met. Then all the actions are executed. If there are five conditions in the policy, they all have to be met before the action or actions are executed. If there are multiple actions, they are executed in sequence, as specified in the policy. The policy specifies the priority of the actions.

When there are multiple actions, they will continue to be executed even if there is an error. For example, if there are three actions and there is an error with the second action, the first and third actions will be executed. When the policy executes, each action will have their status reported (success or failure).

Multiple policies can be in effect at the same time. The policies can monitor different conditions and take different actions. Up to 100 policies per cluster can be defined.

A policy must be enabled for it to become active. However, when you first create a policy, you might want to disable it so that it does not become active right away.

When a policy is triggered, an SNMP event and email notification (policytrigger) can optionally be generated.
