Maximum Number of Access Control Rules and Intrusion Policies

The maximum number of access control rules or intrusion policies that are supported by a target device depends on many factors, including policy complexity, physical memory, and the number of processors on the device.

If you exceed the maximum supported by your device, you cannot deploy your access control policy and must reevaluate.

Guidelines for intrusion policies:

  • In an access control policy, you can associate one intrusion policy with each Allow and Interactive Block rule, as well as with the default action. Every unique pair of intrusion policy and variable set counts as one policy.

  • You may want to consolidate intrusion policies or variable sets so you can associate a single intrusion policy-variable set pair with multiple access control rules. On some devices you may find you can use only a single variable set for all your intrusion policies, or even a single intrusion policy-variable set pair for the whole device.
