In the context of working with AAA (Authentication, Authorization, and Accounting) configurations, method2 implies that it serves as an optional second method for authorizing access. When configuring AAA, the primary method (often referred to as method1) is the primary mechanism that will be used to evaluate access permissions.

If method1 fails or cannot be applied for any reason, method2 acts as a fallback or secondary option. This allows network administrators to implement redundancy in their authorization methods without forcing the system to rely solely on a single method. Such a setup enhances flexibility and resilience in authorization processes, as it provides a backup method should the primary one encounter issues or restrictions.

It's important to understand that method2 being optional does not affect the necessity of having a defined primary method; rather, it serves to supplement it. In many configurations, particularly in environments where security needs are strict or where diverse user groups with varying access needs exist, leveraging optional methodologies like method2 can be significantly advantageous. This can contribute to a more robust AAA infrastructure.
