The type of license you choose will impact how you manage and activate your Cisco ISE deployments and their functionality. Each license level unlocks specific functionalities which you must review. Proper license selection is crucial for ensuring optimal performance and compliance.

Traditional PAK vs Smart Licenses

Cisco Identity Services Engine (ISE) offers two primary licensing models⁚ traditional PAK licenses and Smart Licenses. Traditional PAK licenses are tied directly to a specific device and require manual activation using a Product Activation Key. This method can be cumbersome, especially in larger deployments, as each license needs to be managed individually. Smart Licenses, on the other hand, offer a more streamlined approach through Cisco’s Smart Software Licensing portal. With Smart Licensing, licenses are not tied to specific devices but to a virtual account, enabling easier management and license pooling. This flexibility allows for better resource utilization and simplified license transfer. Smart Licensing also provides enhanced visibility into license usage, aiding in better planning and compliance. The choice between PAK and Smart Licenses depends on factors such as deployment size, IT infrastructure, and the desired level of management simplicity. Smart licenses are generally preferred for their flexibility and ease of use.

Concurrent Active Endpoint Count

Cisco ISE licensing is fundamentally tied to the concept of concurrent active endpoints. Each ISE license tier, whether Essential, Advantage, or Premier, includes a specific count value that determines the maximum number of active endpoints the deployment can simultaneously support. This count refers to the devices actively using the specific features licensed within that tier at any given moment. For example, if you have a Premier license with a count of 1000, your deployment can support up to 1000 endpoints using Premier-level features concurrently. It’s crucial to understand this metric, as exceeding the licensed count can lead to functionality limitations. The concurrent active endpoint count is not the total number of devices connected to the network but rather the number actively utilizing ISE features. Monitoring this count is vital for ensuring optimal performance and compliance with the license terms. Careful planning is essential to avoid exceeding the limits and ensure uninterrupted service.

Cisco ISE License Tiers⁚ Essential, Advantage, Premier

Cisco ISE licenses are structured into three distinct tiers⁚ Essential, Advantage, and Premier. Each tier provides a different set of features and capabilities, catering to varying network security needs. The Essential tier typically offers basic network access control functionalities, suitable for organizations with simpler requirements. The Advantage tier builds upon the Essential tier, adding advanced features such as enhanced profiling and posture assessment. The Premier tier represents the highest level, incorporating all available ISE functionalities, including advanced threat containment and security group tagging. The authorization features used when authenticating endpoints dictate the necessary license tier; Premier licenses cover any endpoint authorized with Premier or Advantage. Selecting the appropriate tier depends on the specific security policies and features your organization requires. Understanding the differences between these tiers is crucial for cost-effective and efficient deployment.

Guest Access Options in ISE

Cisco ISE provides three primary methods for enabling guest access to a network⁚ Hotspot, Self-Registration, and Sponsored Guest access. Hotspot access offers immediate, non-credentialed network connectivity, typically used in public areas or events where quick access is needed without user accounts. Self-Registration allows guests to create their own accounts through a portal, requiring them to input minimal information before gaining access. Sponsored Guest access requires a designated employee to create or approve guest accounts, providing a higher level of control and security. Each method caters to different scenarios and security requirements. Furthermore, ISE provides robust APIs to integrate with other systems, such as vendor management platforms, to facilitate the creation, modification, and deletion of guest accounts. Selecting the suitable guest access method depends on the context and the level of security needed for your network environment.
