For example, if patch 3 is installed on your Cisco ISE servers, you cannot install or roll back patch 1 or 2. Similarly, you cannot roll back changes of a lower-version patch if a higher version is currently installed on Cisco ISE. You cannot install a patch with a version that is lower than the patch that is currently installed on Cisco ISE. All events on PSN personas are relied to MnT primary and secondary nodes.Cisco ISE patches can be installed on ISE-PIC as well. The MnT role is reverted for load sharing purposes. All configuration and maintenance tasks are done in Primary Administration Node and settings are propagated across whole deployment in the same time. Node 1 takes role of Primary Administration Node and Node 2 takes role of Secondary Administration Node. Administration Persona is active on two nodes. PSN nodes act as a radius servers for network devices and there are four of them.

Secondary is manually promoted to PrimaryД®xample of mid-sized distribution deployment.

Primary fails and there is PAN Failover configured.

Secondary GUI is available for configuration only when:

Secondary вЂ“ role in distributed deployment where for example administration persona is secondary for configuration tasks.

Primary вЂ“ role in distributed deployment where for example administration persona is the primary for all configuration tasks.

Standalone вЂ“ related to standalone deployment вЂ“ node is not aware of each other and acts alone.

Role вЂ“ Applies to Administration and Monitoring nodes.

Monitoring (MnT) вЂ“ monitoring node is responsible for logs aggregation across deployment.

To achieve radius traffic sharing you can scale the PSNs up.

Policy Service (PSN) вЂ“ Policy Service Node is a node that handles traffic between network devices and ISE (its IP is used as Radius for devices).

This persona provides full access to administration GUI Administration (PAN) вЂ“ Administration Node is a single point of ISE deployment configuration.Persona/Node Type вЂ“ This one is often used interchangeable and determines the service provided by particular node:.Node вЂ“ Individual instance вЂ“ Physical Appliance or Virtual Appliance.To better understand the deployment modes it is wise to get familiar with the ISE nomenclature. One node deployment (aka standalone) is suitable for PoC projects or lab / testing environments where no high availability is required. There is no strict requirement and we saw many quite large designs based on small deployment type. Distributed Deployment (built with more than one ISE nodes)Д®xample of medium-scale distributed deployment.Дepending on your organization requirements, scale, number of users and sites you need to choose one of available deployments.Standalone Deployment (built on one ISE node).Choosing the deployment option, it is worth to mention possibilities.

Implementing Cisco ISE you should be aware of the deployment modes and architectural functionality available from Cisco. Anyway despite the Radius is the primary communication protocol between ISE and network devices, there are a bunch of refinements to legacy solutions like Radius Change of Authorization flows, OS and devices profiling, posture assessment procedures for security compliance alignment, 3rd party devices onboarding, or guest portal redirection methods. The fundamental principle for ISE is to act as a Radius server. Based on configured rules ISE is able to provide granular access rights to services based on many factors and contexts like AD group membership, the physical location of the user, device type, OS version, time of day, and more. ISE is a point of the network where all network access methods and identities are verified against defined ruleset and authentication sources.
