The secondary supports the primary in the event of a loss of connectivity between the network devices and the primary. The primary node provides all the configuration, authentication and policy functions and the secondary node functions as a backup. The smallest distributed ISE deployment consists of two Cisco ISE nodes with one node functioning as the primary. If you ran a standalone solution on your production network you have no redundancy. This is suitable for a small deployment or lab solution. This consists of one node which runs all three personas. ISE has two different deployment options – Standalone and Distributed Standalone Deployment How Cisco ISE Works – Cisco ISE Deployment options

The Policy Services Node is the contact point into the network. Every event that occurs within the ISE topology is logged to the monitoring node you can then generate reports showing the current status of connected devices and unknown devices on your network. The Monitoring Node is where all the logs are collected and where report generation occurs. It handles all system related configurations and can be configured as standalone, primary or secondary. Once configured on the PAN the changes are pushed out to the policy services nodes. The Policy Administration Node is where the administrator logs into to configure policies and make changes to the entire ISE system. Lets go through each persona and explain their function. The ISE solution is made up of a deployment of nodes with three different ISE personas:ĭepending on the size of your deployment all three personas can be run on the same device or spread across multiple devices for redundancy and scalability. Any devices that do not pass authorisation will be placed into a guest vlan or denied access to the network.Īll this information is logged and you can instantly get a view of what is connected to your network at any time.

Based on many factors including the validity of a certificate, mac address or device profiling you can identify a machine and determine which vlan that machine is placed into. It can authenticate wired, wireless and vpn users and can scale to millions of endpoints. In simple terms you can control who can access your network and when they do what they can get access to. Some people think it is Cisco ICE, this is how it’s pronounced, but the correct acronym is ISE – Identity Services Engine. In this Cisco ISE overview we are going to cover all the basic concepts so by the end of the post you will be able to explain all the basic concepts.
