NetFlow is a baseline form of telemetry that is recommended for network infrastructure devices. NetFlow is a technology that collects and exports information about IP traffic flows on enabled interfaces. NetFlow can provide valuable insight into the network performance, utilization, behavior, and security. NetFlow can help identify anomalies, such as DDoS attacks, malware, or misconfigurations, by comparing the current traffic patterns with the normal or baseline ones. NetFlow can also help with capacity planning, troubleshooting, and forensic analysis. NetFlow is supported on various Cisco platforms, such as routers, switches, firewalls, and IPS sensors. NetFlow can export data to different collectors and analyzers, such as Cisco Security Monitoring, Analysis and Response System (CS-MARS), Cisco Traffic Anomaly Detectors and Cisco Guard DDoS Mitigation Appliances, Cisco Network Analysis Module (NAM), and other third-party tools.

Cisco Workload Optimization Manager (CWOM) is a decision-automation engine that provides workloads with the exact resources they need at the right time in accordance with business policies, freeing IT teams to focus on innovation rather than the maintenance of their IT environment1. CWOM is part of the Cisco SecureX platform, which integrates various security solutions, including endpoint protection platforms (EPPs), to provide a unified and simplified security experience2. CWOM does not deploy an AWS Lambda system, optimize a flow path, or set up a workload forensic score. These are not related to CWOM's functionality or EPP solutions. CWOM automates resource resizing, which means it can dynamically adjust the CPU, memory, disk, and network resources allocated to each workload based on real-time demand and performance metrics1. This helps EPP solutions to solely address performance issues by ensuring that workloads have the optimal resources to run efficiently and securely, without overprovisioning or underutilizing resources3.

How To Troubleshoot ISE Failed Authentications & Authorizations
Check the ISE Live Logs
Login to the primary ISE Policy Administration Node (PAN).
Go to Operations > RADIUS > Live Logs
(Optional) If the event is not present in the RADIUS Live Logs, go to Operations > Reports > Reports > Endpoints and Users > RADIUS Authentications Check for Any Failed Authentication Attempts in the Log
