How to install Cisco Stealthwatch Flow Sensor 3200 Network Monitoring Appliance

• Prepare the deployment environment by validating network topology, ensuring you have a supported Stealthwatch manager in place, and confirming power, cooling, and rack space meet the appliance requirements.
• Rack-mount the Flow Sensor 3200 in a suitable data center cabinet, connect power, and ensure proper grounding and cable management for optimal airflow and easy serviceability.
• Connect data interfaces to appropriate tap or span ports across the network segments where you want to capture flow data, and verify link integrity and proper velocity of traffic to the appliance.
• Power on the appliance and access the management console through the designated network segment. Complete initial configuration, including network settings, time synchronization, and secure administrative credentials.
• Associate the Flow Sensor with your Cisco Stealthwatch management instance, configure flow collection parameters, and define data retention, alert thresholds, and correlation rules that align with your security policies.
• Import existing policy and threat intelligence as needed, start a baseline data collection period, and validate telemetry by monitoring dashboards, alerts, and system health indicators.
• Perform ongoing tuning to reduce false positives, adjust detection thresholds, and ensure synchronization with other security controls in your environment for cohesive incident response.
