Reliable, easy to deploy, and cost-effective. The WS-X4124-FX-MT card ensures smooth voice communication across our infrastructure.
The WS-X4124-FX-MT Catalyst 4500 NetFlow Services Card is a high-performance module for Cisco Catalyst 4500 Series switches (Supervisor IV/V) that delivers advanced NetFlow data collection, traffic analysis, and real-time network monitoring for optimized performance and security.
The WS-X4124-FX-MT card is fully compatible with Cisco Catalyst 4500 Supervisor Engine IV and Supervisor Engine V, ensuring seamless integration and line-rate flow processing in your campus or data center deployment.
By exporting granular flow records and supporting NetFlow v5, v9 and IPFIX, the WS-X4124-FX-MT enables deep traffic analysis, bandwidth utilization tracking, anomaly detection, and capacity planning for faster troubleshooting and better resource allocation.
Key features include hardware-accelerated flow preprocessing, support for up to 24 Gigabit Ethernet ports, up to 1 million concurrent flow entries, on-board buffering for burst traffic, and full NetFlow v5/v9/IPFIX compatibility.
The Catalyst 4500 NetFlow Services Card can process and store up to 1 million concurrent flow records and sustain export rates exceeding 500,000 flows per second when paired with Supervisor Engines IV or V.
The WS-X4124-FX-MT card supports NetFlow v5, NetFlow v9, and IPFIX standards, providing broad interoperability with leading flow collectors, analytics platforms, and security information and event management (SIEM) systems.
Installation requires a Cisco Catalyst 4500 chassis with Supervisor Engine IV or V. Insert the WS-X4124-FX-MT module into an available expansion slot, secure it, power-cycle the switch, and verify module status via the CLI.
No additional license is required. NetFlow Services Card functionality is included in Cisco IOS Software releases for Supervisor Engines IV and V. Simply ensure your IOS version supports NetFlow features.
In global config, enable NetFlow on interfaces with 'ip flow ingress' or 'ip flow egress', define a flow exporter using 'flow exporter', set collector IP/port, create a flow monitor with 'flow monitor', and apply it to interfaces. Save the configuration.
The WS-X4124-FX-MT offloads flow processing to dedicated hardware, minimizing CPU load on the Supervisor Engine and maintaining full line-rate packet forwarding while delivering detailed traffic insights.
The NetFlow Services Card interfaces with up to 24 internal Gigabit Ethernet channels from front-line line cards in the Catalyst 4500 chassis, delivering flow data without additional external cabling.
Firmware updates are managed via the Supervisor Engine’s Cisco IOS Software. Use 'archive download-sw' or 'software install' commands with the latest IOS image, which automatically updates the WS-X4124-FX-MT firmware.
Verify module status with 'show module' and 'show flow processing resource', confirm NetFlow settings via 'show ip flow export' and 'show flow monitor', check collector connectivity, and review system logs for errors.
