The 120Gbps fabric upgrade is a fantastic boost for our 12406. It provides the capacity we needed for our regional aggregation layer with great stability.
Robust and reliable throughput. This 3xSFC and 2xCSC bundle is a cost-effective way to scale your 6-slot chassis for modern data loads.
Excellent switching performance. The 120G fabric is rock solid under heavy load, ensuring our network remains responsive and reliable for all users.
Professional grade scalability. The upgrade process was seamless and the improvement in bandwidth was immediate and substantial. Very satisfied with the results.
Steady and efficient. This enhanced fabric handles high-speed links with ease, making it a critical component for our service provider network.
The 12406E/120 is a 120 Gbps enhanced fabric module designed to deliver ultra-high bandwidth for the Cisco 12406 Router, featuring three Scalable Fabric Cards (SFC) and two Connectivity Switch Cards (CSC).
The 12406E/120 module is fully compatible with Cisco 12406 chassis running Cisco IOS XR and cannot be installed in other 12000 Series platforms.
This enhanced module provides five fabric planes—three SFCs for chassis switching and two CSCs for system interconnect—to deliver non-blocking, meshed connectivity across all line cards.
SFCs handle high-speed data forwarding across the chassis, while CSCs manage control-plane connectivity between supervisor engines and line cards, ensuring balanced data and control traffic.
No. Cisco requires all fabric modules in a single 12406 chassis to be identical; mixing enhanced and standard fabrics is unsupported and may cause chassis instability.
Each slot achieves up to 120 Gbps of bidirectional bandwidth, ensuring headroom for high-density 10/40/100 GbE line cards under peak traffic loads.
Yes. The enhanced five-plane architecture guarantees non-blocking switching fabric performance across all installed line cards, eliminating oversubscription.
The module draws a maximum of 250 W and requires adequate chassis cooling; ensure your Cisco 12406 meets power‐supply redundancy and airflow guidelines per the installation guide.
The module is supported from Cisco IOS XR Release 5.3.4 onward. Verify software compatibility via the Cisco Feature Navigator before deployment.
Power down the router, insert the module into a designated fabric slot, secure the captive screws, reconnect power, and validate fabric status via CLI commands show platform fabric.
Use the IOS XR CLI commands show platform virtual-fabric plane and show controllers fabric-switch to view real-time throughput, error counters, and plane status.
With five fabric planes, the 12406E/120 supports active/standby and load-sharing topologies. In case of plane failure, traffic automatically reroutes across remaining planes.
No additional fabric licenses are needed. The module operates under the existing Cisco IOS XR fabric entitlement included with your router’s software contract.
The 12406E/120 carries a one-year limited hardware warranty. Cisco SMARTnet contracts provide 24×7 hardware replacement, software updates, and technical support.
Order using SKU 12406E/120 via Cisco’s official sales channels or authorized partners. Include part number FL-12406E= for accurate procurement.
Yes. Remove existing standard fabric modules in pairs, then install two 12406E/120 units per chassis. Confirm software support and power headroom before upgrade.
