This 80Gbps enhanced scheduler card keeps our 12016 perfectly synchronized. It's a critical component for maintaining high-speed data integrity across all network slots.
Reliable and precise timing. This CSC module is a solid performer that ensures our switch fabric operates at peak efficiency with absolutely zero errors.
Professional grade scheduler. It was easy to install and has provided rock-solid stability for our metropolitan aggregation site for several months now.
Steady and dependable hardware. The enhanced timing precision has noticeably improved our overall chassis performance during high-traffic periods. Highly satisfied with this card.
Excellent quality and performance. This scheduler card is a vital part of our 12K maintenance strategy, ensuring 99.999% network uptime for our clients.
Drop-in replacement that worked flawlessly. The system recognized the card immediately, and we've seen a measurable drop in jitter across the switching fabric.
The Cisco 12016E-CSC is an 80Gbps Enhanced Clock Scheduler Card designed to deliver precise timing and hardware-based traffic scheduling for the Cisco 12016 router.
Key features include 80Gbps scheduling capacity, programmable time-slot allocation, sub-microsecond clock distribution, low-latency traffic shaping, and burst-tolerance over the Cisco 12016 backplane.
By enforcing QoS at line rate, minimizing jitter, reducing latency, and ensuring stable timing, the 12016E-CSC boosts throughput for voice, video, and mission-critical data.
The 12016E-CSC is compatible with Cisco 12016 Modular Routers running IOS 15.x or later and equipped with a Supervisor Engine 720 or newer.
Power down the chassis, insert the card into an available CSC slot, secure it with retention screws, power up the router, and enable scheduling via the IOS CLI.
Yes. The 12016E-CSC supports hot-swapping, allowing insertion or removal without interrupting existing traffic or requiring a chassis reboot.
The card draws approximately 15W. Ensure your Cisco 12016 power supplies meet the combined load and operate within 0°C to 45°C ambient temperature.
Use Cisco IOS CLI: define class-maps, policy-maps, and then apply service-policies on interfaces. The scheduler automatically enforces defined policies.
Yes. It supports hierarchical scheduling, traffic policing, shaping, priority queuing, and Cisco’s NBAR protocol awareness for granular traffic control.
It ships with Cisco’s one-year limited hardware warranty. Optional 24/7 Cisco TAC support and extended service contracts are available for purchase.
Use the Cisco IOS 'archive download-sw' command to upload the latest scheduler firmware file via TFTP or USB, then reload the scheduler module.
The enhanced card doubles scheduling capacity from 40Gbps to 80Gbps and offers tighter clock synchronization accuracy for high-performance applications.
Ideal for real-time voice/video conferencing, high-speed data aggregation, enterprise WAN backbones, and any deployment requiring deterministic packet scheduling.
Order through authorized Cisco resellers or the Cisco Online Store. Volume discounts, support bundles, and licensing options may apply.
Run 'show scheduler statistics' and 'show controllers csc' to verify status. Check cabling, slot seating, IOS compatibility, and firmware versions.
Yes. Its 80Gbps capacity and precise timing make it ideal for high-density cores and data centers demanding low-latency, high-throughput scheduling.
