The WS-X6816-10T-2T is perfect for high-performance environments. It offers 16 10T ports, ensuring reliable and high-speed network connectivity.
The WS-X6816-10T-2T is a Cisco Catalyst 6500 line card providing 16 copper 10/100/1000 Ethernet ports with integrated DFC4 for advanced forwarding.
It offers 16 RJ-45 Gigabit Ethernet ports, each supporting 10 Mbps, 100 Mbps and 1 Gbps operation.
Cisco’s Distributed Forwarding Card 4 (DFC4) delivers up to 720 million packets per second (mpps) with wire-speed performance on all 16 ports.
The WS-X6816-10T-2T is compatible with Cisco Catalyst 6503, 6506, 6509 and 6513 chassis running Supervisor 2T or higher.
Power down the chassis, slide the module into an available slot until it seats firmly, secure the latches, then power up for automatic detection.
No, hot-swapping is not supported; you must power down the Catalyst 6500 chassis before insertion or removal.
With DFC4, the module delivers up to 48 Gbps switching capacity and 720 mpps forwarding performance at wire speed.
Yes, it supports Cisco QoS, ACL filtering, NetFlow, and hardware-accelerated IP security (IPsec) features under the appropriate IOS image.
Use Cisco IOS Software Release 12.2(33)SXH or later with Enterprise Services Feature Set for full QoS, security and multicast support.
Run the CLI commands “show module” and “show platform hardware throughput level” to confirm module recognition and DFC4 forwarding status.
