FAQs for WS-X6816-10G-2TXL:
What is the purpose of the integrated DFC4XL?
The DFC4XL provides distributed forwarding capabilities, offloading tasks from the Supervisor Engine and improving scalability and performance in large enterprise networks.
Which Supervisor Engines are compatible with this module?
It is optimized for use with the Supervisor Engine 2T, but can also work with other supervisors with reduced performance and feature limitations.
What types of transceivers are supported?
The module uses X2 optics and supports various types including SR, LR, ER, LRM, and CX4 for diverse deployment needs.
Can I use this module in a classic Catalyst 6500 chassis?
It is physically compatible, but full performance is achieved only in E-Series chassis with adequate cooling and power capacity.
Does it support VSS (Virtual Switching System)?
Yes, it fully supports VSS when deployed with a compatible Supervisor Engine, enabling active-active chassis-level redundancy.
