Features

- Enables long-distance stacking via 10G SFP+ optics
- Simple deployment for distributed closets and campuses
- Maintains single control plane across remote members
- Flexible media options: fiber or DAC/AOC

FAQs

Q: Can this module stack directly with standard FlexStack-Plus copper ports?
A: FlexStack-Extended links operate over SFP+ fiber/DAC. To bridge a local FlexStack-Plus stack to a remote switch, use a Hybrid module on the bridging member or another Extended module on the remote member.

Q: What optics are supported?
A: Standard 10G SFP+ modules such as 10GBASE-SR for multimode and 10GBASE-LR for single-mode, as well as supported 10G DAC/AOC cables.

Q: Is this compatible with Catalyst 2960-S?
A: No. 2960-S uses FlexStack, while 2960-X/2960-XR use FlexStack-Plus/Extended families.

Q: Does it include SFP+ transceivers or cables?
A: Transceivers and DAC/AOC cables are typically sold separately.
