What are valid specifications for VSF requirements?

The specification that one can daisy-chain up to 10 VSF members is correct. Virtual Switching Framework (VSF) allows for the interconnection of multiple switches to operate as a single virtual switch. This daisy-chaining of up to 10 members provides a scalable solution allowing organizations to expand their network infrastructure seamlessly while managing it as a unified entity. This feature enhances both management simplicity and operational efficiency, as all switches within the VSF can share resources like control plane and data plane properties.

The ability to daisy-chain these switches is pivotal in creating larger, more resilient networks without the need for complex configurations that come with traditional stacking methods. This flexibility ensures that additional switches can be added to the network without significant downtime or complicated setups.

In contrast, while connecting members in a ring topology can be discussed within the context of network design for redundancy, it's not a standard practice for VSF configurations. Similarly, meshing members for redundancy does not necessarily align with how VSF is typically deployed; rather, VSF functions through a hierarchical structure. Lastly, while configuration changes in VSF may sometimes require members to reboot, this aspect is more about operational procedure rather than a foundational specification. Therefore, those other options do not reflect the core valid specification
