Does this DC model retain Virtual Chassis support?
Yes. It supports up to four switches operating together under Virtual Chassis management.
Do I need a license key for base features?
No. The DC-AFO runs the standard software as shipped, and the optional license tiers are listed in Support & Licensing above.
