The S2720-EI is a next-generation access switch that provides flexible 100 Mbit/s, GE access ports, and GE uplink ports.

Building on next-generation, high-performance hardware, and the Huawei Versatile Routing Platform (VRP), the S2720-EI supports intelligent Stack (iStack), flexible Ethernet networking, and diversified security control. It provides customers with a cost-effective 100 Mbit/s or gigabit to the desktop solution.



Diverse types of authentication, iStack, and a range of routing protocols for next-generation switching

  • Support 802.1x authentication, MAC address authentication and Portal authentication

  • Support intelligent Stack (iStack)

  • Support various Layer 3 routing protocols (such as RIP and OSPF), and work as a Super Virtual Fabric (SVF) client that is plug-and-play with zero configuration
