Flexible Ethernet Networking
In addition to the traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the eKitEngine S220 series switches support the latest Ethernet Ring Protection Switching (ERPS) standard in the industry. ERPS is defined in ITU-T G.8032. It provides millisecond-level protection switching based on traditional MAC Ethernet and bridging operations.

Cloud Management
The Huawei eKit application allows users to configure, monitor, and inspect switches in the cloud, reducing installation and O&M labor costs and lowering network OPEX. The eKitEngine S220 series switches support both cloud management and on-premises management functions.

Differentiated Security Control
The eKitEngine S220 series switches support multiple security authentication functions, including MAC address authentication and 802.1X authentication, and provide dynamic user policies (VLAN, QoS, and ACL). The switches support port-based 802.1X authentication and multi-function authentication.

Smart Upgrade
Based on the Huawei Online Upgrade Platform (HOUP), the eKitEngine S220 series switches support smart upgrades. They obtain the version upgrade path from HOUP and download the new system software. The upgrade process is highly automated as it supports one-click upgrades.
