S5720-SI Series Switches

Flexible Gigabit Ethernet switches that provide resilient, high-density Layer 3 switching for data centers. Features include multiple-terminals, HD video security, and video conferencing applications. Intelligent iStack clustering, 10 Gbit/s upstream ports and IPv6 forwarding enable use as aggregation switches in enterprise campus networks.

Next-generation reliability, security, and energy-saving technologies make S5720-SI Series Switches easy to install and maintain, and an excellent source of low Total Cost of Ownership (TCO).

Automatic Service Provisioning


Layer 3 features such as OSPF, IS-IS, BGP, and VRRP provide services such as voice, video, and data.

Ultra-High Bandwidth

iStack Properties

Intelligent Stack (iStack) virtualizes multiple switches into one, improving device reliability, simplifying configuration and management, and providing configuration-free stacking.

Network Operation Mode

SVF for Ultra-Simplified Network O&M

Huawei’s Super Virtual Fabric (SVF) virtualizes the campus network architecture of ‘Core/Aggregation Switches + Access Switches + APs’ into a single network element for simplified network O&M. The S5720-SI also can work as an SVF plug-and-play client.
