H3C Core Layer 3 Switch

H3C Layer 3 core switches are high-performance, modular or fixed switches designed for enterprise and campus networks, offering advanced routing, virtualization, and high-speed uplink capabilities.

Overview of H3C Layer 3 Core Switches

H3C offers a range of Layer 3 core switches suitable for campus aggregation, enterprise core, and data center networks. These switches provide high port density, advanced Layer 3 routing, and enterprise-grade security, supporting both IPv4 and IPv6 dual-stack management .

Key Models

1. H3C S5560X Series

• High-density aggregation switch for campus networks.
