The Huawei CloudEngine S310-48T4S is a next-generation gigabit Ethernet switch designed for enterprise access and high-performance networking. Featuring 48 10/100/1000BASE-T ports and 4 dedicated Gigabit SFP uplink ports, this switch delivers robust connectivity, advanced security, and flexible networking for growing digital infrastructures. With support for Layer 3 routing, intelligent redundancy protocols, and comprehensive DoS defense mechanisms, it offers enterprise-grade performance ideal for campus access and desktop gigabit connections.

Product Features

Flexible Ethernet networking

The CloudEngine S310-48T4S supports a wide array of Ethernet redundancy protocols, including STP, RSTP, MSTP, and Huawei’s own Smart Ethernet Protection (SEP). It also features Ethernet Ring Protection Switching (ERPS), compliant with ITU-T G.8032, offering sub-50ms failover capabilities. These technologies ensure high network availability and rapid recovery from faults.

Intelligent link backup

Smart Link technology allows the switch to connect to multiple upstream aggregation switches, supporting active/standby uplinks for enhanced access reliability. This eliminates single points of failure and strengthens network resilience.

Advanced security control

The switch supports 802.1X, MAC address-based authentication, and hybrid authentication modes. Administrators can enforce dynamic policies such as VLAN assignment, QoS, and ACL configurations per user session. These features help secure access and enforce role-based network segmentation.

DoS and spoofing protection

To safeguard against common network threats, the switch includes protections against SYN flood, Smurf, and ICMP flood attacks. It also blocks DHCP spoofing, IP/MAC spoofing, and malformed DHCP packets through DHCP snooping and binding validation.

Secure DHCP management

With support for trusted and untrusted DHCP ports, DHCP snooping, and binding tables, the switch enforces secure IP address assignment and prevents unauthorized DHCP servers from disrupting the network.

ARP security

Strict ARP learning mechanisms protect against spoofing and exhaustion attacks, ensuring that only verified entries are added to the ARP table. This maintains stable and secure Internet access for authorized users.

Intelligent cooling and robust design

Built with a high-efficiency fan and intelligent temperature control, the switch maintains safe operation in environments ranging from -5°C to +50°C. It supports high-altitude deployment up to 5000 meters and operates quietly at an acoustic pressure of 34.6 dB(A).
