The Huawei S310-48T4S switch connects devices through 48 Gigabit Ethernet ports and features 4 SFP slots. It supports iStack virtual stacking, as well as STP, RSTP, MSTP, ERPS and Smart Link for redundant connections. It can be managed through the Web UI, CLI, SNMP, the cloud or the eKit app.

For traffic control, it supports QoS, per-port rate limiting and eight queues per port with different scheduling algorithms. It also includes DHCP Snooping and ARP logging, while its active cooling system automatically adjusts the fan speed.
