The Cudy GS2018PS2 managed Layer 2 switch features 16 Gigabit Ethernet ports with PoE+ and 2 SFP slots. The PoE ports support the IEEE 802.3af and IEEE 802.3at standards, with up to 30 W per port and a total power budget of 200 W. For network management, it supports VLAN, QoS, link aggregation, and port mirroring.

Management is available via Web, CLI, SNMP, Telnet, and SSH. The switch also supports DHCP snooping, packet filtering, and protection against DoS attacks and ARP spoofing.
