SGX3728S is the latest development of Gigabit Layer 3 access switch (modular dual power). It’s the second generation intelligent managed switches designed for networks requiring high performance, high port density, high uplink bandwidth and easy to deploy.SGX3728S switch offers Gigabit connectivity with10/100/1000 autosensing ports and 1G or 10G optical uplink.

■  Various Port Types and Flexible Port Expansion
Switch comes with fixed 4*10G ports The series also provides multiple gigabit ports.

■  Excellent Processing capability
Up to 128Gbps switching capacity and 96Mpps liner filtering and forwarding speed

■  Enhanced Reliability Protection Mechanism
Support CPU packed classification and rate restriction by CPU protection policies, which can prevent against illegal
Packet attacks to CPU and reduce the resource consumption.
Support Rapid Spanning Tree Protocol (RSTP), provide rapid convergence and improved fault-tolerant capacity. The network sable operation and load balance are well guaranteed, also improved the reasonable use network channels and redundant link;
Carrier-class switching power supply, supporting functions to prevent against lightning, overpressure and surging. The device can work normally in bad natural weather and instable voltage environment, suitable for 110~240V voltage.

■  Comprehensive Security Control Policies
Support address authentication based on IP +MAC addresses, 802.1x authentication based on user interfaces, and also support IP ACL, MAC ACL, VLAN ACL and L3 / L4 based ACL, can efficiently defend against ARP attacks and viruses. Besides,the switch can provide comprehensive storm control function by suppress broadcast, multicast, DLF flooding and ICMP flooding. The comprehensive secure controls can efficiently guarantee the real-time effectiveness of all security policies.
It supports strict ARP learning, which prevents ARP spoofing attacks that exhaust ARP entries.It also provides an IP source check to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing.
It supports DHCP snooping, which discards invalid packets that do not match any binding entries,such as ARP spoofing packets and IP spoofing packets. This prevents hackers from using ARP packets to initiate attacks on campus networks. The interface connected to a DHCP server can be configured as a trusted interface to protect the system against bogus DHCP server attacks.

■  Convenient and Quick Management and Maintenance
Adopt simple visual Web-based interface (http / https), which helps users to handle various functions easily and conveniently. 
Support Simple Network Management Protocol (SNMP) that the devices are convenient to configure and manage. Small and medium-sized enterprise customers can centralized manage the switch easily.
Support CLI command line management and telnet, suitable for professional network administrators.
Support SSH2.0 and other encryption, which makes management much more secured.
