Switch 48p 1000M, UL 2p 10G, 2p SFP 10G, Layer 3

Strong Business Process Capability

Support RIP (Routing Information Protocol) and OSPF (Open Shortest Path First), solving the routing problem of large and medium complex networks after subnet subdivision and simplify network configuration.
Support static route, administrators can manually configure router numbers to realize the communication between network segments in a simple, efficient and reliable way.
Support DHCP server, assigning IP address for host.
Support DHCP relay, it can obtain IP address through different ports or switches in different subnets, and reduce the numbers of DHCP server.
Support proxy ARP to realize the communication between the hosts of different physical networks in the same network segment.
Support 802.1Q-based VLAN, MAC-based VLAN, VLAN & Private VLAN, administrators can flexibly assign VLAN.
Support GVRP to realize the function of dynamic distribution, register and propagation for VLAN. And it reduces manual configuration to ensure correct configuration.
Support VLAN-VPN, through this function, the switch would encapsulate two Layers of VLAN tag on private network messages before getting them through the public network.
Support QoS of Port-based, 802.1P-based and DSCP-based, with EQU & WRR etc. scheduling for priority queues.
Support ACL, configuring matching rules, processing operations and time permissions to filter packets to provide security access control policy.
Support IGMP V2/V3 Snooping & MLD Snooping, meeting the access requirement of multi-terminal for HD video surveillance and video conference.

Excellent Security Mechanism

Support IP+MAC+VLAN+port binding.
Support ARP protection against ARP spoofing & ARP flooding.
Support IP Source Guard, protecting the system from MAC spoofing, IP spoofing and counterfeiting IP/MAC address.
Support DoS protection against Land Attack, Scan SYNFIN, Xmascan & Ping Flooding etc.
Support 802.1X authentication. It can control the authorization status of the port according to result of authentication.
Support Port Security, it would stop learning when the learning number reached the maximum. And it prevents MAC address attack and controls network traffic of port.
Support DHCP Snooping, which effectively puts an end to setting up DHCP server privately, and ensures the validity of DHCP server.

Multiple Reliable Protection

Stacking technology, connect with stack member via 10G port, simplifies management and improves reliability of system.
Support Spanning Tree Protocol - IEEE 802.1D Classic Spanning Tree Protocol (STP)- IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)- IEEE 802.1s Multiple Spanning Tree Protocol (MSTP).
Support static aggregation and dynamic aggregation, effectively increasing link bandwidth, and realizing load balancing & link backup, and improving link reliability.
Support redundant power supply to ensure continuous operation (UTP7748GE-L3).

Simple Maintenance

Support WEB Management, CLI Command (Console, Telnet) & SNMP (V1/V2/V3) etc.
Support encryption of HTTPS, SSL V3, TLSV1, SSHV1/V2.
Support RMON, Syslog, convenient for network optimization and transformation.
Support LLDP. It is convenient for administrators to check and judge the communication status of the link through the network management system.
Support CPU monitoring, memory monitoring, PING, Tracert, cable inspection.
