48-Port Gigabit Manged Switch With 4*10G SFP+

Specification

Powerful business processing capabilities

• Support IGMP Snooping to meet multi-terminal HD video surveillance and video conferencing access needs
• Support the OSPF dynamic routing protocol, solve the routing problem after large complex network partition subnet, simplifying network configuration
• Supports RIP V1 / V2 dynamic routing protocols, solving the routing problem after small and medium network distribution subnet, simplifies network configuration
• Support static routing, administrators manually configure routing entries, implement communication between different network segments, simple, efficient, and reliable
• Support the agent ARP, so that the host in different physical networks in the same network segment can communicate normally
• Support GVRP, implement VLAN dynamic distribution, registration, and attribute propagation, reduce manual configuration, to ensure correctness
• Support IEEE 802.1Q VLAN, can be based on “Access” “Trunk” and “Hybrid” three port modes, users can be flexible to divide VLAN
• Support QoS, support port, based on 802.1p and DSCP-based three priority patterns and SP, WRR, WFQ four queue scheduling algorithm
• Support ACL L2 (Layer 2) ~ L4 (Layer 4) Packet Filtering Function, enabling the data packet by configuring matching rules, processing operations, and time permissions Filter, providing flexible security access control policies
• Support DHCP server to assign IP addresses for hosts in the network
• Support DHCP Snooping, effectively eliminate private DHCP servers to ensure legality of DHCP servers
• Support for DHCP Option 82 relays, the switch in different interfaces or subnets can also get the IP address, reduce the number of DHCP servers
• Supports DHCP listening, restricting end user ports (non-credit ports) can only send DHCP requests, and discard all other DHCPs from the user port. Packet
• Support IEEE 802.1Q VLAN, Mac VLAN, up to 4094 VLANs, users can flexibly divide VLANs according to different needs
• Rich two-layer multicast features, including static multicast groups and dynamic multicast groups, users quickly leave mechanism

Complete security protection mechanism

• Supports four-element binding of IP address, MAC address, VLAN and port to filter data packets
• Support ARP protection, against common gateway spoofing and man-in-the-middle attacks and other common ARP spoofing and ARP flooding attacks in LAN
• Support IP source protection to prevent illegal address spoofing including MAC spoofing, IP spoofing, MAC/IP spoofing
• Supports defenses such as DOS, distributed denial of service, spoofing, and viruses
• Support 802.1X authentication, provide authentication function for LAN computers, and control the authorization status of controlled ports according to the authentication result
• Support port security and isolation, stop learning when the number of MAC addresses learned by the port reaches the maximum number, prevent MAC address attacks and control port network traffic
• Support loop protection, root bridge protection, TC protection, BPDU protection, BPDU filtering, realize link backup and path optimization
• Support loop loop detection to reduce repeated transmission of broadcast, multicast, and unknown unicast messages by the device, resulting in a waste of network resources and even network paralysis. Effectively prevent loops and ensure the stability and security of the network
• Support port alarms, master port status, and ensure network stability

Diverse reliability protection

• Support STP/RSTP/MSTP Spanning Tree Protocol, eliminate Layer 2 loop and realize link backup
• Support link aggregation, manual aggregation, static aggregation and dynamic aggregation, based on source port, source MAC, destination MAC, source IP, destination IP, source IP port, The method of target IP port can be up to 8 aggregation groups, effectively increasing link bandwidth, realizing load balancing, link backup, and improving link reliability
• Support BPUD bridge nesting protocol, use BPDU to dynamically select root bridge and backup bridge, which can be used to eliminate bridge loop
• Supports ERPS ring network protection. When a link on the Ethernet ring network is disconnected, the communication between each node on the ring network can be quickly restored. Single-ring and multi-ring networking are available, supporting fast Speed ring network (fault self-healing time <50ms)

Loose operation and maintenance

• Support Web network management, CLI command line (Console, Telnet, SSH V1/V2), SNMP (V1/V2/V3) compatible with public MIBS and other diversified management and maintenance
• Support HTTPS, SSH V1/V2, SSL V3 and other encryption methods, making management more secure
• Support RMON, system log, hierarchical warning, support remote log server
• Support LLDP, which is convenient for the network management system to query and judge the communication status of the link
• Support HTTP software upgrade, configuration management
• Support CPU monitoring and memory monitoring
• Support electrical port test, optical module information detection
• Support HTTP, TFTP software upgrade, configuration management
