SKU: LK5044XP12C32F Category:

LK5044XP12C32F is a high performance aggregation managed switch, featured 28*100/1000M SFP, 12*10/100/1000M BASE-T and 4*1G/10G SFP+  interfaces. It could meets the metro,data center,  campus and enterprise network requirements.

10Gbps Uplink Capacity for Big Bandwidth Application
10G Ethernet is a big leap in the evolution of Ethernet. The 10G SFP+ slots support dual-speed 10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. It is a cost-effective solution for SMB network to achieve the maximum performance of the 10G networks

Solution for IPv6 Networking
With the IPv6/IPv4 dual stack and other management functions, the LK5000 series is the best choice for IP CCTV surveillance, VoIP and wireless solution providers to develop the IPv6 network. Meanwhile they help the SMBs to upgrade their network infrastructures to the IPv6 era without any extra investment.

Robust Layer 2 Features
The LK5000 series can be programmed for advanced switch management functions, such as port aggregation, Q-in-Q VLAN, Spanning Tree Protocol, QoS, bandwidth control, ERPS IGMP/MLD snooping etc. LK5044XP12C32F allows the operation of a high-speed trunk combining multiple ports.

Powerful Security Functions
LK5044XP12C32F provides a comprehensive access control list (ACL) for enforcing security to the edge. It can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP port number or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based and MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be prevented to ensure user privacy.

Enhanced Security and Traffic Control
LK5044XP12C32F supports DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrator can now construct highly-secure corporate networks with considerably less time and effort than before.

User-friendly Secure Management
For efficient management, the LK5044XP12C32F managed switch series is equipped with console, web and SNMP management interfaces. With management interface, LK5044XP12C32F offers an easy-to-use, platform independent management and configuration facility.LK5044XP12C32F supports SNMP and it can be managed via any management software based on the standard SNMP v1 or v2 Protocol. Meanwhile the LK5044XP12C32F offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, LK5044XP12C32F offers the remotely secure management by supporting SSH, SSL and SNMP v3 connection where the packet content can be encrypted at each session.

Intelligent SFP DDM Function
LK5044XP12C32F support SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
