Model: LNK-4048G
Overview
High-performance of both hardware and software
This 10G PoE switch uses top-rated 10G network switching chip,
multiple layers PCB design, as well as self-developed switch
software system. With combination of hardware and software, it
improves product quality from forwarding stability, packet
processing speed, and other work capability.
Support the fast ring network protocol, free configuration
The switch supports stable and reliable fast Ring Protection
Protocol(RSTP). It Achieved real ring loop redundancy protection.
Besides, there is no need to configure 10G port when users using
this switch, to reduce probability of network failure.
Strong network security
Support dynamic or static binding by users’ definition, such as IP,
MAC, VLAN, PORT, etc. Support port isolation, to prevent
communication between two neighbor network equipment within the
same broadcast domain , for reducing network risk; Supports perfect
storm control function which can suppress broadcast, multi-cast,
and uni-cast storm; Support specific ARP inspection which can
effectively prevent ‘‘ARP spoofing attack’’ created by hackers or
attackers via ARP packets.
Convenient management and maintenance
By easy WEB interface(http and https protocol supported), you can
conveniently operate and configure all kinds of function in this
switch. Support management by CLI, Telnet, Console port, which is
more suitable for professional network administrator; It also allow
reset by one-press, making maintenance easier.
