Overview

LNK-FS242 Management Gigabit fiber network switch is a L2/L4 Gigabit Managed Fiber Switch with 24 1000M SFP optical ports. The hard ware supports wire-speed switching of the second layer.

Users can set all kinds of functions of the switch through the Ethernet port in WEB. Built-in ARP and DOS defense system can effectively defense the ARP, DOS and various virus attack, moreover, It is also equipped with many powerful features: a comprehensive QoS, spanning tree, a storm suppression, Bandwidth Control, IGMP Snooping, ACL access control, DHCP snooping etc. Very suitable for small and medium-sized enterprises, campus network, and the metropolitan area network aggregation applications.

Features

►ARP defense: the function of MAC address and port binding and MAC address security filtering can effectively defense the ARP attack; DHCP snooping can provide ARP protection for users to obtain the MAC dynamically.

►Qos: support for multiple QOS strategy. Based on the 802.1p priority setting, each port provides eight priority queues. IP-DSCP can be divided into different service levels according to the IP header , to achieve a comprehensive QOS. AUTO VOIP can set the port to the highest priority of the voice signal, improve the voice quality of network IP telephone greatly.

►Spanning Tree: Support the standard of IEEE 802.1d and IEEE 802.1w (Rapid Spanning Tree Protocol) and IEEE802.1s (Multiple Spanning Tree Protocol).

►AUTO DOS: defense the following DOS attack with seven different forms.

►Storm suppression: can be set with the Broadcast, multicast, DLF traffic.

►ACL Access Control: used to control the exchange of the packet from the port, to ensure that the intranet site will not be access to users without authority, while indirectly defend ARP attack.

►IGMP Snooping: Support IGMP version 2 (RFC 2236): IGMP Snooping is used to establish the multicast groups to forward multicast packets to avoid wasting bandwidth when a multicast packet overflow network.

►Support for 802.1x authentication, and to provide users with access to authentication.

►Wire-speed filtering - Storage - forward mode, providing a true non-blocking switching structure.

►Support the function of port mirroring, port gathering, port speed limit.

►Support the port-based VLAN and IEEE802.1Q based on VLAN.

Application

Very suitable for small and medium-sized enterprises, campus network, and the metropolitan area network aggregation applications.
