8G + 16SFP Management Gigabit Fiber Optic Switch
型号：LNK-FS168
(1) Land attack: the attacker sends forged TCP SYN packets of information flow with the same source IP address, IP destination address, the victim system tries to send a response information to itself, result in a system disturbance and will be paralyzed or restart.
(2) Blat attack: the attacker sends forged packets with the same source port number and destination port number, the victim system tries to send a response information to itself, result in system crashes or restart.
(3) Smurf attack: the attacker uses spoofed source address of attack target to operate ping process to a broadcast address. Then all the active hosts will response the the target, leading to network congestion or disruption.
(4) Ping flood: flooding the target system by the ping broadcast storms, so that the system can not respond to legitimate correspondence.
Overview
16+8 Management Gigabit fiber network switch is a second, fourth layer gigabit managed switch, provides 810/100M/1000M RJ45 ports and 16 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.
