Gigabit 24-Port SFP Fiber Optic Switches With ACL Access Control ,
DHCP Snooping
Product Overview
24+2 Management gigabit fibre network switches is a second, four
gigabit managed switch, provides 24 SFP optical ports and 2 RJ45
ports. Support the second floor of wire-speed switching hardware.
You can form through the Ethernet port on the switch to WEB to set
various functions. Built-in ARP and DOS defense system, effective
defense ARP, DOS and a variety of variants of viruses, in addition
this switchalso equipped with many powerful features: a
comprehensive QoS, Spanning Tree, a variety of storm suppression,
Bandwidth Control, IGMP Snooping , ACL Access Control, DHCP
Snooping and so on. Very suitable for small and medium enterprises,
campus networks and metropolitan area network aggregation
applications.
• Product Key Features
- ARP Defense:MAC address and MAC address port security binding function and
filtering function can be an effective defense ARP attack; DHCP
Snooping can obtain the MAC address to the dynamic ARP protection
for users.
- QoS:Support multiple QOS policy, based on 802.1p priority settings for
each port provides 8 priority queues; IP-DSCP to IP header
according to different service level classification to achieve a
comprehensive QOS; AUTO VOIP function Set the port to the highest
priority voice signals, greatly improve the network IP telephony
voice quality.
- Spanning Tree:Support IEEE 802.1d, IEEE 802.1w (Rapid Spanning Tree Protocol) and
IEEE 802.1s (Multiple Spanning Tree Protocol) standard.
- AUTO DOS:Can the following seven different forms of DOS attacks for defense
- Land attack:an attacker to send with the same IP source address, IP destination
address of the forged TCP SYN packet of information flow, victims
of the system trying to send a response to his information, the
result is a system disturbance and will be paralyzed or restart
- Blat attacks: the attacker sends the same source port number and destination
port number of forged packets, the victim system attempted to send
a response to his information, the result is a system crash or
reboot.
- Smurf attack:an attacker use the target's camouflage the source address of a
broadcast address to the implementation of ping operation, then all
activities will be to target the host response, leading to network
congestion or disruption.
- Ping flood:using Ping broadcast storms, flooding the target system, so the
system can not respond to legitimate traffic.
- SYN / SYN-ACK flood:using SYN or SYN / ACK packets flood the target system.
- Protection Invalid TCP attacks: to prevent the TCP packet with invalid data caused by flood.
- Ping of Death attack:send out a very large ICMP request packets (a "Ping"), its
intention is to cause the target computer input buffer overflow, so
that the paralysis.
- Storm suppression:Can broadcast, multicast, DLF to set the flow.
- ACL Access Control:Used to control the port and out of the packet to ensure that
certain sites within the network will not be without access to
authorized users, while indirectly played a defense ARP attack
capabilities.
- IGMP Snooping: Support IGMP:Version 2 (RFC 2236): IGMP Snooping is used to overflow when the
multicast packet network, the establishment of a multicast group to
forward multicast packets to avoid the waste of bandwidth.
- Support 802.1x authentication, provide users with access to
certification.
- Wire-speed filtering - Storage - forward mode, providing true
non-blocking switching fabric.
- Support port mirroring, port trunking, port speed limit function.
- Support Port-based VLAN and based IEEE802.1Q the VLAN.
