ZyXEL Communications GS-1548 Bedienungsanleitung

The Switch 1500 Series with advanced Web-based management support is specially designed

for SME networks where large bandwidth,advanced QoS and security features are required.

Through the Web GUI interface,users can implement rich network management with ease.

The ZyXEL Switch 1500 Series comes in two groups: GS-1500 and ES-1500. The GS-1500 group

of Web-managed switches comes with 20/44 Gigabit copper ports and 4 dual-personality (RJ-

45/SFP) ports, while the ES-1500 group Web-managed switches comes with 24/48 10/100

copper ports, 2 1000Base-T ports and 2 GbE open SFP slots.

Key Benefits

Robust system design for SME network

The ZyXEL GS-1500 Web-managed switch provides 48/96 Gbps of non-blocking connectivity and

the ES-1500 Web-managed switch provides 12.8/17.6 Gbps of non-blocking connectivity for SME

networks.With the flexible multi-function design, GS-1500 and ES-1500 switches fit any network

with very little effort. By utilizing Gigbit uplinks and port aggregation, bandwidth on critical paths

can be expanded flexibly by merging multiple traffic pipelines into a logical one to dramatically

improve network stability.

Evolutionary new managed power

While many legacy Web-based Smart switches improve manageability, configuration complexity is

still an issue. For most SB/Enterprises,inadequate IT expertise and complicated configuration are

major concerns to overcome. Powered by the next-generation hardware platform with a content-

aware engine, the ZyXEL 1500 Series delivers stress-free networking. In addition, the streamlined and

intuitive Web-GUI makes the 1500 Series even easier to configure with much less efforts.

Auto DoS attack prevention

Security is becoming increasingly important in SB/Enterprise networks. Equipped with Auto DoS

Attack Prevention, the ZyXEL 1500 Series is capable of protecting against ubiquitous DoS attacks.

A few mouse clicks are all it takes to initiate the protection, complete the once-complicated ACL

setting and reduce operating efforts dramatically. The 1500 Series supports 802.1Q VLAN for traffic

isolation and Static MAC forwarding as well as dynamic ARP to establish a strictly protected

network.

Auto voip optimization

Migration to VoIP is the key to differentiate business competitiveness. It usually requires IT expertise

to optimize a network for VoIP applications.With emergence of the“Auto VoIP” feature, the 1500

Series can identify VoIP packet patterns and grant the highest priority to automatically establish a

VoIP-friendly communication.The“Auto VoIP”feature offers IP telephony without configuration

headaches; features such as four priority queues and the WRR (Weighted Round Robin) scheduling

algorithm are usually deployed on enterprise networks, allowing users to optimize network

bandwidth usage and implement QoS (quality of service). In terms of bandwidth management and

switch interconnections,users can choose from several options and pick the most appropriate one

with just a mouse click.

Standard Compliance

• IEEE 802.3 10Base-T Ethernet

• IEEE 802.3u 100Base-Tx Ethernet

• IEEE 802.ab 1000Base-T Ethernet

• IEEE 802.3z

• IEEE 802.3x flow control

• IEEE 802.1p class of service, priority protocols

• IEEE 802.1Q VLAN tagging

• IEEE 802.3ad LACP aggregation

Traffic Management and QoS

• Rate limiting: port-based bandwidth control

with 7 grades (64 kbps, 256 kbps, 1 Mbps,

10 Mbps, 64 Mbps, 100 Mbps, 1 Gbps)

• Broadcast storm control

• IEEE 802.1p with 4 hardware priority queues per

port for different traffic types

• WRR (Weighted Round Robin)/SPQ/scheduling

Auto VoIP

• Auto VoIP module explicitly matches VoIP

streams in switches and assign the highest

priority for the following VoIP packets

Auto DoS Attack Prevention

Auto DoS module explicitly matches attack

patterns in switches and prevent network outrage

• Types of DoS attacks can be prevented

- Land attacks: these attacks result from sending

a specially crafted packet to a machine where

the source host IP address is the same as the

destination host IP address.The system

attempts to reply to itself, resulting in system

lockup.

- Blat attack: these switch result from sending a

specially crafted packet to a machine where the

source host port is the same as the destination

host port. The system attempts to reply to itself,

resulting in system lockup.

- SYNFIN scans: SYNchronization (SYN,

ACKnowledgement (ACK) and FINish (FIN)

packets are used to initiate,acknowledge and

conclude TCP/IP communication sessions.The

following scans exploit weakness in the TCP/IP

specification and try to illicit a response from a

host to identify ports for an attack:

Scan SYNFIN: SYN and FIN bits are set in the

packet

Xmascan: TCP sequence number is zero and

the FIN, URG and PSH bits are set

NULL scan: TCP sequence number is zero and

all control bits are zeros

SYN with port <1024: SYN packets with

source port less than 1024

- Smurf attacks: this attack uses Internet Control

Message Protocol (ICMP) echo requests packets

(pings) to cause network congestion or

outrages

- Ping flooding: this attack floods the target

network with ICMP packets

- SYN/SYN-ACK flooding: this attack floods the

target network with SYN or SYN/ACK packets
