ZyXEL Communications GS-1548 User manual

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.

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
