Robust System Design
ZyXEL GS-1548 is a 48-port L2 Gigabit switch with advanced
Web-based management support, and it's specially designed
for SMB/Enterprise networks where extra bandwidth and
advanced QoS or security features are required. To cope
with the diverse requirements of SMB/Enterprise businesses,
the ZyXEL GS-1548 Web-managed switch comes with 40 Gigabit
copper ports plus 4 dual-personality (RJ-45/SFP) Gigabit
ports to provide 96 Gbps of non-blocking connectivity
for SB/SMB networks. With the flexible multi-function
design, GS-1548 fits any network with very little effort.
Evolution New Managed Power
While many legacy Web-based Smart Switches improve manageability,
configuration complexity is still an issue; for most
SB/Enterprise, inadequate IT expertise and complicated
configuration are the major concerns to overcome. Powered
by the next-generation hardware platform with a content-aware
engine, ZyXEL GS-1548 delivers stress-free networking.
In addition, the streamlined and intuitive Web-GUI makes
GS-1548 even easier to configure to slash the efforts
needed.
Auto DoS Attack Prevention
Security is becoming increasingly important in SMB/Enterprise
networks. Equipped with Auto DoS Attack Prevention,
the GS-1548 is capable of protection 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 GS-1548 supports 802.1Q VLAN for traffic isolation,
as well as Static MAC forwarding and 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, however, the GS-1548 can
identify VoIP packet patterns and grant the highest
priority to establish a VoIP-friendly communication
automatically. "Auto VoIP" 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 with
just a mouse click.

Auto DoS attack prevention:
Auto DoS module explicitly matches attack
patterns in switches and prevents network
outage
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 results
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.
