"List price" is the suggested retail price provided to us by our vendors. We make no representation that a substantial number of these products have been sold or offered for sale at the list price. Actual retail prices in your area may be substantially different. Since we sell products on a national basis, it is not possible to know if our merchandise is sold at list price in any particular location or at any particular time. "You Save" reflects the difference between our price and the vendor provided list price shown on our sites. Since the list price may be different than the actual retail prices in your area, you may not actually realize a savings of this amount.

Manufacturers sometimes ask that retailers not display a price if it drops below a certain amount. The "Click here to see Lowest Price" message indicates that the price of the item is so low that the manufacturer requested that it not be advertised (that is, displayed). In a brick-and-mortar store, you would probably have to ask a salesperson what the price of the product is. At eCOST, by clicking on "Click here to see Lowest Price" you are essentially asking to see the price, at which point we show it to you.

Robust System Design
ZyXEL GS-1548 are 48-port L2 Gigabit switch with advanced Web-based management support, and it's specially designed for SB/Enterprise networks where extra bandwidth and advanced QoS or security features are required. To cope with the diverse requirements of SB/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 SB/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 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.
