Intelligent L2 Switches Delivering Resilient Performance, Security and Robust SwitchingAdvanced QoS for significant services
Consistent service quality and reliable connecting ability in a converged network is the key for businesses to sustain the operation or services; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The ZyXEL MGS-3712/MES-3728 offers wire-speed flow control that classifies and prioritizes the incoming packets according to the predefine QoS policies that efficiently facilitates all kinds of applications adopted in businesses.
In terms of classification, the Differentiated Services Code Point (DSCP) field and the 802.1p Class of Service (CoS) field are identified to assess the priority of incoming packets. Classification and reclassification can be based on criteria as specific as rules based on IP, MAC addresses, VLAN ID or TCP/UDP port number. For bandwidth management, the MGS-3712/MES-3728 provides 8 priority queues per port for different types of traffics, allowing businesses to set rule-based rate limitations that take full advantage of constrained network resources and guarantee the best performance.
Enhanced security for robust networks
The MGS-3712/MES-3728 offers a complete set of security features to protect user data while administrating the traffics. The intrusion lock function detects the “plugged” and “unplugged” status change of Ethernet cables, and the switch would deactivate a specific port automatically if needed, and the 802.1X authentication can secure the network from unauthorized users. Port security provides the ability to deny unauthorized users from accessing the network.
Moreover, the 802.1X feature cooperating with RADIUS is useful to prevent unauthorized access based on username and password (or other credentials) and acts as powerful access control for converged networks with mixed wired and wireless access.
The MGS-3712/MES-3728 provides a multilayer (L2/L3/L4) ACL suite of sophisticated rule-based control mechanisms that enables businesses to deploy easily based on actual network environment needs via a Web GUI or command line interface to prevent abnormal or illegal access. The rules can be defined to deny packets based on source and destination MAC addresses, IP addresses or TCP/UDP ports.
Resilient and redundant design
A quick recovery and round-the-clock network is vital for modern networks to establish a robust network. The MGS-3712/MES-3728 provides comprehensive features to make sure network is well operated. The IEEE 802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections, while IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allow immediate recovery from failed connections by sending packets via the backup link. Furthermore, since the MGS-3712/MES-3728 supports backup power system, the power is supplied to the switch in case of an unexpected outage.
Intelligent fan control algorithm for power saving
Fans play an important role in energy consumption since it’s the key to heat dissipation. The MGS-3712/MES-3728 features auto temperature detection and appropriate fan speeds with the Intelligent Fan Control algorithm based on complex mathematics and physics formulas. When the ambient temperature is low, the switch would decrease fan speed to prevent unnecessary power waste from excessive cooling.
Additionally, removable fan modules provide flexibility and high availability, and they solve the noise problem when the modules are approaching the end of their life cycle.
Digital Diagnostics Monitoring Interface (DDMI) supported SFP interface
The enhanced digital interface allows real-time access to device operating parameters, and includes optional digital features such as soft control and monitoring of SFP I/O signals. In addition, it fully incorporates the functionality needed to implement digital alarms and warnings.
The digital diagnostic monitoring interface enables users to have the capability of performing component monitoring, fault isolation and failure prediction tasks on their transceiver-based applications.
