Description
ZYXEL 24-port GbE L2 Copper Switch – 28 Ports – Manageable – 2 Layer Supported – Modular – 4 SFP Slots – Optical Fiber
Twisted Pair W/4 COMBO GBE/FE ACW/BPSDC12V TELCO
The MGS3520 Series GbE L2 Managed Switch is specially designed for service providers to deliver profitable Ethernet services. With the high-performance hardware platform
service providers can easily extend network topologies while enabling robust security
QoS and management functions to help customers fulfilling differentiated needs for Metro Ethernet services.
Benefits
Advanced QoS for significant services
Consistent service quality and reliable connecting ability in a converged network is the key for service providers to win customers and build loyalty; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The MGS3520 Series offers wire-speed flow control that classifies and prioritizes the incoming packets according to the predefine QoS policies that meet requirements of service providers.
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 MGS3520 Series provides 8 priority queues per port for different types of traffics
allowing service providers to set rule-based rate limitations that take full advantage of constrained network resources and guarantee the best performance.
Enhanced security for protection among customers
Avoiding subscribers affecting each other on a shared network or shared device is a major concern for service providers. The MGS3520 Series 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 MGS3520 Series provides a multilayer (L2/L3/L4) ACL suite of sophisticated policy-based control mechanisms that enables service providers to deploy easily based on actual network environment needs via a Web GUI or command line interface to prevent abnormal or illegal access. The policies 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 service providers to establish a robust network. The MGS3520 Series 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 MGS3520 Series supports backup power system
the power is supplied to the switch in case of an unexpected outage.
