The MGS3520 Series GbE L2 Managed Switch is specially designed for service providers to deliver
protable 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 fullling dierentiated needs for Metro Ethernet services.
Benets
Advanced QoS for signicant 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 trac ow and set trac
policy becomes more critical than ever. The MGS3520 Series oers wire-speed ow control that classies
and prioritizes the incoming packets according to the predene QoS policies that meet requirements of
service providers.
In terms of classication, the Dierentiated Services Code Point (DSCP) eld and the 802.1p class
of service (CoS) eld are identied to assess the priority of incoming packets. Classication and
reclassication can be based on criteria as specic 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 dierent types of tracs, 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 aecting each other on a shared network or shared device is a major concern for
service providers. The MGS3520 Series oers a complete set of security features to protect user data
while administrating the tracs. The intrusion lock function detects the “plugged” and “unplugged”
status change of Ethernet cables, and the switch would deactivate a specic 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
dened 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.
Agile trac control for converged networking applications
Design for access layer converged data, video and voice applications, the ZyXEL MGS3520 Series has a rich Layer 2 feature set that can shape the trac
for diverse VoIP, video conference, and IPTV deployment. Supporting L2 multicast and IGMP snooping, the MGS3520 Series can support large IPTV
deployments, which using bandwidth eciently by directing multicast trac to the subscribers only. The Multicast VLAN Registration (MVR) function
ensures better network security by allowing a single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. These
advanced trac control features of the MGS3520 Series provide hotels, businesses, and educational institutions greater agility and more eective trac
management for converged applications of today.
Future-Proof connectivity for evolving networks
The ZyXEL MGS3520 Series helps business and organizations stay ahead and get ready for future IPv6 networks. It supports dual stack (IPv4 and IPv6) and
IPv6 host that allows business and organizations to deploy the MGS3520 switch at the network edge today, and easily migrate to the next-generation
Internet Protocol in the future. With support for IPv6 ACL packet ltering, the MGS3520 L2 Gigabit switch can create secured IPv6 networks that are
protected from illegal IPv6 clients. The MGS3520 Series is designed with a comprehensive set of IPv6 management features that include ICMPv6, neighbor
discovery and DHCPv6 relay, which facilitate the migration to next-generation networking applications without an extensive equipment upgrade.
Optimized design for Metropolitan Area Network (MAN)
The MGS3520 Series adopts the “front access” design for technicians to easily wire and maintain outdoor cabinets. The external alarm input/output block
connects mechanical cabinet parts to the management network and oers better protection to the equipment.
Carrier switches supports Digital Diagnostics Monitoring Interface (DDMI) SFP
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.
DDMI Monitors:
• Temperature
• Supply voltage
• Transmitted bias current
• Transmitted power
• Received power
All features listed above include alarm and warning thresholds
