Series Series
The ZyXEL Metro Switch 3000 Series consists of four switches: the MGS-3712/MGS-3712F,
MES-3728, and ES-3124F.
The Metro Switch 3000 Series 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.

Key Benefits

Meeting Industry Standards
The Metro Ethernet Forum (MEF) is a global industry alliance comprised of more than 145 active members
representing Carrier Ethernet industry groups. The forum develops technical specifications and
implementation agreements to promote interoperability and deployment of Carrier Ethernet services
worldwide. The Metro Switch 3000 Series is aligned with carrier-class standards for Ethernet Private Line
(EPL), Ethernet Virtual Private Line (EVPL) and Ethernet LAN (E-LAN) of Metro Ethernet Forum (MEF), and the
Series has been certified as MEF-9 and MEF-14 compliant.
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 Metro Switch 3000 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 Metro Switch 3000 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 Metro Switch 3000 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 Metro Switch 3000 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.
