MGS3750-28F

24-port GbE L2 Switch with Four 10G SFP+ Uplink Ports

The Zyxel MGS3750-28F 24-port GbE L2 Switch with four 10G SFP+ Uplinks
has been 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 different
needs for Metro Ethernet services.

Benefits

Carrier Ethernet services

Carrier Ethernet technology employed in the Zyxel MGS3750-28F 24-port
GbE L2 Switch with four 10G SFP+ Uplink refers to the utilization of high­bandwidth Ethernet technology in Internet access as well as in government,
business and academic LAN communications. Carrier Ethernet employs
hardware and software to improve connectivity, along with maintenance

and management services beyond standard Ethernet
to offer performance carrier-grade network transport
protocols that are ideal for Metropolitan Area Networks
(MAN) as well as WAN. It also enjoys quick fault recovery
generally engineered for carrier-grade systems. IP traffics
have significant increased by about five-folds over the
years, and it is bound to continue at the same pace in the
following years. The need for higher bandwidth from the
increasing use of mobile broadband and other wireless
technologies is a major factor entailing the demand for
scalable network infrastructures such as carrier Ethernet
equipment.

Enhanced security to protect customers

Avoiding subscribers to affect each other on a shared
network or device is a major concern for service providers.
The Zyxel MGS3750-28F offers a complete set of security
features to protect user data while looking over the traffics.

The intrusion lock function detects the “plugged”
and “unplugged” status change of Ethernet cables to
deactivate a specific port automatically if needed. The

802.1x authentication can secure the network from
unauthorized users, while Port Security provides the ability
to deny unauthorized users from accessing the network.

Moreover, the 802.1x feature, in collaboration with RADIUS,
is useful on preventing unauthorized access based on
username and password (or other credentials) and it also
acts as a powerful access controller for networks with
mixed wired and wireless converge. The MGS3750-28F
provides a multi-layer (L2/L3/L4) ACL suite of sophisticated
policy-based control mechanisms to enables service
providers to easily deploy networks based on actual
environment needs as well as to prevent abnormal or illegal
access via a Web GUI or command line interface. The
policies can be defined to deny packets based on source/
destination MAC addresses, IP addresses or TCP/UDP ports.

Resilient, fail-safe design

Quick recovery and round-the-clock availability is vital for
service providers to establish a robust network. The Zyxel
MGS3750-28F provides comprehensive features to assure
the required network availability.

The IEEE 802.3ad Link Aggregation feature reduces
network downtime by providing redundant paths and
bandwidth aggregation to critical connections, while the
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.

Carrier switches supports DDMI SFP

The enhanced digital interface allows real-time access
to device operating parameters, and it 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 Diagnostics Monitoring Interface (DDMI) enables
users with the capability to perform component monitoring,
fault isolation and failure prediction tasks on their
transceiver-based applications.
