1.2.4 Comprehensive Security Measures
The S3700 guarantees security of network devices and data transmission. It provides the
following security measures to protect a network against attacks initiated by malicious users:
l Comprehensive mechanisms to defend against MAC-based attacks
l Various ACL policies
l Many anti-attack functions such as MAC forced forwarding, IP source guard, ARP security,
and CPU defense
l Mechanism of forwarding table search based on VLAN IDs and MAC addresses
l Traffic suppression
In addition, the S3700 provides the following functions to ensure secure login of users:
l Provides login passwords and password encryption for login users.
l Protects commands through users levels and command levels.
l Locks the configuration terminal through a certain command to prevent illegal use of the
device.
l Displays confirm messages for important commands that affect system performance.
The S3700 provides the Automatic Laser Shutdown (ALS) function, which enables the S3700
to stop transmitting laser when a fiber is broken. This function protects users against the laser.
1.2.5 Convenient Operation and Maintenance
In addition to collecting traffic statistics based on interfaces and VLANs, the S3700 provides
fault detection and location tools such as ping and traceroute on an IP network. It can also work
with the Huawei eSight network management system (NMS) to implement performance
monitoring, alarm report, and fast fault location.
eSight provides various functions to help you manage the S3700, including resource
management, topology management, and configuration file management, batch configuration.
In addition, eSight can show important performance indicators in diagrams and tables to facilitate
device management.
The S3700 supports the Huawei Group Management Protocol (HGMP). Through HGMP, an
S3700 can manage multiple switches by automatically collecting topology information and using
a uniform management channel.
1.2.6 Energy-Saving Design
The S3700 adopts the following measures to save energy:
l The chip switches to the power saving mode when no connected device is detected on a
service interface, that is, the interface is idle.
l It uses highly-integrated and energy-saving chips produced through advanced processing
techniques. With the help of the intelligent device management system, the chips not only
improve system performance but also greatly reduce power consumption of the entire
system.
Natural heat dissipation has the following advantages:
l The product reliability is high.
l There is no noise pollution.
