Tanımlama:

The DGS-3130-30S Layer 3 Stackable Managed Switches are a range of switches designed for
Small Medium Businesses (SMBs), Small Medium Enterprises (SMEs), enterprises, and ISPs. They
deliver high performance, flexibility, fault tolerance, and advanced software features for
maximum return on investment. With Gigabit Ethernet SFP, 10GBase-T and 10 GbE SFP+,
security features, and advanced Quality of Service (QoS), the DGS-3130-30S Series can act as
core, distribution or access layer switches. High port densities, switch stacking, and easy
management make the DGS-3130-30S suitable for a variety of applications.


Standard, Enhanced and Routed Images
The DGS-3130-30S has support for three different software images - the Standard Image
(SI), Enhanced Image (EI), and Routed Image (RI). The Standard Image provides
sophisticated features for campus or enterprise usage. It includes advanced Quality of
Service (QoS), traffic shaping, L2 multicasting, robust security features, and IPv6 features
which are suitable for next-generation IPv6 networks or triple play applications over Metro
Ethernet. The Enhanced Image supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static
Route, IMPB, and sFlow. The Routed Image supports DHCP Server, VRRP, IPv6 Tunneling, RIP,
OSPF, IGMP, MLD, PIM, and DVMRPv3.

Enhanced Network Reliability
The DGS-3130-30S targets enterprises, campuses, and customers who require
a high level of network security and maximum uptime. The models in the
DGS-3130-30S support an external redundant power supply so that
continued operation can be assured. They also include other features, such
as 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP), and
802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and
Broadcast Storm Control, that enhances network resilience. G.8032 Ethernet
Ring Protection Switching (ERPS)2 minimizes the recovery time to 50 ms.
For load sharing and redundancy backup in a switch cascading/server
attachment configuration, the DGS-3130-30S provides dynamic 802.3ad Link
Aggregation Port Trunking.


Comprehensive Security
The DGS-3130-30S provides users with the latest security features such as
Multi-layer and Packet Content Access Control Lists (ACL), Storm Control,
and IP-MAC-Port Binding (IMPB)2 with DHCP Snooping. The IP-MAC-Port
Binding feature allows administrators to bind a source IP address with an
associated MAC and also define the port number to enhance user access
control. With the DHCP Snooping feature, the switch automatically learns
IP/MAC pairs by snooping DHCP packets and saving them to the IMPB
white list. In addition, the D-Link Safeguard Engine identifies and prioritizes
“CPU interested” packets to prevent malicious traffic from interrupting
normal network flows, and to protect switch operation


Identity Driven Network Policies

The DGS-3130-30S supports authentication mechanisms such as 802.1X, Webbased
Access Control (WAC), and MAC-based Access Control (MAC) for
strict access control and easy deployment. After authentication, individual
policies such as VLAN membership, QoS policies, and ACL rules can be
assigned to each host. In addition, the switch also supports Microsoft® NAP
(Network Access Protection). NAP is a policy enforcement technology that
allows customers to protect network assets from compromised computers by
enforcing compliance with network health policies.
Traffic Management for Triple Play
The DGS-3130-30S implements a rich set of multilayer QoS/CoS features to
ensure that critical network services such as VoIP, video conferencing,
IPTV, and IP surveillance are given high priority. Traffic Shaping features
guarantee bandwidth for these services when the network is busy. L2
Multicast support enables the DGS-3130-30S to handle growing IPTV
applications. Host-based IGMP/MLD Snooping allows multiple multicast
subscribers per physical interface and ISM VLAN to send multicast streams in
a multicast VLAN to save bandwidth
and to provide better security to the backbone network. The ISM VLAN profiles
allow users to bind/replace the pre-defined multicast registration information
to subscriber ports quickly and easily.
Proactive, Effective Network Management
To uphold enterprise customers’ Service Level Agreements (SLA), service
providers must reduce their Mean Time to Repair (MTTR) and increase service
availability. Ethernet OAM features address these challenges and
enable service providers to offer carrier-grade services. The DGS-3130-30S
supports industry-standard OAM tools, including IEEE 802.3ah, IEEE802.1ag,
and ITU-T Y.1731. Connectivity Fault Management (CFM) provides tools to
monitor and troubleshoot end-to-end Ethernet networks, allowing service
providers to check connectivity, isolate network issues, and identify
customers affected by network issues.


IPv6 Technology
The DGS-3130-30S is fully compliant with future IPv6 networks. It supports
remote IPv6 manageability from Telnet, HTTP, or SNMP. To create secure
IPv6 networks, the DGS-3130-30S uses IPv6 ACL, DHCPv6 Snooping, and
Neighbor Discovery (ND) Snooping functions to protect the network from
illegal IPv6 clients. The DGS-3130-30S has been certified with IPv6 Ready
Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium.
The IPv6 Ready Logo Program ensures the conformance and interoperability
of IPv6 products.


Green Technology
D-Link is striving to take the lead in developing innovative and power-saving
technology that does not sacrifice operational performance or
functionality. The DGS-3130-30S implements the D-Link Green Technology,
which includes a power saving mode, Smart Fan, reduced heat, and cable
length detection. The power-saving feature automatically powers down
ports that have no link or link partner. The Smart Fan feature enables the
built-in fans to automatically turn on at a certain temperature, providing
continuous, reliable, and ecofriendly operation of the switch. Energy
Efficient Ethernet (EEE) standard is also supported, which helps to reduce
the operating cost of the DGS-3130-30S.

Manageability
D-Link’s Single IP Management (SIM) simplifies a nd s peeds up management
tasks, allowing multiple switches to be configured, monitored, and maintained
from any workstation running a web browser through one unique IP address.
This virtual stack is managed as a single object, having all units maintained by
one IP address. The DGS-3130-30S also supports standard-based management
protocols such as SNMP, RMON, Telnet, Console, Web-based GUI, and SSH/
SSL security authentication
