Nereden Alınır

Tanımlama

The DGS-1210/ME Series Metro Ethernet Switches are a family of Ethernet switches ideal
for Metro Ethernet applications. These Metro Ethernet Switches provide 8/16/24/48 copper
connections on upgraded Gigabit Ethernet ports, along with Gigabit SFP ports for improved
uplink bandwidth. Surge protection ensures resilience against unexpected electrical spikes,
while a full suite of security and management features keeps your network safe from internal
and external threats.
Gigabit Performance
The DGS-1210/ME Series all come with 10/100/1000 Mbps Ethernet downlink ports for superior
Gigabit performance for your network. All models offr Gigabit SFP uplink ports and the
DGS-1210-10P/ME , DGS-1210-28P/ME, DGS-1210-52P/ME, and DGS-1210-54MP/ME also
offr Power-over-Ethernet (PoE) so network devices such as PoE IP cameras can be installed in
remote locations without immediate access to power outlets. Simply use an Ethernet cable to
connect to these devices at the deployment location and it can act as a conduit not only for
data, but for power as well.
Effient and Resilient
For mission critical environments, the DGS-1210/ME Series Metro Ethernet Switches support
802.1D 2004 edition, 802.1w, and 802.1s Spanning Tree Protocols (STP). STP allows the switch
to be confiured with a redundant backup bridge path, so transmission and reception of
packets can be guaranteed in emergency situations. The switches also support 802.3ad link
aggregation, which enables multiple ports to be grouped in parallel to form a single port,
increasing bandwidth and redundancy for higher availability. These models feature 802.1p
Quality of Service (QoS), allowing for real-time traff classifiation into Weighted Round Robin
(WRR) and strict priority levels mapped to 8 queues. Packet classifiation is based on TOS, DSCP,
MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type, or user-defied packet content for
flxible confiuration for specifi multimedia applications such as VoIP or IPTV

Security & Authentication
DGS-1210/ME Series Metro Ethernet Switches support 802.1X port-based/
host-based access control, guest VLAN, and RADIUS/TACACS+ authentication
for strict access control over the network. The IP-MAC-Port Binding feature
allows administrators to bind a source IP address with an associated MAC
and also to defie the port number to enhance user access control. The builtin D-Link Safeguard Engine™ protects the CPU from broadcast/multicast/
unicast floding by automatically trapping packets and logging events in
these situations. In addition, the Access Control List (ACL) feature enhances
network security and switch performance.
Management Capabilities
A web-based GUI provides a user-friendly interface and easy management,
and DHCP auto-confiuration gives administrators enhanced management
features, allowing them to save confiuration presets to a TFTP server.
Individual switches can then retrieve their IP addresses from the server and
load the preset confiuration. Support for Link Layer Discovery Protocol
(LLDP) allows a network device to advertise its identity and capabilities on the
local network, which helps businesses better manage their network topology.
Also, each port on these switches supports a cable diagnostic feature that
helps detect cable related problems such as length or cable functionality
issues, so the administrator can quickly identify and fi this problem.
Traffic & Bandwidth Control
Integrated bandwidth control allows network administrators to defie
the throughput levels for each port to manage bandwidth. It provides
minimum granularity of 64 Kbps, ingress control for port and flw-based
bandwidth control. The DGS-1210/ME Series also supports traff control,
which optimizes performance by dropping packets beyond the threshold,
and port mirroring helps administrators facilitate traff diagnostics and track
switch performance. The DGS-1210/ME Series also provides IGMP snooping
with IGMP authentication to prune multicast traff and to optimize network
performance.
Multicast Applications
The DGS-1210/ME Series Metro Ethernet Switches feature a full set of L2
multicast functions, including IGMP snooping, IGMP fitering, fast leave, and
multicast traff confiuration for specifi ports. With L2 multicast support,
the DGS-1210/ME Series is ready and capable of handling growing IPTV
applications. Host-based IGMP/MLD snooping allows for multiple multicast
subscribers per physical interface, and ISM VLAN sends multicast streams in
a multicast VLAN, saving bandwidth on the backbone network. ISM VLAN
profies allow users to bind/replace the predefied multicast registration
information to subscriber ports quickly and easily.
