L2 Managed Gigabit Ethernet

Switches with (2) Dual-Media SFP Ports.

Available with 8, 16, or 24 10-/100-/1000-Mbps copper ports,
these Layer 2 manageable switches offer advantages in mixed­speed and legacy-integration environments because all LAN
ports support 10BASE-T, Fast Ethernet, and Gigabit Ethernet.
The ports automatically sense the speed of each connected
device, so when you upgrade to high-speed network devices,
the switch automatically keeps pace.

The 8-port switch is an excellent choice for connecting branch
office machines to a larger MAN or WAN. Because it has a noise­free, fanless design and a compact chassis, it’s tailor-made for
cramped SOHOs.

The 16- and 24-port models are ideal for use in workgroups
or WANs and are enclosed in a fan-cooled 1U rackmount chassis.

Dual-media SFP ports for extra versatility

Two ports on each switch are dual-media ports with two
connectors each—one RJ-45 Ethernet and one SFP. You can use
a dual-media port as an ordinary 10-/100-/1000-Mbps copper
Ethernet port or you can use it to plug in an SFP in order to
create a single- or multimode fiber link that supports distances
of up to 20 kilometers (12.4 miles).

Choose 1250-Mbps SFPs for Gigabit Ethernet; use 155-Mbps
SFPs for 10- or 100-Mbps Ethernet. All SFPs report basic link
characteristics such as SFP type, length of fiber link, wavelength,
and bit rate. Models with extended diagnostics also report
information such as temperature, TX and RX power, voltage,
and bias current. The hot-pluggable interface enables you to
change SFPs on the fly when your network requirements
change.

Double up for bandwidth

Port trunking enables you to provide more bandwidth to
a specific application or segment. 802.3ad Link Aggregate
Control Protocol (LACP) bandwidth aggregation lets you
combine Gigabit ports to create a multilink trunk for load
sharing.

The 8-port model supports up to 4 Gigabit ports per trunk
for a bandwidth up to 8 Gbps. The 16-port model can be set
up with up to 8 Gigabit ports per trunk for bandwidth
of up to 16 Gbps. The 24-port model supports up to 12
Gigabit ports per a trunk for up to 24-Gbps bandwidth.

LACP not only increases link capacity, it also creates
higher availability. And because the switches aggregate all
traffic based on MAC addresses, they balance traffic loads
efficiently.

Manage traffic flow

Along with Layer 2 802.1p Priority Queue control, the
switches offer Quality of Service (QoS) support, so you can
program a higher layer classification and ensure that traffic
in real-time applications, such as Voice over IP (VoIP),
receives higher priority.

Broadcast/multicast storm suppression enables you to
restrict excess traffic on your network. You can also control
the rate limit for each switch port and set threshold values
for the size of discarded packets. Jumbo frame support helps
to ensure reliable data transmission, too. With this, you can
set the switches to forward packets up to 9K in size before
discarding them.

Highly secure

The switches also contain a number of security capabilities,
including a Q-in-Q VLAN feature to isolate traffic between
different users, and 802.1x user authentication, which prevents
unauthorized access over the network.

In addition, with VLAN support for advanced 802.1Q,
the switch enables you to limit broadcast traffic to within
the same VLAN broadcast domain. And because the switches
support Generic Attribute Registration Protocol (GARP) and
Generic VLAN Registration Protocol (GVRP), they allow for a
more efficient exchange of VLAN configuration data with
other users and devices.

You can also limit the number of MAC addresses assigned
to each port, which, in turn, enables you to control the number
of access stations for each port. This way, you not only establish

an access mechanism by user and machine, you also control
the number of access stations on your network.

Highly manageable

Monitor, configure, and control ports with ease.
The switches support SNMP, Web-based management,
and CLI management interfaces. You can also stack up to
16 of the switches and, using Virtual Stacking Management
(VSM), manage them all via one IP address. In this
configuration, the switches are seen as part of a logically
segmented VLAN—an expanded network that doesn’t
require the expense or configuration of additional hardware
to implement.

Error resistant

L2 Managed Gigabit Ethernet Switches with (2) Dual­Media SFP Ports also feature extensive error-tracking
capabilities. Port mirroring, for instance, helps you track
errors or abnormal packet transmission—all without inter­rupting data flow in your networked switched environment.

For mission-critical applications, use multiple switches and
configure each with a redundant backup bridge path. Then,
if a failure occurs on one switch, you’ll still be able to
guarantee the transmission and reception of packets via a
secondary link on your network. For proper load balancing in
VLAN applications, the 1000BASE-TX L2 Managed Ethernet
Switch with Dual-Media SFP Ports uses an 802.1w Rapid
Spanning Tree (RST) algorithm for creating a loop-free Layer 2
topology.
