L2 Managed Gigabit Ethernet Switches with
Dual-Media SFP Ports.
Available with 8, 16, 24, or 48 10-/100-/1000-Mbps copper ports,
these Layer 2 manageable switches offer advantages in mixed-speed
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 noise-free, fanless
design and a compact chassis, it’s tailor-made for cramped SOHOs.
The 16-, 24-, and 48-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 or four 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).
The 1250-Mbps SFPs support Gigabit Ethernet and 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
OVERVIEW
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. The 48-port model supports up to 24 Gigabit ports
per trunk for up to 48-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 Dual-Media 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.
Web Smart Gigabit Switches
Web Smart Switches make migrating to Gigabit Ethernet
easy and affordable.
Setup is easy. Just use any Web browser to log onto the built-in
CLI interface to configure or monitor the switch.
All 10-/100-/1000-Mbps copper ports are autosensing for speed
and autonegotiating for duplex. The switches also feature Auto MDI/
MDI-X, which means you never need a crossover cable. Plus, you can
populate the SFP slot with a wide range of Gigabit and WDM uplink
modules.
Tagged and port-based VLAN provides precise control over
network traffic segmentation and broadcast domains with up to four
trunk groups. You also get support for IEEE 802.x flow control for full-
duplex mode and collision-based backpressure for half-duplex mode,
plus Quality of Service (QoS) with a two-level priority queue.
SNMP trap management alerts you instantly when something
goes wrong. Port mirroring helps to track network errors or abnormal
packet transmission.
