9033029 Product Overview 5
A broadcast cutoff threshold rate has been set in the switch for the
forwarding of broadcast and unknown destination address packets. If the
cutoff rate is exceeded, further packets of these types are dropped. This
capability helps to alleviate broadcast storms, a problem often encountered
in Ethernet networks.
LEDs
The switch port LEDs provide a quick and accurate display of the status
of switch connections. The port LEDs indicate link integrity, speed, and
collisions (for half-duplex connections).
Full Duplex Mode
The full duplex mode of operation on a port can double the throughput of
switch connections. This mode disables the collision detection portion of
the Ethernet Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) protocol allowing for two-way traffic.
Flow Control
Flow control allows you to manage network traffic during congestion
periods and to prevent the loss of packets when port buffer thresholds are
exceeded. Flow control also serves to deny access to additional traffic
that could add to a congestion condition. The ELS100-8TXUF2 switch
supports flow control per the IEEE 802.3x standard. See Appendix C
“Flow Control” for more information on this feature.
Spanning Tree
This product is intended to be used as an end-switch and does not
support spanning tree. There is
no loop detection. The user is cautioned
to understand and avoid configurations that can create a loop.
Application Examples
The exploding popularity of the Internet and of corporate intranets, as well
as new, high-bandwidth desktop applications are driving the demand for
Fast Ethernet. The increase in multimedia traffic and the need to support
legacy protocols alongside new, data intensive applications is driving the
need for network segmentation and traffic prioritization.
The ELS100-8TXUF2 switch is ideal for meeting the needs of today’s high
performance networks. The switch’s low cost makes it attractive and
affordable for dedicated 10/100Mbps connections to the desktop.
