1. PRODUCT OVERVIEW
Description
This installation and user guide describes the Cabletron Systems
ELS100-8TXUF2 Ethernet switch. This unit is IEEE 802.1D bridging
compliant, and supports eight IEEE 802.3u 100Base-TX Fast Ethernet
ports. Each of the RJ-45 ports can alternatively operate as an IEEE 802.3i
10Base-T port. In addition, the switch also includes one port that supports
Fast Ethernet over fiber (IEEE 802.3u 100Base-FX).
The Cabletron Systems ELS100-8TXUF2 switch automatically learns
end-station addresses from the network and stores them in a Media
Access Control (MAC) address forwarding table. Incoming packets are
then forwarded to the appropriate output port based on the addresses in
the packet. Each port on the switch operates at full Fast Ethernet wire
speed with full address and frame filtering. This switch also supports
advanced features such as flow control and broadcast throttling.
The ELS100-8TXUF2 switch can be conveniently mounted on a desk or
shelf. LEDs on the front panel provide information about the operating
status of the switch. The back panel of the switch contains a connector for
an external power adapter that is provided with the switch.

Feature Summaries
The following summaries provide a brief description of ELS100-8TXUF2
features in areas such as standards compliance, functionality,
performance, and options.
IEEE 802.1D Bridge
The ELS100-8TXUF2 switch is fully compliant with IEEE 802.1D
transparent bridging specifications. An aggregate address table
containing 1K address entries is provided for learning, filtering, and
forwarding. Addresses are automatically learned by the switch.
Frame Buffering and Frame Latency
The ELS100-8TXUF2 switch is a store-and-forward switching device.
Each frame is copied into switch memory before being forwarded to
another port. This method ensures that all forwarded frames conform to a
standard Ethernet frame size and have a correct cyclic redundancy check
(CRC) for data integrity. This switching method prevents bad frames from
traversing the network and using up valuable network bandwidth, as with
cut-through switching technology.
To minimize the possibility of dropping frames on congested ports, the
ELS100-8TXUF2 switch provides 128 KB frame buffer per port. This
buffer space is used to queue packets for transmission on congested
networks. This is an additional advantage over cut-through switching
technology, which drops packets immediately when experiencing
collisions.
Auto-negotiation
Auto-negotiation is a process that permits the switch to automatically
select the operational modes of its ports. Upon first being connected, the
switch detects the speed of the network the port is connected to, either
10Mbps or 100Mbps, and the type of communication setting, half or full
duplex. The port is then automatically set by the switch to operate in the
proper mode without user intervention. It is not required that the network
device being connected to the switch supports auto-negotiation as the
ELS100-8TXUF2 switch automatically adjusts to the network device’s
communication settings.
Broadcast Throttling
The ELS100-8TXUF2 switch has the capability to throttle (or limit) the
flooding of packets through the switch. Broadcast, multicast, and
unknown destination address unicast packets received by the switch are
typically flooded to all ports on the switch. When the number of these
types of packets being forwarded is large, the performance of the switch
in forwarding packets of other types may suffer.
4 Product Overview
ELS100-8TXUF2
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.

Client/Server Network Application
To improve workstation performance in a client/server environment, the
ELS100-8TXUF2 switch can be configured to provide 200 Mbps full
duplex Fast Ethernet connections to servers by connecting each to a
dedicated switch port (Figure 1-4). Users can be accommodated through
connections to hubs, both at 10Mbps and 100Mbps speeds, through
10Mbps switches with 100Mbps uplinks, or through direct connections.
The fiber uplink is available to connect the switch to a remote location,
such as another building floor or a separate building.
The ELS100-8TXUF2 switch can be used in a local backbone application,
connecting network segments together and providing file-server access.
Workgroup hubs are provided with a single connection to the switch while
servers are put on dedicated 100 Mbps ports. Routers and other
networking devices can connect off of the switched backbone as well. The
fiber uplink is available to connect the switch to a remote location, such
as another building floor or a separate building.

APPENDIX B. FLOW CONTROL
Flow control is a mechanism that controls the flow of data in both
directions to prevent data loss, buffer deadlock, overload conditions and
minimizing communications overhead during transmission. Figure B-1
illustrates flow control for both half and full duplex applications.
Figure B-1. Flow Control for Full and Half Duplex Applications
Each port of the switch has a transmit queue which buffers frames to be
sent out on that port. In this example, large amounts of data are being
sent from Workstation A (connected to port X) and other ports on the
switch to Workstation B (connected to port Y).The buffer on port Y starts
filling up with data until it reaches a pre-determined threshold. The packet
which causes the threshold to be exceeded triggers the Flow Control
function on the port from which the packet entered the switch, in this case
port X.
Since port X is configured with Flow Control set to Enabled, the switch
responds by initiating a pause frame (full duplex applications) or back-
pressure mechanism (half duplex applications). The pause frame causes
Workstation A to stop sending packets. After a certain amount of time has
elapsed, determined by a value in the pause frame, Workstation A will
resume sending data. Similarly, the back-pressure mechanism forces
Workstation A to stop sending packets by inducing collisions on port X.
Note that for the full duplex pause frame mechanism to work, the device
connected to the switch port must also support IEEE 802.3x flow control.
The pause frame flow control mechanism supported by the ELS100-
8TXUF2 switch conforms with the IEEE 802.3x specification for full duplex
flow control.
