Switch Architecture

The TigerSwitch 10/100 employs a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets
at low latency on all ports. This switch also features full-duplex capability
on all ports, which effectively doubles the bandwidth of each connection.

Switching Method

The switch uses store-and-forward switching to ensure maximum data
integrity. With store-and-forward switching, the entire packet must be
received into a buffer and checked for validity before being forwarded.
This prevents errors from being propagated throughout the network.

Management Options

This switch contains a comprehensive array of LEDs for “at-a- glance”
monitoring of network and port status. It also includes a built-in network
management agent that allows the switch to be managed in-band using
SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or
remotely via Telnet. The switch provides an RS-232 serial port (DB-9
connector) on the front panel for out-of-band management. A PC may be
connected to this port
null-modem cable. (See Appendix B for wiring options.)

for configuration and monitoring out-of band via a

This switch provides a wide range of advanced performance-enhancing
features. Port-based and tagged VLANs, plus support for automatic
GVRP VLAN registration and IGMP multicast filtering provide traffic
security and efficient use of network bandwidth. QoS priority queueing
ensures the minimum delay for moving real-time multimedia data across
the network. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm control prevents broadcast
traffic storms from engulfing the network. Some of this switch’s advanced
features are described below. For a detailed description, refer to the
Management Guide.

Spanning Tree Protocol

The TigerSwitch 10/100 supports IEEE 802.1D Spanning Tree Protocol.
This protocol adds a level of fault tolerance by allowing two or more
redundant connections to be created between a pair of LAN segments.
When there are multiple physical paths between segments, the protocol
will choose a single path and disable all others to ensure that only one
route exists between any two stations on the network. This prevents the
creation of network loops. However, if the chosen path should fail for any
reason, an alternate path will be activated to maintain the connection.

The default setting for the Spanning Tree Protocol is “enabled.” This
protocol may be configured out-of-band via the serial console port, or
in-band via the Web interface, Telnet, or SNMP network management
software.

VLANs

The TigerSwitch 10/100 supports up to 255 VLANs. A Virtual LAN is a
collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network. By
segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a

flat network.

• Simplify network management for node changes/moves by remotely

configuring VLAN membership for any port, rather than having to
manually change the node’s IP address.

• Provide data security by restricting all traffic to the originating VLAN,

except where a connection is explicitly defined via the switch’s routing
service.

Multicast Switching

Specific multicast traffic can be assigned to its own VLAN to ensure that it
does not interfere with normal network traffic and to guarantee real-time
delivery by setting the required priority level for the designated VLAN.
The switch uses IGMP Snooping and IGMP to manage multicast group
registration.

Traffic Priority

This switch provides Class of Service (CoS) by prioritizing each packet
based on the required level of service, using four distinct queues with
Weighted Round Robin queuing for each port. It uses IEEE 802.1p and

802.1Q tags to prioritize incoming traffic based on input from the
end-station application. Also, the switch provides Layer 3/4 priority
mapping of IP Precedence/DSCP values or IP TCP/UDP port numbers
to the IEEE 802.1p priority tag of each frame. These functions can be
used to provide independent priorities for different types of traffic, such as
delay-sensitive data and best-effort data.

Description of Hardware

10BASE-T/100BASE-TX Ports

These are dual-speed RJ-45 ports. Because all ports on this switch support
automatic MDI/MDI-X operation, you can use straight-through cables for
all network connections to PCs or servers, or to other switches or hubs.
(See“100BASE-TX/10BASE-T Pin Assignments” on page B-3.)

Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can
be selected automatically. If a device connected to one of these ports does
not support auto-negotiation, the communication mode of that port can
be configured manually.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so
the switch can automatically prevent port buffers from becoming
saturated.

1000BASE-T/SFP Ports

These are combo Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on the port, the
associated RJ-45 port is disabled.

The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation,
so you can use straight-through cables for all network connections to PCs
or servers, or to other switches or hubs. (See“1000BASE-T Pin
Assignments” on page B-4.)

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via
non-crossbar switching. This means that it can partition a network more
efficiently than bridges or routers. The switch has, therefore, been
recognized as one of the most important building blocks for today’s
networking technology.

When performance bottlenecks are caused by congestion at the network
access point (such as the network card for a high-volume file server), the
device experiencing congestion (server, power user or hub) can be attached
directly to a switched port. And, by using full-duplex mode, the bandwidth
of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the maximum
distance between end stations is limited. For Ethernet, there may be up to
four hubs between any pair of stations; for Fast Ethernet, the maximum is
two. This is known as the hop count. However, a switch turns the hop
count back to zero, so subdividing the network into smaller and more
manageable segments, and linking them to the larger network by means of
a switch, removes this limitation.

2

A switch can be easily configured in any Ethernet or Fast Ethernet
network to significantly boost bandwidth while using conventional cabling
and network cards.

Sample Applications

The TigerSwitch 10/100 is not only designed to segment your network,
but also to provide a wide range of options in setting up network
connections. Some typical applications are described below.

Collapsed Backbone

The TigerSwitch 10/100 is an excellent choice for mixed Ethernet and
Fast Ethernet installations where significant growth is expected in the near
future. You can easily build on this basic configuration, adding direct full­duplex connections to workstations or servers. When the time comes for
further expansion, just cascade the TigerSwitch to an Ethernet or Fast
Ethernet hub or switch.

In the figure below, the TigerSwitch 10/100 is operating as a collapsed
backbone for a small LAN. It is providing dedicated 20 Mbps full-duplex
connections to workstations and 200 Mbps full-duplex connections to
power users and servers.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type.
A 1000BASE-LX SFP transceiver link can connect to a site up to 5 km
away. This allows the TigerSwitch 100 to serve as a collapsed backbone,
providing direct connectivity for a widespread LAN. A Gigabit SFP
transceiver can also be used for a high-speed connection between floors in
the same building, or to connect to other buildings in a campus setting.

AMPLE APPLICATIONS

Making VLAN Connections

VLANs can be based on port groups, or each data frame can be explicitly
tagged to identify the VLAN group it belongs to. When using port-based
VLANs, ports can either be assigned to one specific group or to all groups.
Port-based VLANs are suitable for small networks. A single switch can be
easily configured to support several VLAN groups for various
organizational entities (such as Finance and Marketing).

When you expand port-based VLANs across several switches, you need to
make a separate connection for each VLAN group. This approach is,
however, inconsistent with the Spanning Tree Protocol, which can easily
segregate ports that belong to the same VLAN. When VLANs cross
separate switches, it is therefore better to use VLAN tagging. This allows
you to assign multiple VLAN groups to the “trunk” ports (that is, tagged
ports) connecting different switches.

PPLICATION NOTES

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as
when a switch is attached to a workstation, server or another switch).
When the switch is connected to a hub, both devices must operate in
half-duplex mode.

2. When a switch is connected to a hub or any kind of shared media,

remember to turn off back pressure to prevent jamming packets from
being propagated thoughout the hub.

3. For network applications that require routing between dissimilar

network types, you can attach the TigerSwitch 10/100 units directly to
a router.

4. As a general rule the length of fiber optic cable for a single switched

link should not exceed:

• Gigabit Ethernet — 550 m (1805 ft) for multimode fiber or 5 km
(16404 ft) for single-mode fiber.

• Fast Ethernet — 2 km (1.24 miles) for multimode fiber or 20 km
(2.43 miles) for single-mode fiber.

However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.

Connecting Network Devices

The TigerSwitch 10/100 is designed to interconnect multiple segments (or
collision domains). It may be connected to network cards in PCs and
servers, or to hubs, switches or routers.

Note: Before connecting cables, you may want to first configure the

Spanning Tree Protocol to avoid network loops. Refer to the
Management Guide for more information.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. For 100BASE-TX connections, Category 5 cable
is required; for 10BASE-T, Category 3, 4 or 5 cable can be used.

4

For 1000BASE-T connections, Category 5 or 5e (recommended) cable is
required with all four wire pairs connected. You should also test the cable
installation for IEEE 802.3ab compliance. See “1000BASE-T Cable
Requirements” on page B-5.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X operation,
so you can use standard straight-through twisted-pair cables to connect to
any other network device (PCs, servers, switches, routers, or hubs).

4-1

M

AKING NETWORK CONNECTIONS

Note: If auto-negotiation is disabled for an RJ-45 port, the auto-MDI/

MDI-X pin signal configuration is also disabled.

See Appendix B for further information on cabling.

Caution: Do not plug a phone jack connector into an RJ-45
port. This will damage the switch. Use only twisted-pair cables
with RJ-45 connectors that conform to FCC standards.

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.

Figure 4-1. Making Twisted-Pair Connections

2. If the device is a network card and the TigerSwitch is in the wiring
closet, attach the other end of the cable segment to a modular wall
outlet that is connected to the wiring closet (see “Wiring Closet
Connections” on the next page). Otherwise, attach the other end to an
available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft)
in length.

Note: When connected to a shared collision domain (such as a hub

with multiple workstations), switch ports must be set to
half-duplex mode and back pressure flow control disabled.

power supply may be defective. In this case, contact SMC Technical
Support for assistance.

Installation

Verify that all system components have been properly installed. If one or
more components appear to be malfunctioning (such as the power cord or
network cabling), test them in an alternate environment where you are sure
that all the other components are functioning properly.

In-Band Access

You can access the management agent in the switch from anywhere within
the attached network using Telnet, a Web browser, or other network
management software such as EliteView. However, you must first
configure the switch with a valid IP address, subnet mask, and default
gateway. If you have trouble establishing a link to the management agent,
check to see if you have a valid network connection. Then verify that you
entered the correct IP address. Also, be sure the port through which you
are connecting to the switch has not been disabled. If it has not been
disabled, then check the network cabling that runs between your remote
location and the switch.

Note: The management agent can accept up to four simultaneous Telnet

sessions. If the maximum number of sessions already exists, an
additional Telnet connection will not be able to log into the
system.

Twisted-Pair Cable and Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port.

Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.

For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be red and the other, red with white stripes. Also,
an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a

specific orientation. (See “Cabling Guidelines” on page 4-1 for
an explanation.)

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered.
Be sure to hold the connectors in the same orientation when attaching the
wires to the pins.

Assignment

Because all ports on this switch support automatic MDI/MDI-X
operation, you can use straight-through cables for all network connections
to PCs or servers, or to other switches or hubs. In straight-through cable,
pins 1, 2, 3, and 6, at one end of the cable, are connected straight through
to pins 1, 2, 3 and 6 at the other end of the cable. The table below shows

the 10BASE-T/100BASE-TX MDI and MDI-X port pinouts.

1000BASE-T Pin Assignments

1000BASE-T ports switch support automatic MDI/MDI-X operation, so
you can use straight-through cables for all network connections to PCs or
servers, or to other switches or hubs.

The table below shows the 1000BASE-T MDI and MDI-X port pinouts.
These ports require that all four pairs of wires be connected. Note that for
1000BASE-T operation, all four pairs of wires are used for both transmit
and receive.

Use 100-ohm Category 5 or 5e unshielded twisted-pair (UTP) or shielded
twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the
length of any twisted-pair connection does not exceed 100 meters (328 feet)

WISTED-PAIR CABLE AND PIN ASSIGNMENTS

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections
should also work for 1000BASE-T, providing that all four wire pairs are
connected. However, it is recommended that for all critical connections, or
any new cable installations, Category 5e (enhanced Category 5) cable
should be used. The Category 5e specification includes test parameters
that are only recommendations for Category 5. Therefore, the first step in
preparing existing Category 5 cabling for running 1000BASE-T is a simple
test of the cable installation to be sure that it complies with the IEEE

802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End
Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing
information is specified in the ANSI/TIA/EIA-TSB-67 standard.
Additionally, cables must also pass test parameters for Return Loss and
Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the
ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission
Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch
cables between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test
parameters for 1000BASE-T, there are basically three measures that can be
applied to try and correct the problem:

1. Replace any Category 5 patch cables with high-performance Category
5e cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.
