IGERSWITCH

1000

Overview

The TigerSwitch 1000 is a high-performance Gigabit Ethernet
switch designed for the network core. It provides eight 1000 Mbps
ports that can significantly improve the performance of your
network’s backbone, and deliver the throughput needed to
support a broad range of advanced network applications.

With 16 Gigabits of aggregate bandwidth, the TigerSwitch 1000
can provide the quickest solution to meeting the growing demands
on your networkís limited resources. This switch has six
1000BASE-SX SC fiber ports and two GBIC slots. Each 1000 Mbps
port can support high-bandwidth connectivity within or between
workgroups, and increased capacity for server farms, giving your
users faster access to network-wide resources.
The TigerSwitch 1000 includes a built-in management agent that
allows you to configure or monitor the switch using the embedded
management program or SNMP/RMON applications. To manage
the switch, you can make a direct connection to the console port
on the switch’s front panel. You can also make a network
connection to manage the switch using Telnet, the on-board Web
agent, or any SNMP-based network management software.

Description of Hardware

1000BASE-SX Ports

These ports are SC-type fiber optic ports that operate at 1 Gbps full
and half duplex. The ports can be connected to other IEEE

802.3z-compliant devices up to 550 m (1805 ft.) away using fiber
optic cable. The switch is fitted with SC ports, but you can also
attach an ST plug to the switch using SMC’s optional SC-ST
Converter (Part Number: 99-012034-091).

GBIC Slots

The two slots on the switch front panel are for installing optional
5V GBIC transceivers. Note that GBIC transceivers are
hot-swappable. You do not need to power off the switch before
installing or removing a transceiver.

Network Management Agent

The TigerSwitch 1000 includes a built-in network management
agent. The agent offers a variety of management options, including
SNMP, RMON and a Web-based interface. The switch also provides
a serial port on the rear panel for out-of-band management. This is
an RS-232 serial port with a DB-9 connector. A PC may be
connected to this port for configuration and monitoring purposes
out-of band via a full-handshaking null-modem cable. (See
Appendix B for a description of wiring options.)

The network management agent provides a wide range of
advanced performance-enhancing features. Port-based and tagged
VLANs provide traffic security and efficient use of network
bandwidth. QoS priority queueing ensures the minimum delay for
moving real-time multi-media data across the network. Flow
control eliminates the loss of packets due to bottlenecks caused by
port saturation. And broadcast storm suppression prevents
broadcast traffic storms from engulfing the network. Some of the
management features are described below. For a detailed
description, refer to the Management Guide that is included with
the switch.

BOUT THE TIGERSWITCH

Spanning Tree Protocol

The TigerSwitch 1000 supports ANSI/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 (enabled or disabled)
out-of-band via the serial console port or in-band via the Web
interface, Telnet, or SNMP network management software.

VLANs

The TigerSwitch 1000 supports up to 256 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:

1000

• Eliminate broadcast storms which severly degrade performance

in a flat network.

• Simplify network management for node changes/moves by

remotely configuring VLAN membership for the concerned
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 has been configured
between separate VLANs using a router or Layer 3 switch.

BOUT THE TIGERSWITCH

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 Quality of Service (QoS) by prioritizing each
packet based on the required level of service, using two distinct
categories with Weighted Fair Queuing. It uses IEEE 802.1Q and

802.1p tags to prioritize incomming traffic based on input from the
end-station application driver. These functions can be used, for
example, to provide independent priorities for real-time video,
real-time voice, guaranteed-delivery data, or best-effort data.

1000

Optional Redundant Power Unit

SMC provides an optional Redundant Power Unit (RPU),
SMCRPU150W, that can supply power to the switch in the event of
failure of the internal power supply.

Power Supply Receptacles

There are two power receptacles on the rear panel of the switch.
The standard power receptacle is for the AC power cord. The
receptacle labeled “DC Input” is for the optional Redundant Power
Unit (RPU).
