Overview
SMC’s TigerStack™ 100 is a stackable switch with 24 100BASE-FX MT-RJ
ports, plus two slots for optional slide-in 100BASE-FX or 1000BASE-X
modules. One of these slots can also be used for an optional stacking
module that allows you attach up to four switches to a 9.6 Gbps high-speed
backplane. There is also an SNMP-based Network Management Module
installed in the rear panel. This module supports both in-band and
out-of-band access for managing the switch and the attached stack.
Note:
A switch stack, or a switch in a standalone configuration, must have
Network Management Module installed to enable all ports. The base
unit alone has all ports disabled by default.

Switch Architecture
The TigerStack employs a high-speed switching fabric. This design allows
for simultaneous transport of multiple packets at low latency on all ports. It
also uses store-and-forward switching to ensure maximum data integrity. In
this mode, the entire packet must be received into a port buffer and checked
for validity before being forwarded. This prevents errors from being
propagated throughout the network. This switch also features full-duplex
capability on all ports, which effectively doubles the bandwidth of each
connection.
This TigerStack can be used in a standalone configuration, or can be stacked
up to four high to form a single logical switch with up to 104 ports. When
stacked, the 9.6 Gbps stack backplane provides enough bandwidth for the
most demanding environment. Moreover, you can use a 100 Mbps
single-mode fiber module for connecting to a remote site, or a Gigabit
module for a high-speed backbone connection.

This switch contains a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a Network
Management Module that allows the entire stack to be managed in-band
via SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web
browser, or remotely via Telnet. The switch also provides a serial port on
the rear panel for out-of-band management.
Note: Only one Network Management Module must be installed in the
stack for the current firmware release.
Description of Hardware
100BASE-FX MT-RJ Ports
These ports are MT-RJ multimode fiber ports that can be connected to
workstations and servers with 62.5/125 micron or 50/125 micron
multimode fiber cable.
Each of these ports support half- and full-duplex operation at 100 Mbps.
Note that 100BASE-FX ports do not support auto-negotiation of duplex
mode, so this has to be configured manually. However, the ports do
support IEEE 802.3x auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.

Network Management Module

Figure 1-5. Network Management Module
This switch includes a Network Management Module on the rear panel.
This module can manage the switch and the attached stack. It offers a
variety of management options, including SNMP, RMON and a
Web-based interface. This module also includes an RS-232 port 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 null modem cable. This allows you
to access the out-of-band interface. (See Apendix B for a description of
wiring options.)
The Network Management Module provides a wide range of advanced
performance-enhancing features. Multicast filtering provides support for
real-time network applications. Port-based and tagged VLANs provide
traffic security and efficient use of network bandwidth. QoS priority
queueing ensures the minimum delay for
across the network. Flow control
bottlenecks caused by port saturation. And 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 TigerStack 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, this 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.
VLANs
The TigerStack 100 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:
• Eliminate broadcast storms which severely degrade performance in a
flat network.
100
• Simplify network management for node changes/moves by remotely
configuring VLAN membership for any port, rather than having to
manually change the node’s connection.
• Provides 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.
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 802.1p and 802.1Q tags to prioritize
incoming traffic based on input from the end-station application. These
functions can be used to provide independent priorities for delay-sensitive
data and best-effort data.
