Limited Warranty Statement: SMC Networks, Inc. (“SMC”) warrants its products to be
free from defects in workmanship and materials, under normal use and service, for the
applicable warranty term. All SMC products carry a standard 90-day limited warranty from
the date of purchase from SMC or its Authorized Reseller. SMC may, at its own discretion,
repair or replace any product not operating as warranted with a similar or functionally
equivalent product, during the applicable warranty term. SMC will endeavor to repair or
replace any product returned under warranty within 30 days of receipt of the product.
The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering
new products within 30 days of purchase from SMC or its Authorized Reseller. Registration
can be accomplished via the enclosed product registration card or online via the SMC Web
site. Failure to register will not affect the standard limited warranty. The Limited Lifetime
warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:
http://www.smc.com/index.cfm?action=customer_service_warranty.
All products that are replaced become the property of SMC. Replacement products may be
either new or reconditioned. Any replaced or repaired product carries either a 30-day limited
warranty or the remainder of the initial warranty, whichever is longer. SMC is not responsible
for any custom software or firmware, configuration information, or memory data of
Customer contained in, stored on, or integrated with any products returned to SMC pursuant
to any warranty. Products returned to SMC should have any customer-installed accessory or
add-on components, such as expansion modules, removed prior to returning the product for
replacement. SMC is not responsible for these items if they are returned with the product.
Customers must contact SMC for a Return Material Authorization number prior to returning
any product to SMC. Proof of purchase may be required. Any product returned to SMC
without a valid Return Material Authorization (RMA) number clearly marked on the outside
of the package will be returned to customer at customer’s expense. For warranty claims within
North America, please call our toll-free customer support number at (800) 762-4968.
Customers are responsible for all shipping charges from their facility to SMC. SMC is
responsible for return shipping charges from SMC to customer.

Introduction

Description of Software Features
The switch provides a wide range of advanced performance enhancing features.
Flow control eliminates the loss of packets due to bottlenecks caused by port
saturation. Broadcast storm suppression prevents broadcast traffic storms from
engulfing the network. Port-based and protocol-based VLANs, plus support for
automatic GVRP VLAN registration provide traffic security and efficient use of
network bandwidth. CoS priority queueing ensures the minimum delay for moving
real-time multimedia data across the network. While multicast filtering provides
support for real-time network applications. Some of the management features are
briefly described below.
Configuration Backup and Restore – You can save the current configuration
settings to a file on a TFTP server, and later download this file to restore the switch
configuration settings.
Authentication – This switch authenticates management access via the console
port, Telnet or web browser. User names and passwords can be configured locally or
can be verified via a remote authentication server (i.e., RADIUS or TACACS+).
Port-based authentication is also supported via the IEEE 802.1x protocol. This
protocol uses the Extensible Authentication Protocol over LANs (EAPOL) to request
user credentials from the 802.1x client, and then verifies the client’s right to access
the network via an authentication server.
Other authentication options include HTTPS for secure management access via the
web, SSH for secure management access over a Telnet-equivalent connection, IP
address filtering for SNMP/web/Telnet management access, and MAC address
filtering for port access.
Access Control Lists – ACLs provide packet filtering for IP frames (based on
address, protocol, TCP/UDP port number or TCP control code) or any frames
(based on MAC address or Ethernet type). ACLs can be used to improve
performance by blocking unnecessary network traffic or to implement security
controls by restricting access to specific network resources or protocols.
Port Configuration – You can manually configure the speed, duplex mode, and
flow control used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-duplex mode on ports whenever
possible to double the throughput of switch connections. Flow control should also be
enabled to control network traffic during periods of congestion and prevent the loss
of packets when port buffer thresholds are exceeded. The switch supports flow
control based on the IEEE 802.3x standard.
Rate Limiting – This feature controls the maximum rate for traffic transmitted or
received on an interface. Rate limiting is configured on interfaces at the edge of a
network to limit traffic into or out of the network. Traffic that falls within the rate limit is
transmitted, while packets that exceed the acceptable amount of traffic are dropped.
1-2
Description of Software Features
Port Mirroring – The switch can unobtrusively mirror traffic from any port to a
monitor port. You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.
Port Trunking – Ports can be combined into an aggregate connection. Trunks can
be manually set up or dynamically configured using IEEE 802.3ad Link Aggregation
Control Protocol (LACP). The additional ports dramatically increase the throughput
across any connection, and provide redundancy by taking over the load if a port in
the trunk should fail. The switch supports up to four trunks.
Broadcast Storm Control – Broadcast suppression prevents broadcast traffic from
overwhelming the network. When enabled on a port, the level of broadcast traffic
passing through the port is restricted. If broadcast traffic rises above a pre-defined
threshold, it will be throttled until the level falls back beneath the threshold.
Static Addresses – A static address can be assigned to a specific interface on this
switch. Static addresses are bound to the assigned interface and will not be moved.
When a static address is seen on another interface, the address will be ignored and
will not be written to the address table. Static addresses can be used to provide
network security by restricting access for a known host to a specific port.
IEEE 802.1D Bridge – The switch supports IEEE 802.1D transparent bridging. The
address table facilitates data switching by learning addresses, and then filtering or
forwarding traffic based on this information. The address table supports up to 8K
addresses.
Store-and-Forward Switching – The switch copies each frame into its memory
before forwarding them to another port. This ensures that all frames are a standard
Ethernet size and have been verified for accuracy with the cyclic redundancy check
(CRC). This prevents bad frames from entering the network and wasting bandwidth.
To avoid dropping frames on congested ports, the switch provides 500 KB for frame
buffering. This buffer can queue packets awaiting transmission on congested
networks.
Spanning Tree Protocol – The switch supports these spanning tree protocols:
Spanning Tree Protocol (STP, IEEE 802.1D) – 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.
Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol reduces the
convergence time for network topology changes to about 10% of that required by the
older IEEE 802.1D STP standard. It is intended as a complete replacement for STP,
but can still interoperate with switches running the older standard by automatically
reconfiguring ports to STP-compliant mode if they detect STP protocol messages
from attached devices.

Introduction

Virtual LANs – The switch 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. The switch supports tagged VLANs
based on the IEEE 802.1Q standard. Members of VLAN groups can be dynamically
learned via GVRP, or ports can be manually assigned to a specific set of VLANs.
This allows the switch to restrict traffic to the VLAN groups to which a user has been
assigned. 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 network
connection.
• Provide data security by restricting all traffic to the originating VLAN.
• Use private VLANs to restrict traffic to pass only between data ports and the uplink
ports, thereby isolating adjacent ports within the same VLAN, and allowing you to
limit the total number of VLANs that need to be configured.
Traffic Prioritization – This switch prioritizes each packet based on the required
level of service, using four priority queues with strict or Weighted Round Robin
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
independent priorities for delay-sensitive data and best-effort data.
This switch also supports several common methods of prioritizing layer 3/4 traffic to
meet application requirements. Traffic can be prioritized based on the priority bits in
the IP frame’s Type of Service (ToS) octet or the number of the TCP/UDP port.
When these services are enabled, the priorities are mapped to a Class of Service
value by the switch, and the traffic then sent to the corresponding output queue.
Multicast Filtering – 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 Query to manage multicast group registration.

Chapter 2: Initial Configuration
Connecting to the Switch
Configuration Options
The switch includes a built-in network management agent. The agent offers a variety
of management options, including SNMP, RMON and a Web-based interface. A PC
may also be connected directly to the switch for configuration and monitoring via a
command line interface (CLI).
Note: The IP address for this switch is obtained via DHCP by default. To change this
address, see “Setting an IP Address” on page 2-4.
The switch’s HTTP Web agent allows you to configure switch parameters, monitor
port connections, and display statistics using a standard Web browser such as
Netscape Navigator version 6.2 and higher or Microsoft IE version 5.0 and higher.
The switch’s Web management interface can be accessed from any computer
attached to the network.
The CLI program can be accessed by a direct connection to the RS-232 serial
console port on the switch, or remotely by a Telnet connection over the network.
The switch’s management agent also supports SNMP (Simple Network
Management Protocol). This SNMP agent permits the switch to be managed from
any system in the network using network management software such as
HP OpenView.
The switch’s Web interface, CLI configuration program, and SNMP agent allow you
to perform the following management functions:
• Set user names and passwords for up to 16 users

Required Connections
The switch provides an RS-232 serial port that enables a connection to a PC or
terminal for monitoring and configuring the switch. A null-modem console cable is
provided with the switch.
Attach a VT100-compatible terminal, or a PC running a terminal emulation program
to the switch. You can use the console cable provided with this package, or use a
null-modem cable that complies with the wiring assignments shown in the
Installation Guide.
To connect a terminal to the console port, complete the following steps:
1. Connect the console cable to the serial port on a terminal, or a PC running
terminal emulation software, and tighten the captive retaining screws on the
DB-9 connector.
2. Connect the other end of the cable to the RS-232 serial port on the switch.
3. Make sure the terminal emulation software is set as follows:
• Select the appropriate serial port (COM port 1 or COM port 2).
• Set the baud rate to 9600 bps.
• Set the data format to 8 data bits, 1 stop bit, and no parity.
• Set flow control to none.
• Set the emulation mode to VT100.
