Cooling Fans

Variable-speed cooling fans in the BayStack 350 switch provide cooling for the
internal components. When you install the switch, be sure to allow enough space
on both sides of the switch for adequate airflow.

Features

BayStack 350 switches provide wire-speed, Fast Ethernet switching that allows
high-performance, low-cost connections to full-duplex and half-duplex 10
megabits per second (Mb/s) and 100 Mb/s Ethernet local area networks (LANs).

Based on advanced application-specific integrated circuit (ASIC) technology,
BayStack 350 switches can be cost effectively deployed in 10 Mb/s networks. As
performance requirements increase and 100 Mb/s LANs are deployed, each port
uses autosensing* to support any combination of 10 Mb/s and 100 Mb/s Ethernet
LANs.

One of the many benefits provided by the BayStack 350 switch is that network
users now have the flexibility to grow from 10 Mb/s switching to 100 Mb/s
switching using a single product.

The BayStack 350 switch offers the following features:

• High-speed forwarding rate: 1.6 million packets per second (peak)

• Learning rate: 1.6 million addresses per second (peak)

• Spanning Tree Protocol: IEEE 802.1D standards compliant

• Store-and-forward switch: Full-performance forwarding at full line speed

• Rate limiting: Adjustable broadcast and multicast packet-rate limits for
control of broadcast and multicast storms

*. The BayStack 350 switch adjusts (autonegotiates) its port speed and duplex mode to match the best service

provided by the connected station, up to 100 Mb/s in full-duplex mode.

1-4 893-00992-B

Getting Started

• SNMP agent support for the following Management Information Bases
(MIBs):

— Bridge MIB (RFC 1493)
— Ethernet MIB (RFC 1643)
— Proprietary MIBs
— RMON MIB (RFC 1757)
— MIB-II (RFC 1213)

• Service port for console connection: Allows users to configure and manage
the switch locally or remotely

• TELNET:
— Support for up to four simultaneous TELNET sessions

— Optional password protection
— Login timeout
— Failed-login guard
— Inactivity timeout
— Allowed source addresses
— Event logging

• IEEE 802.3u-compliant autonegotiation ports, with four modes:
— 10BASE-T half-duplex

— 10BASE-T full-duplex
— 100BASE-TX half-duplex
— 100BASE-TX full-duplex

• Remote monitoring (RMON), with four groups integrated:
— Statistics

— History
— Alarms
— Events

• Port-based virtual LANs (VLANs)

893-00992-B 1-5

Using the BayStack 350 10/100 Autosense Switch

• Front-panel light emitting diodes (LEDs) to monitor the following:
— Power status

— System status
— Per-port status for the following:

• 100 Mb/s link

• 10 Mb/s link

• Half- and full-duplex transmission

• TX/RX activity

• Management enable/disable

• Upgradeable device firmware in nonvolatile flash memory using the Trivial
File Transfer Protocol (TFTP)

Flash Memory Storage

The BayStack 350 switch uses flash memory to store the switch software image.
Flash memory allows you to update the software image with a newer version
without changing the switch hardware. An in-band connection between the switch
and the TFTP load host is required to download the software image (refer to
“Software Download” on page 3-48). For information about connecting a console
terminal for this procedure, refer to “Service Port Cabling” on page 3-2.

If a BootP server is set up properly on the network and the BayStack 350 switch
detects a corrupted software image during the self-test, the switch automatically
uses TFTP to download a new software image.

BootP Automatic IP Configuration

The BayStack 350 switch has a unique 48-bit hardware address, or media access
control (MAC) address, that is printed on a label on the back panel. You use this
MAC address when you configure the network BootP server to recognize the
BayStack 350 switch BootP requests. A properly configured BootP serv er enables
the switch to automatically learn its assigned IP address, subnet mask, IP address
of the default router (default gateway), and software image file name. Refer to
Appendix D, “Sample BootP Configuration File,” for an example of a BootP
configuration file.

1-6 893-00992-B

SNMP MIB Support

The BayStack 350 switch supports an SNMP agent with private MIB extensions,
which ensures compatibility with existing network management tools. The
BayStack 350 switch supports MIB-II (RFC 1213) and the RMON MIB (RFC

1757), which provide access to detailed management statistics. With SNMP

management, you can configure SNMP traps (on individual ports) to be generated
automatically for conditions such as an unauthorized access attempt or changes in
a port’s operating status.

Configuration and Switch Management

The BayStack 350 switch is shipped directly from the factory ready to operate in
any 10BASE-T or 100BASE-TX standard network. You can manage the switch

®

using the Bay Networks Optivity
SNMP-based network management software; however, you must assign an IP
address to the switch. You can set the switch’s IP address by using the service port
or BootP, which resides on the switch. For more information about using the
service port to configure the switch manually, see Chapter 3, “Using the Console
Interface.”

Getting Started

Network Configuration

You can connect the BayStack 350 switch to workstations and personal computers
(PCs) either directly, using a hub, or by creating a VLAN. This section provides
three network examples using the BayStack 350 switch in the following
configurations:

• Desktop connections for power workgroups

• Desktop connections for power workgroups and shared media hub

• VLAN workgroups

Note: The BayStack 350T and 350F switches can be used interchangeably in

the following network examples.

Figure 1-4 shows power workgroups connected to servers through BayStack 350
switches in a small network. Network managers who do not want to provide each
end station with the full 100 Mb/s bandwidth can designate a certain number of
users that share the full bandwidth provided by one of the switch ports. For
example, one workgroup is connected to a 10BASE-T hub and shares 10 Mb/s
bandwidth provided by one of the BayStack 350 switch ports.

Creating VLAN W orkgroups

You can create and configure VLANs by segmenting networks into logical
workgroups that are independent of physical connections and locations. You can
define the workgroups according to project or department. As shown in
Figure 1-5, workgroup members on VLANs share computer resources but cannot
communicate with other workgroups. Access to specific servers is restricted to all
but the assigned workgroup. Broadcast packets are confined to a specific VLAN,
which relieves traffic congestion.

Refer to “VLAN Configuration” in Chapter 3 to learn how the BayStack 350
switches in Figure 1-5 are configured for this example.

After verifying proper operation of the BayStack 350 switch, refer to Chapter 3,
“Using the Console Interface,” to configure and manage the switch.

893-00992-B 2-15

Overview

Chapter 3

Using the Console Interface

This chapter describes how to configure and manage the BayStack 350 10/100
Autosense Switch using the menu-driven console interface (CI). You can access
the CI menus and screens through the service port located on the switch back
panel. You can also manage the BayStack 350 switch using Bay Networks
Optivity network management software or a generic SNMP-based management
application; however, you must first assign an IP address to the switch, as
described in this chapter. If you have a properly configured BootP server in your
network, the IP address of the BayStack 350 switch will be detected
automatically, so you will not have to configure the IP address.

Note: Refer to your network management documentation for information

about SNMP network management.

Console Interface

The CI consists of menus and screens that enable you to manage the BayStack
350 switch and monitor its performance. You can manage the switch by using
configuration menus to change its operational parameters. You can monitor the
performance of the switch by using the statistics screen, which displays the
counters of the switch ports.

You can access the CI menus and screens in the following ways:

• Locally, through a console terminal (must be a VT100-compatible terminal or
a PC running VT100 terminal-emulation software)

• Remotely, through a dial-up modem connection

• Through an in-band TELNET session

893-00992-B 3-1

Using the BayStack 350 10/100 Autosense Switch

Service Port Cabling

You can connect a console terminal directly to the BayStack 350 switch service
port, or you can connect a modem to the switch service port for remote access to
the CI menus and screens.

Note: To ensure correct connections between the service port and the console

terminal or modem port, refer to the service-port pin assignments in
Appendix B, “Connectors and Pin Assignments.”

Console T erminal Requirements

To connect a console terminal to the BayStack 350 switch service port, you need
the following equipment:

• An ASCII character terminal that has an RS-232 serial port, or a computer
that has an RS-232 serial port and terminal emulation (typically a PC running
common communications software)

• A standard RS-232 serial communications cable with a DB-9 connector at one
end for connection to the service port, and an appropriate connector (typically
a DB-9 or DB-25 connector) at the other end for connection to the serial port
on the console terminal

Modem Requirements

To connect a modem to the BayStack 350 switch service port, you need the
following equipment:

• A 9600 baud (or higher speed) modem is recommended. The service port
speed is set to 9600 baud (the default factory setting), but supports 2400 to
38400 baud, as long as the speed at both ends of the communications link are
identical.

• A standard RS-232 serial communications null-modem cable with a DB-9
connector at one end for connection to the service port, and an appropriate
connector (typically a DB-9 or DB-25 connector) at the other end for
connection to the modem’s serial port.

Set the modem’s serial port speed to match the speed of the BayStack 350 switch
service port (9600 baud is the default). See “Service Port Configuration” on

3-37 to modify the switch service port.

Connecting to the BayStack 350 Switch Service Port

To connect a console terminal or modem to the BayStack 350 switch service port,
follow these steps:

1. Plug the RS-232 cable DB-9 receptacle into the service port plug. Secure

the connection by tightening the two screws on the DB-9 receptacle.

2. Plug the other end of the RS-232 cable (DB-9 or DB-25, as appropriate)

into the RS-232 serial port on the console terminal or modem.

Accessing the CI Menus and Screens

You can access the CI menus and screens locally through a console terminal,
remotely through a dial-up modem connection, or through a TELNET session.

T o access the CI menus and screens through a TELNET session, your w orkstation
must be configured with an IP address, and you must know the IP address of the
switch in order to establish a link. You can configure an IP address for the
BayStack 350 switch by using a console terminal (as described in this section). If
you have a properly configured BootP server in your network, the IP address of
the BayStack 350 switch will be detected automatically, so you will not have to
configure the IP address. Refer to your TELNET documentation for information
about establishing TELNET connections.

To access the CI menus and screens, follow these steps:

1. Power up the console terminal, or make sure that your PC is running in

terminal-emulation mode.

2. Set the console terminal configuration parameters as follows:

Choosing a BootP Request Mode

The BootP Request Mode field in the IP Configuration screen allows you to
choose which method the switch uses to broadcast BootP requests:

• BootP When Needed

• BootP Always

• BootP Disabled

• BootP or Last Address
The following sections describe the BootP request modes.

BootP When Needed

This mode allows the switch to request an IP address if one has not already been
set from the console terminal.

When selected, this mode operates as follows:

• When the IP data is entered from the console terminal, the data becomes the
in-band address of the switch and BootP requests are not broadcast. The
switch can be managed using this in-band IP address.

Using the Console Interface

• When the in-band IP address is not set from the console terminal, the switch
broadcasts BootP requests until it receives a BootP reply containing an IP
address. If the switch does not receive a BootP reply that contains an IP
address, the switch cannot be managed in-band.

If an IP address is not currently in use, these actions take effect immediately.
If an IP address is currently in use, these actions take effect only after the switch is

reset or power cycled.

893-00992-B 3-11

Using the BayStack 350 10/100 Autosense Switch

BootP Always

This mode allows the switch to be managed only when configured with the IP
address obtained from the BootP server.

When selected, this mode operates as follows:

• The switch continues to broadcast BootP requests, regardless of whether an
in-band IP address is set from the console terminal.

• If the switch receives a BootP reply that contains an in-band IP address, the
switch uses this new in-band IP address.

• If the switch does not receive a BootP reply, the switch cannot be managed

If an IP address is not currently in use, these actions take effect immediately.
If an IP address is currently in use, these actions take effect only after the switch is

reset or power cycled.

BootP Disabled

This mode allows the switch to be managed only by using the IP address set from
the console terminal.

When selected, this mode operates as follows:

• The switch does not broadcast BootP requests, regardless of whether an IP
address is set from the console terminal.

• The switch can be managed only by using the in-band IP address set from the
console terminal.

These actions take effect after the switch is reset or power cycled, even if an IP
address is not currently in use.

3-12 893-00992-B

Using the Console Interface

BootP or Last Address

This mode allows the switch to be managed even if a BootP server is not be
reachable.

When selected, this mode operates as follows:

• When the IP data is entered from the console terminal, the data becomes the
in-band address of the switch and BootP requests are not broadcast. The
switch can be managed using this in-band IP address.

• When the in-band IP address is not set from the console terminal, the switch
broadcasts BootP requests until it receives a BootP reply containing an
in-band IP address. If the switch does not receive a BootP reply that contains
an in-band IP address within 10 minutes, the switch uses the last in-band IP
address that it received from a BootP server. This IP information is displayed
in the Last BootP column.

If an IP address is not currently in use, these actions take effect immediately.
If an IP address is currently in use, these actions take effect only after the switch is

reset or power cycled.

VLAN names. To enable a port to be shared by users on different VLANs, select
that port under each VLAN you want users to share.

3-22 893-00992-B

Using the Console Interface

You can create VLANs for one BayStack 350 switch, or you can create VLANs
that span multiple switches. However, each switch that participates in the VLAN
configuration must be configured separately.

You can also assign multiple VLANs to a port connected to a server, which allo ws
the server to be shared by multiple logical workgroups.

Note: To assign multiple VLANs to two switches, one connection per VLAN

is required between the switches. Do not assign multiple VLANs to
switch-to-switch connections.
