Chapter 1

About the Model 2216T Ethernet Switch

The Model 2216T switch is implemented as a 16-port, IEEE 802.1d-compliant 10BASE-TX Ethernet switch. This switch provides store-and-forward bridging between all 10 megabit per second (Mb/s) 10BASE-T ports. An additional seventeenth port on the switch allo ws a high-speed 100BASE-TX connection to a server. Each port on the switch operates at full Ethernet wire speed with full address and frame ﬁltering. The switch automatically learns addresses and maintains them in a dynamic address table for making forwarding decisions.

For network management, the Model 2216T switch includes a standardscompliant SNMP agent. This agent allows network management station applications to collect and present status and performance information about a switch and to perform conﬁguration and control functions on the device.

In addition, you can manage the switch in band using the popular TCP/IP application Telnet. A serial console port allows out-of-band management using a standard VT100 or similar terminal.

This chapter provides the following information:

• Summary of operational features (see page 1-2)

• Physical description of the switch (see page 1-5)

893-00980-A 1-1

Using the Model 2216T Ethernet Switch

Features

The Model 2216T switch has the following operational features:

• Seventeen switched ports: — Sixteen switched, half-duplex 10BASE-T ports — One switched, half/full-duplex 100BASE-TX port

• Transparent bridging with support for 1024 MAC addresses

• Store-and-forward switching

• IEEE 802.1d Spanning Tree Protocol support

• Static MAC or destination address ﬁltering

• Port mirroring that allows you to monitor network trafﬁc through a station port

• In-band and out-of-band interface options for conﬁguration and management

• Industry-standard Trivial File Transfer Protocol (TFTP) for downloading ne w switching software

• Nonvolatile storage of operating parameters

• SNMP support

• Optivity support

• LEDs to indicate switch operating conditions

Transparent Bridging

The Model 2216T switch is fully compliant with IEEE 802.1d transparent bridging speciﬁcations. The switch automatically “learns” addresses and maintains an aggregate address table containing 1024 entries for learning, ﬁltering, and forwarding. You can also provide static address entries and apply various frame forwarding options based on destination MAC addresses in the table. The address table and ﬁltering options are accessed out of band through a connection to the console port or in band using Telnet.

1-2 893-00980-A

Store-and-Forward Switching

The Model 2216T switch is a store-and-forward device. Each frame is copied into switch memory before being forwarded to another port. This method ensures that all forwarded frames conform to the standard Ethernet frame size and have a correct cyclic redundancy check (CRC) for data integrity. This switching method prevents bad frames from traversing the network and using up valuable network bandwidth.

To minimize the possibility of dropping frames on congested ports, the Model 2216T switch provides 2 megabytes (MB) of buffering, dynamically allocatable among all ports. This buffer space is used to queue packets for transmission on congested networks and represents an advantage over “cut-through” switching technology, which drops packets immediately when experiencing collisions.

Spanning T ree Protocol

The Model 2216T switch supports the IEEE 802.1d Spanning Tree Protocol, which allows redundant connections to be created between LAN segments for fault tolerance. You can create two or more physical paths through the switch between different segments, with the Spanning Tree Protocol choosing a single path at any given time and disabling all others. If the chosen path fails for any reason, a disabled alternative is activated, thereby maintaining the connection. This mechanism prevents network trafﬁc from circulating in an endless loop formed by multiple connections to the same LAN segment.

About the Model 2216T Ethernet Switch

The switch is shipped from the factory with spanning tree operation disabled. You can modify spanning tree operation through the out-of-band console interface or in band using SNMP or Telnet.

893-00980-A 1-3

Using the Model 2216T Ethernet Switch

Port Mirroring

A port mirroring feature in the switch allows the trafﬁc transmitted and received on a speciﬁc 10BASE-T port to be copied to a mirror port (port 1), to which you can attach a LAN analyzer or RMON probe. You can leave the analyzer or probe permanently connected to the mirror port and steer it to monitor any of the remaining 15 10BASE-T ports or segments. Port mirroring for the 100BASE-T port is not supported.

You enable the port mirroring feature through the console port. When this feature is enabled, the port 1 LED blinks a number of times to indicate the number of the port that it is currently mirroring.

Software Download

The Model 2216T switch supports the industry-standard Trivial File Transfer Protocol (TFTP) for downloading switch software to the unit. All switch software is stored in a 512 kilobyte (KB) sectored ﬂash ROM. This feature allows you to easily install upgrades and make changes to the unit.

The downloader software is invoked in one of the following ways:

• Out of band, using the switch serial console interface (See Chapter

“Downloading Software.”)

• In band, using Telnet (See “Using the page 4-18.)

Telnet Interface for Management” on

Nonvolatile Parameter Storage

Important operating parameters, such as IP addresses, spanning tree conﬁguration, and management security parameters, are stored in nonvolatile ﬂash memory and retain their values when the switch unit experiences power interruptions or is powered down for normal maintenance.

1-4 893-00980-A

Conﬁguration and Management Interfaces

The switch provides the following three interface types for management and conﬁguration:

• Serial console port, out of band An RS-232 connection using a DB-9 connector allows you to connect a

100BASE-TX Port

A single RJ-45 connector, labeled 100BASE-TX, provides connection to an optional 100BASE-TX Fast Ethernet network segment or end station. This UTP port is wired as an MDI-X connection. By default, this port operates in half-duplex mode. You can set the port for full-duplex operation to connect it to full-duplex-capable devices.

Workstations or servers with MDI connections can be connected directly to this port using an EIA/TIA-standard Category 5 straight-through cable. To connect a hub or other device with an MDI-X port to this port, you must use a Category 5 crossover cable. For connector pin assignments and cable speciﬁcations, see

Connecting to Ethernet Hubs and Network Devices

When you connect the Model 2216T switch to another Ethernet switch or an Ethernet hub, remember that all the UTP ports are conﬁgured as MDI-X connections. Follow these guidelines for connecting the ports:

• Personal computers (PCs) and servers typically have network interface controllers (NICs) that are conﬁgured as MDI connections. To connect these devices, use a straight-through cable.

• Hubs and other switches typically have connectors that are conﬁgured as MDI-X. To connect these devices, use a crossover cable, unless they have MDI ports.

For more information about MDI-X ports, see Appendix

Speciﬁcations.”

Network Conﬁguration Examples

The Model 2216T switch is well suited for two types of switching application:

• Desktop switching for up to 260 users in a network using 100 Mb/s switches

• Backbone connections to a 100 Mb/s switch

Client/Server Network

To improve workstation performance in a client/server environment, the Model 2216T Ethernet Switch can be conﬁgured to provide full 10 Mb/s Ethernet connections to individual workstations by connecting each to a dedicated switch port (see Figure 100 Mb/s port to eliminate bottlenecks to that device.

Installing the Switch

This chapter describes the physical installation of the Model 2216T switch. After a switch is installed, you can connect it to your network immediately and use the default operating parameters. The switch automatically learns network addresses and immediately begins switching network trafﬁc.

You can also modify the switch conﬁguration to meet your particular network requirements. Common items you may wish to conﬁgure include 100BASE-T half- or full-duplex operation, an IP address for Telnet and SNMP management, network management security features, and spanning tree parameters. If you decide to change the switch from its default settings, continue on to Chapter

“Conﬁguring and Operating the Switch,” after you complete the installation

procedures described in this chapter.

This chapter includes information on the following topics:

• Preparing the installation site for the switch (see “Site Requirements” on page 3-2)

• Package contents (see “Unpacking the Switch

• Installing the switch on a table or in a rack (starting on page 3-3)

• Connecting power and verifying switch operation (starting on page 3-4)

• Connecting network cables (starting on page 3-8)

The Uplink LED on the front of the switch lights green with trafﬁc on the port.

The Model 2216T switch is now switching trafﬁc between all actively connected ports, acting as a 16-port transparent bridge. It automatically learns the addresses of all end stations communicating through each port and appropriately directs trafﬁc between the ports. The switch can function with no changes to the factory default settings. (For a list of factory default settings, see Chapter

4, “Conﬁguring

and Operating the Switch.”)

If you need to modify the switch operation (for example, to set an IP address for network management or to conﬁgure spanning tree features), you must connect the console port. For instructions on how to connect this port, see “Connecting a

Terminal to the Console Port” on page 4-2.

Caution: The factory default settings of the switch do not include password

protection. The default access rights are set to READ/WRITE. To prevent unauthorized changes to the conﬁguration, set a password as described in

“Setting P

assword Protection” on page 4-6.

Chapter 4

Conﬁguring and Operating the Switch

When the physical installation of the Model 2216T switch is completed, it begins operating with its factory default conﬁguration. However, the switch provides a series of console port menus that allow you to customize switch operating parameters for your particular network and to monitor switch operation. You can set security features, establish address handling conditions, and enable or disable ports through the console interface. In addition, to manage the switch or access the switch through Telnet, you must use the console menus to set certain parameters, such as the IP address for the switch.

This chapter provides information about the following topics:

• Using factory default settings (see this page)

• Connecting to the console port (see page 4-2)

• Setting up and monitoring the switch (see page 4-5)

• Using the Telnet interface for management (see page 4-18)

Using Factory Default Settings

Connecting a Terminal to the Console Port

The serial console interface is an RS-232 port that enables a connection to a PC or VT100 terminal for monitoring and conﬁguring the switch. You can also connect this port to an external modem to enable remote dial-in management of the switch. The port is implemented as a data communication equipment (DCE) connection, using a male DB-9 connector.

To use the console port, you need the following equipment:

• A VT100 terminal or TTY-compatible terminal, or a portable computer with a serial port and the ability to emulate a VT100 terminal

The terminal should have the following settings: — 9600 baud — No parity — 8 bits — 1 stop bit

Using the Model 2216T Ethernet Switch

Using the Telnet Interface for Management

Telnet is a common terminal emulation application used in TCP/IP networks for remote terminal access to computer devices. You can use Telnet over an Ethernet network to remotely conﬁgure and monitor the Model 2216T switch. Up to two Telnet sessions can run concurrently.

Before you can access the switch over Telnet, you must assign an IP address to the switch as described on page 4-7. Then you can establish a T elnet connection to the switch. All the console menus are available through this connection, and you use the menus exactly as they are described in this chapter and in Appendix

“Menus and Commands.”

Note: If the Telnet connection is idle for 15 minutes, the connection is closed.

4-18 893-00980-A

You can upgrade switching software in the Model 2216T switch without physically opening the unit. The storage sector for switching software in the ﬂash memory of the switch is reprogrammable, allowing you to easily download software feature enhancements and problem ﬁxes to the switch.

Downloading Software

You can download software to the switch in the following two ways:

Chapter 5

Downloading Software

• A direct serial download is an out-of-band operation that copies the software through the console port to the switch. This operation takes approximately 10 minutes but requires the least conﬁguration.

• A TFTP download provides in-band remote download from a TFTP server over the network. A TFTP download is much faster than a serial download, requiring only a few seconds, and can be used to upgrade a switch that is not physically close. The disadvantage is that this method requires a TFTP server and more setup.

Direct Serial Download

A serial download is the easiest method to upgrade the switch software. This method is also the only kind of download you can perform if the ﬂash memory is corrupted in the switch.

893-00980-A 5-1

Using the Model 2216T Ethernet Switch

To perform a direct serial download, you need the following equipment:

• A personal computer (PC) with a 1.4 MB ﬂoppy drive The PC should be running a terminal-emulation program with xmodem

capability, such as Procomm Plus, Windows Terminal Emulation, or Windows 95. For information about the conﬁguration settings for these programs, see Appendix C, “Sample Terminal Conﬁgurations.”

• A cable to connect the PC to the console port on the switch

• A diskette containing the upgrade software (available from your reseller or Bay Networks Customer Support)

To prepare for the serial download, follow these steps:

1. Set the conﬁguration settings for the terminal-emulation program on

the PC.

2. Connect the PC to the console port on the switch, as described in

“Connecting a

3. Press [Esc] to display the Main Menu.

downloader.

If you press [Esc] again, the switch goes through a reset. If you press any other key, the switch reenters the downloader.

After you access the downloader , the ne xt step is to copy the ﬁle to the serial port. The following example copies the software upgrade to the switch using Procomm Plus as a terminal emulator.

To copy the software upgrade to the switch, follow these steps:

1. While the “attempting download” message is displayed on the screen,

insert the upgrade disk into a drive (for example, drive A).

2. Press PgUp to access the Send File utility.

3. Press X for an XMODEM transfer.

4. At the Enter Filename prompt, enter a ﬁle name, as in the following

example:

A:\xxxxx.img

When the transfer begins, the Test LED stops ﬂashing and remains lit. The following message is displayed:

Download method established to be via: the serial port.

Download in Progress....

Downloading software through the serial port takes 5 to 10 minutes. When the download is complete, the switch automatically resets itself and comes up running the new software.

Note: When the switch resets, it loses any Telnet connections.

The ﬁnal stage in downloading software is to verify that the new software was downloaded successfully. See “V

Port Number to Be Mirrored

This command disables the extensive power-up diagnostics in the switch. The default value for this command is YES. For problem troubleshooting, set this command to NO to enable the extensive diagnostics.

Use this command to enable the port mirroring capabilities of the switch. Using port mirroring, trafﬁc transmitted and received on any 10BASE-T port is mirrored to port 1. When port mirroring is enabled, port 1 ceases to be a switch port and instead mirrors the trafﬁc on the port speciﬁed by the Port Number to Be Mirrored parameter. The port 1 LED blinks a certain number of times corresponding to the number of the port currently mirrored.

Use this parameter to specify the number of the port with trafﬁc currently mirroring to port 1. This value is meaningful only if the Port Mirroring Enabled value is YES. Enter a port number from 2 to 16. Port mirroring is not supported for the 100BASE-TX port.
