FORMULA 8200 User’s Guide

Note

Do not enter the brackets when you enter the command.

The LOOKUP

Command Command

Formats

Entering LOOKUP is a way to get a list of commands, their corresponding aliases, and descriptions.

The software allows you to enter commands in three ways:

❑ By entering the complete command ❑ By using a shortcut ❑ By using an alias

Separating Command Words

When you enter any command, you may separate the command words with a slash (/). For example:

/FDDI/SHOW/SMT

You may also use a space to separate the command words.

Shortcuts

Use a shortcut by typing the ﬁrst few characters needed to distinguish the command from others that start with the same letters, such as:

/FD/SH/SMT

This works unless your shortened version is ambiguous, which causes an error message to appear.

Aliases

An alias is an abbreviated command that can be accessed from anywhere in the command line interface. For example, the following alias is equivalent to the

fsmt

FDDI/SHOW/SMT command:

Aliases are listed in Appendix A, and are also listed in Chapter 5 with each command description.

You may occasionally need to reset the FORMULA 8200. You can do this in one of three ways:

❑ The Reset button on the front panel permits you to perform a

“hardware reset,” and does not require you to use the command line interface.

❑ The REBOOT command permits you to reset the switch via

the command line interface, either from the local console, or from a remote location via Telnet. The current Telnet session is disconnected by this command.

❑ The On/Off switch in the rear panel recycles the power to the

switch.

Either method initializes the hardware, loads the system software from the ﬂash, restores the switch to the current (saved) conﬁguration settings, and restarts the switch. Upon restart, the POST and other diagnostic information appear on the local console, followed by the login and password prompts.

Conﬁguring the FORMULA 8200 Switch

This chapter describes:

❑ System default configurations ❑ An overview of virtual LANs (VLANs) and related parameters,

including Spanning Tree (virtual bridges) and virtual routers, and how to configure them

Default Configurations

The FORMULA 8200 is shipped from the factory with the following default conﬁgurations:

❑ Console speed is 9600 ❑ Login is admin and password is switch ❑ Autonegotiation is ON (enabled) for 10/100 Mbps TX ports ❑ Ethernet statistics are disabled ❑ All ports belong to the default VLAN 1 ❑ Spanning Tree is enabled ❑ RIP (virtual routing) is silent

These settings provide for switching a single broadcast domain. To display and conﬁgure port settings, refer to Chapter 4 beginning on page 4-5.

3-1

Optimizing Functionality for Your Application

The FORMULA 8200, unlike shared media switching hubs, allows you to divide your LAN into smaller segments. This incr eases and uses full LAN bandwidth for each segment. By providing high end devices such as workstations, servers, and routers their own dedicated connections to the switch, you can signiﬁcantly increase throughput and decrease latency.

In addition to creating one or more VLANs to reduce broadcast trafﬁc, you can also customize the conﬁguration to meet your speciﬁc needs. Use the information in the remainder of this chapter; you can also review the command set in Chapter 5 for more speciﬁc information.

Virtual LANs

A Virtual LAN (VLAN) is a logical group of LANs or individual devices, established without regard to their physical location on the network. You can group any collection of ports on one or more FORMULA 8200 switches into a VLAN.

Since you can connect either a LAN or a device to a port in the FORMULA 8200, any group of LANs or individual devices connected to the switch can be connected together in a VLAN.

The LAN segments that comprise a VLAN can be distributed among multiple switches that are interconnected by a backbone network. This grouping of LAN segments into VLANs reduces the amount of work required when moving an end station from one LAN segment to another.

VLANs also maximize the efﬁcient use of the bandwidth on any given LAN segment, since packets are forwarded only between segments as required. The separation of segments into VLANs also provides security, since data from a workgroup on one VLAN will not be seen on the VLANs for other workgroups. VLANs also create smaller broadcast domains, which reduce broadcast trafﬁc across the network.

3-2

Note

To communicate between VLANs, the FORMULA 8200 must be configured to enable RIP for IP routing. If additional protocols are required, a connection on each VLAN must go to an external router.

FORMULA 8200 User’s Guide

FORMULA 8200

Implementation

of VLANs

The FORMULA 8200 consists of up to 16 physical network interfaces. In its simplest conﬁguration, all of these network interfaces are grouped together into a single bridged virtual LAN (VLAN). Trafﬁc ﬂowing between end stations on separate LAN segments is switched by a virtual bridge.

You may conﬁgure up to 16 VLANs. Each FORMULA 8200 has a default VLAN, called VLAN 1 (Figure 3-1).

The default VLAN cannot be remo ved . It contains all virtual interfaces not assigned to other VLANs. Initially, all interfaces are members of the default VLAN.

VLAN1 (Default VLAN)

Switch 1

Switch 2

Switch 3

Figure 3-1: Default VLAN 1

You can, however, create up to 16 VLANs on each switch on a perport basis. This feature allows you to move network interfaces from the default VLAN to other VLANs (see Figure 3-2). Trafﬁc can then ﬂow between VLANs by using either an external router or by using the virtual router service provided internally by the FORMULA 8200.

FORMULA 8200 VLANs are port-based. A port cannot be part of more than one VLAN. That is, if your FORMULA 8200 is conﬁgured for 8 ports, the switch can support up to 8 VLANs; if your switch includes an 8-port expansion module, it supports up to 16 VLANs.

Use the

VLAN/SHOW/VPORT command to see the virtual port

information. Refer to Chapter 5 for details on the command. Each VLAN represents one IP subnet. Unlike a traditional router,

where each interface represents a different subnet, FORMULA 8200 VLAN switching allows multiple interfaces to share an IP subnet. If you move an end station from one LAN segment to another within the same VLAN, whether it is a local segment or a remote one, there is no need to reconﬁgure its IP address.

FORMULA 8200 User’s Guide

Virtual Bridges,

Virtual

Interfaces,

Virtual Routers

Each VLAN has a virtual bridge that maintains the locations of the end stations on each segment and controls the switching hardware. Each of the interfaces on a virtual bridge is called a

virtual interface.

Each VLAN is identiﬁed by a number. These numbers are global to all FORMULA 8200 switches that are connected by a backbone network. Trafﬁc can be exchanged over a backbone network in order to allow a VLAN to have segments that are distributed among multiple FORMULA 8200 switches. Trafﬁc can be exchanged between VLANs by either internal or external routing.

Use the

VLAN/SHOW/VLAN command to see the virtual VLAN

information. Refer to Chapter 5 for details on the command. An optional virtual router interface can be conﬁgured to forward

trafﬁc between VLANs by using the

VLAN/CONFIG command; see

Configuring a Virtual LAN (VLAN) later in this chapter. Use the

VLAN/SHOW/VROUTER command to see the virtual router

information. Refer to Chapter 5 for details on the command. To access the FORMULA 8200 management applications remotely

via TCP/IP, the IP interface must be enabled on at least one VLAN (usually VLAN 1). The management applications may then be accessed from a station that has access to one of the LAN segments comprising that VLAN. If the interface over which management functions are taking place is disabled, it is possible to lose contact with the FORMULA 8200. In this case, you must use the console port to reestablish remote TCP/IP management capabilities.

Each VLAN has an associated virtual bridge. A distributed VLAN has one virtual bridge on each FORMULA 8200 that has interfaces participating in the VLAN. The virtual bridge implements the IEEE

802.1-D Spanning Tree Algorithm and Protocol, described in the next section.

Use the information, and

Spanning Tree Spanning Tree is a conﬁguration algorithm and protocol that ensures

that no data loops exist within a single broadcast domain. For example, Figure 3-3 shows bridges 1 and 2 in a loop; in this conﬁguration without Spanning Tree, the network is unusable.

Figure 3-4: Spanning Tree Eliminating Data Looping

By blocking the port at Bridge 2, data can pass to all three segments. In this example, either Bridge 1 or Bridge 3 becomes the “root” bridge, depending on priority or MAC address, and the remaining bridge then becomes a “standb y” bridge , ready to function if a failure should occur in the Bridge 1.

FORMULA 8200 User’s Guide

In addition to preventing looping, Spanning Tree provides the following functions:

❑ Automatic reconfiguring of the topology in the event of a

failure or the addition of a bridge or a bridged port

❑ Topology stability, regardless of the size of the bridged VLAN ❑ Configuration management, by displaying statistics and user-

specified bridge and port priorities, parameters, and timers

Spanning Tree performs the above functions by exchanging BPDUs (Bridge Protocol Data Units) packets between bridges. When the topology changes, the time it takes for Spanning Tree to stabilize depends on the size of the bridged network and several userconﬁgurable parameters.

Spanning T r ee Protoc ol functions by putting its ports in the following modes or states:

Blocking State - In this state, ports do not forward packets and do not learn addresses. The ports are in standby mode until a topology change occurs.

Listening State - In this state, ports do not forward packets and do not learn addresses.

Learning State - In this state, ports do not forward packets in either direction, but they learn station addresses.

Forwarding State - In this state, ports forward and learn all packets in either direction.

The listening state and learning state are both temporary states as the port moves into forwarding state.

Use the

VBRIDGE/SHOW/BRIDGE<VLAN#> command to view the

current conﬁguration settings. To enable and conﬁgure Spanning Tree, use the

BRIDGE<VLAN#> command, or refer to Configuring a Virtual

VBRIDGE/CONFIG/

Bridge later in this chapter.

Configuring a Virtual LAN (VLAN)

Use this procedure to assign ports to create a VLAN, including a virtual router, if desired. By default, all the ports on your FORMULA 8200 are assigned to VLAN 1. If this conﬁguration suits your needs, use VLAN 1 to deﬁne port assignments. Otherwise, create more VLANs to establish user groups and manage network trafﬁc.

As you create additional VLANs, the ports you assign to them are removed from VLAN 1 (that is, a port cannot be in two VLANs at the same time).

To configure a VLAN:

The following steps are for cr eating VLAN 2 and for assigning ports 4 and 5 to VLAN 2. If you use these steps to create a VLAN, be sure to assign your own VLAN name, port numbers, IP address, and so on.

1. From the switch on which the ports reside, enter:

/VLAN/CONFIG

2. Create VLAN 2 by entering:

CREATE 2

3. Answer each prompt as it appears, and then confirm with a y at the end. Refer to the following example (bolded text represents user entries):

/VLAN/CONFIG/CREATE 2

VLAN ID : 2 VLAN Description (VLAN 2) : TEST Initial Ports : 4 5 VLAN enabled (yes) : y VLAN 2 is successfully created

In the example:

❑ The VLAN Description shown here is TEST, but you can enter

any text up to 32 characters.

❑ The Initial Ports parameter allows you to specify which ports

are included in the VLAN. This can be modified later by using one of the following commands:

Using Ethernet Port Mirroring

You need to provide a network analyzer to monitor trafﬁc on the FORMULA 8200.

Port mirroring lets you nonintrusively monitor the network trafﬁc on one port from another port. You can set up port mirroring for any pair of Ethernet ports within the same switch. When you enable port mirroring, the active or mirrored port transmits and receives normally, and the mirroring or snoop port receives a copy of the receive trafﬁc of that active port.

Before using the port mirroring feature, you must enable port statistics hardware and statistics polling by using the

CONFIG/STAT command.

Note

In Case of

Problems With

the Software

Upgrade

This section tells you what to do if the software upgrade fails due to interruptions or if you see error messages while rebooting the switch as part of the upgrade process.

Interruptions during the download process

Interrupting a software download (for example, rebooting the switch or disconnecting the power cord) creates ﬁles of 0 bytes. Attempts to download again will not succeed because the download process cannot write over these ﬁles.

If you encounter these problems:

1. Log in to the switch.

2. Manually delete the firmware file by entering:

/FILE/DELETE firmware

3. Download the firmware again.

Error message during the boot process

If you see the following error message:

error uncompressing file status=0X3D00Q can’t load boot file.

this means you can not use the CLI to download. Refer to Appendix C, Downloading Software at the [VxWorks] Prompt, for alternate procedures on how to download software to the FORMULA 8200.
