Selecting a Management Interface

This chapter describes the following:

■ Management interfaces for the SMC6624M switch

■ Advantages of using each interface

Understanding Management Interfaces

Management interfaces enable you to reconfigure the switch and to monitor switch status and performance. The SMC6624M switch offers the following interfaces:

■ Menu interface—a menu-driven interface offering a subset of switch

commands through the built-in VT-100/ANSI console—page 1-2

■ CLI—a command line interface offering the full set of switch commands

through the VT-100/ANSI console built into the switch—page 1-3

■ Web browser interface --a switch interface offering status information

and a subset of switch commands through a standard web browser (such as Netscape Navigator or Microsoft Internet Explorer)—page 1-4

Selecting a Management

Interface

This manual describes how to use the menu interface (chapter 2), the CLI (chapter 3), the web browser interface (chapter 4), and how to use these interfaces to configure and monitor the switch.

■ Easy access to the switch from anywhere on the network

■ Familiar browser interface--locations of window objects consistent

with commonly used browsers, uses mouse clicking for navigation, no terminal setup

■ Many features have all their fields in one screen so you can view all

values at once

■ More visual cues, using colors, status bars, device icons, and other

graphical objects instead of relying solely on alphanumeric values

■ Display of acceptable ranges of values available in configuration list

boxes

For specific requirements, see “Web Browser Interface Requirements” on page 4-3.

Using the Menu Interface

This chapter describes the following features:

■ Overview of the Menu Interface (page 4-1)

■ Starting and ending a Menu session (page 2-2)

■ The Main Menu (page 2-6)

■ Screen structure and navigation (page 2-8)

■ Rebooting the switch (page 2-11)

The menu interface operates through the switch console to provide you with a subset of switch commands in an easy-to-use menu format enabling you to:

■ Perform a “quick configuration” of basic parameters, such as the IP

addressing needed to provide management access through your network

■ Configure these features:

Using the Menu Interface

• Manager and Operator passwords

• System parameters

• IP addressing

•Ports

• One trunk group

■ View status, counters, and Event Log information

■ Download new software system

■ Reboot the switch

• A network monitoring port

• Stack Management

• Spanning Tree operation

• SNMP community names

•IP authorized managers

• VLANs (Virtual LANs)

For a detailed list of menu features, see the “Menu Features List” on page 2-13.

Privilege Levels and Password Security. SMC strongly recommends that you configure a Manager password to help prevent unauthorized access to your network. A Manager password grants full read-write access to the switch. An Operator password, if configured, grants access to status and counter, Event Log, and the Operator level in the CLI. After you configure passwords on the switch and log off of the interface, access to the menu interface (and the CLI and web browser interface) will require entry of either the Manager or Operator password. (If the switch has only a Manager password, then someone without a password can still gain read-only access.)

menu command.

Starting and Ending a Menu Session

You can access the menu interface using any of the following:

■ A direct serial connection to the switch’s console port, as described in the

installation guide you received with the switch

■ A Telnet connection to the switch console from a networked PC or the

switch’s web browser interface. Telnet requires that an IP address and subnet mask compatible with your network have already been configured on the switch.

Using the Menu Interface

■ The stack Commander, if the switch is a stack member

Note This section assumes that either a terminal device is already configured and

connected to the switch (see the Installation Guide shipped with your switch) or that you have already configured an IP address on the switch (required for Telnet access).

menu command.

2. Do one of the following:

• If you are using Telnet, go to step 3.

• If you are using a PC terminal emulator or a terminal, press [Enter] one or more times until a prompt appears.

3. When the switch screen appears, do one of the following:

• If a password has been configured, the password prompt appears.

Password: _

Type the Manager password and press [Enter]. Entering the Manager password gives you manager-level access to the switch. (Entering the Operator password gives you operator-level access to the switch. See “Using Password Security” on page 7-2.)

• If no password has been configured, the CLI prompt appears. Go to the next step.

4. When the CLI prompt appears, display the Menu interface by entering the

menu command. For example:

SMC TigerSwitch 10/100# menu [Enter]

results in:

How To End a Menu Session and Exit from the Console:

The method for ending a menu session and exiting from the console depends on whether, during the session, you made any changes to the switch configuration that require a switch reboot to activate. (Most changes need only a S and do not require a switch reboot.) Configuration changes needing a reboot are marked with an asterisk (*) next to the configured item in the Configuration menu and also next to the Switch Configuration item in the Main Menu.

Starting and Ending a Menu Session

Using the Menu Interface

Figure 2-2. An Asterisk Indicates a Configuration Change Requiring a Reboot

1. In the current session, if you have not made configuration changes that require a switch reboot to activate, return to the Main menu and press [0] (zero) to log out. Then just exit from the terminal program, turn off the terminal, or quit the Telnet session.

2. If you have made configuration changes that require a switch reboot— that is, if an asterisk (*) appears next to a configured item or next to Switch Configuration in the Main menu:

a. Return to the Main menu. b. Press [6] to select Reboot Switch and follow the instructions on the

reboot screen.

Rebooting the switch terminates the menu session, and, if you are using Telnet, disconnects the Telnet session.

(See “Rebooting To Activate Configuration Changes” on page 2-12.)

3. Exit from the terminal program, turn off the terminal, or close the Telnet application program.

most temporary error conditions, resets the network activity counters to zero, and resets the system up time to zero. A reboot is required to activate a change in the VLAN Support parameter. (See “Rebooting from the Menu Interface” on page C-8.)

■ Download OS: Enables you to download a new software version to the

switch. (See appendix A, “Transferring an Operating System or Configuration.”)

■ Run Setup: Displays the Switch Setup screen for quickly configuring

basic switch parameters such as IP addressing, default gateway, logon default interface, spanning tree, and others. (See the Installation Guide shipped with your switch.)

■ Stacking: Enables you to use a single IP address and standard network

cabling to manage a group of up to 16 switches in the same subnet (broadcast domain). See “Stack Management” on page 9-2.

■ Logout: Closes the Menu interface and console session, and disconnects

Telnet access to the switch. (See “How to End a Menu Session and Exit from the Console” on page 2-4.)

Reconfigure (edit) a parameter setting or a field:

Use either of the following methods:

• Use the arrow keys ( [<] ,or [>] ) to highlight the action you want to execute, then press [Enter].

• Press the key corresponding to the capital letter in the action name. For example, in a configuration menu, press [E] to select Edit and begin editing parameter values.

1. Select a configuration item, such as System Name. (See figure 4-1.)

2. Press [E] (for E

3. Use [Tab] or the arrow keys ([<], [>], [^], or [v]) to highlight the item or field.

4. Do one of the following: – If the parameter has preconfigured values, either use the

Space bar to select a new option or type the first part of your selection and the rest of the selection appears automatically. (The help line instructs you to “Select” a value.)

– If there are no preconfigured values, type in a value (the Help

line instructs you to “Enter” a value).

5. If you want to change another parameter value, return to step 3.

6. If you are finished editing parameters in the displayed screen, press [Enter] to return to the Actions line and do one of the following:

– To save and activate configura tion chan ges, press [S] (for the

Save action). This saves the changes in the startup configuration and also implements the change in the currently running configuration. (See appendix C, "Switch Memory and Configuration.)

– To exit from the screen without saving any changes that you

have made (or if you have not made changes), press [C] (for the Cancel action).

Note: In the menu interface, executing Save activates most parameter changes and saves them in the startup configuration (or flash) memory, and it is therefore not necessary to reboot the switch after making these changes. But if an asterisk appears next to any menu item you reconfigure, the switch will not activate or save the change for that item until you reboot the switch. In this case, rebooting should be done after you have made all desired changes and then returned to the Main Menu.

Using the Command Line Interface (CLI)

The CLI is a text-based command interface for configuring and monitoring the switch. The CLI gives you access to the switch’s full set of commands while providing the same password protection that is used in the web browser interface and the menu interface.

Accessing the CLI

Like the menu interface, the CLI is accessed through the switch console, and, in the switch’s factory default state, is the default interface when you start a console session. You can access the console out-of-band by directly connecting a terminal device to the switch, or in-band by using Telnet either from a terminal device or through the web browser interface.

Using the Command Line

Interface (CLI)

Also, if you are using the menu interface, you can access the CLI by selecting the Command Line (CLI) option in the Main Menu.

Using the CLI

The CLI offers these privilege levels to help protect the switch from unauthorized access:

•Operator

• Manager

• Global Configuration

• Context Configuration

Note CLI commands are not case-sensitive.

3-1

Using the Command Line Interface (CLI)

Using the CLI

When you use the CLI to make a configuration change, the switch writes the change to the Running-Config file in volatile memory. This allows you to test your configuration changes before making them permanent. to make changes permanent, you must use the write memory command to save them to the Startup Config file in non-volatile memory. If you reboot the switch without first using write memory, all changes made since the last reboot or write memory (whichever is later) will be lost. For more on switch memory and saving configuration changes, see appendix C, “Switch Memory and Configuration.”

Privilege Levels at Logon

Privilege levels control the type of access to the CLI. To implement this control, you must set at least a Manager password. Without a Manager

password configured, anyone having serial port, Telnet, or web browser access to the switch can reach all CLI levels. (For more on setting passwords,

see “Using Password Security” on page 7-2.)

When you use the CLI to log on to the switch, and passwords are set, you will be prompted to enter a password. For example:

Interface (CLI)

Using the Command Line

Password Prompt

Figure 3-1. Example of CLI Log-On Screen with Password(s) Set

In the above case, you will enter the CLI at the level corresponding to the password you provide (operator or manager).

If no passwords are set when you log onto the CLI, you will enter at the Manager level. For example:

SMC TigerSwitch 10/100# _

3-2

Using the Command Line Interface (CLI)

Using the CLI

Caution SMC strongly recommends that you configure a Manager password. If a Man-

ager password is not configured, then the Manager level is not passwordprotected, and anyone having in-band or out-of-band access to the switch may be able to reach the Manager level and compromise switch and network security. Note that configuring only an Operator password does not prevent access to the Manager level by intruders who have the Operator password.

Pressing the Clear button on the front of the switch removes password protection. For this reason, it is recommended that you protect the switch from physical access by unauthorized persons. If you are concerned about switch security and operation, you should install the switch in a secure location, such as a locked wiring closet.

Privilege Level Operation

Operator Privileges

Manager Privileges

Figure 3-2. Privilege Level Access Sequence

Operator Level

Manager Level

Global Configuration Level

Context Configuration Level

Operator Privileges

At the Operator level you can examine the current configuration and move between interfaces without being able to change the configuration. A ">" character delimits the Operator-level prompt. For example:

SMC TigerSwitch 10/100> _ (Example of the Operator prompt.)

When using enable to move to the Manager level, the switch prompts you for the Manager password if one has already been configured.

Using the Command Line

Interface (CLI)

3-3

Using the Command Line Interface (CLI)

Using the CLI

Manager Privileges

Manager privileges give you three additional levels of access: Manager, Global Configuration, and Context Configuration. (See figure .) A “#” character delimits any Manager prompt. For example:

SMC TigerSwitch 10/100#_ (Example of the Manager prompt.)

■ Manager level: Provides all Operator level privileges plus the ability to

perform system-level actions that do not require saving changes to the system configuration file. The prompt for the Manager level contains only the system name and the “#” delimiter, as shown above. To select this level, enter the enable command at the Operator level prompt and enter the Manager password, when prompted. For example:

SMC TigerSwitch 10/100> enable

(Enter enable at the Operator prompt.) SMC TigerSwitch 10/100# _ (The Manager prompt.)

■ Global Configuration level: Provides all Operator and Manager level

privileges, and enables you to make configuration changes to any of the switch’s software features. The prompt for the Global Configuration level includes the system name and “(config).” To select this level, enter the config command at the Manager prompt. For example:

SMC TigerSwitch 10/100# _

(Enter config at the Manager prompt.)

Interface (CLI)

Using the Command Line

SMC TigerSwitch 10/100(config)#_

(The Global Config prompt.)

■ Context Configuration level: Provides all Operator and Manager priv-

ileges, and enables you to make configuration changes in a specific context, such as one or more ports or a VLAN. The prompt for the Context Configuration level includes the system name and the selected context. For example:

SMC TigerSwitch 10/100(eth-1)#

SMC TigerSwitch 10/100(vlan-10)#

The Context level is useful, for example, if you want to execute several commands directed at the same port or VLAN, or if you want to shorten the command strings for a specific context area. To select this level, enter the specific context at the Global Configuration level prompt. For example, to select the context level for an existing VLAN with the VLAN ID of 10, you would enter the following command and see the indicated result:

SMC TigerSwitch 10/100(config)# vlan 10

3-4

SMC TigerSwitch 10/100(vlan-10)#

Changing Interfaces. If you change from the CLI to the menu interface, or the reverse, you will remain at the same privilege level. For example, entering the menu command from the Operator level of the CLI takes you to the Operator privilege level in the menu interface.

Moving Between the CLI and the Menu Interface. When moving between interfaces, the switch retains the current privilege level (Manager or Operator). That is, if you are at the Operator level in the menu and select the Command Line Interface (CLI) option from the Main Menu, the CLI prompt appears at the Operator level.

Changing Parameter Settings. Regardless of which interface is used (CLI, menu interface, or web browser interface), the most recently configured version of a parameter setting overrides any earlier settings for that parameter.

Using the Command Line Interface (CLI)

For example, if you use the CLI to set a Manager password, and then later use the Setup screen (in the menu interface) to set a different Manager password, then the first password will be replaced by the second one.

Using the CLI

Listing Commands and Command Options

At any privilege level you can:

■ List all of the commands available at that level

■ List the options for a specific command

Listing Commands Available at Any Privilege Level

At a given privilege level you can execute the commands that level offers, plus all of the commands available at preceding levels. Similarly, at a given privilege level, you can list all of that level’s commands plus the commands made available at preceding levels. For example, at the Operator level, you can list and execute only the Operator level commands. However, at the Manager level, you can list and execute the commands available at both the Operator and Manager levels.

Type "?" To List Available Commands. Typing the commands you can execute at the current privilege level. For example, typing

? at the Operator level produces this listing:

? symbol lists the

Using the Command Line

Typing ? at the Global Configuration level or the Context Configuration level produces similar results.

Use [Tab] To Search for or Complete a Command Word. You can use [Tab] to help you find CLI commands or to quickly complete the current word in a command. To do so, press [Tab] immediately after typing the last letter of the last keyword in the CLI (with no spaces allowed). For example, at the Global Configuration level, if you press [Tab] immediately after typing “t,” the CLI displays the available command options that begin with “t.” For example:

SMC TigerSwitch 10/100(config)# t[Tab] telnet-server time trunk telnet SMC TigerSwitch 10/100(config)# t

3-8

Using the Command Line Interface (CLI)

Using the CLI

As mentioned above, if you type part of a command word and press [Tab], the CLI completes the current word (if you have typed enough of the word for the CLI to distinguish it from other possibilities), including hyphenated extensions. For example:

SMC TigerSwitch 10/100(config)# port[Tab] SMC TigerSwitch 10/100(config)# port-security _

Pressing [Tab] after a completed command word lists the further options for that command.

SMC TigerSwitch 10/100(config)# stack[Tab] commander <commander-str> join <mac-addr> auto-join transmission-interval <integer> <cr> SMC TigerSwitch 10/100(config)# stack

Command Option Displays

Conventions for Command Option Displays. When you use the CLI to list options for a particular command, you will see one or more of the following conventions to help you interpret the command data:

■ Braces ( < > ) indicate a required choice.

■ Square brackets ([ ]) indicate optional elements.

■ Vertical bars ( | ) separate alternative, mutually exclusive options in a

command.

The braces (< >) show that the trunk command requires all three parameters.

The vertical bar ( either trunk or lacp must be included.

The square brackets ([ ]) show that ethernet is optional.

Figure 3-5.Example of Command Option Conventions

| ) shows that

Using the Command Line

Using the CLI

Thus, if you wanted to create a port trunk group using ports 5 - 8, the above conventions show that you could do so using any of the following forms of the trunk command:

SMC TigerSwitch 10/100(config)# trunk trk1 trunk 5-8 SMC TigerSwitch 10/100(config)# trunk trk1 trunk e 5-8

SMC TigerSwitch 10/100(config)# trunk trk1 lacp 5-8 SMC TigerSwitch 10/100(config)# trunk trk1 lacp e 5-8

Listing Command Options. You can use the CLI to remind you of the options available for a command by entering command keywords followed by

?. For example, suppose you wanted to see the command options for config-

uring port 5:

This example displays the command options for configuring port 5 on the switch.

Displaying CLI “Help”

CLI Help provides two types of context-sensitive information:

■ Command list with a brief summary of each command’s purpose

■ Detailed information on how to use individual commands

Displaying Command-List Help. You can display a listing of command Help summaries for all commands available at the current privilege level. That is, when you are at the Operator level, you can display the Help summaries only for Operator-Level commands. At the Manager level, you can display the Help summaries for both the Operator and Manager levels, and so on.

Syntax: help

For example, to list the Operator-Level commands with their purposes:

Using the Command Line Interface (CLI)

Using the CLI

Figure 3-9. Example of Help for a Specific Instance of a Command

Note that if you try to list the help for an individual command from a privilege level that does not include that command, the switch returns an error message. For example, trying to list the help for the interface command while at the global configuration level produces this result:

SMC TigerSwitch 10/100# interface help Invalid input: interface

Configuration Commands and the Context Configuration Modes

Interface (CLI)

Using the Command Line

You can execute any configuration command in the global configuration mode or in selected context modes. However, using a context mode enables you to execute context-specific commands faster, with shorter command strings.

The SMC6624M offers interface (port or trunk group) and VLAN context configuration modes:

Port or Trunk-Group Context . Includes port- or trunk-specific commands that apply only to the selected port(s) or trunk group, plus the global configuration, Manager, and Operator commands. The prompt for this mode includes the identity of the selected port(s):

SMC TigerSwitch 10/100(config)# interface e 5-8

SMC TigerSwitch 10/100(config)# interface e trk1

SMC TigerSwitch 10/100(eth-5-8)# SMC TigerSwitch 10/100(eth-Trk1)#

Command executed at configuration level for entering port or trk1 static trunk-group context.

Resulting prompt showing port or static trunk contexts.

the port. This indicator (a gold color on many systems) enables you to know “at-a-glance” the source of any non-unicast traffic that is causing high utilization of the switch. For example, if one port is receiving heavy broadcast or multicast traffic, all ports will become highly utilized. By color-coding the received broadcast and multicast utilization, the bar graph quickly and easily identifies the offending port. This makes it faster and easier to discover the exact source of the heavy traffic because you don’t have to examine port counter data from several ports.

■ % Error Pkts Rx: All error packets received by the port. (This indicator

is a reddish color on many systems.) Although errors received on a port are not propagated to the rest of the network, a consistently high number of errors on a specific port may indicate a problem on the device or network segment connected to the indicated port.

■ Maximum Activity Indicator: As the bars in the graph area change

height to reflect the level of network activity on the corresponding port, they leave an outline to identify the maximum activity level that has been observed on the port.

Utilization Guideline. A network utilization of 40% is considered the maximum that a typical Ethernet-type network can experience before encountering performance difficulties. If you observe utilization that is consistently higher than 40% on any port, click on the Port Counters button to get a detailed set of counters for the port.

To change the amount of bandwidth the Port Utilization bar graph shows. Click on the bandwidth display control button in the upp er left corner

of the graph. (The button shows the current scale setting, such as 40%.) In the resulting menu, select the bandwidth scale you want the graph to show (3%, 10%, 25%, 40%, 75%, or 100%), as shown in figure 3-7.

Note that when viewing activity on a gigabit port, you may want to select a lower value (such as 3% or 10%). This is because the bandwidth utilization of current network applications on gigabit links is typically minimal, and may not appear on the graph if the scale is set to show high bandwidth utilization.

Each alert has the following fields of information:

■ Status – The level of severity of the event generated. Severity levels can

be Information, Normal, Warning, and Critical. If the alert is new (has not yet been acknowledged), the New symbol is also in the Status column.

■ Alert – The specific event identification.

■ Date/Time – The date and time the event was received by the web

browser interface. This value is shown in the format: DD-MM-YY HH:MM:SS AM/PM, for example, 16-Sep-99 7:58:44 AM.

■ Description – A short narrative statement that describes the event. For

Configuring IP Addressing, Interface Access, and System Information

This chapter describes the switch configuration features available in the menu interface, CLI and web browser interface. For help on how to use these interfaces, refer to:

■ Chapter 2, “Using the Menu Interface”

■ Chapter 3, “Using the Command Line Interface (CLI)”

■ Chapter 4, Using the Web Browser Interface”

Why Configure IP Addressing? In its factory default configuration, the switch operates as a multiport learning bridge with network connectivity provided by the ports on the switch. However, to enable specific management access and control through your network, you will need IP addressing. (See table 5-1 on page 5-10.)

Configuring IP Addressing,

Interface Access, and

Why Configure Interface Access and System Information? The interface access features in the switch operate properly by default. However, you can modify or disable access features to suit your particular needs. Similarly, you can choose to leave the system information parameters at their default settings. However, using these features can help you to more easily manage a group of devices across your network.

IP Address and Subnet Mask. Configuring the switch with an IP address expands your ability to manage the switch and use its features. By default, the switch is configured to automatically receive IP addressing on the default VLAN from a DHCP/Bootp server that has been configured correctly with information to support the switch. (Refer to “DHCP/Bootp Operation” on page 5-10 for information on setting up automatic configuration from a server.) However, if you are not using a DHCP/Bootp server to configure IP addressing, use the menu interface or the CLI to manually configure the initial IP values. After you have network access to a device, you can use the web browser interface to modify the initial IP configuration if needed.

For information on how IP addressing affects switch performance, refer to “How IP Addressing Affects Switch Operation” on page 5-9.

Default Gateway Operation. The default gateway is required when a router is needed for tasks such as reaching off-subnet destinations or forwarding traffic across multiple VLANs. The gateway value is the IP address of the next-hop gateway node for the switch, which is used if the requested destination address is not on a local subnet/VLAN. If the switch does not have a manually-configured default gateway and DHCP/Bootp is configured on the primary VLAN, then the default gateway value provided by the DHCP or Bootp server will be used. If the switch has a manually configured default gateway, then the switch uses this gateway, even if a different gateway is received via DHCP or Bootp on the primary VLAN. See “Notes” on page 5-3 and “Which VLAN Is Primary?” on page 9-51.

5-2

Packet Time-To-Live (TTL). This paramet er specifies how long in seconds an outgoing packet should exist in the network. In most cases, the default setting (64 seconds) is adequate.

Configuring IP Addressing, Interface Access, and System Information

Timep Operation. Use this optional parameter if you want the switch to get its time information from another device operating as a Timep server. In its default Timep configuration, the switch attempts to get a Timep server address from a DHCP server. Other configuration options are to manually assign a Timep server address or to disable the Timep server feature.

IP Configuration

Just Want a Quick Start?

If you just want to give the switch an IP address so that it can communicate on your network, or if you are not using VLANs, SMC recommends that you use the Switch Setup screen to quickly configure IP addressing. To do so, do one of the following:

■ Enter setup at the CLI Manager level prompt.

SMC TigerSwitch 10/100# setup

■ Select 8. Run Setup in the Main Menu of the menu interface.

For more on using the Switch Setup screen, see the Installation Guide you received with the switch.

IP Addressing with Multiple VLANs

In the factory-default configuration, the switch has one, permanent default VLAN (named DEFAULT_VLAN) that includes all ports on the switch. In this state, when you assign an IP address and subnet mask to the switch, you are actually assigning the IP addressing to the DEFAULT_VLAN. You can rename the DEFAULT_VLAN, but you cannot change its VLAN ID number (VID) or remove it from the switch.

Notes ■ If multiple VLANs are configured, then each VLAN can have its own IP

address. This is because each VLAN operates as a separate broadcast domain and requires a unique IP address and subnet mask. A default gateway (IP) address for the switch is optional, but recommended. The primary VLAN is the VLAN used for stacking operation, as well as for determining the default gateway address, (packet) Time-To-Live (TTL), and Timep via DHCP or Bootp. (Other VLANs can also use DHCP or BootP to acquire IP addressing. However, the switch’s gateway, TTL, and TimeP values will be acquired through the primary VLAN only. In the default configuration, the default VLAN (named DEFAULT_VLAN) is the switch’s primary VLAN.However, with multiple VLANs assigned to the switch, you can select another VLAN to function as the primary VLAN. For more on VLANs, refer to “Port-Based Virtual LANs (Static VLANs)” on page 9-48.

Configuring IP Addressing, Interface Access, and System Information

IP Configuration

■ The IP addressing used in the switch should be compatible with your

network. That is, the IP address must be unique and the subnet mask must be appropriate for the IP network.

■ If you plan to connect to other networks that use globally administered

IP addresses, refer to “Globally Assigned IP Network Addresses” on page 5-14.

■ By default, the switch uses DHCP to acquire the IP address of the TimeP

server. If the switch does not have a manually configured Timep setting, then it attempts to get its TimeP setting through DHCP or Bootp through the primary VLAN.

■ The switch searches for the default gateway device through the primary

VLAN. By default, the DEFAULT_VLAN is the switch’s primary VLAN. However, you can use the CLI to select a different primary VLAN if more

Interface Access, and

Configuring IP Addressing,

than one VLAN exists on the switch. For more information, see “PortBased Virtual LANs (Static VLANs)” on page 9-48.

■ If you change the IP address through either Telnet access or the web

browser interface, the connection to the switch will be lost. You can reconnect by either restarting Telnet with the new IP address or entering the new address as the URL in your web browser.

IP Addressing in a Stacking Environment

If you are installing the switch into a stack management environment, entering an IP address may not be required. See “Stack Management” on page 9-2 for more information.

Menu: Configuring IP Address, Gateway, Time-To-Live (TTL), and Timep

Do one of the following:

■ To manually enter an IP address, subnet mask, set the IP Config parameter

How IP Addressing Affects Switch Operation

Without an IP address and subnet mask compatible with your network, the switch can be managed only through a direct terminal device connection to the Console RS-232 port. You can use direct-connect console access to take advantage of features that do not depend on IP addressing. However, to realize the full performance capabilities proactive networking offers through the switch, configure the switch with an IP address and subnet mask compatible with your network. The following table lists the general features available with and without a network-compatible IP address configured.

DHCP/Bootp Operation

Overview. DHCP/Bootp is used to provide configuration data from a DHCP or Bootp server to the switch. This data can be the IP address, subnet mask, default gateway, Timep Server address, and TFTP server address. If a TFTP server address is provided, this allows the switch to TFTP a previously saved configuratin file from the TFTP server to the switch. With either DHCP or Bootp, the servers must be configured prior to the switch being connected to the network.

Note The SMC6624M switch is compatible with both DHCP and Bootp servers.

The DHCP/Bootp Process. Whenever the IP Config parameter in the switch or in an individual VLAN in the switch is configured to DHCP/Bootp (the default), or when the switch is rebooted with this configuration:

5-10

Configuring IP Addressing, Interface Access, and System Information

IP Configuration

1. DHCP/Bootp requests are automatically broadcast on the local network. (The switch sends one type of request to which either a DHCP or Bootp server can respond.)

2. When a DHCP or Bootp server receives the request, it replies with a previously configured IP address and subnet mask for the switch. The switch also receives an IP Gateway address if the server has been configured to provide one. In the case of Bootp, the server must first be configured with an entry that has the MAC address of the switch. (To determine the switch’s MAC address, see appendix B, “MAC Address Management”. The switch properly handles replies from either type of server. If multiple replies are returned, the switch tries to use the first reply.)

Note If you manually configure a gateway on the switch, it will ignore any gateway

address received via DHCP or Bootp.

If the switch is initially configured for DHCP/Bootp operation (the default), or if it is rebooted with this configuration, it immediately begins sending request packets on the network. If the switch does not receive a reply to its DHCP/Bootp requests, it continues to periodically send request packets, but with decreasing frequency. Thus, if a DHCP or Bootp server is not available or accessible to the switch when DHCP/Bootp is first configured, the switch may not immediately receive the desired configuration. After verifying that the server has become accessible to the switch, reboot the switch to re-start the process immediately.

Configuring IP Addressing,

Interface Access, and

DHCP Operation. A significant difference between a DHCP configuration and a Bootp configuration is that an IP address assignment from a DHCP server is automatic. Depending on how the DHCP server is configured, the switch may receive an IP address that is temporarily leased. Periodically the switch may be required to renew its lease of the IP configuration. Thus, the IP addressing provided by the server may be different each time the switch reboots or renews its configuration from the server. However, you can fix the address assignment for the switch by doing either of the following:

■ Configure the server to issue an “infinite” lease.

■ Using the switch’s MAC address as an identifier, configure the server with

a “Reservation” so that it will always assign the same IP address to the switch. (For MAC address information, refer to appendix B, “MAC Address Management”.)

For more information on either of these procedures, refer to the documentation provided with the DHCP server.

5-11

Configuring IP Addressing, Interface Access, and System Information

IP Configuration

Bootp Operation. When a Bootp server receives a request it searches its Bootp database for a record entry that matches the MAC address in the Bootp request from the switch. If a match is found, the configuration data in the associated database record is returned to the switch. For many Unix systems, the Bootp database is contained in the /etc/bootptab file. In contrast to DHCP operation, Bootp configurations are always the same for a specific receiving device. That is, the Bootp server replies to a request with a configuration previously stored in the server and designated for the requesting device.

Bootp Database Record Entries. A minimal entry in the Bootp table file /etc/bootptab to update an IP address and subnet mask to the switch or a VLAN configured in the switch would be similar to this entry:

An entry in the Bootp table file /etc/bootptab to tell the switch or VLAN where to obtain a configuration file download would be similar to this entry:

Network Preparations for Configuring DHCP/Bootp

In its default configuration, the switch is configured for DHCP/Bootp operation. However, the DHCP/Bootp feature will not acquire IP addressing for the switch unless the following tasks have already been completed:

■ For Bootp operation:

• A Bootp database record has already been entered into an appropriate

Bootp server.

• The necessary network connections are in place

• The Bootp server is accessible from the switch

■ For DHCP operation:

• A DHCP scope has been configured on the appropriate DHCP server.

• The necessary network connections are in place

• A DHCP server is accessible from the switch

Configuring IP Addressing,

Interface Access, and

Note Designating a primary VLAN other than the default VLAN affects the switch’s

use of information received via DHCP/Bootp. For more on this topic, see “Which VLAN Is Primary?” on page 9-51.

After you reconfigure or reboot the switch with DHCP/Bootp enabled in a network providing DHCP/Bootp service, the switch does the following:

■ Receives an IP address and subnet mask and, if configured in the server,

a gateway IP address and the address of a Timep server.

■ If the DHCP/Bootp reply provides information for downloading a config-

uration file, the switch uses TFTP to download the file from the designated source, then reboots itself. (This assumes that the switch or VLAN has connectivity to the TFTP file server specified in the reply, that the configuration file is correctly named, and that the configuration file exists in the TFTP directory.)

No: The port will not operate, even if properly connected in a network. Use this setting, for example, if the port needs to be shut down for diagnostic purposes or while you are making topology changes.

Up: The port senses a linkbeat. Down: The port is not enabled, has no cables connected, or is experiencing a network error. For

troubleshooting information, see the Installation Guide you received with the switch. See also chapter 11, “Troubleshooting” (in this manual).

10/100Base-T ports:

• Auto (default): Senses speed and negotiates with the port at the other end of the link for data transfer operation (half-duplex or full-duplex).

Note: Ensure that the device attached to the port is configured for the same setting that you select here. Also, if “Auto” is used, the device to which the port is connected must operate in compliance with the IEEE 802.3u “Auto Negotiation” standard for 100Ba se-T networks. If the other device does not comply with the 802.3u standard, or is not set to Auto, then the port configuration on the switch must be manually set to match the port configuration on the other device.

To see what the switch negotiates for the Auto setting, use the CLI show interfaces command or the “ 3. Port Status” option under “1. Status and Counters” in the menu interface.

• Auto-10: Allows the port to negotiate between half-duplex (HDx) and full-duplex (FDx) while keeping speed at 10 Mbps. Also negotiates flow control (enabled or disabled). SMC recommends Auto-10 for links between 10/100 autosensing ports connected with Cat 3 cabling. (Cat 5 cabling is required for 100 Mbps links.).

From the CLI, you can configure and view all port parameter settings and view all port status indicators.

Using the CLI To View Port Status. Use the following commands to display port status and configuration:

■ show interfaces: Lists the full status and configuration for all ports on the

switch.

■ show interface config: Lists a subset of the data shown by the show

interfaces command (above); that is, only the enabled/disabled, mode, and flow control status for all ports on the switch.

Viewing Port Status and Configuring Port Parameters

Using the CLI To Configure Ports. You can configure one or more of the following port parameters. For details on each option, see Table 6-1 on page 6-2.

Syntax: [no] interface <[ethernet] port-list>

Note that in the above syntax you can subsitute an “int” for “interface” and an “e” for “ethernet”; that is int e <port-list>.

For example, to configure ports 1 through 4 and port 7 for 100Mbps full-duplex with a broadcast limit of 20%, you would enter this command:

SMC TigerSwitch 10/100(config)# int e 1-4,7 speed-duplex 100-full

broadcast-limit 20

Similarly, to configure a single port with the settings in the above command, you could either enter the same command with only the one port identified, or go to the context level for that port and then enter the command. For example, to enter the context level for port 7 and then configure that port for 100FDx with a broadcast limit of 20%:

Optimizing Port Usage

SMC TigerSwitch 10/100(config)# int e 7 SMC TigerSwitch 10/100(eth-7)# speed-duplex 100-full broadcast-limit 20

If port 8 was disabled, and you wanted to enable it and configure it for 100FDx with a broadcast limit of 20%, with flow-control active and a broadcast limit of 20%, you could do so with either of the following command sets.

■ This command enables and configures port 8 from the config level:

SMC TigerSwitch 10/100(config)# interface e 8 enable speed-duplex 100-full broadcast-limit 20 flow-control

■ These two commands select the context level for port 8 and then apply

all of the configuration commands to port 8:

SMC TigerSwitch 10/100(config)# int e 8 SMC TigerSwitch 10/100(eth-8)# enable speed-duplex 100-full flow-control broadcast-limit 20
