A waiver by Enterasys of a breach of any of the terms and conditions of this Agreement must be in writing and will not be construed as a waiver of any subsequent breach of such term or condition. Enterasys’ failure to enforce a term upon Your breach of such term shall not be construed as a waiver of Your breach or prevent enforcement on any other occasion.

iii

13. SEVERABILITY. In the event any provision of this Agreement is found to be invalid, illegal or unenforceable, the validity, legality and enforceability of any of the remaining provisions shall not in any way be affected or impaired thereby, and that provision shall be reformed, construed and enforced to the maximum extent permissible. Any such invalidity, illegality, or unenforceability in any jurisdiction shall not invalidate or render illegal or unenforceable such provision in any other jurisdiction.

14. TERMINATION. Enterasys may terminate this Agreement immediately upon Your breach of any of the terms and conditions of this Agreement. Upon any such termination, You shall immediately cease all use of the Program and shall return to Enterasys the Program and all copies of the Program.

For information about configuring Telnet settings, refer to “Starting and Configuring Telnet” on page 3-32.

Refer to the instructions included with the Telnet application for information about establishing a Telnet session.

Logging In

By default, the Enterasys C3 switch is configured with three user login accounts—ro for Read-Only access, rw for Read-Write access, and admin for super-user access to all modifiable parameters. The default password is set to a blank string. For information on changing these default settings, refer to “User Account and Password Management” on page 5-1.

Using the Command Line Interface

steps listed in “Using a Default User Account” on page 1-7, or

If this is the first time you are logging in to the Enterasys C3 switch, or if the default user accounts have not been administratively changed, proceed as follows:

1. At the login prompt, enter one of the following default user names:

– ro for Read-Only access.

– rw for Read-Write access.

– admin for Super User access.

2. Press ENTER. The Password prompt displays.

3. Leave this string blank and press ENTER. The switch information and prompt displays as shown in Figure 1-1.

Using an Administratively Configured User Account

If the switch’s default user account settings have been changed, proceed as follows:

1. At the login prompt, enter your administratively-assigned user name and press ENTER.

2. At the Password prompt, enter your password and press ENTER.

The notice of authorization and the prompt displays as shown in Figure 1-1.

Note: Users with Read-Write (rw) and Read-Only access can use the set password command (page 5-9) to change their own passwords. Administrators with Super User (su) access can use the set system login command (page 5-6) to create and change user accounts, and the set

password command to change any local account password.

Getting Help with CLI Syntax

The Enterasys C3 switch allows you to display usage and syntax information for individual commands by typing help or ? after the command.

CLI Command Defaults Descriptions

Each command description in this guide includes a section entitled “Defaults” which contains different information from the factory default settings on the switch described in Table 1 -1 . The section defines CLI behavior if the user enters a command without typing optional parameters (indicated by square brackets [ ]). For commands without optional parameters, the defaults section lists “None”. For commands with optional parameters, this section describes how the CLI responds if the user opts to enter only the keywords of the command syntax. Figure 1-2 provides an example.

Defaults

If port-string is not specified, status information for all ports will be displayed.

CLI Command Modes

Each command description in this guide includes a section entitled “Mode” which states whether the command is executable in Admin (Super User), Read-Write, or Read-Only mode. Users with Read-Only access will only be permitted to view Read-Only (show) commands. Users with ReadWrite access will be able to modify all modifiable parameters in set and show commands, as well as view Read-Only commands. Administrators or Super Users will be allowed all Read-Write and Read-Only privileges, and will be able to modify local user accounts. The Enterasys C3 switch indicates which mode a user is logged in as by displaying one of the following prompts:

Performing Keyword Lookups

Entering a space and a question mark (?) after a keyword will display all commands beginning with the keyword. Figure 1-3 shows how to perform a keyword lookup for the show snmp command. In this case, four additional keywords are used by the show snmp command. Entering a space and a question mark (?) after any of these parameters (such as show snmp community) will display additional parameters nested within the syntax.

Note: At the end of the lookup display, the system will repeat the command you entered without the ?.

Displaying Scrolling Screens

If the CLI screen length has been set using the set length command as described on page 3-24, CLI output requiring more than one screen will display --More-- to indicate continuing screens. To display additional screen output:

• Press any key other than ENTER to advance the output one screen at a time.

• Press ENTER to advance the output one line at a time.

The example in Figure 1-5 shows how the show mac command indicates that output continues on more than one screen.

About Enterasys C3 Switch Operation in a Stack

The Enterasys C3 products are stackable switches that can be adapted and scaled to help meet your network needs. These switches provide a management platform and uplink to a network backbone for a stacked group of up to eight Enterasys C3 switches.

Note: You can mix SecureStack C2 and C3 switches in a single stack, although only the lowest common denominator of functionality will be supported in a mixed stack. Refer to “Issues Related to

Mixed Type Stacks” on page 2-4 for information about configuring a mixed stack.

Once installed in a stack, the switches behave and perform as a single switch product. As such, you can start with a single unit and add more units as your network expands. You can also mix different products in the family in a single stack to provide a desired combination of port types and functions to match the requirements of individual applications. In all cases, a stack of units performs as one large product, and is managed as a single network entity.

When switches are installed and connected as described in your Enterasys C3 Installation Guide, the following occurs during initialization:

• The switch that will manage the stack is automatically established. This is known as the manager switch.

• All other switches are established as members in the stack.

• The hierarchy of the switches that will assume the function of backup manager is also determined in case the current manager malfunctions, is powered down, or is disconnected from the stack.

Enterasys C3 Configuration Guide 2-1

Installing a New Stackable System of Up to Eight Units

• The console port on the manager switch remains active for out-of-band (local) switch management, but the console port on each member switch is deactivated. This enables you to set the IP address and system password using a single console port. Now each switch can be configured locally using only the manager’s console port, or inband using a remote device and the CLI set of commands described in this section.

Once a stack is created (more than one switch is interconnected), the following procedure occurs:

1. By default, unit IDs are arbitrarily assigned on a first-come, first-served basis.

2. Unit IDs are saved against each module. Then, every time a board is power-cycled, it will initialize with the same unit ID. This is important for port-specific information (for example: ge.4.12 is the 12th Gigabit Ethernet port on Unit # 4).

3. The management election process uses the following precedence to assign a management switch:

a. Previously assigned / elected management unit

b. Management assigned priority (values 1-15)

c. Hardware preference level

d. Highest MAC Address

Use the following recommended procedures when installing a new stackable system or adding a new unit to an existing stack.

Important

The following procedures assume that all units have a clean configuration from manufacturing. When adding a new unit to an already running stack, it is also assumed that the new unit is using the same firmware image version as other units in the stack.

Installing a New Stackable System of Up to Eight Units

Use the following procedure for installing a new stack of up to eight units out of the box.

1. Before applying power, make all physical connections with the stack cables as described in your Enterasys C3 Installation Guide.

2. Once all of the stack cables have been connected, individually power on each unit from top to bottom.

Notes: Ensure that each switch is fully operational before applying power to the next switch. Since unit IDs are assigned on a first-come, first-served basis, this will ensure that unit IDs are ordered sequentially.

Once unit IDs are assigned, they are persistent and will be retained during a power cycle to any or all of the units.

3. (Optional) If desired, change the management unit using the set switch movemanagement command as described in “set switch movemanagement” on page 2-10.

4. Once the desired master unit has been selected, reset the system using the reset command (page 3-47).

5. After the stack has been configured, you can use the show switch unit command (page 2-5) to physically identify each unit. When you enter the command with a unit number, the MGR LED of the specified switch will blink for 10 seconds. The normal state of this LED is off for member units and steady green for the manager unit.

2-2 Configuring Switches in a Stack

Installing Previously-Configured Systems in a Stack

If member units in a stack have been previous members of a different stack, you may need to configure the renumbering of the stack as follows:

1. Stack the units in the method desired, and connect the stack cables.

2. Power up only the unit you wish to be manager.

3. Once the management unit is powered up, log into the CLI, and use the show switch command as described in “show switch” on page 2-5 to display stacking information.

4. Clear any switches which are listed as “unassigned” using the clear switch member command as described in “clear switch member” on page 2-11.

5. Power up the member of the stack you wish to become unit 2. Once the second unit is fully powered, the COM session of the CLI will state that a new CPU was added.

6. Use the show switch command to redisplay stacking information.

a. If the new member displays as unit 2, you can proceed to repeat this step with the next

unit.

b. If the new member displays a different unit number, you must:

(1) Renumber the stack using the set switch renumber command as described in “set

switch” on page 2-8, then

(2) Clear the original unit number using the clear switch member command.

7. Repeat Step 6 until all members have been renumbered in the order you desire.

8. After the stack has been reconfigured, you can use the show switch unit command (“show

switch” on page 2-5) to physically confirm the identity of each unit. When you enter the

command with a unit number, the MGR LED of the specified switch will blink for 10 seconds. The normal state of this LED is off for member units and steady green for the manager unit.

Adding a New Unit to an Existing Stack

Use the following procedure for installing a new unit to an existing stack configuration. This procedure assumes that the new unit being added has a clean configuration from manufacturing and is running the same firmware image version as other units in the stack.

1. Ensure that power is off on the new unit being installed.

2. Use one of the following methods to complete stack cable connections:

– If the running stack uses a daisy chain topology, make the stack cable connections from

the bottom of the stack to the new unit (that is, STACK DOWN port from the bottom unit of the running stack to the STACK UP port on the new unit).

– If the running stack uses a ring stack topology, break the ring and make the stack cable

connections to the new unit to close the ring.

3. Apply power to the new unit.

Creating a Virtual Switch Configuration

You can create a configuration for a Enterasys C3 switch before adding the actual physical device to a stack. This preconfiguration feature includes configuring protocols on the ports of the “virtual switch.”

Enterasys C3 Configuration Guide 2-3

Considerations About Using Clear Config in a Stack

To create a virtual switch configuration in a stack environment:

1. Display the types of switches supported in the stack, using the show switch switchtype command (page 2-7).

2. Using the output of the show switch switchtype command, determine the switch index (SID) of the model of switch being configured.

3. Add the virtual switch to the stack using the set switch member command (page 2-11). Use the SID of the switch model, determined in the previous step, and the unit ID that you want to assign to this switch member.

4. Proceed to configure the ports of the virtual switch as you would do for physically present devices.

Note: If you preconfigure a virtual switch and then add a physical switch of a different type to the stack as that unit number, any configured functionality that cannot be supporte d on th e ph ysi ca l switch will cause a configuration mismatch status for that device and the ports of the new device will join detached. You must clear the mismatch before the new device will properly join the stack.

Considerations About Using Clear Config in a Stack

When using the clear config command (page 3-49) to clear configuration parameters in a stack, it is important to remember the following:

•Use clear config to clear config parameters without clearing stack unit IDs. This command WILL NOT clear stack parameters or the IP address and avoids the process of renumbering the stack.

•Use clear config all when it is necessary to clear all config parameters, including stack unit IDs and switch priority values. This command will not clear the IP address nor will it remove an applied advanced feature license.

•Use clear ip address to remove the IP address of the stack.

•Use clear license to remove an applied license from a switch.

Configuration parameters and stacking information can also be cleared on the master unit only by selecting the “restore configuration to factory defaults” option from the boot menu on switch startup. This selection will leave stacking priorities on all other units.

Issues Related to Mixed Type Stacks

Feature Support

Because the SecureStack C2 and C3 switches have different hardware architectures, the functionality supported by the two switch types is different. When the two types of switches are mixed in a stack, the functionality supported will be the lowest common denominator of features supported on all platforms. Refer to the firmware Release Notes for information about supported features.

Configuration

Common Firmware Version

Mixed stacking is supported by SecureStack C2 firmware version 5.02.xx.xxxx only. You can install the C2 firmware first, with the C3 switch in stand-alone mode, or you can add the C3 switch to the

2-4 Configuring Switches in a Stack

Stacking Configuration and Management Commands

stack and then copy the C2 firmware to the C3 switch using the set switch copy-fw command (page 2-9). After copying the C2 firmware to the C3 switch, you must reset the stack.

Switch Manager

It is recommended that a SecureStack C3 switch be made the manager of a mixed stack. Use the set

switch movemanagement command (page 2-10) to change the manager unit.

3-26 Basic Configuration

Downloading a Firmware Image

Parameters

enable Enables VT100 terminal mode.

disable Disables VT100 terminal mode.

Defaults

VT100 terminal mode is disabled by default.

Mode

Switch mode, read-write, when security profile = normal.

Switch mode, super-user, when security profile = C2.

Usage

VT100 mode is required to support automatic console session termination on removal of the serial connection (vs. timeout). This mode requires that the attached console device be running VT100 terminal emulation.

In VT100 mode, the switch polls for device status (using the appropriate VT100 escape sequence) to detect an attached device, which requires that the attached device be running VT100 terminal emulation. At any time, if the switch fails to get a status reply, an existing console session is terminated.

On receipt of the first polled status response, the login banner is displayed if it is configured.

Example

This example enables VT100 mode.

C3(su)->set console vt100 enable

Downloading a Firmware Image

You can upgrade the operational firmware in the Enterasys C3 switch without physically opening the switch or being in the same location. There are two ways to download firmware to the switch:

• Via TFTP or SFTP download. This procedure uses a TFTP or SFTP server connected to the network and downloads the firmware using the TFTP or SFTP protocol. For details on how to perform a TFTP or SFTP download using the copy command, refer to “copy” on page 3-41. For information on setting TFTP timeout and retry parameters, refer to “set tftp timeout” on page 3-43 and “set tftp retry” on page 3-44.

• Via the serial (console) port. This procedure is an out-of-band operation that copies the firmware through the serial port to the switch. It should be used in cases when you cannot connect the switch to perform the in-band copy download procedure via TFTP. Serial console download has been successfully tested with the following applications:

– Tera Term Pro Version 2.3

Any other terminal applications may work but are not explicitly supported.

The C3 switch allows you to download and store dual images. The backup image can be downloaded and selected as the startup image by using the commands described in this section.

Enterasys C3 Configuration Guide 3-27

Downloading a Firmware Image

C5(rw)->show boot system Current system image to boot: c5-series_06.61.xx C5(rw)->

Reverting to a Previous Image

In the event that you need to downgrade to a previous version of code, you can do so by completing the following steps as described in this chapter.

Caution: Before reverting to a previous image, always back up your configuration by saving it to a file (show config outfile on page 3-39). You can then copy the file to a remote location (copy on page 3-41).

Note: You will not be able to peform these steps remotely unless you have remote console support.

1. Save your running configuration with the save config command.

2. Make a copy of the current configuration with the show config outfile configs/filename command. Use the dir command to confirm that the file was created.

3. If desired, copy the file to a remote TFTP server with the copy command:

copy configs/filename tftp://server_ipaddr/filename

4. Load your previous version of code on the device, as described in “Downloading a Firmware

Image” (page 3-27).

5. Set this older version of code to be the boot code with the set boot system command (page 3-

31). When the system asks if you want to reset the device, specify no (n).

6. Reload the saved configuration onto the device with the configure command, described on page 3-40.

7. Reboot the system using the reset command (page 3-47).

Caution: If you do not follow the steps above, you may lose remote connectivity to the switch.

Managing Switch Configuration and Files

Configuration Persistence Mode

The default state of configuration persistence mode is “auto,” which means that when CLI configuration commands are entered, or when a configuration file stored on the switch is executed, the configuration is saved to NVRAM automatically at the following intervals:

• On a standalone unit, the configuration is checked every two minutes and saved if there has been a change.

• On a stack, the configuration is saved across the stack every 5 minutes if there has been a change.

If you want to save a running configuration to NVRAM more often than the automatic intervals, execute the save config command and wait for the system prompt to return. After the prompt returns, the configuration will be persistent.
