Changing the Login Password

Change the login password for admin user sessions by following the steps below:

1Be sure that you have logged into the switch as user type admin (see“Logging in to the Switch” on page 14).

2Enter the keyword password and pressEnter.

3Enter your new password at the prompt (refer to the note below).

Note. Typically, the password should be a string of nonrepeating characters. The switch’s authentication software uses the first occurrence of the character series to uniquely identify the password. For example, the passwordengrengr is the same asengr. A better password might beengr2735.

4 You will be prompted tore-enterthe password. Enter the password a second time.

Note. Be sure to remember or securely record all new passwords; overriding configured passwords on OmniSwitch 6850 Series switches is restricted.

New password settings are automatically saved in real time to the local user database; the user is not required to enter an additional command in order to save the password information. Also note that new password information is retained following a reboot.

All subsequent login sessions—includingthose through the consoleport—willrequire the new password in order to access the switch.

User Accounts. The switch allows a maximum of 50 user accounts in the local user database. For information on creating additional user types and assigning individual passwords, refer to the “Managing Switch User Accounts” chapter of yourOmniSwitch 6800/6850/9000 Switch Management Guide.

Setting the System Time Zone

The switch’s default time zone is UTC (also referred to as Greenwich Mean Time).

If you require a time zone that is specific to your region—orif you need to enable Daylight Savings Time (DST) on theswitch—youcan configure these settings via the

system timezone and system daylight savings time commands. For example, to set the system clock to run on Pacific Standard Time, enter the following command:

->system timezone pst

To enable Daylight Savings Time, enter the following command:

->system daylight savings time enable

Many other time zone variables are supported. For detailed information on configuring a time zone for the switch, refer to your OmniSwitch 6800/6850/9000 Switch Management Guide.

Setting the Date and Time

Set the current time for the switch by entering system time, followed by the current time inhh:mm:ss. For example:

->system time 18:35:00

The switch uses a 24-hourclock; the time value shown in the above example would set the time to 6:35 PM.

To set the current date for the switch, enter system date, followed by the current date inmm/dd/yyyy. For example:

->system date 06/27/2005

Setting Optional System

Information

This section provides information on configuring optional system parameters, including:

the switch’s administrative contact

a system name

the switch’s physical location

Specifying an Administrative Contact

An administrative contact is the person or department in charge of the switch. If a contact is specified, users can easily find the appropriate network administrator if they have questions or comments about the switch.

To specify an administrative contact, enter system contact, followed by a text string of up to 254 characters. If you include spaces between words in the text string, be sure to enclose the string in quotes (" ").

For example:

->system contact "JSmith js@company.com"

Specifying a System Name

The system name is a simple, user-definedtext description for the switch.

To specify a system name, enter system name, followed by a text description of up to 19 characters.

Note. Youcannot include spaces between words when entering a system name.

For example:

->system name EngSwitch3

Specifying the Switch’s Location

It is recommended that you use a physical labeling system for locating and identifying your switch(es). Examples include placing a sticker or placard with a unique identifier (e.g., the switch’s default IP address) on each chassis.

However, if no labeling system has been implemented or if you need to determine a switch’s location from a remote site, entering a system location can be very useful.

To specify a system location, enter system location, followed by a text description of up to 254 characters. If you include spaces between words in the text string, be sure to enclose the string in quotes (" ").

For example:

->system location "NMSLab--NERack"

Viewing and Saving Changes

To view your current changes, enter show system at the CLI prompt.

Once you have configured this basic switch information, save your changes by entering write memory at the CLI command prompt.

When the write memory command is entered, changes are automatically saved to the main configuration file (boot.cfg) and placed in the/flash/working directory. For more information on theboot.cfg file, refer topage 20.

Note. If the switch reboots following awrite memory command entry, the switch will run from the/flash/certified directory. As a result, subsequent configuration changes cannot be saved using thewrite memory command until the switch is once again running from the/flash/working directory. Seepage 22 for important information on these directories.

This completes the initial configuration process. Your OmniSwitch 6850 Series switch is now ready for additional configuration and network operation. Refer to the following sections for more information on using your switch, as well as additional built-infeatures.

For stacked configurations, be sure to refer to the OmniSwitch 6850 Series Hardware Users Guide.

Files and Directories

Boot and Image Files

Although the flash memory on OmniSwitch 6850 Series switches can contain many file types (e.g., log and snapshot files), there are four specific file types that provide key switch and network functions. These files include the boot.cfg file,boot.params file,boot.slot.cfg file, and image (.img) files.

boot.params File

The boot.params file provides IP address, gateway, and mask information for the switch. This information is required for Ethernet connections to the switch.

This file also contains default console port parameters (baud rate, etc.) and can be modified via the modify boot parameters CLI command.

In order to be read by the switch, the boot.params file must be placed in the/flash directory. If the file is deleted for any reason, a newboot.params file will be automatically generated on the next system boot. However, alluser-configuredinformation, such as IP address, gateway, and mask information, will be lost. Therefore, it is recommended that you keep a backup copy of this file at all times.

boot.cfg File

The boot.cfg file stores your network configuration parameters. When you first boot the switch, noboot.cfg file is present. This file is automatically generated when you first issue awrite memory command to save your configuration changes. The file is then automatically placed in the

/flash/working directory.

Important. Your switch must be running from the/flash/working directory in order to save changes to theboot.cfg file. Refer to“Working and Certified Directories” on page 22 for more information.

Once the configuration parameters stored in the boot.cfg file are considered tested and reliable, the file can be copied to the/flash/certified directory and become part of the “last known good” software for the switch.

If all copies of this file are deleted and a system boot occurs, your network configuration will be lost. Therefore, it is recommended that you keep a backup copy of this file at all times.

20 Files and Directories

Image Files

Image files (those files with .img extensions) contain an executable code that provides support for the system, Ethernet ports, and network functions. In other words, they serve as essential drivers for switch and network operations.

Although these files may be backed up to the root flash directory or any user-definedsubdirectory, they must be present in the/flash/working and/flash/certified directories for the switch to operate and pass traffic.

If you delete all copies of an image file, you will be required to contact Alcatel-LucentCustomer Support for replacements. Therefore, it is recommended that you keep backup copies on your computer’s hard drive or alocally-accessibleserver.

For a complete list of OmniSwitch 6850 Series image files, along with their functions, refer to the following table:

Working and Certified

Directories

OmniSwitch 6850 Series switches offer flash memory with

8 MB base ROM space and 64 MB extended ROM. This memory is used to store files, including boot and image files, that are used for switch operations.

The /flash directory contains two subdirectories:/working and/certified. These directories work together to provide theimage rollback resiliency feature. Image rollback allows the switch to return to a prior “last known good” version of software in the event of a system software problem.

Working Directory

Working Directory

Intended for: Files that are being configured and tested. Once these files are considered valid and reliable, they can be copied to the Certified directory.

On reload: If the Working and Certified directories are identical, the switch will automatically run from software in this directory. If the two directories are not identical, you can instruct the switch to run from the Working directory by issuing the reload working command.

Saving changes: You can save configuration changes to the Working directory via the write memory command.

The /flash/working directory is intended for software that is still being configured for your network. Changes made while configuring your switch are saved to theboot.cfg file in the

/flash/working directory.

Once the /flash/working directory’s configuration and image files areroad-testedand considered valid and reliable for your network, they can be copied to the/flash/certified directory.

22 Files and Directories

June 2007

Certified Directory

Certified Directory

Intended for: Reliable, Tested configuration and image files. The switch will roll back to this software in the event of a system software error.

On reload: By default, the switch will use the software in this directory if there are any differences between the Working and Certified directories.

Saving changes: You cannot save configuration changes to the Certified directory. To save your changes, be sure that your switch is operating from the Working directory.

The software in the /flash/certified directory should be treated as the “gold master” for the switch. When you place configuration and image files in this directory, you are “certifying” them as tested and reliable. If the switch is running from the/flash/working directory and experiences a software problem, it will “roll back” to the last known good software in the/flash/certified directory on the next reboot.

How can I tell which directory the switch is currently using?

When you first boot the switch, the /flash/working directory is used; this allows you to save your initial configuration changes to theboot.cfg file. However, subsequent boots may result in your switch running from the/flash/certified directory. Therefore, verifying the current running directory is a key step any time you are configuring or monitoring the switch.

View the switch’s current running directory by entering the show running-directory command. For example:

->showrunning-directory

 

CONFIGURATION STATUS

: PRIMARY,

Running CMM

CMM Mode

: DUAL CMMs,

Current CMM Slot

: 1,

Running configuration

: WORKING,

Certify/Restore Status

: CERTIFY NEEDED

SYNCHRONIZATION STATUS

: SYNCHRONIZED,

Flash Between CMMs

Running Configuration

: NOT AVAILABLE,

Stacks Reload on Takeover: ALL STACKs (SW Activation)

In this example, the switch is using the /flash/working directory. For more information on theshow running-directory command output, refer to the “CMM Commands” chapter in theOmniSwitch CLI Reference Guide.

Files and Directories 23

Can I save changes to the Certified directory?

No. The /flash/certified directory is intended to store only tested, reliable configuration and image files. Configuration changes must be saved to theboot.cfg file in the/flash/working directory. Once those changes have been roadtested, the contents of the/flash/working directory can be copied to the/flash/certified directory via the

copy working certified command.

What happens when the switch boots?

During the boot process, the switch compares the contents of the /flash/working and/flash/certified directories. Based on this comparison, the switch determines which directory to use as its running software.

Working and Certified Are Identical

If the software in the /flash/workingand /flash/certifieddirectories are completely identical, the switch considers the software in both directories to be equally reliable. In this case, the switch will run from the /flash/workingdirectory.
