Rack-Mounting the Switch
recommendations before installing.
Refer to the important guidelines below before installing the
OmniSwitch chassis in a rack.
Rack Mounting Steps
• It is recommended that two people install the switch in
the rack—one person to hold the chassis and position it
in the rack, and a second person to secure the chassis to
the rack using attachment screws (not supplied).
To rack-mount the switch, follow the steps below:
Note. Rack-mount flanges may come factory-installed in
some cases. If this is the case, skip steps 1 and 2 below.
• Alcatel-Lucent provides two rack-mount flanges with
each OmniSwitch 6850 Series switch. These flanges
support standard 19-inch rack mount installations.
These flanges must be attached to the chassis before
the switch can be rack mounted.
1 Align the holes in the provided rack-mount flanges
with the four threaded holes in the OmniSwitch chassis.
These threaded holes are located in the left and right sides
of the chassis, near the front panel.
Note. If you are installing the switch in a 23-inch wide
rack, Alcatel-Lucent offers optional 23-inch rack-mount-
ing hardware. For more information, contact your Alcatel-
Lucent representative.
2 Attach the flanges to the chassis using the provided
Phillips-head screws. Be sure to tighten each of the screws
firmly using a Phillips screwdriver.
5
• Alcatel-Lucent does not provide rack-mount screws.
Use the screws supplied by the rack vendor.
46
• To prevent a rack from becoming top heavy, it is
recommended that you install heavier equipment at the
bottom of the rack whenever possible.
• If you are installing the switch in a relay rack, be sure
to install and secure the rack as per the rack manufac-
turer’s specifications.

3 After the rack-mount flanges are secured to the chas-
sis, mark the holes on the rack where the switch is to be
installed.
7 Once the screws at the bottom of each flange are
secure, install the remaining two rack-mount screws. Be
sure that all screws are securely tightened.
4 Lift and position the switch until the rack-mount
flanges are flush with the rack post.
8 If you are installing multiple switches in a rack to form
a stacked configuration, repeat steps 1 through 7 for all
switches in the stack.
5 Align the holes in the flanges with the rack holes that
were marked in step 3.
Note. When rack mounting multiple switches in a stacked
configuration, be sure to place all switches in vertically-
adjacent rack positions. This will ensure that all required
stacking cables will have adequate length for the installa-
tion.
6 Once the holes are aligned, insert a rack-mount screw
(not provided) through the bottom hole of each flange.
Tighten both screws until they are secure.
Attaching the Switch to the Rack
Note. Be sure to install the screws in the bottom hole of
each flange, as shown, before proceeding.

Your First Login Session
Once the switch or stack has successfully booted and you have
accessed your computer’s terminal emulation software via the
console port, you are ready to log in to the switch’s Command
Line Interface (CLI) and configure basic information.
Logging in to the Switch
When you first log in to the switch or stack, you will be
prompted for a login (i.e., user) name and password. During
this first login session, only one user name option and one
password option is available:
Complete the following steps during your first login session:
• Log in to the switch or stack
• Unlock session types
• Login (i.e., user name)—admin
• Password—switch
• Change the login password
• Set the date and time
To log in to the switch or stack, enter admin at the login
prompt:
login: admin
• Set optional system information
• Save your changes
Next, enter the factory default password, switch, at the pass-
word prompt:
password: switch
Note. You must be connected to the switch via the console
port before initiating your first login session. If you are
using OmniSwitch 6850 Series switches in a stacked
configuration, you must be connected to the console port
of the stack’s primary switch.

Assigning an IP Address to the
Switch
Assigning an IP address to your OmniSwitch 6850 Series
switch is an important step in the setup process.
Welcome to the Alcatel-Lucent OmniSwitch 6850 Series
Software Version 6.1.5.281.R01 Development, March 16, 2007.
Copyright(c), 1994-2007 Alcatel-Lucent All Rights reserved.
Remote sessions such as Telnet, FTP, and WebView require
an IP address. The IP address for these session types serves as
a destination point for the remote session. Therefore, before
the switch can support any remote login sessions, a valid IP
address must be configured.

More Information on User Accounts. A user account
includes a login name, password, and user privileges.
Privileges determine whether the user has read or write
access to the switch and which commands the user is
authorized to execute.
To assign an IP address to a switch, simply assign an IP
address to the switch’s default VLAN 1 by entering the
ip interface command at the CLI prompt. Be sure that the
command begins with the command syntax:
-> ip interface address
For detailed information on setting up and modifying user
accounts and user privileges, refer to the “Managing
Switch User Accounts” chapter of your OmniSwitch 6800/

Unlocking Session Types
Unlocking Specified Session Types
Security is a key feature on OmniSwitch 6850 Series switches.
As a result, when you access the switch for the first time, you
must use a direct console port connection. All other session
types (Telnet, FTP, WebView, SNMP, etc.) are “locked out”
until they are manually unlocked by the user.
You can also unlock session types on a one-by-one basis. For
example, to unlock Telnet sessions only, enter the following
command:
-> aaa authentication telnet local
The CLI command used to unlock session types is
aaa authentication.
To unlock WebView (HTTP) sessions only, enter the follow-
ing command:
-> aaa authentication http local
Note. When you unlock session types, you are granting
switch access to non-local sessions (e.g., Telnet). As a
result, users who know the correct user login and pass-
word will have remote access to the switch. For more
information on switch security, refer to the “Managing
Switch User Accounts” chapter of your OmniSwitch 6800/
6850/9000 Switch Management Guide.
You cannot specify more than one session type in a single
command line. However, you can still unlock multiple session
types by using the aaa authentication command in succes-
sion. For example:
-> aaa authentication http local
-> aaa authentication telnet local
-> aaa authentication ftp local
Unlocking All Session Types
To unlock all session types, enter the following command
syntax at the CLI prompt:
-> aaa authentication default local

Changing the Login Password
All subsequent login sessions—including those through the
console port—will require the new password in order to access
the switch.
Change the login password for admin user sessions by follow-
ing the steps below:
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 your OmniSwitch 6800/6850/9000 Switch
Management Guide.
1 Be sure that you have logged into the switch as user
2 Enter the keyword password and press Enter.
3 Enter your new password at the prompt (refer to the
note below).
Note. Typically, the password should be a string of non-
repeating characters. The switch’s authentication software
uses the first occurrence of the character series to uniquely
identify the password. For example, the password
engrengr is the same as engr. A better password might be
engr2735.
4 You will be prompted to re-enter the 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 informa-
tion. Also note that new password information is retained
following a reboot.

Setting the System Time Zone
To set the current date for the switch, enter system date,
followed by the current date in mm/dd/yyyy. For example:
The switch’s default time zone is UTC (also referred to as
Greenwich Mean Time).
-> system date 06/27/2005
If you require a time zone that is specific to your region—or if
you need to enable Daylight Savings Time (DST) on the
switch—you can 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:
Setting Optional System
Information
This section provides information on configuring optional
system parameters, including:
-> system timezone pst
• the switch’s administrative contact
• a system name
To enable Daylight Savings Time, enter the following
command:
• the switch’s physical location
-> system daylight savings time enable
Specifying an Administrative Contact
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.
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 ques-
tions or comments about the switch.
Setting the Date and Time
Set the current time for the switch by entering system time,
followed by the current time in hh:mm:ss. For example:
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 (" ").
-> system time 18:35:00
The switch uses a 24-hour clock; the time value shown in the
above example would set the time to 6:35 PM.
For example:
-> system contact "JSmith [email protected]"

Specifying a System Name
Viewing and Saving Changes
The system name is a simple, user-defined text description for
the switch.
To view your current changes, enter show system at the CLI
prompt.
To specify a system name, enter system name, followed by a
text description of up to 19 characters.
Once you have configured this basic switch information, save
your changes by entering write memory at the CLI command
prompt.
Note. You cannot include spaces between words when
entering a system name.
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 informa-
For example:
-> system name EngSwitch3
Note. If the switch reboots following a write memory
command entry, the switch will run from the
Specifying the Switch’s Location
/flash/certified directory. As a result, subsequent configu-
ration changes cannot be saved using the write memory
command until the switch is once again running from the
information on these directories.
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.
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-in features.
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 stacked configurations, be sure to refer to the OmniSwitch
6850 Series Hardware Users Guide.
For example:
-> system location "NMS Lab--NE Rack"

Files and Directories
Boot and Image Files
boot.cfg File
The boot.cfg file stores your network configuration parame-
ters. When you first boot the switch, no boot.cfg file is
present. This file is automatically generated when you first
issue a write memory command to save your configuration
changes. The file is then automatically placed in the
/flash/working directory.
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.
Important. Your switch must be running from the
/flash/working directory in order to save changes to the
ries” on page 22 for more information.
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.
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.
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 new boot.params file will be automatically gener-
ated on the next system boot. However, all user-configured
information, such as IP address, gateway, and mask informa-
tion, will be lost. Therefore, it is recommended that you keep a
backup copy of this file at all times.
If all copies of this file are deleted and a system boot occurs,
your network configuration will be lost. Therefore, it is recom-
mended that you keep a backup copy of this file at all times.

Image Files
For a complete list of OmniSwitch 6850 Series image files,
along with their functions, refer to the following table:
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.
K2os.img
Contains the OmniSwitch 6850
Series operating system software.
Kbase.img
Contains base code for the switch.
Krelease.img
Contains release number information
for the system software package.
Although these files may be backed up to the root flash direc-
tory or any user-defined subdirectory, they must be present in
the /flash/working and /flash/certified directories for the
switch to operate and pass traffic.
Keni.img
Provides support for 10/100/1000
and Gigabit Ethernet.
Kadvrout.img
Ksecu.img
Alcatel-Lucent’s Advanced Routing
software package. Optional.
If you delete all copies of an image file, you will be required to
contact Alcatel-Lucent Customer Support for replacements.
Therefore, it is recommended that you keep backup copies on
your computer’s hard drive or a locally-accessible server.

Working Directory
Working and Certified
Directories
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.
OmniSwitch 6850 Series switches offer flash memory with
8 MB base ROM space and 64 MB extended ROM. This mem-
ory is used to store files, including boot and image files, that
are used for switch operations.
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.
The /flash directory contains two subdirectories: /working and
/certified. These directories work together to provide the
image rollback resiliency feature. Image rollback allows the
switch to return to a prior “last known good” version of soft-
ware in the event of a system software problem.
Saving changes: You can save config-
uration 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 the boot.cfg file in the
/flash/working directory.
Once the /flash/working directory’s configuration and image
files are road-tested and considered valid and reliable for your
network, they can be copied to the /flash/certified directory.

Certified Directory
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 the boot.cfg file. However, subsequent boots may result in
your switch running from the /flash/certified directory. There-
fore, verifying the current running directory is a key step any
time you are configuring or monitoring the switch.
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.
View the switch’s current running directory by entering the

The software in the /flash/certified directory should be treated
as the “gold master” for the switch. When you place configu-
ration and image files in this directory, you are “certifying”
them as tested and reliable. If the switch is running from the

it will “roll back” to the last known good software in the
/flash/certified directory on the next reboot.
