Stand-Alone and Stacked Configurations

Stand-Alone

A stand-alone OmniSwitch 6850 Series switch is ideal for
small and medium-sized network edge applications, offering
24 ports (OS6850-24, OS6850-24X, OS6850-P24,
OS6850-P24X, OS6850-24L, OS6850-P24L, OS6850-U24X)
and 48 ports (OS6850-48, OS6850-48X, OS6850-P48,
OS6850-P48X, OS6850-48L, OS6850-P48L) switches.

These switches provide support for enterprise-based devices,
such as computer workstations or IP telephones.

A single OmniSwitch 6850 Series switch also supports 10­Gigabit Ethernet uplinks for high-bandwidth connections to a
backbone or server.

the stack. This provides a virtual chassis with a 10/100/1000
capacity of up to 384 ports.

Note. Switches should be added one at a time in a stack.

Stacked Configurations

In addition to working as individual, stand-alone switches,
OmniSwitch 6850 Series switches can also be linked together
to form a single, high-density virtual chassis known as a stack.

Note. You cannot mix OS6800 and OS6850 switches in a
stack.

Stacking switches provides scalability by allowing users to
quickly and easily expand 10/100/1000 port density. Twenty­four 10/100/1000 ports are added for each OS6850-24,
OS6850-24X, OS6850-P24, OS6850-P24X, and
OS6850-U24X switch brought into the stack; forty-eight
10/100/1000 ports are added for each OS6850-48,
OS6850-48X, OS6850-P48, OS6850-P48X, and switch.

Twenty-four 10/100 ports are added for each OS6850-24L and
OS6850-P24L switch brought into the stack; forty-eight
10/100 ports are added for each OS6850-48L and
OS6850-P48L switch.

Up to eight switches can be stacked. OmniSwitch 6850 Series
switches can be mixed and matched in any combination within

As with the stand-alone configuration, a stacked virtual chas­sis configuration provides Gigabit Ethernet uplinks and 10­Gigabit Ethernet uplinks to a backbone or server.

Network Applications

The OmniSwitch 6850 Series offers effective availability,
resiliency, and security features and are ideal for the follow­ing network applications:

• Enterprise workgroups/LAN wiring closets

• Edge deployments and branch offices

• L3 aggregation/distribution layer switches in three-tier

networks

• Small enterprise core switching

• Quality of Service (QoS) for mission critical applica-

tions

• Data center server clusters

Availability Features

Chassis Types

The switch provides a broad variety of availability features.
Availability features are hardware- and software-based safe­guards that help to prevent the loss of data flow in the unlikely
event of a subsystem failure. In addition, some availability
features allow users to maintain or replace hardware compo­nents without powering off the switch or interrupting switch
operations. Combined, these features provide added resiliency
and help to ensure that the switch or virtual chassis is consis­tently available for day-to-day network operations.

Some key availability features include:

• Management Module Redundancy

• Software Rollback

• Backup Power Supplies

• Hot Swapping

• Hardware Monitoring

For information on these availability features, refer to the
OmniSwitch 6850 Series Hardware Users Guide.

Power Supplies

OmniSwitch 6850 Series switches support power supply
components. The components include:

• PS-120W-DC backup power supply module

• PS-126W-AC backup power supply module

• PS-360W-AC backup power supply module

• PS-510W-AC backup power supply module

• Backup power supply connector cable

When backup power supply components are installed, the
primary (factory-installed) power supply continues to take on
the full power load for switch operations. Meanwhile, the
backup power supply operates in active standby mode. If the
primary power supply fails unexpectedly, the backup power
supply automatically takes up the full power load without
disrupting the switch.

.

The OmniSwitch 6850 Series backup power supply system is
chassis-based with each chassis supporting up to eight backup
power supplies. This provides 1:1 redundancy for stacks of up
to eight switches

Installing the Switch on a Tabletop or Bench

OmniSwitch 6850 Series switches can be installed freestand­ing as tabletop units. Place your switch on a stable, flat, and
static-free surface.

Note. OmniSwitch 6850 Series switches must be placed
“right side up.” Never attempt to operate a switch posi­tioned on its side.

Tabletop Mounting Steps

To install the switch as a tabletop unit, follow the steps below:

1 Position the chassis on the table or bench where it is to

be installed.

2 Be sure that adequate clearance has been provided for

chassis airflow and access to the front, back, and sides of
the switch. For recommended clearances, refer to page 16.
Also, be sure that you have placed the chassis within reach
of all required AC power sources.

Note. If you are installing a single (i.e., stand-alone)

switch, continue to “Connections and Cabling” on page 24

for additional setup procedures.

If you are placing multiple switches in a stacked configu­ration, carefully stack the remaining switches, one on top
of the other. Up to eight switches may be stacked to form
a single virtual chassis. Be sure to maintain adequate
clearance at the front, rear, left, and right side of all
switches (see page 16). Also, be sure that you have placed
all switches in the stack within reach of required AC
power sources.

October 2006 Setting Up the Hardware 17

Rack-Mounting the Switch

Refer to the important guidelines below before installing the
OmniSwitch chassis in a rack.

• Review page 16 for important chassis airflow and

access recommendations before installing.

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).

• Alcatel 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.

Note. If you are installing the switch in a 23-inch wide
rack, Alcatel offers optional 23-inch rack-mounting hard­ware. For more information, contact your Alcatel repre­sentative.

• Alcatel does not provide rack-mount screws. Use the

screws supplied by the rack vendor.

• To prevent a rack from becoming top heavy, it is

recommended that you install heavier equipment at the
bottom of the rack whenever possible.

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.

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.

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.

• If you are installing the switch in a relay rack, be sure

to install and secure the rack as per the rack manufac­turer’s specifications.

Attaching a Rack-Mount Flange

18 Setting Up the Hardware October 2006

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.

5 Align the holes in the flanges with the rack holes that

were marked in step 3.

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

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.

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.

Note. Be sure to install the screws in the bottom hole of
each flange, as shown, before proceeding.

October 2006 Setting Up the Hardware 19

Installing Combo Port SFPs

OmniSwitch 6850 Series switches offer Gigabit Ethernet
combo ports, located on the front panel (see page 64). These
combo ports support hot-swappable fiber Small Form-Factor
Pluggables (SFPs). For instructions on installing and remov­ing combo port SFPs, refer to the instruction card provided
with the SFP product.

Note. Combo port preferences are user-configurable via
the system software. Refer to the “Configuring Ethernet
Ports” in the OmniSwitch 6800/6850/9000 Network
Configuration Guide for complete details.

Note. For further details regarding supported SFP and
XFP transceivers, refer to the OmniSwitch 6850 Series
Hardware Users Guide.

For detailed information on installing backup power supply
components—including the backup power supply, connector
cables, and power cords—refer to the OmniSwitch 6850 Series

Hardware Users Guide.

20 Setting Up the Hardware October 2006

Completing a Stacked Configuration

Cabling Stacked Configurations

In order to connect stacked switches into a virtual chassis, all
modules in the stack must be connected via stacking cables
(provided).

Redundant Stacking Cable Connections

In addition to the stacking cables installed between adjacent
switch, the top-most switch and bottom-most switch in the
stack must be connected using a redundant stacking cable.
Refer to the OmniSwitch 6850 Series Hardware Users Guide
for more information on the redundant stacking cable connec­tion.

Supported Cabling Patterns

Each switch provides two stacking ports: stacking port A and
stacking port B. Cables can be connected in any pattern. In
other words, the cable connected to stacking port A of one
switch can be connected to either stacking port A or stacking
port B of the adjacent switch. However, it is strongly recom­mended that the cabling pattern remains consistent across the
stack. For a cabling diagram and additional information on
cabling the stack, refer to the OmniSwitch 6850 Series Hard­ware Users Guide.

Cabling Steps

1 Before inserting a stacking cable into one of the stack-

ing ports, be sure to orient the stacking cable connector

properly. The wide portion of the connector must be

facing up. Refer to the diagram below for more informa-

tion.

Connector Top

End View of Stacking Cable Connector

2 Starting from the top of the stack, insert one end of the

stacking cable into either stacking port A or stacking port

B. The stacking port (A or B) depends on your preferred

cabling pattern. Refer to the OmniSwitch 6850 Series

Hardware Users Guide for detailed information on cabling

patterns. Be sure that cable connector is completely

inserted and fully seated in the chassis.

3 Insert the other end of the stacking cable into the stack-

ing port of the switch immediately below. Once again, the

stacking port (A or B) depends on the preferred cabling

pattern.

When orienting the stacking cable connec­tor, be sure that the wider portion of the
connector is facing up, as shown. Other­wise, the stacking cable will not fit properly
in the chassis’ stacking port.

October 2006 Completing a Stacked Configuration 21

4 Repeat this procedure until all switches in the stack are

connected (see illustrations a, b, and c below).

Reminder. The diagram below shows one supported
stacking cable pattern. For additional supported cabling
patterns, refer to the OmniSwitch 6850 Series Hardware
Users Guide.

5 To provide added resiliency and redundancy, you must

install the redundant stacking cable to connect the top

switch in the stack to the bottom switch. Connect the

redundant cable now. Refer to the diagram below for more

information

next step is to connect all required network and manage­ment cables. Refer to “Connections and Cabling” on

page 24 for more information.

October 2006 Completing a Stacked Configuration 23

Connections and Cabling

Once your switch is properly set up and all the required hard­ware components are installed, you should connect all network
and management cables required for your network applica­tions. Connections may include:

• RJ-45 cable connection to the console port

• Single mode or multimode fiber cables to combo port

SFPs as required by your network

• Ethernet cables to 10/100/1000 or 10/100 Ethernet

ports as required by your network

Connecting the Serial Cable

The console port, located on the chassis front panel, provides a

Booting OmniSwitch 6850 Series Switches

Booting a Stand-alone Switch

The OmniSwitch 6850 Series switch does not use an on/off
switch. The power cord is the switch’s only connect/discon­nect device. The power connector socket is located on the
switch’s rear panel. For more information, refer to

“OmniSwitch 6850 Series Rear Panel” on page 72.

To boot the switch, plug the power cord (provided) into the
power connector socket at the switch’s rear panel. Next, plug
the power cord into an easily-accessible power source, such as
a grounded AC outlet or an Uninterruptible Power Supply
(UPS).

The switch immediately begins the boot process. Allow a few
moments for the switch to boot completely, then verify the
status of all LEDs on the switch’s front panel. A successful
boot for a stand-alone switch displays the following LED
states:

The stack immediately begins the boot process. Allow a few
moments for all elements in the stack to boot completely, then
verify the status of all LEDs on the switch’s front panel.

A successful boot for a stacked configuration displays the
following LED states.

Booting Stacked Configurations

Once the switches have been connected into a virtual chassis
and the network cables have been attached, the next step is to
manually power on the stack. The OmniSwitch 6850 Series
switch does not use an on/off switch. The power cord is the
switch’s only connect/disconnect device. The power connec­tor socket is located on the switch’s rear panel. For more infor­mation, refer to “OmniSwitch 6850 Series Rear Panel” on

page 72.

To boot the stack, plug the power cord (provided) into the
power connector socket at the rear panel of each switch in the
stack. Next, plug all power cords, in rapid succession, into
easily-accessible power sources, such as grounded AC outlets
or an Uninterruptible Power Supply (UPS).

When a stack of OmniSwitch 6850 Series switches boots, the
system software automatically detects the switch in the stack
with the lowest MAC address. This switch is assigned the
primary management role and, by default, is given the slot
number 1. The module connected to the primary’s stacking
port A is automatically assigned the secondary management
role and given the slot number 2.

As the other modules in the stack become operational, they are
assigned idle roles and are automatically assigned unique slot
numbers (3–8, depending on the number of switches in the
stack). The slot numbering for idle modules is determined by
each module’s physical location in the stack.

Note. As the slot numbers are dynamically assigned,

boot.slot.cfg files are auto-generated in the /flash direc-

tory of each switch. When the stack is subsequently

booted, each switch reads its slot number assignment from

this file and comes up accordingly.

In the example below, the fourth switch from the top is elected
the primary management module for the stack. (It can be
assumed that this switch has the lowest MAC address in the
stack.) This switch is automatically assigned slot number 1.

Dynamic Slot Numbering and

October 2006 Booting OmniSwitch 6850 Series Switches 27

Manual Slot Numbering and Manage­ment Role Assignment

Slot numbers for a stack, as well as primary and secondary
management roles, can be manually assigned.

Slot 6 - Idle

Slot 7 - Idle

Slot 8 - Idle

Slot 1 - Primary

Slot 2 - Secondary

Slot 3 - Idle

Slot 4 - Idle

Slot 5 - Idle

The switch immediately below is connected to the primary
switch’s stacking port A and, as a result, is assigned the
secondary management role and given slot number 2.

The system software allows the switch immediately below slot
2 to have the next slot number preference. It is assigned an idle
role and given the slot number 3. The switch immediately
below slot 3 is given the slot number 4, and so on. When the
bottom of the stack is reached, the slot numbering sequence
resumes at the top of the stack, as shown. This helps ensure a
more ordered and manageable stack topology.

By controlling the stack’s slot numbering and management
module assignments, users can create a customized stack
topology. For example, the primary management module
(slot 1) can be assigned to the top-most switch in the stack; the
secondary management module (slot 2) can be assigned to the
switch immediately below, an so on.

Refer to “Assigning Slot Numbers for a Stack” on page 35 for
steps for manually assigning slot numbers.

28 Booting OmniSwitch 6850 Series Switches October 2006

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.
Complete the following steps during your first login session:

• Log in to the switch or stack

• Unlock session types

• Change the login password

• Set the date and time

• Set optional system information

• Save your changes

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.

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:

• Login (i.e., user name)—admin

• Password—switch

To log in to the switch or stack, enter admin at the login
prompt:

login: admin

Next, enter the factory default password, switch, at the pass­word prompt:

password: switch

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.

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/
6850/9000 Switch Management Guide.

Assigning an IP address to your OmniSwitch 6850 Series
switch is an important step in the setup process.

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.

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

exactly as shown, followed by the IP address. For example:

-> ip interface vlan_1 address 172.2.120.1
vlan 1

30 Your First Login Session October 2006

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.

The CLI command used to unlock session types is

aaa authentication.

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 pass­word 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.

Unlocking All Session Types

To unlock all session types, enter the following command
syntax at the CLI prompt:

-> aaa authentication default local

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

To unlock WebView (HTTP) sessions only, enter the follow­ing command:

-> aaa authentication http local

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 succes­sion. For example:

-> aaa authentication http local

-> aaa authentication telnet local

-> aaa authentication ftp local

How many sessions are allowed?

Once a session type has been unlocked, the following number
of sessions is allowed for each type:

Telnet sessions allowed 4 concurrent sessions

FTP sessions allowed 4 concurrent sessions

HTTP (Web browser) ses-

4 concurrent sessions

sions allowed

Total sessions (Telnet, FTP,

13 concurrent sessions

HTTP, console)

SNMP sessions allowed 50 concurrent sessions

Changing the Login Password

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

All subsequent login sessions—including those through the
console port—will require the new password in order to access
the switch.

1 Be sure that you have logged into the switch as user

type admin (see “Logging in to the Switch” on page 29).

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 non­repeating 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 informa­tion. Also note that new password information is retained
following a reboot.

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.

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—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.

-> system timezone pst

To enable Daylight Savings Time, enter the following
command.

-> system daylight savings time enable

32 Your First Login Session October 2006

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

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.

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

-> 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.

To set the current date for the switch, enter system date,
followed by the current date in mm/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

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 [e-mail]"

" ").

Specifying a System Name

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

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

Note. You cannot include spaces between words when

entering a system name.

For example:

-> system name EngSwitch3

October 2006 Your First Login Session 33

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 "NMS Lab--NE Rack"

" ").

Viewing and Saving Changes

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

Note. If the switch reboots following a write memory

command entry, the switch will run from the

/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

/flash/working directory. See page 47 for important infor-

mation 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-in features.

For stacked configurations, be sure to refer to “Assigning Slot

Numbers for a Stack” on page 35

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 the boot.cfg file, refer to page 45.

34 Your First Login Session October 2006

Assigning Slot Numbers for a Stack

It may be desirable to manually assign slot numbers within a
stacked configuration in order to create a sequential number­ing scheme from the top of the stack to the bottom (or vice­versa). For example, the preferred physical location of the
primary management module may be either the top or the
bottom of the chassis. This can be achieved by manually
assigning slot numbers.

To manually assign slot numbers to one or more modules in a
stack, use the stack set slot command. This command writes
slot information to the boot.slot.cfg file located in a switch’s

/flash directory. It is this saved slot information that the

switch will assume following a reboot.

This example shows a stack in which the primary and second­ary switches are physically positioned in the middle of the
stack. Although the stack will operate normally with this
primary and secondary module positioning, it may be prefera­ble for management purposes to have the primary and second­ary switches at either the top or the bottom of the stack. For
this example, the primary and secondary roles will be assigned
to the top of the stack. To reassign the slot numbers, follow the
steps below:

Slot 6 - Idle

Slot 7 - Idle

Slot 8 - Idle

Slot 1 - Primary

Slot 2 - Secondary

Slot 3 - Idle

Slot 4 - Idle

Slot 5 - Idle

October 2006 Assigning Slot Numbers for a Stack 35

1 Use the stack set slot command to reassign slot

numbers, starting from the top of the stack. For example:

-> stack set slot 6 saved-slot 1

-> stack set slot 7 saved-slot 2

-> stack set slot 8 saved-slot 3

-> stack set slot 1 saved-slot 4

-> stack set slot 2 saved-slot 5

-> stack set slot 3 saved-slot 6

-> stack set slot 4 saved-slot 7

-> stack set slot 5 saved-slot 8

Slot 1 - Primary

Slot 2 - Secondary

Slot 3 - Idle

Slot 4 - Idle

Slot 5 - Idle

2 Use the reload all command to reload all modules in

the stack. For example:

-> reload all

Because slot 6 is the top-most switch in the stack, it is reas­signed the slot 1 (i.e., primary) position; because slot 7 is
located immediately below slot 6, it is reassigned the slot 2
(i.e., secondary) position, etc.

When the stack comes up following the reboot, the manually­configured slot numbers display as follows:

Slot 6 - Idle

Slot 7 - Idle

Slot 8 - Idle

The initial setup for your stacked configuration of OmniSwitch
6850 Series switches is now complete. Refer to the following
sections for additional information on your OmniSwitch
product.

36 Assigning Slot Numbers for a Stack October 2006

CLI Basics

The Command Line Interface (CLI) allows you to configure
and monitor your switch by entering single-line commands.
The CLI can be accessed through terminal or Telnet sessions.

Note. Configuring the switch using the CLI is also
referred to as “online configuration.”

The following section provides basic information on CLI
assistance features. For detailed information on the CLI,
including syntax conventions, usage rules, command docu­mentation, and a quick reference card, refer to the OmniSwitch

CLI Reference Guide and the “Using the CLI” chapter in the
OmniSwitch 6800/6850/9000 Switch Management Guide.

CLI Assistance Features

The CLI provides built-in features that assist you while enter­ing commands. These features include:

• Syntax checking

• Command line help

• Partial keyword completion

• Deleting and inserting characters

• Previous command recall

• Prefix recognition

• Prefix prompt

• Command history

Note. The software supports vt100 terminal emulation;

CLI assistance features may be limited if your terminal

emulation software is using a setting other than vt100.

Syntax Checking

If you make a mistake while entering command syntax, the
CLI provides clues about how to correct the error. Whenever a
command error is entered, two indicators are displayed:

• An error message describing the type of error.

• A carat (^) character indicating where the error

occurred.

For example, the syntax

-> show vlan router port mac status

results in the following error:

-> show vlan router port mac status
^
ERROR: Invalid entry: "port"

Because port is not a valid syntax for the command, the error
message shows it as an invalid entry and the carat indicates
where the problem has occurred. For this example, the valid
command syntax is

-> show vlan router mac status

October 2006 CLI Basics 37

Command Line (?) Help

Partial Keyword Completion

The CLI provides additional help in the form of the question
mark (?) character. The ? character provides information that
helps you build your command syntax. For example, if you
enter

-> show vlan router

at the command line and are unsure of the next keyword, you
can enter the ? character for additional options (be sure to
include a space between the last keyword and the ? character):

-> show vlan router ?
^

MAC IP
(Vlan Manager Command Set)

The carat character (^) indicates the point where you invoked
the command line help. Possible keyword options, along with
the corresponding command set, are displayed. Here, you can
continue building the command by entering either mac or ip.

Some command completion options may indicate user-defined
information. For example: <string>, <slot/port>,
<hh:mm:ss>, etc. The option <cr> indicates that the
command can be completed by pressing Enter.

The CLI has a partial keyword recognition feature. Instead of
typing the entire keyword, you can type only the minimum
number of characters needed to uniquely identify the keyword,
then press the Tab key. The CLI will complete the keyword
and place the cursor at the end of the command line.

If you do not enter enough characters to uniquely identify the
keyword, pressing the Tab key will have no effect.

If you enter characters that do not belong to an applicable
keyword, pressing the Tab key will remove the characters and
place the cursor back to its previous position.

Deleting Characters

You can delete CLI command characters by using the Back­space key or the Delete key. The Backspace key deletes each

character in the line, one at a time, from right to left.

To change incorrect syntax with the Delete key, use the Left
Arrow key to move the cursor to the left of the character to be
deleted, then use the Delete key to remove characters to the
right of the cursor.

Note. The ? character can be entered at any time. In addi­tion, you can type the ? character alone at the CLI prompt
to display root keywords for all command sets.

38 CLI Basics October 2006

Inserting Characters

Prefix Recognition

To insert a character between characters that are already typed,
use the Left and Right Arrow keys to place the cursor into
position, then type the new character. Once the syntax is
correct, execute the command by pressing Enter. In the
following example, the user enters the wrong syntax to execute
a command. The result is an error message.

-> show micrcode
^
ERROR: Invalid entry: "micrcode"

To correct the syntax without retyping the entire command
line, use the !! command to recall the previous syntax. Then,
use the Left Arrow key to position the cursor between the “r”
and the “c” characters. To insert the missing character for this
example, type “o” as shown:

-> !!

-> show microcode

Previous Command Recall

To recall the last command executed by the switch, press the
Up Arrow key at the prompt and the previous command will
display on your screen. You can execute the command again
by pressing Enter, or you can edit it first by deleting or insert­ing characters.

Prefix recognition is a CLI feature that reduces redundant
command line entry by storing commonly-used prefix infor­mation for certain commands. The CLI assumes this stored
prefix information when the next command is entered. For
example, if you enter

-> vlan 32

at the command line, the CLI will store the vlan 32 prefix
information. If you want to create enable classification of
tagged packets received on mobile ports enter

-> mobile-tag enable

instead of the full command:

-> vlan 32 mobile-tag enable

October 2006 CLI Basics 39

The following command families support prefix recognition:

Prefix Prompt

• AAA

• Interface

• Link Aggregation

• Quality of Service (QoS)

• Spanning Tree

• VLAN Management

You can set the CLI to display the current command prefix as
the command prompt by entering the following command:

-> prompt prefix

After entering this command, your command prompt will
include current stored prefix information until a new prompt is
specified. For example, the following is a prompt for a user
who has begun configuring VLAN 32:

-> vlan 32

To set the prompt back to the default arrow ( -> ), enter the
following syntax, exactly as shown, at the prefix prompt:

-> prompt string

Command History

You can view a list of up to 30 of the most recently executed
commands via the show history command. For example:

-> show history
1 aaa authentication default local
2 password
3 system timezone pst
4 system daylight savings time enable
5 system time 14:58:00
6 system date 11/06/2002
7 system contact "JSmith [e-mail]"
8 system name EngSwitch3
9 system location "NMS Lab--NE Rack"
10 show system
11 modify boot parameters
12 show history

40 CLI Basics October 2006

Note that the most recent commands are displayed lower in the
list. For this reason, the show history command will always be
listed last.

You can recall commands from the history list by entering an
exclamation point ( ! ). For example:

-> !4

-> show temperature

Command Logging

OmniSwitch 6850 Series switches provide command logging.
This feature allows users to record up to 100 of the most recent
commands entered via Telnet and console sessions. In addi­tion to a list of commands entered, the results of each
command entry are recorded. Results include information such
as whether a command was executed successfully, or whether
a syntax or configuration error occurred.

The CLI prints the fourth command from the history list (in
this case, show temperature) at the CLI prompt.

You can also recall the last command in the history list by
entering two exclamation points ( !! ). For example:

-> !!

-> show history

To specify the number of commands displayed in the history
list (1 - 30), use the history size command. For example:

-> history size 10

To view the current history list settings, use the show history
parameters command. For example:

-> show history parameters
History size: 30
CurrentSize: 10
Index Range: 1-10

Note. The command history feature differs from the

command logging feature in that command history buff-

ers up to 30 of the most recent commands. The command

information is not written to a separate log file. Also, the

command history feature includes only general keyword

syntax (i.e., it does not record full syntax, date and time,

session IP address, and entry results). For more informa-

tion on command history, refer to page 40.

Refer to the sections below for more information on configur­ing and using CLI command logging. For detailed information
related to command logging commands, refer to the
OmniSwitch CLI Reference Guide.

Enabling Command Logging

By default, command logging is disabled. To enable command
logging on the switch, enter the following command:

-> command-log enable

October 2006 CLI Basics 41

When command logging is enabled via the command-log
enable syntax, a file called command.log is automatically

created in the switch’s /flash directory. Once enabled, configu­ration commands entered on the command line will be
recorded to this file until command logging is disabled.

The command.log file has a 66402-byte capacity. This capac­ity allows up to 100 of the most recent commands to be
recorded. Because all CLI command logging information is
archived to the command.log file, command history informa­tion will be lost if the file is deleted.

Note. The command.log file cannot be deleted while the
command logging feature is enabled. Before attempting to
remove the file, be sure to disable command logging.

For detailed information on command logging, refer to the
OmniSwitch 6800/6850/9000 Switch Management Guide.

Common CLI Commands

The following table lists some basic CLI commands that will
help you get acquainted with the CLI interface. Enter each

Offline Configuring

You can configure OmniSwitch 6850 Series switches using an
ASCII-based text file. This is referred to as offline configur-
ing. With offline configuring, CLI commands may be typed
into a text document (referred to as a text-based configuration
file) and then uploaded and applied to the switch.

An ASCII-based configuration file can be viewed or edited at
any time using a standard text editor (e.g., WordPad). The
switch also offers its own text editing buffer, so a file can be
edited in the flash file directory without having to be down­loaded to a workstation.

Because they are portable, stand-alone documents, configura­tion files allow users to easily clone switch configurations.
Moreover, the ability to store a broad range of network infor­mation in a single text file facilitates troubleshooting, testing,
and overall network readability.

Syntax Checking

Offline configuration includes a syntax check feature. This
function will report syntax errors or typos that might cause a
command to be rejected by the switch when a configuration
file is applied.

October 2006 CLI Basics 43

Scheduling a Configuration File to be Applied at a Later Time

You can apply a file to the switch immediately. You can also
schedule a file to be applied either at a specific date and time,
or after a specific amount of time has passed. Timer sessions
can greatly facilitate maintenance tasks, such as synchronized
batch updates.

Generating Snapshots of the Current Configuration

A generated snapshot captures the switch’s current configura­tion settings in a single text file. Captured configuration
settings can then be viewed or edited offline at any time. Trou­bleshooting is greatly facilitated, as aggregate network infor­mation can be read at a glance.

Snapshot files can be used as configuration files for a single
switch or for multiple switches. This allows easy cloning of
switch configurations for networks requiring multiple, simi­larly-configured switches. Simply place the snapshot file in the
appropriate directory of the switch(es) you want to configure
and use the CLI to apply the file.

For detailed information on offline configuring and the
features described above, refer to the OmniSwitch 6800/6850/
9000 Switch Management 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 new boot.params file will be automatically gener­ated on the next system boot. However, all user-configured
information, 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, 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.

Important. Your switch must be running from the

/flash/working directory in order to save changes to the

boot.cfg file. Refer to “Working and Certified Directo-

ries” on page 47 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.

October 2006 Files and Directories 45

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-defined subdirectory, 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 Customer Support for replacements. There­fore, it is recommended that you keep backup copies on your
computer’s hard drive or a locally-accessible server.

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

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.

Keni.img Provides support for 10/100/1000

and Gigabit Ethernet.

Kadvrout.img Alcatel’s Advanced Routing soft-

ware package. Optional.

Ksecu.img Provides enhanced security features

for the switch, such as Authenticated
VLANs (AVLANs).

K2diag.img Provides enhanced hardware diag-

nostics for the switch.

46 Files and Directories October 2006

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 the
image 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 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.

October 2006 Files and Directories 47

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 the boot.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:

-> show running-directory

CONFIGURATION STATUS

Running CMM : PRIMARY,
CMM Mode : DUAL CMMs,
Current CMM Slot : 1,
Running configuration : WORKING,
Certify/Restore Status : CERTIFY NEEDED

SYNCHRONIZATION STATUS

Flash Between CMMs : SYNCHRONIZED,
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 the show running-directory
command output, refer to the “CMM Commands” chapter in
the OmniSwitch CLI Reference Guide.

48 Files and Directories October 2006

Can I save changes to the Certified directory?

Working and Certified Are Identical

No. The /flash/certified directory is intended to store only
tested, reliable configuration and image files. Configuration
changes must be saved to the boot.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.

If the software in the /flash/working and /flash/certified
directories 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/working directory.

Working and Certified
contents are identical.

Loading Software

The following section describes the procedure for loading new
release software to your switch. Note that the procedure varies
slightly for stand-alone and stacked OmniSwitch 6850 Series
configurations. Follow the steps that apply to your system.

Note. For more detailed information on loading software
and working with directories in both stand-alone and
stacked configurations, refer to the “Managing CMM
Directory Content” chapter in the OmniSwitch 6800/6850/
9000 Switch Management Guide.

Stand-Alone Configurations

1 Verify that all required image files from the new soft-

ware release are located on your computer’s hard drive or
a locally-accessible server.

2 Establish an FTP session to the switch, then access the

/flash/working directory.

Note. Before attempting to establish an FTP session, be

sure that you have first unlocked the FTP session type via
the aaa authentication command. Otherwise, an FTP
login error will occur. See “Unlocking Session Types” on

page 31 for more information.

3 Using your FTP client or the CLI’s rm command,

delete all .img files from the /flash/working directory.

You can use the asterisk (*) wildcard to delete all .img

files at once. For example:

-> rm working/*.img

Important. Do not delete the boot.cfg file. Otherwise,

any configuration changes you have saved will be lost.

Also, do not delete files from the /flash/certified direc-

tory.

4 Using your FTP client, upload all required .img files

from the new software release to the /flash/working direc-

tory.

5 Use the install command after the software files have

been transferred to the switch via FTP. For example:

-> install /flash/working/*.img

Note. For more information on the install command, refer
to the OmniSwitch 6800/6850/9000 Switch Management
Guide or the CLI Reference Guide.

6 Reload the switch from the /flash/working directory.

To do this, enter

-> reload working no rollback-timeout

at the CLI prompt.

Note. This reload process will take a few moments to
complete.

Following the reload, the switch will come up running from
the /flash/working directory (i.e., the new release software)
until the next system reboot. Meanwhile, the software in the
/flash/certified directory remains unchanged and available as
a last known good version if an error should occur with the
new software.

Once the release software is considered valid and reliable with
your network configuration, the contents of the

/flash/working directory can be copied to the
/flash/certified directory via the copy working certified

command.

52 Loading Software October 2006

Using WebView

The switch can be configured and monitored using WebView,
Alcatel’s Web-based device management tool. WebView soft­ware is pre-installed in the switch; you are not required to load
additional software.

OmniSwitch 6850 Series LEDs

Slot Indicator LED

The slot indicator LED displays the
switch’s current slot number in a stacked
configuration (i.e., 1 – 8). Displays 0
when the switch is booting. Blinks 1–8 if

the switch is in pass-through mod

e.

OK. Solid green when the switch has passed
hardware diagnostic tests and the system soft­ware is operational. Solid amber when a hard­ware or system software failure occurs. Blinks
amber when the software is in a transitional
state (e.g., when software is being downloaded
to the switch).

PRI. Solid green when the switch is either a
stand-alone switch or the primary switch in a
stack; solid amber if the switch status is sec­ondary; off if the switch is idle (i.e., neither
primary or secondary).

PWR. Solid green when the primary
(i.e., factory-installed) power supply
status is OK and the power supply is
operating normally. Solid amber in the
event of a power supply failure.

BPS. Solid green when an optional
redundant power supply is installed
and operational. Solid amber if a
redundant power supply failure
occurs; off when no redundant power
supply is installed.

System Status LEDs

Combo Port LEDs

Displays solid green when an SFP is installed in the corresponding port and a link state exists; blinks
green when transmitting or receiving traffic; off when no activity is present or no SFP is installed.
