Availability Features OmniSwitch 6850E Series
Availability Features
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.
Hardware-related availability features include:
•
•
•
•
Software Rollback
Software rollback (also referred to as image rollback) essentially allows the OmniSwitch to return to a prior “last known good” version of software in the event of a system software problem. The switch controls software rollback through its resilient directory structure design (i.e., /flash/working and /flash/ certified).
For detailed information on the software rollback feature, as well as the switch’s /flash/working and
/flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the OmniSwitch
AOS Release 6 Series Switch Management Guide.
Backup Power Supplies
The switches support an optional backup power supply. This power supply is connected to the rear of the unit and provides redundant chassis power on a 1:1 basis. There is a power shelf provided with the unit that slides into the rear of the chassis and is used to hold the power supplies.
Backup power supplies operate 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.

January 2013
OmniSwitch 6850E Series Availability Features
Hot Swapping
Hot swapping refers to the action of adding, removing, or replacing components without powering off switches or disrupting other components.This feature facilitates hardware upgrades and maintenance and allows users to easily replace components in the unlikely event of hardware failure.
The following hardware components can be hot swapped:
•
Backup power supply
•
Backup power supply connector cables
•
Transceivers
For instructions on hot swapping backup power supplies, refer to Chapter 2, “OmniSwitch 6850E Series
Chassis and Hardware Components.”
.
Note: The OmniSwitch 6850E chassis fans are not hot swappable or field replaceable. If there is a failure of any of the fans the entire chassis must be replaced. Please contact Service & Support for chassis replacement instructions. Replacement time is typically 5 days with expedited service available.
Hardware Monitoring
Automatic Monitoring
Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. If an error is detected (e.g., over-threshold temperature), the switch immediately sends a trap to the user. The trap is displayed on the console in the form of a text error message. (In the case of an over-threshold temperature condition, the chassis displays an amber TMP LED in addition to sending a trap.)
LEDs
LEDs, which provide visual status information, are provided on the chassis front panel. LEDs are used to indicate conditions such as hardware and software status, temperature errors, link integrity, data flow, etc.
For detailed LED descriptions, refer to Chapter 2, “OmniSwitch 6850E Series Chassis and Hardware
User-Driven Monitoring
User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access the current status of hardware components. The user enters “show” commands that output information to the console. Monitoring information for chassis components, such as the optional back up power supply, chassis temperature sensor, and chassis fans is provided in
Chapter 2, “OmniSwitch 6850E Series Chassis and Hardware Components.”
The show commands for all the features are described in detail in the
OmniSwitch CLI Reference Guide.

Chassis Airflow
The fans pull air from the air intake vent located on the left-hand side of the chassis. The air is directed horizontally through the chassis and past the circuit board. Airflow is then exhausted through the fan vents at the right-hand side of the chassis. Refer to the illustrations below for more information.

Mounting the Switch OmniSwitch 6850E Series Chassis and Hardware Components
Blank Cover Panels
Blank cover panels are provided with your switch and are used to cover empty backup power supply bays and 10 Gigabit uplink bays. These cover panels play an important role in chassis airflow and temperature management. They also protect the switch’s processor board and other sensitive internal switch components from physical damage by closing off the chassis.
When blank cover panels are missing, air does not take the direct route from the air intake vent, through the chassis, and then out through the fan exhaust vents (see
page 2-33 ). Instead, a portion of the airflow is
allowed to be drawn in through the rear of the chassis. As a result, normal airflow is disrupted and an extra task is placed on the fans to cool the chassis.
If your switch is not equipped with a backup power supply connection or 10 Gigabit uplink, and blank cover panels are not installed over empty bay locations, airflow is adversely affected. Since they regulate airflow and help protect internal chassis components, blank cover panels should remain installed over empty bays at all times.

OmniSwitch 6850E Series Chassis and Hardware Components Mounting the Switch
Installation Options
The OmniSwitches can be installed in two ways:
•
Tabletop installation
•
Rack-mount installation
Installing the Switch on a Tabletop or Bench
OmniSwitches switches can be installed freestanding as tabletop units. Place your switch on a stable, flat, and static-free surface.
Note. 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
. Also, be sure that you have placed the chassis within the reach of all the required AC power sources.
3 If you are installing a single (i.e., stand-alone) switch, continue to
for additional setup procedures.
“Setting Up a Stacked Configura-
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
). Also, be sure that you have placed all switches in the stack within reach of required AC power sources. Once the
switches are stacked together, continue to
“Cabling Stacked Configurations” on page 2-38 for additional
setup procedures.
Note. Switches should be added one at a time in a stack.

Mounting the Switch OmniSwitch 6850E Series Chassis and Hardware Components
Rack-Mounting the Switch
Refer to the important guidelines below before installing the OmniSwitch chassis on a rack.
•
It is recommended that two people install the switch on the rack—one person to hold the chassis and position it on the rack, and a second person to secure the chassis to the rack using attachment screws
(not supplied).
•
Alcatel-Lucent provides two rack-mount flanges with each OmniSwitch 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-Lucent offers optional 23-inch rackmounting hardware. For more information, contact your Alcatel-Lucent representative.
•
Alcatel-Lucent 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.
•
If you are installing the switch on a relay rack, be sure to install and secure the rack per the rack manufacturer’s specifications.
•
Review
for important chassis airflow and access recommendations before installing.
Rack Mounting Steps
To rack-mount the switch, follow the steps 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.

To rack mount a stacked configuration, install all switches that are to be included in the stacked configura-
tion as described on pages 2-36
through 2-37 . Up to eight switches may be stacked to form a single virtual
chassis.
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 installation.
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
OmniSwitch 6850E Series Stacks”
for more information on the redundant stacking cable connection.
Supported Cabling Patterns
Each switch provides two stacking: 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
Chapter 6, “Managing OmniSwitch 6850E Series Stacks.”
Cabling Steps
1 Before inserting a stacking cable into one of the stacking, 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 information.
Connector Top
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.

Console Port OmniSwitch 6850E Series Chassis and Hardware Components
Console Port
The console port, located on the chassis front panel, provides a console connection to the switch and is required when logging into the switch for the first time. By default, this RJ-45 connector provides a DTE console connection.
Serial Connection Default Settings
The factory default settings for the serial connection are as follows: baud rate parity data bits (word size) stop bits flow control
8
1
9600 none none
Modifying the Serial Connection Settings
The switch’s serial connection defaults are listed above. If you wish to modify the default serial connection settings (i.e., baud rate, parity, data bits, and stop bits), refer to the following steps:
Note .
You must be connected to the switch via the console port before attempting to change serial connection settings. Otherwise, an error message will display.
For switches in a stacked configuration, all changes must be configured before the switches are cabled together. In other words, you must configure these settings when each switch is operating as a stand-alone unit.
1
Enter the modify boot parameters command at the CLI prompt. The boot prompt displays:
Boot >
2 To change the baud rate, enter boot serialbaudrate, followed by the desired baud rate value. Options include 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 76800, and 115200. For example:
Boot > boot serialbaudrate 19200
Note . Setting the console port to speeds above 9600 baud can cause problems with Zmodem uploads.
3
To change the parity value, enter boot serialparity, followed by the desired parity value. Options include none (default), even, and odd. For example:
Boot > boot serialparity even
4
To change the data bits (i.e., word size) value, enter boot serialwordsize, followed by the number of data bits. Options include 7 and 8 (default). For example:
Boot > boot serialwordsize 7 page 2-44 OmniSwitch 6850E Series Hardware Users Guide
January 2013
OmniSwitch 6850E Series Chassis and Hardware Components Console Port
5
To change the stop bits value, enter boot serialstopbits, followed by the number of stop bits. Options include 1 (default) and 2. For example:
Boot > boot serialstopbits 2
6 Verify your current changes by entering show at the boot prompt:
Boot > show
Edit buffer contents:
Serial (console) baud : 19200
Serial (console) parity : even
Serial (console) stopbits : 2
Serial (console) wordsize : 7
(additional table output not shown)
7
You can save your changes to the boot.params file by entering commit file at the boot prompt:
Boot > commit file
When the commit file command is used, changes will not be enabled until after the next switch reboot.
8
You can also save your changes in real time to the switch’s running memory by entering commit system at the boot prompt:
Boot > commit system
Caution .
There are two important things to consider when using the commit system command to save serial connection changes:
•
Output to the terminal may become illegible due to incompatible serial connection settings between the switch and the terminal emulation software.
•
If you use the commit system command only, changes will not be saved to the switch’s boot.params file and will be lost if the switch is rebooted. To save changes to the boot.params file, refer to step 7.

Dying Gasp OmniSwitch 6850E Series Chassis and Hardware Components
Dying Gasp
If the switch loses all power it will maintain power long enough to send a Dying Gasp message before completely shutting down. An SNMP trap, Syslog message and Link OAM PDUs will be generated.
Scenarios
A Dying Gasp event will be generated in the following scenarios:
•
Primary power supply failure (if only power supply present).
•
Primary power supply failure and then backup power supply failure.
•
Backup power supply failure and then primary power supply failure.
•
When a reload command is issued.
•
When a takeover command is issued.
Note. Dying gasp will not work when both primary and backup power supplies fail simultaneously.
Connect each power supply to a separate independent power source to avoid simultaneous power failures.
SNMP Trap
As soon as the power failure is detected, an SNMP trap is sent to the first three configured SNMP stations.
The trap includes the following information:
•
Slot number
•
Power supply type (primary/backup)
•
Time of the failure
Use the snmp station command and refer to the SNMP Configuration chapter for information on configuring an SNMP station.
Syslog Message
As soon as the power failure is detected, the following Syslog message is sent to the first four configured
Syslog servers, along with the time of the failure:
Dying Gasp Power Failure Event Occurred
Use the swlog output socket command to add a Syslog station. Refer to the Using Switch Logging
Configuration chapter in the Network Configuration Guide for information on configuring a Syslog server. page 2-48 OmniSwitch 6850E Series Hardware Users Guide
January 2013
OmniSwitch 6850E Series Chassis and Hardware Components Dying Gasp
Link OAM PDU
As soon as the power failure is detected an 802.3ah OAM Information PDU is sent to all ports for which link OAM is enabled and the LinkOAM port status is operational. The PDU will have the Dying Gasp bit set.
Use the
efm-oam
and
efm-oam port propagate-events
commands to enable the generation of an
802.3ah OAM Information PDU upon a dying gasp event:
-> efm-oam enable
-> efm-oam port 2/1-10 propagate-events dying-gasp enable
Link OAM PDU Priority
It may not be possible to generate PDUs on all ports enabled for link OAM. Dying gasp packets will be sent in the following order based on port priority:
1. Uplink ports
2. Combo ports
3. All other ports

Installing DC Power Source Wire Leads
These instructions describe how to connect your 3-wire DC power source to the power connector on your
DC power supply. A small flat-tip screwdriver and a wire stripper are required for this procedure.
1
Prepare the three (3) wires—12 gauge—that will plug into the power supply. First make sure they are not plugged into the DC power source. Next, use a wire stripper to carefully strip between .24 and .30 inches (6-7.5 mm) off the end of each wire, removing the outer insulation to expose the copper core.
2 Open the clamp for the ground wire slot by inserting a small flat-tip screwdriver into the top of the appropriate circular hole. Loosen the screw so that the clamp for the ground wire opens.
Loosen Screw.
+ -
Clamp inside square hole will open when screw is loosened in top circular hole.
Opening Connector for Ground Wire
3 Insert the ground wire lead into the slot. The lead you insert must match the lead attached to the DC power source.
Warning. You must plug DC wire leads into the correct holes in the DC power connector. Use the labels above the DC power connector as a guide to positive, negative, and ground connections. If the wire leads are plugged into the wrong holes, the power supply will not work properly and damage to the unit may result.
Push the wire in far enough such that it reaches the back wall of the connector, about a half inch inside.

Chassis Status LEDs OmniSwitch Backup Power Shelf/System (BPS)
Power Supply Redundancy
Power supplies installed in the same OS-BPS chassis may operate in a redundant or backup configuration by sharing the same electrical load with another power supply.
Hot Swapping
OS-BPS power supplies are hot swappable. If redundant power supplies are operating in the chassis, a power supply can be removed or replaced without adversely affecting normal operation. New power supplies may be inserted in empty power supply slots at any time.
Considerations if OS-BPS is the Only Power Source In a Stack
If the primary power supply fails on any switch connected to the OS-BPS, leaving the OS-BPS as the switch's only power source, it is recommended that the primary power supply is replaced on the switch as soon as possible.
If the primary power supply fails on any PoE-enabled switch connected to the OS-BPS and the switch must be powered down, the PoE power must first be disabled on the switch using the lanpower stop CLI command before disconnecting the DB25 connector between the OS-BPS and the switch.
Chassis Status LEDs
The chassis provides a series of status LEDs located on the front panel. These LEDs offer basic status information for hardware operation and port link and activity status.

OS-BPS Connector Priority
If the total available PoE or system power drops below the minimum budget required for the current configuration, the OS-BPS automatically powers off switches according to priority until the configuration falls within the available power budget.
If the total available PoE or system power later increases to meet the power demands of the configuration, the OS-BPS returns power to those switches based on priority.
Connector priority for all OS-BPS connectors is user configurable. This allows the user to specify which switches will remain operational in the event of a power budget shortfall.
By default, connector 1 receives the highest priority and connector 8 receives the lowest priority.
Additional default priorities are specified below.

Mounting the Chassis
General Mounting Recommendations
Elevated Operating Ambient Temperature. If installed in a closed or multi-rack assembly, the operating ambient temperature of the rack environment may be greater than the room’s ambient temperature.
Therefore, consideration should be given to the maximum rated ambient temperature (Tmra) specified on
Reduced Air Flow. Installation of the equipment in a rack should be such that the amount of air flow
Mechanical Loading. Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven loading.
Circuit Overloading. Consideration should be give to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on overcurrent protection and supply wiring.
Reliable Earthing. Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch (e.g., use of power strips).
Airflow Recommendations
To ensure proper airflow, the OS-BPS should be placed in a well-ventilated area with minimum recommended clearance at front, back and sides of the chassis. (Clearance is not required at the top and bottom of the chassis.) Restricted airflow can cause the chassis to overheat, which can lead to system failure. Refer to the following important guidelines regarding airflow:
}
Rear. 6 inches minimum at rear of chassis.
Sides. 2 inches minimum at left and right sides.
}
Front. 6 inches minimum at front of chassis.

OmniSwitch BPS Airflow
The OmniSwitch Backup Power Shelf/System (BPS) power supplies are installed in power supply bays located at the front of the chassis. Each power supply draws air through intake vents at the front of the power supply. The air is then directed straight through each power supply and out the rear chassis vent.

Blank Cover Panels
Blank cover panels are provided with your chassis and are used to cover empty slots. These cover panels play an important role in chassis airflow and temperature management. If your chassis is not fully populated and blank cover panels are not installed over empty slot locations, airflow is affected.
When blank cover panels are missing, air does not take the direct route from the power supply air intake vents, through the power supply body, and out through the chassis exhaust vent as intended. Instead, a portion of the airflow is allowed to escape through other openings in the chassis. As a result, normal airflow is disrupted and an extra task is placed on the system to cool the chassis.
Note. Because they regulate airflow and help protect internal chassis components, blank cover panels should be installed over empty power supply bays at all times.

OmniSwitch Backup Power Shelf/System (BPS) Rack-Mounting
Rack-Mounting
Refer to the following important guidelines before installing the chassis in a rack:
•
Two people are required to rack mount the chassis: One person to lift the chassis into position and one person to secure the chassis to the rack using the rack mount screws.
•
•
•
The chassis has rack-mount flanges that support standard 19-inch rack mount installations.
Alcatel-Lucent 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 the chassis at the bottom of the rack whenever possible.
•
If you are installing the chassis in a relay rack, be sure to install and secure the rack per rack manufacturer’s specifications.
Note. Never rack mount the chassis using only the front-installed rack mount flanges. Due to the chassis depth and overall weight, it must be mounted using front and rear flanges (as described below) or by attaching flanges to the mid portion of the chassis (see “Mid-Mounting the Chassis In the Rack” on page
4-10). Failure to properly mount the chassis may result in the chassis sagging in the rack or damage to the chassis and its components.
To rack mount the chassis, follow the steps below.
1 Mark the holes on the rack where the chassis is to be installed.
2
One person should lift and position the chassis until the rack-mount flanges are flush with the rack post.
3 Align the holes in the flanges with the rack holes marked in step 1.
4
Once the holes are aligned, the second person should insert a screw through the bottom hole on each flange. Tighten both screws until they are secure.

OmniSwitch Backup Power Shelf/System (BPS) Grounding the Chassis
Grounding the Chassis
The chassis has a grounding lug located on the rear of the chassis. This lug uses 10-32 screws and is surrounded by a small paint-free area, which provides metal-to-metal contact for a ground connection.
Use this connector to supplement the ground provided by the AC power cord. To do so, install a Panduit
Grounding Lug (type LCD8-10A-L) using 8AWG copper conductors to the paint-free area.
Additionally, ensure that all AC sources used to power the OS-BPS and the OmniSwitches share a common electrical ground. The “Earth Ground” for all AC sources must be a solid common ground that does not have any electrical potential (voltage) between them.

OmniSwitch BPS Operation OmniSwitch Backup Power Shelf/System (BPS)
OmniSwitch BPS Operation
The amount of power supplied by the OS-BPS depends on the number of system and/or PoE power supplies installed as noted in the table below:
1 System P/S (450W)
2 System P/S (900W)
1 PoE P/S
2 PoE P/S
3 PoE P/S
Can support up to 4 OS6850E primary power supply failures.
Can support up to 8 OS6850E primary power supply failures.
Can support up to1200W (low line) or 2000W (high line) of PoE power.
Can support up to 2400W (low line) or 4000W (high line) of PoE power.
Can support up to 3600W (low line) or 6000W (high line) of PoE power.
Single Mode (N+1)
When configured in single mode the OS-BPS power is unmanaged, meaning all the installed system power supplies act as a single redundant system power supply and all the installed PoE power supplies act a single redundant PoE power supply to provide backup power. There is no priority given to any connector, the OS-BPS will continue to provide power as long as the amount of power required by the OmniSwitches is less than the total power available on the OS-BPS. The number of OmniSwitch primary power supplies that can fail but still have redundant system power supplied by the OS-BPS depends on the number of OS-
BPS system power supplies installed. PoE coverage is dependent on PoE power usage. Multiple power failovers will only be supported for PoE if the total current draw is less than available PoE power on the
OS-BPS.
Full Mode (N+N)
When configured in full mode the OS-BPS power is managed, meaning if the power requirements of the switches becomes greater than what the OS-BPS can provide, the OS-BPS will manage the power and begin to shut down power based on connector priority. For additional information on connector priority refer to
“OS-BPS Connector Priority” on page 4-5
for more information.
Note. Do not change the power mode while the OS-BPS is providing power.

5 Managing Power over
Ethernet (PoE)
Power over Ethernet (PoE) provides inline power directly from the switch’s Ethernet. Powered Devices
(PDs) such as IP phones, wireless LAN stations, Ethernet hubs, and other access points can be plugged directly into the Ethernet. From these RJ-45 the devices receive both electrical power and data flow.
As the feature reduces devices’ dependence on conventional power sources, PoE eliminates many restrictions that traditional electrical considerations have imposed on networks.
In a PoE configuration, Power Source Equipment (PSE) detects the presence of a PD and provides an electrical current that is conducted along the data cable. The PD operates using the power received via the
Ethernet data cable; no connection to an additional power source (e.g., an AC wall socket) is required.
Note on Terminology. There are several general terms used to describe the feature, PoE. The terms Power over Ethernet (PoE), Power over LAN (PoL), Power on LAN (PoL), and Inline Power are synonymous terms used to describe the powering of attached devices via Ethernet. For consistency, this chapter and the
CLI Command Reference Guide refer to the feature as Power over Ethernet (PoE).
Additional terms, such as Powered Device (PD) and Power Source Equipment (PSE) are not synonymous with PoE, but are directly related to the feature:
•
PD refers to any attached device that uses a PoE data cable as its only source of power. Examples include access points, such as IP telephones, Ethernet hubs, wireless LAN stations, etc.
•
PSE refers to power sourcing equipment, which provides power to a single link section. PSE main functions include searching the PD, optionally classifying the PD, supplying power to the link section only if the PD is detected, monitoring the power on the link section, and scaling power back to detect level when power is no longer requested or required.
As the switches fully support 10/100/1000 Ethernet connectivity, you may also attach non-PD equipment, such as computer workstations, printers, servers, etc. to the PoE ports.
Important. Alcatel-Lucent recommends that PoE-enabled switches with attached IP telephones should have operational power supply redundancy at all times for 911 emergency requirements. In addition, both the switch and the power supply should be plugged into an Uninterruptible Power Source (UPS).

Note. PoE units support different wattage power supplies. If unlike power supplies are mixed or if an unsupported power supply (such as a 120W power supply) is used, a console message and a trap are generated.
PoE Class Detection
Powered devices can be classified into different classes as shown in the table below. Class detection allows for automatic maximum power adjustment based on the power class detected. This will prevent the switch from delivering more than the maximum power allowed based on a device’s class.
During class detection the switch will allocate the maximum amount of power allowed based on the class detected. Once powered, if the device uses less than the maximum the remaining power will be made available for other devices.

Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE)
Setting the PoE Operational Status
Enabling PoE
By default, Power over Ethernet is administratively enabled in the switch’s system software. However, in order to physically activate PoE, you must issue the lanpower start command on a slot-by-slot basis before any connected PDs will receive inline power.
To activate power to PoE-capable in a switch, enter the corresponding slot number only. For example:
-> lanpower start 3
If power to a particular port has been disconnected via the lanpower stop command, you can reactivate power to the port by specifying both the slot and port in the command line. For example:
-> lanpower start 3/11
Note. You cannot use the slot/port syntax to initially activate PoE on a port. This syntax is intended only to reactivate power to those that have been disconnected via the lanpower stop command. To initially activate PoE, you must use the lanpower start slot syntax only, as described above.
Disabling PoE
To disable PoE on a particular slot or port, use the lanpower stop command.
To disable PoE on a specific PoE-capable port, enter a slot/port number. For example:
-> lanpower stop 8/22
To disable PoE for all PoE-capable in a slot, enter the corresponding slot number only.
For example:
-> lanpower stop 8
Configuring the Total Power Available to a Port
By default, each port is authorized by the system software to use up to a maximum amount of milliwatts to power any attached device.
You can either increase or decrease this value based on the allowed ranges specified in
“Managing Power over Ethernet (PoE).”
Increasing the total power available to an individual port may provide a more demanding Powered Device
(PD) with additional power required for operation. Decreasing the total power available to a port helps to preserve inline power and assists in the overall management of the switch’s power budget.
To increase or decrease the total power available to an individual port, use the lanpower power command.
Since you are setting the power allowance for an individual port, you must specify a slot/port number in the command line. For example, the syntax
-> lanpower 3/12 power 3000 reduces the power allowance on slot 3 port 12 to 3000 milliwatts. This new value is now the maximum amount of power the port can use to power any attached device (until the value is modified by the user).

January 2013
Managing Power over Ethernet (PoE) Configuring Power over Ethernet Parameters
Configuring the Total Power Available to a slot
Like the maximum port power allowance, the system software also provides a maximum slot-wide power allowance. By default, each slot is authorized by the system software to use a number of watts to power all devices connected to its ports depending on which power supply is used.
As with the maximum port power allowance, the user can either increase or decrease this value based on the allowed ranges specified in
Chapter 5, “Managing Power over Ethernet (PoE).”
Note: Increasing or decreasing the total power available to a slot is designed for use on chassis-based products which share PoE power among the slots. For stackable products this command has no affect on other stack elements since each switch has a dedicated power supply.
Important. Decreasing the slot-wide power could cause lower priority ports to lose power if the new value is less than the total PoE power currently being consumed.
To increase or decrease the total power available to a slot, use the lanpower maxpower command. Since you are setting the power allowance for an individual slot, you must specify a slot number in the command line. For example, the syntax
-> lanpower 3 maxpower 80 reduces the power allowance of slot 3 to 80 watts. This value is now the maximum amount of power the slot can use to power all attached devices (until the value is modified by the user).
Note. Changing the maximum power available to a slot or port does not reserve or immediately allocate that power. These settings are only used for configuring a maximum amount of power that may be used, any unused power is still available and remains a part of the overall PoE budget.
Setting Port Priority Levels
As not all Powered Devices (PDs) connected to the switch have the same priority within a network setting, the OmniSwitch allows the administrator to specify priority levels on a port-by-port basis. Priority levels include low, high, and critical. The default priority level for a port is low.
•
Low. This default value is used for port(s) that have low-priority devices attached. In the event of a power management issue, inline power to low-priority is interrupted first (i.e., before critical and highpriority).
•
High. This value is used for port(s) that have important, but not mission-critical, devices attached. If other ports in the chassis have been configured as critical, inline power to high-priority is given second priority.
•
Critical. This value is used for port(s) that have mission-critical devices attached, and therefore require top (i.e., critical) priority. In the event of a power management issue, inline power to critical is maintained as long as possible.
To change the priority level for a particular port, use the lanpower priority
command. Since the switch allows you to set priority levels on a port-by-port basis, be sure to specify slot/port information in the command line. For example, the syntax
-> lanpower 8/22 priority critical
OmniSwitch 6850E Series Hardware Users Guide
January 2013
page 5-7
Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE) changes the priority value of port 22 of the OmniSwitch slot 8 to the highest priority level of critical. Now that the default value has been reconfigured, this port should be reserved for those PDs that are mission critical for network operations.
Setting the Capacitor Detection Method
By default, the PowerDsine capacitor detection method is disabled. To enable it, use the lanpower capacitor-detection
command by entering lanpower capacitor-detection followed by the slot number of the switch and enable.
For example, to enable the capacitor detection method on the switch with slot number 2, enter:
-> lanpower capacitor-detection 2 enable
To disable it, use the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the slot number and disable.
For example, to disable the capacitor detection method on slot number 2, enter:
-> lanpower capacitor-detection 2 disable
Note. The capacitive detection method should only be enabled to support legacy IP phones. This feature is not compatible with IEEE specifications. Please contact your Alcatel-Lucent sales engineer or Customer
Support representative to find out which Alcatel-Lucent IP phones models need capacitive detection enabled.

Managing Power over Ethernet (PoE) Understanding Priority Disconnect
Understanding Priority Disconnect
The priority disconnect function differs from the port priority function described on
applies only to the addition of powered devices (PDs) in tight power budget conditions. Priority disconnect is used by the system software in determining whether an incoming PD will be granted or denied power when there are too few watts remaining in the PoE power budget for an additional device. For example, if there are only 2 watts available in the current PoE power budget and a user plugs a 3.5W powered device into a PoE port, the system software must determine whether the device will be powered on. Based on priority disconnect rules, in some cases one or more existing devices may be powered down in order to accommodate the incoming device. In other cases, the incoming device will be denied power.
Priority disconnect rules involve the port priority status of an incoming device (i.e., low, high, and critical), as well as the port’s physical port number (i.e., 1–24). Understanding priority disconnect rules is especially helpful in avoiding power budget deficits and the unintentional shutdown of mission-critical devices when PDs are being added in tight power budget conditions. For detailed information on how priority disconnect uses port priority and port number criteria for determining the power status of incoming PDs, refer to the illustrated examples on pages
Reminder. Priority disconnect applies only when there is inadequate power remaining in the power budget for an incoming device.
For information on setting the priority disconnect status, refer to the section below. For information on setting the port priority status (a separate function from priority disconnect), refer to
.
Setting Priority Disconnect Status
By default, priority disconnect is enabled in the switch’s system software. For information on changing the priority disconnect status, refer to the information below.
Disabling Priority Disconnect
When priority disconnect is disabled and there is inadequate power in the budget for an additional device, power will be denied to any incoming PD, regardless of its port priority status (i.e., low, high, and critical) or physical port number (i.e., 1–24).
To disable priority disconnect, use the lanpower priority-disconnect command. Since the switch allows you to set priority disconnect status on a slot-by-slot basis, be sure to specify the slot number in the command line. For example, the syntax
-> lanpower 2 priority-disconnect disable disables the priority disconnect function on slot 2.
Enabling Priority Disconnect
To enable priority disconnect, use the lanpower priority-disconnect command. Be sure to specify the slot number in the command line. For example, the syntax
-> lanpower 8 priority-disconnect enable enables priority disconnect on slot 8.

Understanding Priority Disconnect Managing Power over Ethernet (PoE)
Priority Disconnect is Enabled; Same Priority Level on All PD
Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device.
When a PD is being connected to a port with the same priority level as all other in the slot, the physical port number is used to determine whether the incoming PD will be granted or denied power. Due to the support of different PoE standards and PoE hardware on each platform the internal port priority is different for each platform. The following tables should be used to determine PoE priority:
OS6850E Physical Port - 24 Port Models
OS6850E Physical Port - 48 Port Models
24 (Highest) -> 1 (Lowest)
48 (Highest) -> 1 (Lowest)
PoE Physical Port Priority
Priority Disconnect is Enabled; Incoming PD Port has Highest Priority Level
Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device.
When a PD is being connected to a port with a higher priority level than all other in the slot, the incoming
PD will automatically be granted power over the other devices, regardless of its physical port number.
In order to avoid a power budget deficit, another port in the slot is disconnected. In determining which port to power off, the system software first selects the port with the lowest configured priority level. For example, if a critical priority device is being added to a slot in which five existing devices are attached to high priority and one device is attached to a low priority port, the low priority port is automatically disconnected, regardless of its physical port number.
If all existing devices are attached to with the same lower priority level, the system software disconnects the port with both the lowest priority level and the highest priority physical port number. For example, if a critical priority device is being added to a slot in which six existing devices are attached to high priority, the high priority port with the lowest physical port priority number is automatically disconnected.
Priority Disconnect is Enabled; Incoming PD Port has Lowest Priority Level
Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device.
When a PD is being connected to a port with a lower priority level than all other in the slot, the incoming
PD will be denied power, regardless of its physical port number. Devices connected to other higher-priority will continue operating without interruption.

OmniSwitch 6850E Series Stack Overview Managing OmniSwitch 6850E Series Stacks
OmniSwitch 6850E Series Stack Overview
Users can configure up to eight switches, in any combination of chassis types, into a single virtual chassis known as a stack. With stacks, switching capacity can be easily expanded simply by adding additional switches to the stack. For example, a user can start with a stack composed of two switches and add up to six additional switches to that stack as network demands increase over time.
Note. Switches should be added one at a time in a stack.
Stacks also provide enhanced resiliency and redundancy features. If a switch in a stack goes down or is taken offline, the other elements in the stack will continue to operate without disruption. In addition, when a switch auto-synchronizes at boot-up, or if the user manually synchronize the switches (see
“Synchronizing Switches in a Stack” on page 6-37
for more information), operating software and configuration parameters are backed up on all switches in the stack. As a result, the original operating software and configuration parameters can be easily recovered if corrupted or otherwise lost.
Note on Terminology. The terms stack and virtual chassis are interchangeable referring to switches in a stacked configuration. The terms module, switch, slot, and element are used to refer to individual switches within a stacked configuration. The terms Chassis Management Module (CMM) and management module refer to those switches operating in a stack either in the primary or secondary management roles. Switches operating in an idle role are essentially acting as network interface modules and therefore may be referred to as Network Interfaces (NIs).
Roles Within the Stack
In order to operate as a virtual chassis, switches within a stack are assigned specific roles. These roles include primary and secondary management roles, idle status, and pass-through. For detailed descriptions of each of these roles, including their practical functions within the virtual chassis, refer to the sections below.
Primary and Secondary Management Modules
When switches operate in a stack, one switch in the stack always assumes the primary management role.
This primary element is responsible for functions, such as software and configuration management, webbased management (i.e., WebView), SNMP management, switch diagnostics, and software rollback.
One additional switch in the stack operates in a secondary management role. This switch serves as a backup, and is always ready to assume the primary management role in the stack if the switch with the primary role fails or is taken offline for any reason.
Since the secondary module quickly and automatically assumes management responsibilities, switches operating in idle mode elsewhere in the stack continue to pass traffic without disruption. This redundancy provides effective safeguards for mission-critical network traffic and is one of the stack’s most important failover features. Diagrams showing the management module failover sequence for stacks of three or more switches and stacks of two switches are provided on pages
, respectively.

Managing OmniSwitch 6850E Series Stacks Roles Within the Stack
Primary Management Module Selection
For a stack of switches to operate as a virtual chassis, there must be a mechanism for dynamically selecting the switch within the stack that will assume the primary management role. OmniSwitches use three different methods for selecting the primary switch. These methods are:
•
Chassis MAC address
•
Saved slot number
•
Chassis uptime
Note. Information on secondary management module selection is provided on
dynamic assignment of idle module roles is provided on page 6-12
.
Using the Chassis MAC Address
By default, the primary management role will be given to the switch with the lowest chassis MAC address. However, for this to occur, all switches in the stack must be booted within 15 seconds of each other. In addition, switches in the stack must have no preconfigured slot information. Because of these two conditions, the MAC address method for selecting the primary module usually occurs with new “out of the box” switches, or switches from which any preconfigured slot information has been cleared.
For more information on using the lowest MAC address to determine the primary switch in a stack, refer to the diagram below:
1
A stack of four switches is booted. All switches are powered on within 15 seconds of each other. In addition, there is no preconfigured slot information on any of the switches.

00:d0:95:b2:1c:ff
00:d0:95:b2:5b:8d
2
When the stack is booted, system software detects the lowest
MAC address. In this stacked configuration, the lowest
MAC address is 00:d0:95:b2:1c:ff.

The system software immediately assigns the corresponding switch the primary management role. When the switch is assigned as primary, it is also dynamically assigned the lowest slot number in the stack—i.e., slot 1. This slot number information is saved to the boot.slot.cfg file, located in the switch’s /flash file directory.
Primary Management Module Selection Using the Lowest Chassis MAC Address
Note. During the boot process, all other switches in the stack are also dynamically assigned unique slot numbers. As with the primary switch, these slot numbers are saved to the boot.slot.cfg file, located in the
/flash file directory of each switch. For more information on dynamic slot number assignment, refer to
.
OmniSwitch 6850E Series Hardware Users Guide
January 2013
page 6-7
Roles Within the Stack Managing OmniSwitch 6850E Series Stacks
Using Saved Slot Information
The saved slot number is the slot number the switch will assume following a reboot. This information is stored in a switch’s boot.slot.cfg file; the switch reads its slot number assignment from this file at bootup and assumes the specified slot number within the stack.
If switches in a stacked configuration have no preconfigured slot assignments, the slot number for each switch is dynamically assigned by the system software. Slot numbers can also be manually assigned by the user. For more information on manually assigning slot numbers, refer to
“Manual Slot Number Assignment” on page 6-23 .
When a stack with preconfigured slot information is booted, it is not the lowest MAC address that determines the primary management module. Instead, the slot information stored in each switch’s boot.slot.cfg is read by the system software and used in determining the primary. The switch with the lowest saved slot number becomes the primary management module.
Note. Although, for ease-of-management purposes, it is recommended that slot numbers are assigned beginning with slot number 1, it is not a requirement. In other words, a stack of four switches can have slot assignments 3, 4, 5, and 6. However, it is important that each element in a stack is assigned a unique slot number. Do not assign duplicate slot numbers to elements in a stack. Otherwise, one or more switches will be forced into pass-through mode. For more information on pass-through mode, refer to
.

Managing OmniSwitch 6850E Series Stacks Roles Within the Stack
Using Switch Uptime
A user can override both the MAC address and saved slot methods for determining a stack’s primary management module. This is done by controlling the uptime of switches in the stack. If all elements of a stack are powered off, the user can force a particular switch to become primary by powering on that switch and waiting a minimum of 15 seconds before powering on any other switches. This can be useful if the user wants a switch placed in a specific location, e.g., the top-most switch in a stack, to become the primary.
As with the lowest MAC address method, the primary management module is dynamically assigned slot number 1 when the stack is booted.
For more information on using saved slot information to determine the primary switch in a stack, refer to the diagram below:

The user allows a minimum of 15 seconds to pass. Because no other switches have joined the stack, the switch that was powered on considers itself a stand-alone. The switch assumes a primary role by default—even if there is a high saved slot number in its boot.slot.cfg file (e.g., 8).
The user now powers on the remaining switches in the stack in short succession.
4
In this example, when the remaining switches come online, each has a lower saved slot value than the switch powered on at step 1. However, the switch powered on at step 1—with its slot value of 8—retains its primary management role. The joining switches are essentially ineligible for primary status because they are considered “late arrivals.”
For the primary switch to forfeit its role to the switch with the lowest assigned slot number (in this case, slot number 1), the stack must be rebooted by the user either by issuing the reload all command or by powering off and powering on all switches in close succession.

Secondary Management Module Selection
In order to provide effective management module redundancy, all stacked configurations dynamically assign a backup, or secondary, management module during the boot process. Stacks use two different methods for selecting the secondary switch. These methods are:
•
Stacking connection to the primary switch
•
Saved slot number
Using the Stacking Connection to the Primary Switch
By default, the switch that is connected to the primary switch’s stacking port A is automatically assigned the secondary management role. This applies to stacks on which there is no preassigned slot information— i.e., there is no boot.slot.cfg file present in any switch.

The switch with the lowest assigned slot number automatically assumes the primary management role. The switch with the second lowest assigned slot number becomes the secondary management role, regardless of whether it is attached to stacking port A of the primary switch. In this case, the switch assigned slot 2 has the second-lowest slot number in the stack and becomes the secondary management module.
Secondary Management Module Selection Using Saved Slot Information
Reminder. Each element in a stack should always be assigned a unique slot number. Do not assign duplicate slot numbers to elements in a stack. Otherwise, one or more switches will be forced into
pass-through mode. For more information on pass-through mode, refer to page 6-13 .

Roles Within the Stack Managing OmniSwitch 6850E Series Stacks
Idle Module Role
Switches that are not assigned either the primary or secondary role in a stack are, by default, assigned the role of idle modules. These idle modules operate similarly to Network Interface (NI) modules in a chassisbased switch.
In the event of a management module failure within the stack, the idle module with the next lowest slot number in the stack will automatically assume the secondary management role. In other words, if the primary module in a stack goes down for any reason and the secondary takes over the primary management role, the switch must now assign a new secondary module. The idle element with the next lowest slot number assumes this new responsibility until the situation is corrected and all elements in the stack are reloaded.
Note. Primary and secondary management modules also send and receive traffic on their Ethernet ports.
The primary management module is like an NI module with the added task of overall stack management; the secondary management module is like an NI with the added responsibility of backing up the primary module in the event of a primary module failure. In other words, all modules in the virtual chassis can send and receive user data, regardless of their roles.
For more information on dynamic assignment of idle modules in a stack, refer to the diagram below:

The system software automatically assigns the remaining elements in the stack the idle module role. These modules act as Network
Interface (NI) modules, sending and receiving 10/100/1000
Ethernet traffic on their ports.
In the event of a primary-to-secondary failover, the idle module with the next-lowest slot number in the stack will assume the secondary—or backup—management role.

Managing OmniSwitch 6850E Series Stacks Roles Within the Stack
Pass-Through Mode
The pass-through mode is a state in which a switch has attempted to join a stack but has been denied primary, secondary, and idle status. When a switch is in the pass-through mode, its Ethernet are brought down (i.e, they cannot pass traffic). Its stacking cable connections remain fully functional and can pass traffic through to other switches in the stack. In this way, the pass-through mode provides a mechanism to prevent the stack ring from being broken. However, note that when a switch comes up in pass-through mode, it should not be left unresolved. Pass-through mode is essentially an error state that should be corrected immediately by the user.
Note. When a switch is in pass-through mode, its information will not display in hardware monitoring commands such as show chassis, show ni, show module, etc.
Conditions that can trigger a switch to enter pass-through mode include:
•
Duplicate slot numbers or incorrect stacking modes have been assigned within the stack
•
The user has manually forced the switch into pass-through mode using the stack clear slot command
Note. If a switch is forced into pass-through mode, the rest of the stack will not be disrupted. Any elements in the stack not operating in pass-through mode continue to operate normally.
The most common reason for one or more switches to enter pass-through is duplicate slot number assignments within the stack. So, in order to avoid pass-through mode, it is useful to keep track of the current saved slot numbers on all elements in the stack. Slot number assignments are stored in the boot.slot.cfg file in the /flash directory of each switch.
If the stack is booted and the same slot number is discovered on two or more switches, the switch with the lowest MAC address is allowed to come up and operate normally. Meanwhile, switches with the duplicate slot number and a higher MAC address come up in pass-through mode. To check the current slot number stored in each switch’s boot.slot.cfg file, use the show stack topology command. For example:
-> show stack topology
Link A Link A Link B Link B
NI Role State Saved Link A Remote Remote Link B Remote Remote
Slot State NI Port State NI Port
----+-----------+--------+------+-------+-------+-------+-------+-------+-------
1 PRIMARY RUNNING 1 UP 3 StackA UP 2 StackA
2 SECONDARY RUNNING 2 UP 1 StackB UP 3 StackB
3 IDLE RUNNING 2 UP 1 StackA UP 2 StackB
In this example, note that both slots 2 and 3 have a saved slot value of 2. If this stack is rebooted, a duplicate slot error will occur and the switch with the lower MAC address will be given the secondary management role. The slot with the higher MAC address will be forced into the pass-through mode.

Roles Within the Stack Managing OmniSwitch 6850E Series Stacks
To avoid a pass-through condition following a reboot, make sure that all saved slot values for the stack are unique. Use the stack set slot command. For example, change the saved slot value for the idle switch in slot 3 from 2 to 3:
-> stack set slot 3 saved-slot 2
Use the show stack topology command to verify the change:
-> show stack topology
Link A Link A Link B Link B

2 SECONDARY RUNNING 2 UP 1 StackB UP 3 StackB
3 IDLE RUNNING 3 UP 1 StackA UP 2 StackB
Recovering from Pass-Through Mode (Duplicate Slot Numbers)
The first step in recovering from pass-through is to determine which modules are currently operating in pass-through, as well as the reason for the pass-through state. To view this information, use the show stack topology command. For example:
-> show stack topology
Link A Link A Link B Link B
NI Role State Saved Link A Remote Remote Link B Remote Remote
Slot State NI Port State NI Port
----+-----------+--------+------+-------+-------+-------+-------+-------+-------

2 SECONDARY RUNNING 2 UP 1 StackB UP 1001 StackB
1001 PASS-THRU DUP-SLOT 2 UP 1 StackA UP 2 StackB
Switches operating in pass-through mode are given distinct slot numbers. These slot numbers are not related to their position in the stack. Instead, they are assigned the prefix “100,” followed by the numerical order in which they were forced into pass-through (1001–1008).
Note. For pass-through elements 1001 through 1008, the slot indicator LED on the chassis front panel blinks 1 through 8, respectively. For example, if a module enters pass-through and has the slot number
1004, the LED for the module blinks the number 4. For more information on the slot indicator LED, refer to “Status LEDs” on page 2-53 .
In the example above, the switch with the NI (i.e., slot) number 1001 is operating in pass-through. Note that the role assignment is PASS-THRU; also, the state displays DUP-SLOT, or duplicate slot number.
This can be further verified by looking down the saved slot column in the table. Note that slot 2, operating in the secondary management role, has a saved slot value of 2. Slot 1001, operating in pass-through, also has a saved slot value of 2. page 6-14 OmniSwitch 6850E Series Hardware Users Guide
January 2013
Managing OmniSwitch 6850E Series Stacks Roles Within the Stack
To resolve this pass-through condition, simply assign slot 1001 a new saved slot value and reboot the module. This can be done in either of two ways:
•
Use the stack set slot command to assign the new value, then use the reload pass-through command to reboot the module:
-> stack set slot 1001 saved-slot 3
-> reload pass-through 1001
•
Use the stack set slot command to assign the new slot value and, using the optional reload syntax in the command line, reboot the module:
-> stack set slot 1001 saved-slot 3 reload
When the module comes up, it assumes the new, unique slot position—in this case, slot 3—and, because it now has the highest slot number in the stack, it assumes an idle role (leaving the primary and secondary roles to slots 1 and 2, respectively). There are now no duplicate numbers in the stack and all elements are operating normally:

Roles Within the Stack Managing OmniSwitch 6850E Series Stacks
In some pass-through conditions (for example, larger stacks where multiple switches are in pass-through mode), it might be desirable to correct any duplicate saved slot assignments and then reboot the entire stack. The recovery from pass-through can be accomplished with fewer steps than reassigning slot numbers and rebooting modules on a slot-by-slot basis. However, be sure that there is no mission-critical traffic being passed on the non-pass-though modules; traffic will be interrupted on these modules during the reboot.
The following example shows a large stack with multiple elements operating in pass-through mode:
-> show stack topology
Link A Link A Link B Link B
NI Role State Saved Link A Remote Remote Link B Remote Remote

1 PRIMARY RUNNING 1 UP 3 StackB UP 1002 StackA
3 IDLE RUNNING 3 UP 4 StackB UP 1 StackA
This disordered stack topology, with its three modules operating in pass-through mode, can be corrected by entering the following commands:
-> stack set slot 4 saved-slot 1
-> stack set slot 5 saved-slot 2
-> stack set slot 1001 saved-slot 3
-> stack set slot 2 saved-slot 4
-> stack set slot 1003 saved-slot 5
-> stack set slot 1002 saved-slot 6
-> stack set slot 1 saved-slot 7
-> stack set slot 3 saved-slot 8
-> reload all
When all elements in the stack come up following the reboot, there are no longer any duplicate slot numbers in the stack. In addition, the stack topology is more orderly and, as a result, easier to manage:

Managing OmniSwitch 6850E Series Stacks Stack Cabling
Stack Cabling
Switches in a stack are connected to each other by stacking cables. The stacking cables come in various
in a stack.
Stacking cables for 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. In addition, for a stack to have effective redundancy, a redundant stacking cable must be installed between the upper-most and bottom-most switch at all times. This provides effective failover in the event of a stacking link or module failure within the stack.
The diagram below shows two recommended stacking cable patterns. For detailed information on assembling a stack and connecting the cables, refer to Chapter 2, “OmniSwitch 6850 Series Chassis and Hardware Components.”
Note. When planning the stack cabling configuration, keep in mind that the switch connected to stacking port A of the primary switch will be assigned the secondary management role by default.
A B
A stack of eight switches in a crossed (stacking port
A to stacking port B) configuration. Note that a redundant stacking cable connection exists between the top and bottom switches. This connection is required for effective redundancy across the stack.

Redundant Stacking Cable Connection
OmniSwitches allow redundant stacking cable connections between the top-most and bottom-most switches in a stack.
Important. For a stacked configuration to have effective redundancy, a redundant stacking cable must be installed between the upper-most and bottom-most switch in the chassis at all times.
The figure below shows how the redundant connection between the top and bottom switches in the stack ensures that data will continue to flow throughout the stack, even in the event of a connection failure at one of the stacking cables.

The stacking connection between slots 1 and 2 goes down unexpectedly. Data can no longer travel directly between slot 1 and 2.
However, because there is a redundant connection (the cable between slot 1 and slot 4), data is immediately passed to slot 4, then quickly traverses slot 3 and exits slot 2 to its destination.

Redundant stacking cables provide a form of dual redundancy. As shown in the figure above, the redundant cable allows traffic to flow in the event of a stacking link failure. The redundant cable also provides failover if a switch goes down within the stack. Traffic continues to flow between the modules that remain operational, as shown in the diagram below:

Checking Redundant Stacking Cable Status
To check whether a redundant stacking cable connection exists between the top-most and bottom-most switches in the stack, use the show stack status command. For example:
-> show stack status
Redundant cable status : present
Tokens used : 12
Tokens available : 20
In this example, a redundant stacking cable connection is present between the top-most and bottom-most switches in the stack.

Slot Numbering Managing OmniSwitch 6850E Series Stacks
Slot Numbering
For a stack of switches to operate as a virtual chassis, each module in the stack must be assigned a unique slot number. To view the current slot assignments for a stack, use the show ni or show module commands. The slot number is also displayed on the front panel of each switch by the LED located on the left side of the chassis (refer to “Status LEDs” on page 2-53 for more information).
There are two ways stacking modules are assigned slot numbers:
•
Dynamic slot number assignment by the system software
•
Manual slot number assignment by the user page 6-20 OmniSwitch 6850E Series Hardware Users Guide
January 2013
Managing OmniSwitch 6850E Series Stacks Slot Numbering
Dynamic Slot Number Assignment
Dynamic slot number assignment occurs when there are no boot.slot.cfg files present in the switches’
/flash directories. This is the case for new, “out of the box,” switches that have not been previously booted.
When a brand new stack (or stack with no boot.slot.cfg files) is booted, the system software automatically detects the module with the lowest MAC address. This module is assigned the primary management role (see
) 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. Refer to the diagrams below for more information on dynamic slot numbering.
Note. As the slot numbers are dynamically assigned, boot.slot.cfg files are auto-generated in the /flash directory of each switch. When modules are subsequently booted, each switch reads its slot number assignment from this file and comes up accordingly.
Slot 6 - Idle
Slot 7 - Idle
Slot 8 - Idle
Slot 1 - Primary
Slot 2 - Secondary
Slot 3 - Idle
Slot 4 - Idle
Slot 5 - Idle
In this example, 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.
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.
Dynamic Slot Numbering Example 1

page 6-21
Slot Numbering Managing OmniSwitch 6850E Series Stacks
If the switch with the lowest MAC address happens to be the bottom-most module in the stack, slot numbering will not resume from the top of the stack. Instead, the system software will select the secondary module using the standard method (i.e., the switch connected to the primary’s stacking port A), then continue to number the stack from the bottom up. This intuitive slot assignment provides the cleanest and most manageable stack topology. Refer to the diagram below for more information:
Slot 8 - Idle
Slot 7 - Idle
Slot 6 - Idle
Slot 5 - Idle
Slot 4 - Idle
Slot 3 - Idle
Slot 2 - Secondary
Slot 1 - Primary
In this example, the bottom switch 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.
The switch immediately above 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 then sequentially assigns slot numbers up the stack. In other words, the switch immediately above slot 2 is assigned the slot number 3; the switch immediately above slot 3 is assigned the slot number 4, and so on. This default procedure ensures the most ordered and manageable stack topology out of the box.

Managing OmniSwitch 6850E Series Stacks Slot Numbering
Manual Slot Number Assignment
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.
Manually assigning slot numbers can be useful in reordering existing slot numbers in order to create a sequential numbering scheme from the top of the stack to the bottom (or vice-versa). Refer to the following example:
Slot 6 - Idle
Slot 7 - Idle
Slot 8 - Idle
Slot 1 - Primary
Slot 2 - Secondary
Slot 3 - Idle
Slot 4 - Idle
Slot 5 - Idle
This example, taken from
, 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. This is accomplished by entering the following commands:
-> 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
-> 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.
Note that the modules were not reloaded one-by-one, even though the stack set slot command provides optional syntax for doing so. Instead, new slot number information is first saved to each boot.slot.cfg file across the stack. The reboot is saved for last in order to avoid duplicate slot numbers within the stack, which would cause unwanted pass-though mode conditions (see
).
OmniSwitch 6850E Series Hardware Users Guide

Slot Numbering Managing OmniSwitch 6850E Series Stacks
When the stack comes up following the reboot, the manually-configured slot numbers display as follows:
Slot 1 - Primary
Slot 2 - Secondary
Slot 3 - Idle
Slot 4 - Idle
Slot 5 - Idle
Slot 6 - Idle
Slot 7 - Idle
Slot 8 - Idle
The stack set slot command can also be used to manually correct duplicate saved slot assignments within
the stack topology. Refer to pages 6-13
through
6-15 for detailed information.
Reverting to the Dynamic Slot Numbering Model
To clear the boot.slot.cfg files from the stack’s /flash directories, use the stack clear slot command on all modules and then reboot the stack. For example:
-> stack clear slot 1
-> stack clear slot 2
-> stack clear slot 3
-> stack clear slot 4
-> stack clear slot 5
-> stack clear slot 6
-> stack clear slot 7
-> stack clear slot 8
-> reload all
The commands shown above clear the saved slot information from all modules in an eight-module stacked configuration and then reboot the stack. Because the system software no longer has preassigned slot information to read during the boot process, the stack uses the dynamic slot number assignment method described on

Managing OmniSwitch 6850E Series Stacks Hot-Swapping Modules In a Stack
Hot-Swapping Modules In a Stack
Modules within a virtual chassis are hot-swappable. NI modules are essentially those modules operating in the stack in idle mode. These modules can be removed from, or added to, an existing stack without disrupting other modules in the stack.
Removing Switches from an Existing Stack
When removing switches from an existing stack, observe the following important guidelines:
•
Do not attempt to hot-swap modules operating in primary or secondary management roles
•
Be sure the stacking cables and stacking cable redundancy are not disrupted
Hot-swapping is intended for switches in idle and, if applicable, pass-through status only. Removing primary or secondary management modules from a stack will trigger a failover sequence, i.e., one or more additional modules within the stack must reload in order to reassign the management roles. Whenever possible, avoid removing a switch that is operating as a primary or secondary management module.
Also, removing a switch from a stacked configuration can disrupt stack cabling at the rear of the stack.
When removing a module, be sure that stacking link integrity, including important stacking cable redundancy, is maintained between all remaining modules. For more information on stacking cable connec-
Inserting Switches Into an Existing Stack
When inserting switches into an existing stack, observe the following important guidelines:
•
Avoid duplicate saved slot numbers
•
Never attempt to operate more than eight switches in a single stack
•
Make sure all switches are running the same software version.
To avoid duplicate slot numbers, simply make sure that any modules being added to an existing stack have been cleared of preassigned slot information. In other words, verify that there is no boot.slot.cfg file present in the /flash directory of any switch being added. When the switch is connected to the existing stack and booted, the system software automatically assigns it a unique slot number. No duplicate slot errors occur.
Note. If it is preferable to add a switch with an existing boot.slot.cfg file to a stack, be sure that the saved slot number of the incoming switch is not already assigned to a switch operating in the stack.

Merging Stacks
Merging stacks involves connecting two or more operational stacks and attempting to reboot them as a single virtual chassis. In most cases, errors will result. To merge stacks without causing errors, select one stack that is to remain up and running and then add modules from the other stack(s) by following the steps below:
1
Make sure all switches are running the same software version.
2 Clear the saved slot information from all incoming modules. This will ensure that they are each assigned unique slot numbers when they join the stack.
3
After clearing the saved slot information, power off all incoming modules.
4 Connect the stacking cables for all incoming modules to the existing, operational stack as required. Be
sure to provide stacking cable redundancy. For information on stack cabling, refer to page 6-17 .
5
Power on all incoming modules.
Note. No more than eight switches can operate in a single stacked configuration at any time.

Managing OmniSwitch 6850E Series Stacks Reloading Switches
Reloading Switches
Reloading is essentially a soft boot of a switch. Users can reload stacked modules operating in any role— i.e., primary, secondary, idle, and pass-through. Refer to the sections below for more information.
Reloading the Primary Management Module
If the switch with the primary management role is reloaded, the switch with the secondary role automatically takes over primary management functions. In other words, the switch with the secondary role assumes the primary role as soon as the reload is initiated.
Meanwhile, the idle switch with the next lowest slot number automatically assumes the secondary role.
When the reloaded switch (the former primary module) comes back up, it assumes an idle role within the stack.
To reload the primary management module, use the reload command. The optional syntax primary can be used in the command line, but is not required. For example:
-> reload primary
Note. A primary management module reload can also be scheduled for a later time or date. For information on scheduling a primary module reload, as well as additional command details, refer to the

Meanwhile, the switch with the primary management role, as well as any other idle modules in the stack, continue operations without interruption.
To reload the secondary management module, use the reload command. Be sure to include the syntax secondary in the command line. For example:
-> reload secondary
Note. A secondary management module reload can also be scheduled for a later time or date. For information on scheduling a secondary module reload, as well as additional command details, refer to the
OmniSwitch CLI Reference Guide.

Reloading Switches with Idle Roles
Similar to reloading Network Interface (NI) modules on chassis-based switches modules operating in idle status within a stack can be reloaded via the CLI.
Note. Any traffic being passed on the module’s Ethernet will be interrupted during the reboot. Other modules within the stack will continue to operate without interruption.
To reset a single module operating in idle mode, use the reload ni
command. Be sure to include the slot number of the idle switch in the command line. For example:
-> reload ni 3
Only one idle switch can be reloaded at a time. In order to reload multiple idle switches at once, the entire stack must be reloaded using the reload all command.
After reloading a switch operating in an idle role, the switch resumes idle status when it comes back up, despite its saved slot number. In other words, if an idle switch with a saved slot number of 1 is reloaded, it resumes its previous idle role. Although it has the lowest possible saved slot number, it does not take over the primary management role. In order for this switch to take over the primary role, all switches in the stack must be reloaded.
tion on idle status, refer to page 6-12 .
Reloading Switches in Pass-Through Mode
Pass-through mode is a state in which a switch has attempted to join a stack but has been denied primary, secondary, and idle status. Because this is essentially an error state, the pass-through condition must be resolved and any modules operating in pass-through mode must be reloaded.
To reload a module operating in pass-through mode, use the reload pass-through
command. Be sure to include the slot number of the pass-through switch in the command line. For example:
-> reload pass-through 1001
Note. Before issuing the reload pass-through command, be sure to resolve any conditions causing the switch to operate in pass-through mode. Otherwise, the switch is likely to come up again in pass-through

Reloading Switches Managing OmniSwitch 6850E Series Stacks
Reloading All Switches in a Stack
Reloading all switches in the stack is essentially a full reboot of the virtual chassis. This can be useful in restoring a stack’s previously configured topology—i.e., the stack’s saved slot numbers and management roles. Note, however, that all data flow on the stack is interrupted whenever a full reboot is issued.
To reset all switches in a stack use the reload all command. For example:
-> reload all
Important. Before issuing the reload all command, be sure to read the sections below. Understanding topics such as software synchronization and the effects of saved slot information can help users avoid unexpected results following a full stack reboot.
Software Synchronization During a Full Reload
If the checksum value on the stack’s non-primary switches differs in any way from the checksum value on the primary switch, the primary switch automatically distributes its system and configuration software to all other switches in the stack whenever a full reload is executed.
During this automatic software synchronization, system and configuration software on the secondary and idle switches is overwritten. Because the primary switch’s “last known good” software is propagated to all switches, the synchronization process helps ensure effective redundancy across the stack.
Effects of Saved Slot Number Information on the Reload Process
Depending on the status of saved slot information across the stack, there are different slot numbering and management role scenarios that can occur following a full reboot. For this reason, checking the current stack topology before issuing a full reboot is strongly recommended. To check the current stack topology, use the show stack topology
command. Refer to the OmniSwitch CLI Reference Guide for detailed command information.
Possible saved slot number conditions include:
•
All switches have unique saved slot information
•
No switches in the stack have saved slot information
•
Some switches have saved slot information, others do not
•
Two or more switches have duplicate slot information
All Switches Have Unique Saved Slot Information
If a full reload is issued and all switches have unique slot numbers saved to their boot.slot.cfg files, the slot numbers will be assigned according to the saved slot information. The primary management role will be given to the switch with the lowest saved slot number. The secondary management role will be given to the switch with the second-lowest saved slot number. All other switches will be assigned to idle roles.
An illustrated example of this method for assigning slot numbers and management roles is provided on pages
.
page 6-32 OmniSwitch 6850E Series Hardware Users Guide
January 2013
Managing OmniSwitch 6850E Series Stacks Reloading Switches
No Switches In the Stack Have Saved Slot Information
If a full reload is issued and no switches in the stack have unique slot numbers, slot numbers will be assigned beginning with the switch with the lowest MAC address. (This can occur if the boot.slot.cfg file has been deleted from each switch’s /flash directory—e.g., by issuing the stack clear slot command for all modules in the stack.)
The switch with the lowest MAC address is assigned slot number 1 and given the primary management role. The switch connected to stacking port A of the primary switch is automatically assigned slot number 2 and given the secondary management role. Stack cabling is then used to determine the dynamic slot numbering of the remaining modules in the stack. The switch immediately adjacent to slot 2 is assigned slot number 3 and given an idle role, etc.
An illustrated example of this method for assigning slot numbers and management roles is provided on pages
.
Some Switches Have Saved Slot Information, Others Do Not
If only some switches in the stack have boot.slot.cfg files in their /flash directories, the system software will first read the contents of these files and then dynamically assigns unique slot numbers to any switches that do not have saved slot information. The primary management role will be given to the switch with the lowest saved slot number. The secondary management role will be given to the switch with the secondlowest saved slot number. All other switches will be assigned to idle roles.
When unique slot numbers are dynamically assigned by the system software, a boot.slot.cfg file is automatically generated with the new slot information. Because all switches now have unique saved slot information, any subsequent reload all commands issued will cause the stack to come up as described in the section,
“All Switches Have Unique Saved Slot Information” on page 6-32 .
Two or More Switches Have Duplicate Slot Information
If a full stack reboot is issued and the same slot number is found in the boot.slot.cfg file of two or more switches, the switch with the lowest MAC address is allowed to come up and operate normally. Meanwhile, any other switches with the duplicate slot number come up in pass-through mode.
The pass-through mode is essentially an error state in which a switch has been denied primary, secondary, and idle roles within the stack. When a switch is in pass-through mode, its Ethernet are brought down and cannot pass traffic. It is for this reason that users should always check the current saved slot number for each switch before issuing the reload all command. To check the current saved slot information across the stack, use the show stack topology
command. For detailed information on pass-through mode, refer to
“Pass-Through Mode” on page 6-13

Reloading Switches Managing OmniSwitch 6850E Series Stacks
Avoiding Split Stacks
The term “splitting” a stack refers to the creation of isolated modules within the virtual chassis. A split stack can result from the following conditions:
•
Two or more non-adjacent switches are reloaded simultaneously
•
The stack is reloaded without a redundant stacking cable connection
The sections below offer simple guidelines for avoiding splitting the stack during the reload process.
Do Not Reload Non-Adjacent Switches Simultaneously
If non-adjacent switches in the stack—for example, the top switch in the stack and the third-from-top switch in the stack—are reloaded simultaneously, a problem will occur. The switch between the two nonadjacent switches will become isolated and the virtual chassis will be effectively split.
To avoid splitting the stack, do not reload the two non-adjacent switches simultaneously. Instead, simply reload the top switch first, then reload the third-from-top switch, or vice-versa.
Be Sure a Redundant Stacking Cable is Installed at All Times
Another important guideline for avoiding split stacks involves the redundant stacking cable. In order to avoid isolated modules within the virtual chassis, simply make sure that a redundant stacking cable connection exists between the top-most and bottom-most switches at all times.
For more information on the redundant stacking cable connection, refer to

Managing OmniSwitch 6850E Series Stacks Changing the Secondary Module to Primary
Changing the Secondary Module to Primary
Stacks allow users to manually force the secondary switch to assume the primary management role. This is referred to as “takeover.” The behavior of a takeover is similar to that of reloading the primary management module (see
).
Whenever a takeover is initiated, the switch with the secondary role automatically takes over primary management functions. The primary switch is automatically reloaded and any traffic being passed on the primary switch’s Ethernet is interrupted.
Meanwhile, the idle switch with the next-lowest slot number automatically assumes the secondary role.
When the former primary module comes back up, it assumes an idle role within the stack.
To initiate a takeover sequence, use the takeover command. For example:
-> takeover
Note. Before using the takeover command, verify that the switches in the stack are synchronized.
Otherwise, data flow and switch management functions may be interrupted due to incorrect or outdated

Managing OmniSwitch 6850E Series Stacks Synchronizing Switches in a Stack
Synchronizing Switches in a Stack
Management module synchronization refers to the process of copying all files in the /flash/working and
/flash/certified directories of the primary management module to the /flash/working and /flash/certified directories of all the other switches in the stack. The system and configuration software on the nonprimary switches—i.e., the secondary management module and any modules operating in idle—is overwritten.
The synchronization process ensures that the contents of these directories match exactly for all switches across the stack. This can be especially useful after new software has been loaded to the primary management module. Further, synchronization prevents any switch from assuming a management role within the stack with incorrect or outdated software or configuration files. Because the primary switch’s “last known good” software is propagated to all switches, the synchronization process helps ensure effective redundancy across the stack.
In order to maintain effective management module redundancy, switches in the stack must be synchronized at all times. To determine whether a stack is in need of synchronization, use the show runningdirectory command. For example:
-> show running-configuration
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 : NOT SYNCHRONIZED,
Running Configuration : NOT AVAILABLE,
Stacks Reload on Takeover: PRIMARY ONLY
This example shows a switch on which the /flash directories between the management modules are not synchronized. To manually synchronize all switches in the stack, enter the following command:
-> copy working certified flash-syncro
When the synchronization process is initiated, modules within the stack continue to operate without interruption and data flow across the stack is unaffected.
Automatic Synchronization During a Full Reload
If the checksum value on the stack’s non-primary switches differs in any way from the checksum value on the primary switch, the primary switch automatically distributes its system and configuration software to all other switches in the stack whenever a full reload is executed.
For more information on initiating a full reload, see
“Reloading All Switches in a Stack” on page 6-32 .
Note. For more information on management module synchronization and managing the /flash/working and /flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the Switch
