Availability Features Availability Features OmniSwitch 6855 switches incorporate advanced Alcatel-Lucent Operating System (AOS) protocols to ensure high availability for mission critical applications. 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.
OmniSwitch OS6855 Family 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 OK LED in addition to sending a trap.) LEDs LEDs, which provide visual status information, are provided on the chassis front panel.

7 Managing OmniSwitch 6855 Series Stacks In addition to their working as individual stand-alone switches, OmniSwitch 6855 Series switches can also be linked together to work as a single virtual chassis known as a stack. With stacks, users can easily expand their switching capacity simply by adding additional switches to the stack.
Note. You can also manage and monitor OmniSwitch 6855 Series stacks through WebView, Alcatel-Lucent’s embedded web-based device management application. WebView is an interactive and easy-to-use GUI that can be launched from OmniVista or a web browser. Please refer to WebView’s online documentation for more information.
Managing OmniSwitch 6855 Series Stacks OmniSwitch 6855 Stacking Specifications The following table lists OmniSwitch 6855 Stacking specifications. Models Supporting Stacking Maximum Switches in a Stack Stacking Cable Lengths - Copper Stacking Cable Lengths - Fiber (SFP+) Stacking / Uplink Port Default Mode Changing to Stacking Mode The OmniSwitch 6855-U24X SFP+ ports can be set to either stacking or uplink mode.
OmniSwitch 6855 Series Stack Overview OmniSwitch 6855 Series Stack Overview Users can configure OmniSwitch 6855-U24X switches 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 additional switches to that stack as network demands increase over time.

Managing OmniSwitch 6855 Series Stacks Important Note. For management module redundancy to work effectively, the software on all switches operating in the stack must be synchronized at all times. Refer to page 7-37 for more information. Primary Secondary Idle Idle Offline Secondary Idle...
Page 154
Roles Within the Stack Primary Secondary Offline Secondary Offline Primary Secondary Primary Redundant Management Module Failover (Two Switches) page 7-6 Managing OmniSwitch 6855 Series Stacks A stack of two OmniSwitches is operating normally. The stack consists of a primary module and a secondary module.
Managing OmniSwitch 6855 Series Stacks Primary Management Module Selection For a stack of OmniSwitches 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.
Page 156
Roles Within the Stack 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.
Page 157
Managing OmniSwitch 6855 Series Stacks 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.
Roles Within the Stack Secondary Management Module Selection In order to provide effective management module redundancy, all OmniSwitch stacked configurations dynamically assign a backup, or secondary, management module during the boot process. OmniSwitch stacks use two different methods for selecting the secondary switch. These methods are: •...
Page 159
Managing OmniSwitch 6855 Series Stacks Using Saved Slot Information If a stack with preassigned slot information for each switch is booted, the switch with the second lowest slot value is assigned the secondary management role. For example, if a stack of four switches is booted and the preassigned slot values for each switch are 1, 2, 3, and 4, the switch with the slot value of 2 is assigned the secondary role.
Roles Within the Stack 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 chassis- based switch.
Managing OmniSwitch 6855 Series Stacks 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).
Roles Within the Stack 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 slot 3 from 2 to 3: -> stack set slot 3 saved-slot 2 Use the show stack topology ->...
Page 163
Managing OmniSwitch 6855 Series Stacks 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 to reboot the module: ->...
Page 164
Roles Within the Stack 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.
Managing OmniSwitch 6855 Series Stacks Stack Cabling Switches in a stack are connected to each other with either copper or fiber stacking cables that are avail- able in various lengths. Fiber can be used with an SFP+ transceiver. Stacking cables for OmniSwitches 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.
Stack Cabling 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.
Managing OmniSwitch 6855 Series Stacks Redundant stacking cables provide a form of dual redundancy. As shown in the figure above, the redun- dant 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.
Slot Numbering Slot Numbering For a stack of OmniSwitches 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 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 There are two ways stacking modules are assigned slot numbers: •...
Managing OmniSwitch 6855 Series Stacks 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.
Page 170
Slot Numbering 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 second- ary 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.
Managing OmniSwitch 6855 Series Stacks Manual Slot Number Assignment To manually assign slot numbers to one or more modules in a stack, use the 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.
Slot Numbering 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.
Managing OmniSwitch 6855 Series Stacks Hot-Swapping Modules In a Stack As with chassis-based switches, NI modules within an OmniSwitch 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.
Hot-Swapping Modules In a 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: Make sure all switches are running the same software version.
Managing OmniSwitch 6855 Series Stacks 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 automati- cally takes over primary management functions.

Managing OmniSwitch 6855 Series Stacks Reloading the Secondary Management Module If the switch with secondary management role is reloaded, the idle switch with the lowest slot number will automatically assume the secondary role. The reloaded switch (the former secondary) will assume an idle role when it comes back up.

Managing OmniSwitch 6855 Series Stacks 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.
Reloading Switches 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.
Page 181
Managing OmniSwitch 6855 Series Stacks 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 modules in the stack.) The switch with the lowest MAC address is assigned slot number 1 and given the primary management...
Reloading Switches 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.
Managing OmniSwitch 6855 Series Stacks Changing the Secondary Module to Primary OmniSwitch stacks allow users to manually force the secondary switch to assume the primary manage- ment 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.
Page 184
Changing the Secondary Module to Primary If there are only two switches in the stack, the former primary switch resumes the secondary role when it comes back up following the takeover. Primary - Slot 1 Secondary - Slot 2 -> takeover Booting...
Managing OmniSwitch 6855 Series Stacks 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 non- primary switches—i.e., the secondary management module and any modules operating in idle—is over- written.
Monitoring the Stack Monitoring the Stack As shown in the previous sections, monitoring the current status and operation of all elements in a stack can help users avoid unexpected stack conditions. The table below includes CLI commands that are useful in monitoring stack conditions.
