Thank you for choosing a Linksys Ethernet switch. This Ethernet switch allows you to quickly
and easily expand your Linksys One system. It delivers non-blocking, wire speed switching
for your network clients, plus multiple options for connecting to your network backbone.
Twenty four ports wire up your workstations or connect to other Linksys switches or devices.
LED indicators provide power, link, and activity status.
The Ethernet switch features monitoring and configuration via the Linksys One Portal, your
web browser, or the console interface. If your Ethernet switch is part of a Linksys One system,
the easiest way to manage it is with the Linksys One Portal — available only on the Linksys
One Services Router. Refer to the Linksys One Customer Premises Equipment Administration Guide for more details on the Linksys One Portal.
The Ethernet switch supports numerous security features including the Remote Authorization
and Authentication (RADIUS) and Terminal Access Controller Access Control System
(TACACS+) protocols. With Simple Network Time Protocol (SNTP), the Ethernet switch can
synchronize its clock with a time server available on one of its attached networks.
The system is fully manageable using a combination of a database of MIB (Management
Information Base) variables, whose combined values represent all facets of the system state,
and the Simple Network Management Protocol (SNMP) protocol.
The “P” model of the Ethernet switch supports Power over Ethernet (PoE) which eliminates the
need to run 110/220 VAC power to wireless network, IP telephony, or other PoE powered
devices on the Linksys network. Use of a PoE system allows greater flexibility in locations of
network devices, and significantly decreasing installation costs. The entire PoE system can be
centrally powered by uninterruptible power supplies if necessary.

Connecting the Switch
Overview
This chapter will explain how to connect network devices to the Ethernet switch. For an
example of a possible network configuration, see the application diagrams shown below.
Before You Install the Switch...
When you choose a location for the Ethernet switch, observe the following guidelines:
•Make sure that the Ethernet switch will be accessible and that the cables can be easily
connected.
3
Chapter
•Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting
fixtures.
•Position the Ethernet switch away from water and moisture sources.
•To ensure adequate air flow, be sure to provide a minimum clearance of two inches
(50 mm) around the air intake and exhaust ports on the sides of the Ethernet switch.
•Do not stack free-standing Ethernet switches more than four units high. The stacking
configuration, described in ”Stacking Multiple Switches,” on page 12, allows up to eight
units to be logically stacked together. It is recommended that multiple Ethernet switches
be mounted in a rack when installed in this manner. Ethernet switches can be physically
placed at different locations; they do not have to be stacked at the same location.

Placement Options
Before connecting cables to the Ethernet switch, first you will physically install the Ethernet
switch. Either set the Ethernet switch on its four rubber feet for desktop placement, mount it in
a standard-sized, 19-inch wide for rack-mount placement, or mount it on a wall with the
wall-mount brackets provided.
NOTE: The four supplied mounting
brackets can be used for either wall
mount or rack mount installations.
Desktop Placement
1. Attach the rubber feet to the recessed areas on the bottom of the Ethernet switch.
2. Place the Ethernet switch on a desktop near an AC power source.
CAUTION: Keep enough ventilation
space for the Ethernet switch so it does
not exceed the environmental
restrictions mentioned in the
specifications.
Rack-Mount Placement
To mount the Ethernet switch in any standard-sized, 19-inch wide, (each Ethernet switch
requires 1RU of space in the rack), follow these instructions:
1. Remove the four front screws on one side of the Ethernet switch. Retain the screws for reinstallation.
2. Place one of the supplied spacers on the side of the Ethernet switch so the four holes
align to the screw holes.
3. Place a rack mount bracket next to the spacer and reinstall the four screws (removed in

Stacking Highlights
•In stacking mode, each Ethernet switch is
given a unique ID, from 1 to 8.
•Stack IDs 1 and 2 are Master-Enabled units.
•All Ethernet switches in the stack must run the
same version of software.
•The Stack Master switch maintains the
configuration.
•Stack cannot combine Linksys SFE2000 and
SGE2000 family Ethernet switches.
•By factory default, Ethernet switches boot in
stacking mode.
•Stack ID can be user assigned or
automatically assigned.
•Stacking ports are available to user in
standalone mode as regular network ports.
•Settings are applied only to the master unit;
certain changes take place only after reset.
Stacking Multiple Switches
The Stacking configuration provides multiple switch management through a single point as if
all stack master and stack members were a single Ethernet switch. All stack masters are
accessed through a single IP address through which the stack is managed. The stack can be
managed from the web-based interface or the console interface.
You can build stacks by building a new stack from a group of switches, or adding new units
to an existing stack. Stacks can be automatically or manually configured.
NOTE: Two ports of each unit in a stack mode (ports 12
and 24 on GE units, and ports G1 and G2 on FE units)
are reserved for stacking links, and cannot be used for
regular network connections.
Switch software is downloaded separately for each stack member. However, all units in the
stack must be running the same software version.
A stack unit can operate in one of the following modes:
•Stand-alone — A switch operating in standalone mode runs as an independent,
single unit. All ports of a standalone switch operate as normal Ethernet links. A
standalone switch does not participate in a stack even if physically connected to a
stack.
3
Chapter
•Stack — Indicates the device operates as a Stacked unit after the system is reset. A
switch operating in stack mode is not an independent unit, but a member of an
organized group of switches known as a stack. A stack consists of one Stack Master
control switch, one Master Backup switch and up to six Stack Member switches. In
some cases, a unit that is not connected to any other units may operate as a “stack–
of-one.”
The Stack Master unit manages the stack and is responsible for the configuration. The Master
Backup Runs as a slave unit and monitors the operation of the stack master. A stack member
runs a slave version of the switching algorithm, which allows the applications running on the
master unit to control the resources of the member unit.

Linksys One Ready Communications Solution
By default, the Ethernet switch is in stacking mode. Using the console interface or the web
interface, you can change the mode to standalone mode.
TIP: Power the Ethernet switches in the
order that you want them in the Stack
ID. The first powered Ethernet switch in
a stack is assigned as the Master Unit,
the next powered unit is assigned as the
Master-Backup. The remaining units are
assigned Stack IDs in the order that they
are powered.
When the device is in standalone mode, the stacking ports can be used as regular ports.
Connecting Cabling for Stacking
When the Ethernet switch is in stacking mode, ports G1 – G2 (copper Gigabit Ethernet
ports) are reserved as stacking ports and cannot be used as network ports. In this case,
either fiber or copper ports can be used for stacking.

Managing Stacks
Building Automatically-Configured Stacks
Building a New Stack
The easiest way to build a stack is to use a group of switches, each of which is in factory
default mode:
NOTE: If the units to be used in building the new stack
have been used previously, we recommend that you reset
them to the factory default by holding the reset button for
at least 10 seconds before using them.
8. Connect the units physically through the stacking ports, using standard Ethernet cables.
9. Power the units on. After a short interval the stack becomes operational, with one of the
units selected as the Stack Master. The unit selected as Stack Master is indicated by a lit
green “MST” LED on its front panel. If a serial console connection is desired, the serial
cable should be connected to the console port of the unit serving as the Stack Master.
Adding Units to a Running Stack
1. Reset the units that will be added by restoring them to the factory default mode. Connect the
units physically to the stack.
3
Chapter
2. Power the units on. After a short interval, they will become members of the stack.
Building Manually-Configured Stacks
You can manually configure stacks, including choosing a specific unit as the Stack Master.
You must assign a unique Unit ID (from 1 to 8) to each stack member.
Building a New Stack
1. Reset all relevant units to by restoring them to the factory default mode.
2. Connect the units physically through the stacking ports, using standard Ethernet cables.
3. Assign each unit its desired number, making sure no duplicates exist, and reset the stack.

Adding Units to a Running Stack
1. Reset the units to be added by restoring them to the factory default mode.
2. Connect the units physically to the stack.
3. Power the units on. After a short interval, they will become stack members, but will have
automatically-assigned Unit IDs. Assign each such unit its desired Unit ID (using the
Stack Management Interface through the console port, by Telnet, or by using the
graphical user interface (GUI).
4. Reset the units to make this assignment permanent.
NOTE: We recommended that if you manually assign a
Unit ID to one unit, you manually assign Unit IDs to all
units. Using a mix of both system-assigned and manuallyassigned IDs in your network can impact system
performance.
5. The unit that is assigned the Unit ID 1 is the Stack Master, and its front panel “MST” LED
lights green. The unit assigned the Unit ID 2 is the Backup Master.
Understanding Stack Resiliency
Stacks can be configured in ring or chain topologies. We recommend configuring the stack
in ring topology, due to the high resiliency in case of unit failure or stacking links failure.
Additionally, if a redundant power supply is present, we recommend connecting the Stack
Master and Backup Master units to the redundant power supply.
Understanding Advanced Stacking
To understand advanced stacking, you must understand Unit IDs and how they are
allocated, and the stack unit startup process.
Unit IDs
Each unit in a stack has an assigned unique Unit ID number. The following sections describe
the Unit IDs and their characteristics.
Chapter 3: Connecting the Switch
Understanding Stack Resiliency
15
Linksys One Ready Communications Solution
Stack Master
The unit assigned the Unit ID number 1 serves as the Stack Master. All other units are stack
members. The Stack Master provides a single point of control, configuration and
management for the entire stack, and stores the configuration for all stack members.
(Members do not store any configuration information.)
Stack Backup Master
The unit assigned the Unit ID number 2 is a special stack member that serves as the stack
Backup Master. A stack Backup Master assumes the role of Stack Master for the remaining
stack members if the stack Master fails or is disconnected.
The Stack Master stores a copy of the active configuration on the Backup Master. This copy is
used only if the Backup Master assumes the role of Stack Master.
NOTE: Only the configuration file is copied. Any
dynamically-filled tables (for example, learned
addresses) are not copied from the Stack Master to the
Backup Master. If the Backup Master assumes the role of
Stack Master, it builds its own dynamic tables.
Stack Members
The units assigned the Unit IDs 3 through 8 are called stack members. A stack member
operates only as a member of the stack under the direction of an operational Stack Master
(or a Backup Master that has assumed the Stack Master role). Stack members are not
directly manageable and configurable, and must be managed through the Stack Master.
They do not contain any meaningful configuration information, including their own
configuration. If an operational Stack Master is not present and reachable, these units are
not functional.
3
Chapter
Master-Enabled Units
Units that are assigned a Unit ID number of 1 or 2 are called master-enabled units. Only
master-enabled units participate in the Master Election process (see below) when they are
initialized, are inserted into a new stack, or lose connectivity with the existing Stack Master.
Only master-enabled units participate in the Master Election process and can become the
Stack Master or Backup Master. (Units that are assigned a Unit ID of 3 through 8 can only
16
Chapter 3: Connecting the Switch
Understanding Advanced Stacking
3
Chapter
Linksys One Ready Communications Solution
become a Stack Master or a Backup Master if they are manually configured by the system
administrator or if they are reset to the factory default mode.)
Unit ID Allocation
Units are shipped from the factory without an assigned Unit ID, and must be assigned a
unique Unit ID before they can operate as part of a stack. Unit ID numbers are assigned to
units in one of two ways:
•Unit ID numbers are assigned by the system administrator, and can be changed only
manually by the system administrator.
•Unit ID numbers are allocated to a stack member unit by the Stack Master during
system initialization.
A unit that was assigned a Unit ID will usually keep this number even after it is rebooted. The
Stack Master may reallocate Unit IDs during system initialization to resolve duplicate Unit ID
conflicts (see below). Manually assigned Unit IDs cannot be changed by the Stack Master,
even if there is a conflict.
Unit ID assignment or change takes effect only during system initialization and does not take
place during system runtime. Units of a stack do not have to be numbered in sequence, and
can be interconnected as long as each unit has a unique ID and at least one unit of the stack
serves as Stack Master.
Stack Unit Startup Process
When a unit in stack mode is initialized (powered up or rebooted), it goes through the
following steps:
1. The Master Discovery and Master Election processes.
2. Unit ID allocation by the Stack Master (including duplicate Unit ID conflict resolution).
3. Unit and port configuration by the Stack Master.
Chapter 3: Connecting the Switch
Understanding Advanced Stacking
17
Linksys One Ready Communications Solution
Master Discovery Process
When a unit in stack mode initializes, its behavior depends on its Unit ID (if one is
configured):
•If the unit does not have a current Unit ID (that is, the unit is in factory default mode)
and if there is a Stack Master, the unit is allocated a Unit ID number from the Stack
Master. If there is no Stack Master, then the unit participates in the Master Election
process, and may be chosen as the new Stack Master or Backup Master.
•If the unit’s current Unit ID is 1 or 2 (that was previously allocated, even if used in a
different stack), then the unit participates in the Master Election process.
•If the unit has a current Unit ID (that was previously allocated, even if used in a
different stack), the unit tries to act according to its Unit ID number in the new stack.
For example, if the unit’s current Unit ID is 3 through 8, it will try to connect to the
running Stack Master, and will not proceed to the next stage until contact with the
Stack Master is made. These units will not participate in the Master Election process,
and if no Stack Master is present, the units are effectively shut down.
The Stack Master and all other stack units carry out a continuous process of Master
Discovery by frequently exchanging stack control messages. This allows units to know if
another unit fails or becomes unreachable.
Master Election Process
3
Chapter
When units in stacking mode initialize, one of the units is elected as the Stack Master. If a
unit in the stack was set to “Force Master” by the system administrator, that unit is elected as
the Stack Master. Only master-enabled stack units (for example, those with the Unit ID of 1
or 2) can be configured as “Force Master.”
If the stack contains units whose unique Unit ID is 1 or 2, then one of these two units will be
the Stack Master. It does not matter if the Unit ID was originally assigned automatically or
manually. These units are called master-enabled units. If there is only one master-enabled
unit, it will be elected as the Stack Master (even if its Unit ID is 2).
If there are two master-enabled units, the two units decide which of them is the Master by
checking which one has been running for a longer time (in intervals of 10 minutes). The unit
that has been running for the longer time will be the Stack Master. If they have been running
for the same amount of time, the unit with the Unit ID of 1 will be the Stack Master. If both
18
Chapter 3: Connecting the Switch
Understanding Advanced Stacking
3
Linksys One Ready Communications Solution
units have been running for the same amount of time and both units have the same Unit ID,
the unit with a lower MAC (hardware) address will be selected as the Stack Master.
If the stack contains one or more units without a current Unit ID (the units are in factory
default mode), then one of these units will be the Stack Master. The unit selected to be the
Stack Master is the one running for the longest time (in intervals of 10 minutes), or, if all units
are running for the same amount of time, the one with the lowest MAC (hardware) address.
Chapter
The Master Election process ensures that the stack has a Stack Master. The Stack Master has
the Unit ID of 1 and the Backup Master, if it exists, has the Unit ID of 2. Alternatively, the
Stack Master has the Unit ID of 2 and the Backup Master, if it exists, has the unit ID of 1.
If a master-enabled unit is added to a stack and powered on, when it comes up it invokes the
Master Election process, even though the rest of the stack already has an elected master.
Because the unit is new, it loses the election and joins as a stack member or Backup Master.
Unit ID Allocation and Duplicate Unit ID Conflict Resolution
After a Stack Master is elected, it allocates Unit IDs to units that do not have a currently
assigned Unit ID (units that are in factory default mode). The Stack Master also attempts to
resolve all cases of units with duplicate Unit IDs. The Stack Master changes the Unit IDs of
units that have a duplicate current Unit ID, provided that there are available, unused Unit
IDs. In a merged stack, if the Stack Master unit remains as the Stack Master, units that were
in its group will keep their unit IDs. Members of other groups are renumbered.
If the conflict occurs after the units reboot, the conflict is resolved as follows:
•If both duplicate units are in auto (self ordering) mode, then the unit ID with the
lower MAC (hardware) address will keep its unit ID. The other unit is assigned a new
unit ID.
•If one of the duplicates is in auto (self ordering) mode, and the other unit is in
manual mode, then the manual mode unit will keep its ID and the other is assigned a
new unit ID.
•If both duplicate units are in manual mode, then both of them are shut down.
If the Stack Master is able to allocate a unique Unit ID to each unit, then all units can operate
as a stack. If the Stack Master is unable to allocate a Unit ID to a unit, that unit is effectively
shut down and will not participate in the stack. For example, units with a conflicting

manually-set Unit ID number are shut down because the Stack Master cannot override the
system administrator’s assignment and resolve the conflict.
Linksys One Ready Communications Solution
3
If there are more units than the maximum number allowed in a stack, and the incoming units
are already in factory default mode (they do not have unit ID assigned), then a Stack Master
is elected following the Master Discovery and Master Election processes. All other units
remain shut down.
Occasionally, due to a race condition during the boot process, some of the units might be
connected and join the stack. If the incoming units already have a unit ID, then none of them
will join the stack and all are left in shutdown mode because there is no way for the Stack
Master to determine their Unit ID preference.
NOTE: If a unit is shut down, its stacking links are
inactive. If the stacking units are connected in a chain
topology, the shutdown of one unit breaks the chain and
can cause other units to be shut down if they have no
active link to the Stack Master unit.
Configuring Units and Ports
After the Master Discovery and Master Election processes, each unit in the stack has a
unique Unit ID, one of the units is the Stack Master, and one of the units may serve as the
Backup Master. The Stack Master then configures each of the member units and its ports
according to the configuration file present on the Stack Master. If the stack has a Backup
Master, the configuration file is copied to the Backup Master.
Chapter
After all the units and ports are configured, the stack enters normal operational mode. If a
change is made to the system configuration, the change is stored by the Stack Master and is
copied to the Backup Master if one exists.
You can use the command-line interface (CLI) or GUI to configure the stack units.

Stack Troubleshooting and Maintenance
Replacing a Failed Member Stack Unit in an Operational Stack
If a unit that is not the Stack Master fails in an operational stack, the Stack Master discovers
that the unit is no longer responding during the Master Discovery process. The Stack Master
directs all other stack members to route unit-to-unit traffic around the failed unit using the
ring topology of the stacking connections. Concurrently, the Stack Master notifies the system
administrator of the failure by sending SYSLOG messages and SNMP traps.
Because all traffic has been routed around the failed unit, when it is disconnected from the
stack, the stack continues to run as long as all other stacking connections are left intact.
When a new unit is inserted in the stack and powered on, the following occurs:
1. The incoming unit, which is in stack mode, performs the Master Discovery process, and
may participate in the Master Election process.
•If the incoming unit has a Unit ID of 1 or 2 (it is a master-enabled unit) it initiates the
Master Election process. However, because the running Stack Master has a longer
runtime, the current Stack Master retains its position and the incoming unit does not
become the new Stack Master.
•If the incoming unit has a Unit ID of 3 through 8, it attempts to become a member
unit of the stack, subject to control by the already running Stack Master, and the
Master Election process does not occur.
3
Chapter
2. The Stack Master performs Unit ID allocation and the conflict resolution process.
•If the incoming unit did not have an assigned Unit ID (that is, it is in factory default
mode), it is assigned the lowest available Unit ID by the Stack Master. We
recommend that you use the automatically-assigned unit ID mode because it
provides better resiliency to the stack.
•If the incoming unit already has an assigned Unit ID, and that Unit ID is unused in
the current stack, the incoming unit keeps its assigned Unit ID and the Stack Master
applies any configuration relevant to that Unit ID to the incoming unit.
•If the incoming unit already has an assigned Unit ID, and that Unit ID conflicts with a
unit ID in the current stack, the Stack Master allocates a new Unit ID to the incoming
unit, giving it the lowest available Unit ID. However, if the incoming unit has a
24

manually assigned Unit ID, the Stack Master cannot change it. If the incoming unit
cannot be assigned an available Unit ID, then it is shut down and is not joined to the
stack.
3. The Stack Master performs unit and port configuration for the incoming unit.
•Any configuration information that is relevant to the number assigned to the
incoming unit is applied by the Stack Master. For example, if the incoming unit is
assigned the same Unit ID of the unit it replaced, then when possible, it receives the
same configuration as the failed unit.
•If the incoming unit is identical to the replaced unit, the entire configuration of the
replaced unit is applied to the incoming unit and the stack returns to the state it was
in before unit failure.
If the incoming unit is not identical to the unit that failed, the Stack Master applies the
configuration in the following manner:
•If a 24-port unit replaces a failed 48-port unit, the ports of the incoming unit are
configured according to the configuration of the first 24 ports of the failed unit.
NOTE: The configuration of all 48 ports of the failed unit
is kept in memory, even though the first 24 are currently
applied. If, in the future, a 48 port unit is inserted and
assigned the same Unit ID, it is configured the same as
the original failed 48-port unit.
•If a 48-port unit replaces a 24-port unit, then the first 24 ports of the incoming unit
are configured according to configuration of the ports of the failed unit. The
remaining ports of the incoming are configured according to the default settings.
•If the units have uplink ports, then the first uplink port of the incoming unit is
configured according to the configuration of the first uplink port of the failed unit.
Replacing a Failed Stack Master Unit in an Operational Stack
When the Stack Master unit fails, the stack Backup Master, using the Master Discovery
process, discovers that the Stack Master unit no longer responds. The Backup Master takes
over as the Stack Master. The Backup Master (now the Stack Master) directs all other stack
members to route unit-to-unit traffic around the failed unit using the ring topology of the

•If the incoming unit has a Unit ID of 1 or 2 (it is a master-enabled unit) it initiates the

longer runtime (if it has been running for more than 10 minutes) it remains the Stack
Master and the incoming unit does not become the new Stack Master. This can cause
an incoming unit with a Unit ID of 1 to serve as the stack Backup Master, while the
current unit with the Unit ID of 2 remains the active Stack Master.
2. The Stack Master performs Unit ID allocation and the conflict resolution process.
•If the incoming unit did not have an assigned Unit ID (that is, it is in factory default

Chapter
Splitting a Stack
A working stack can be split into two groups, either by failure of a stacking link connecting
two units in the stack, or by a failed unit in a chain topology that causes disconnection
between two units in the stack. In this case, each group is considered as an independent
running stack configuration. For each group, there are three scenarios.
The Stack Master and Backup Master Units Remain in a Group
In this scenario, the Stack Master routes around the missing units. The Master Discovery,
Master Election and Unit ID Allocation & Duplicate Unit ID Conflict Resolution processes
occur with the following results:
•Any configuration information contained in the Stack Master that is relevant to the units
which remained in the split group remains unchanged.
•Topology information (the information for each unit on how to send traffic to any other
unit in the stack) managed by the Stack Master includes only units that are reachable
(connected) following the split.
•The split stack continues to work as it previously did, but with fewer units.
-No unit ID changes are performed in each of the split stacks.
-The Stack Master notifies the system administrator of the removed units and ports
that belong to the unreachable units by sending SYSLOG messages and SNMP
traps. They are reported as “not present.”
The Stack Master or the Backup Master Unit Remains in a Group
If the Stack Master unit remains in the group, the scenario described in “Replacing a Failed
Member Stack Unit in an Operational Stack” applies. If the Backup Master unit remains in

the group, the scenario described in “Replacing a Failed Stack Master Unit in an
Operational Stack” applies.
Linksys One Ready Communications Solution
3
NOTE: If the stack is split in two groups, one with the
Stack Master and one with the Backup Master, both
groups will function.
The Master Discovery, Master Election and Unit ID Allocation & Duplicate Unit ID Conflict
Resolution processes occur with the following results:
•If the Stack Master unit remains in the split stack, the Stack Master discovers (using
the Master Discovery process) that the Master Backup unit no longer responds. The
Stack Master notifies the system administrator (using SYSLOG messages and SNMP
traps) of the removed units and ports that belong to the unreachable units and they
are reported as “not present.”
•If the Backup Master unit remains in the split stack, the Backup Master determines
this as a case of Stack Master failure and takes over and manages the remaining
units as a stack while keeping its previous Unit ID number. Because the Backup
Master was not acting as a master prior to the split, it initiates a topology database
and ports learning process. Traffic might be halted for a short period of time until
synchronization (unit and port configuration) is completed. New units discovered by
the Backup Master notify the system administrator (using SYSLOG messages and
SNMP traps).
•The partial stacks both continue to work as they did previously, but with fewer units.
Chapter
•No unit ID changes are performed in each of the partial stacks.
•If each part of the stack has a Stack Master (for example, one contains the original
Stack Master, and one contains the Backup Master), and are operating as two
separate stacks, both Stack Masters contain the same configuration and use the
same IP address.
NOTE: If both Stack Masters use the same IP Address,
problems can occur on the network, because users
cannot connect to one of the stacks through its IP address.
28

Chapter
Neither the Stack Master Unit or the Backup Master Unit Remains in the Group
This scenario is the same as that of a failed Stack Master where no Backup Master is
available. The following concepts apply:
•Units whose ID numbers are 3 through 8 in this part of the original stack will not
renumber themselves, and will remain shut down until a master-enabled unit is
connected and begins to operate as the Stack Master. The Master Discovery process
discovers that the Stack Master has failed.
•In this group, the units lose connection with the Stack Master. Since they began as a
running stack and none of them are in factory default mode, renumbering does not
occur, and even a reset of the units will not affect unit ID assignment, because units
can be renumbered only by a Stack Master.
•No unit ID changes are performed in each one of the two groups.
NOTE: None of the units in either group will renumber
themselves.
Merging Two Stacks
To merge two working stacks and create one stack, first decide if you will merge the stacks
while the incoming units are powered off during insertion, or if both stacks will be running
when merged.
If the incoming units are powered off, follow the procedures described in “Building a New
Stack” in the “Building Automatically-Configured Stacks” or “Building Manually-Configured
Stacks” sections. Repeat the process for each unit inserted into the stack.
If both stacks to be merged are running (for example, you are connecting the stacking cables
of two stacks), the following occurs:
•If each of the joined stacks has a Stack Master unit, both Stack Master units perform the
Master Discovery process and participate in the Master Election process. One of the
Stack Master units is selected as the Stack Master unit for the merged stack. The criteria
for choosing the Stack Master are as follows:
Chapter 3: Connecting the Switch
Stack Troubleshooting and Maintenance
29
-Force Master: If Force Master is enabled, the unit that is configured as the forced
unit is selected as the Stack Master.
Linksys One Ready Communications Solution
3
-System Up Time: Up time is measured by quantities of 10-minute intervals. If the
number of 10 minute intervals is higher for one of the units, this unit is selected
as the Stack Master.
-Lowest Unit ID: If both units have the same up time (measured in intervals of 10
minutes), the unit with the lowest unit ID is selected as the Stack Master.
-Lowest MAC: If both Master unit ID numbers are equal, the unit with the Lower
MAC address is chosen as the Stack Master.
The Stack Master unit that loses its “mastership” in the Master Election process is
renumbered if the unit ID was dynamically allocated. The new Stack Master allocates it a
new number and configures it as a stack member or a Backup Master. It will be shut
down if the unit ID was manually allocated. We recommend that the administrator
configure the unit to receive an auto-assigned Unit ID before reconnecting it to the stack.
NOTE: There will never be two units with the same Unit ID
at the end of the merge.
When two stacks are combined, all of the configuration information for one of the stacks
is lost. Only the surviving Stack Master (after the discovery and election processes are
complete) maintains its configuration information.
Chapter
We recommend that when combining two stacks, you reset the switches in one stack to
factory default mode and then add the switches as described in “Adding Units to a
Running Stack” in the “Building Automatically-Configured Stacks” section.
•If one of the merged stacks had neither a Stack Master unit nor a Backup Master unit,
then units belonging to this group are inserted into the stack as described in “Replacing
30
Chapter 3: Connecting the Switch
Stack Troubleshooting and Maintenance
3
Chapter

a Failed Member Stack Unit in an Operational Stack.” The Master either connects the
running units to the stack using the current Unit ID numbers or renumbers them.
NOTE: Any time two stacks are combined into one stack,
there is no way to maintain the configuration for both sets
of switches. All dynamic information of the units that
belong to the portion of the stack that was not re-elected
to be the Stack Master is relearned.
Understanding Stacking Cable Failure
If the stacking connection cables fail and cause a stack split, the scenario described in
“Merging Two Stacks” applies. This occurs only if the stack uses a chain topology. Single
stacking cable failure will not cause a stack split if a ring topology is used.
Inserting Too Many Units into a Stack
If you try to insert too many units into a stack, when all units (existing and newly inserted)
are powered on at the same time, the following occurs:
1. A Stack Master is elected following the Master Discovery and Master Election processes.
All other units are shut down.
NOTE: Occasionally, due to a race condition during the
boot process, some of the units might be connected and
join the stack.
When a running group of units is added to an existing stack and each one of the stack
groups has an elected Stack Master, and the total of existing units and inserted units exceeds
the maximum allowed number of units (8) in a stack:
•The Master Detection and Master Election processes determine the Stack Master out
of one of the two combined stacking groups.
•When switches are added to a running stack, the Unit ID Allocation and Duplicate
ID conflict resolution processes detect an error if too many switches are present in the
stack, and no changes are made to units that originally belonged to the group
Chapter 3: Connecting the Switch
Stack Troubleshooting and Maintenance
31
managed by the newly-elected Stack Master. The original switches retain their ID
assignments and configurations. The units that originally belonged to the group
managed by the Stack Master that lost its “mastership” are shut down.
Inserting a Standalone Unit into a Running Stack
If a unit is in standalone mode, it will not participate in the Master Discovery process (it will
not look for a Stack Master and will not respond to master queries). As a result, it will not
join the stack but will continue to run as a standalone unit. The ports that are connected to
the other units’ stacking links will not pass any traffic, and the Stack Master will consider
them as failed stacking links and route all traffic around them.

Web Utility Configuration
Overview
The Linksys Switch provides a complete web-based utility to configure the Ethernet switch.
This utility is accessible through your web browser.
Use the navigation window, located on the left side of the web-based utility, to view various
functions of the Ethernet switch.
NOTE: The Ethernet switch is setup by
default to obtain its IP address via DHCP
on the default VLAN 100.
Accessing the Web-based Utility
To access the web-based utility, enter the IP address of the Ethernet switch to the address field
of your web browser. For example: type http://192.168.100.20 or
https://192.168.100.20 if the IP address of the Ethernet switch is 192.168.100.20. The IP
address of the Ethernet switch is determined by DHCP, so you’ll need to find its address using
the Console configuration or the Linksys One Administrator screen.

Chapter
If your Ethernet switch is part of a Linksys One system, the easiest way to manage it is with
the Linksys One Portal — available only on the Linksys One Services Router. Refer to the
Customer Premises Equipment Administration Guide for more details on the Linksys One
Portal.
