1. What is Stack?
1.1

Overview of Stackable Switches

A typical technique for layer 2 redundancy is to use a "protocol" such as STP. However, themechanism of STP is complex and unstable as well as prone to loop faults and other problems.
Therefore, a new mainstream technique has come out to provide "stack functionality"-based
redundancy, which does not depend on any protocols. This technique provides simple and reliable
redundancy, as it allows multiple switches to be managed as a single switch, causing no loop fault. A
switch that supports stack functionality is called a "stackable switch".
The “stackable switch” allows the consolidated management of switches by virtually managing
multiple switches as a single switch. This consolidates the management of information including IPs,
configurations, and MIBs (management information bases), making it easier to check connection
status, detect problems and reduce the burden on the operator.

AX2600S Series Stack Installation Guide (Edition 1)(2) Use cases《 for floor switches and distribution switches 》【Use case 1】 Floor switch
As a floor switch, the AX2600S allows flexible port increase. When you need a large
port capacity, you can increase the number of ports by stacking switches.
【Use case 2】 Distribution switch
As a distribution switch, the AX2600S realizes STP-free simple redundancy. Unlike theunstable STP in the past, redundancy by link aggregation realizes a loop-free network
logically, allowing you to use all links effectively (low-cost and high-quality redundancy).

(3) Advanced high-quality network realized by L2 stack functionality《 non-stop simple system adaptable to a variety of uses 》
Flexible redundancy of your choice
You can configure a full link aggregation network by using L2 stack in a simple
redundant network. This enhances the flexibility of network redundancy adapting toeach user’s needs.

2. Stack Overview
2.1

Stack Components

This section explains the stack components and the stack terminology used in this document.
A stack consists of two member switches—one master switch and one backup switch. The master switch
controls the other member switch, and they run virtually as a single switch.
In the stack configuration, ports for connecting the member switches (a master switch and a backup
switch) are called "stack ports", and the lines connected to the ports are called "stack links."
A switch number is a number for identifying a member switch composing the stack and is unique to eachmember switch. In a stack configuration, to secure line redundancy, link aggregation is establishedbetween the upper-level and lower-level switches across the member switches.

Introduction to Stack Stack specifications
ALAXALA’s stack is configured by connecting member switches via a general-purpose Ethernet
line or a direct attach cable. No special cable is necessary for stacking. A stack can consist of up
to two switches (different models can be used).

23Models available for stacking

All models of the AX2600S Series (different switch
models of the same series can be used together) Stack ports
Stack ports are ports connecting member switches that make up a stack, and up to two ports
can be used per member switch.
Use the SFP/SFP+ shared ports as stack ports. Of these ports, the ports numbered
29 and 30 can be used as stack ports for the 24-port models, and those numbered
53 and 54 can be used for the 48-port models. To use the SFP/SFP+ shared ports as
10G interfaces, purchase a 10G up-link option license (OP-ULTG).

 Stack link
Stack links are lines connecting the stack ports of the two member switches. Up to two stacklinks can be used. Establish stack links by directly connecting them to the ports using Ethernet
lines. Do not set any other network devices between the two member switches.

Overview of Stack Behavior(1) Master switch role
The master switch controls all member switches of a stack and their functionality. Each member
switch behaves according to the configuration in and control from the master switch.
The master switch represents the member switches. If the user logs in from a remote terminal, theuser is always logged into the master switch. The user can perform the following operations from themaster switch in which the user is logged:
 Editing and viewing configurations
 Operating all member switches Viewing operation messages and logs of all member switches

However, if its master selection priority is 1 and the other member
switch has a master selection priority of 2 or higher, the latter isselected as the master.
The backup switch is selected as the master.
This case occurs if the master switch goes down due to a fault orother problem.
A member switch with the highest master selection priority is
selected as the master. If both are set to the same priority, amember switch with the lowest device MAC address is selected
as the master.
This case occurs if two member switches are started at the sametime.
A member switch with the highest master selection priority is
selected as the master. If both are set to the same priority, amember switch with the lowest device MAC address is selected
as the master.
This case occurs if two stacks that are both a one-member switch
stack are connected.

9AX2600S Series Stack Installation Guide (Edition 1)(3) Packet forwarding in a stack configuration
To use line redundancy in a stack, it is recommended you use link aggregation across themember switches so that forwarding can be continued even if a fault occurs.
In an ALAXALA stack, if forwarding paths are set to be redundant using link aggregation acrossthe two member switches (see the figure below), packets are forwarded to the port of the member
switch which received a packet first. If no fault occurs, packets are forwarded using the shortest path
without going through the stack links.
No data passes

no fault occurs.

Overview of Stack Behavior During Fault

This section describes how a stack behaves if a fault occurs in (1) the master switch, (2) a line, and (3)a stack link, in this order.

(1) Behavior if a fault occurs in the master switch
If the master switch stops due to a fault in it, the backup switch becomes the master and the stack
continues to run. At the same time, communications going through the old master switch are now
redirected to go through the new master switch. If the backup switch stops due to a fault in it, the stack
status does not change and only communications going through the backup switch are now redirected
to go through the master switch.

AX2600S Series Stack Installation Guide (Edition 1)(2) Behavior if a line fault occurs
If a fault occurs in a line of link aggregation across the member switches, either of the following two
behaviors (see below figures) occurs. In either case, the faulty line is bypassed and the linkaggregation continues to operate in degraded mode. In this case, the stack status does not change
and only the communication path changes.

(3) Behavior if a stack link fault occurs
If all stack links fail, it becomes impossible for the master switch and backup switch to recognize
one another. As a result, one stack is divided into two stacks, where the master switch remains themaster and the backup switch becomes a new master. The system enters a dual master state.
In this state, since the two stacks use the same IP address and the same device MAC address, you
may not be able to use the following functions due to a duplicate address.
 Remote login (telnet)
 SNMP, MIB/Trap
 Output to a syslog server
 IP communication (i.e., ping) Authentication functionality
If such a dual master state occurs, stop either of the member switches.
To avoid such a dual master state, configure a stack with two stack links so that the stack cancontinue to work even if one of its links is disconnected due to a fault. In this case, the stack status
and communication paths do not change.

3. Stack Setup
This chapter provides some tips on setting up a system with a stack and how to set up such a system.

3.1

Applying L2 stack to the distribution switches

Below is a setup example of the AX2600S Series stack. This example shows an ALAXALArecommended fault-tolerant network, assuming a large capacity network for big companies.
In this example, AX3660S switches are stacked (L3 stack) as a core switch, and AX2600S
switches are stacked (L2 stack) as a server or distribution switch. 10G interfaces are used
between the server switch and the core switch and between the core switch and the
distribution switch. 1G interfaces are used between the distribution switch and each floor
switch. In each section, line redundancy is established by using link aggregation acrossstack member switches.

The table below shows the switch models and modules used in this example with required minimum
quantities (not including PS, FAN, optical or UTP cables).

System configuration diagram

In the diagram below, you can see the physical connections and logical configurations used in the
setup example. Also, the diagram shows how to configure a core switch (Core), a server switch (SV),distribution switches (DSx) and floor switches (FLx). For the setup of distribution switches (DSx) andfloor switches (FLx), only the description for DS1 and FL1 and FL2 is given (setup for DS2, FL3 and FL4is the same as for DS1, FL1 and FL2).

3.1.2

Configuration tips

The configuration tips for this setup example are as follows:(1) Do not use a Spanning Tree Protocol in a stack.
(2) Use two ports for stack link redundancy.
(3) Use a long-distance transceiver when stacking the switches distanced from each other.
(4) Establish a stack link by directly connecting the member switches to each other.
(5) Deploy a stack to the system after completing the stack settings.
(6) Make a backup of device information for a stack.
Details are as follows.

(1)

Do not use a Spanning Tree Protocol in a stack.

A network system with a stack uses link aggregation for line redundancy, thus it does not use aSpanning Tree Protocol.
If stack functionality is enabled in the AX2600S Series, disable the Spanning Tree Protocol, including
for the upper-level switch (server switch) and the lower-level switch (floor switch).

14

AX2600S Series Stack Installation Guide (Edition 1)(2)

Use two ports for stack link redundancy.

If there is only one stack link and it fails, it becomes impossible for the master switch and backup
switch to recognize each other, due to which you may not be able to use IP communication andauthentications (i.e., telnet、SNMP、MIB/Trap, output to Syslog servers, ping).
To avoid this, configure two ports as stack ports for stack link redundancy.
Up to two ports can be used as stack ports.

(3)

Use a long-distance transceiver when stacking switches located in each different places.

Select the appropriate type of cables according to the actual installation and purpose. If the
distance between the member switches is short (e.g., being installed in the same rack), use a lowcost direct-attach cable for a stack link.
On the other hand, if you connect the member switches located in each different buildings, use along- distance optical transceiver so that you can configure a stack remotely.

(4)

Establish a stack link by directly connecting the member switches to each other.

Establish a stack link by directly connecting the member switches to each other using a line (direct
attach cable, optical cable, or UTP cable). Do not set any other network devices (i.e., Layer 2 switches,
hubs, or media converters) between the member switches (doing this may disable stack operation).

(5)

Deploy a stack to the system after completing the stack settings.

To set up a system with a stack, make two standalone switches into a two-switch stack, configure thenecessary settings, and then connect the member switches via physical line cables. An overview ofthe procedure is given below.

Step ３Connect physical lines and deploy the stack to the system.

Make a backup of device information for a stack.

The AX Series has backup-and-restore functionality. In a stack configuration, the backup and restore
functionality eliminates the task of software version matching and configuration settings, easing the
replacement of a switch in the event of hardware failure.
Therefore, when using a stack, use the backup functionality so that you can save a backup file ofdevice information to each member switch beforehand.

Setup tips

The setup tips for this configuration example are as follows.

(1) Make standalone switches into a stack.
(2) Stack redundancy does not need link aggregation.
(3) Set line redundancy by configuring link aggregation across the member switches.
(4) Disable the Spanning Tree Protocol.
(5) Optimize the link-down detection time.

(1)

Make standalone switches into a stack.

AX2630S

The configuration tips for making a stack from the standalone switches are as follows. Note that theconfiguration setting is different between the master and the backup member switch.

MasterBackup《 Step ① ： Confirm the software version. 》
Confirm the software versions of the stack member switches. If the software versions are different,
perform software update to make them the same.
MasterCopyright © 2023, ALAXALA Networks Corporation. All rights reserved.

Backup17

AX2600S Series Stack Installation Guide (Edition 1)《 Step ② ： Set the option license. 》
Set the stack license (OP-STK) for the two stack member switches. In addition, you can installthe 10G up-link license (OP-ULTG) if necessary. After setting the license, reboot the switches toenable the license.
Master《 Step ③ ： Enable the stack functionality of member switch A. 》
To activate stack member switch A, disable Zero Touch Provisioning, and then enable the stackand set Switch number: 1 by using the operation command (set command). After completing allthese settings, reboot the device to enable the stack.
Master《 Step ④ ： Set config for all member switches in member switch A.》
The configuration of the backup switch is synchronized with that of the master switch. Therefore,
configure all necessary stack settings (stack ports, switch model, and master selection priority for
all member switches) in the master switch. To make member switch A the master switch, set themaster selection priority of member switch A to a value greater than that of member switch B.

Backup《Step ⑤ ： Enable the stack functionality of member switch B.》
To activate stack member switch B, disable Zero Touch Provisioning, and then enable the stackand set Switch number: 2 by using the operation command (set command). After completing allthese settings, reboot the device to enable the stack.
Backup《Step ⑥ ： On member switch B, set its stack port and priority.》
On stack member switch B, set its own items required to be a stack member (stack port, masterselection priority). To make member switch B the backup switch, set its master selection priority toa value smaller than that of member switch A. The configuration set on switch B will be replacedwith the configuration of member switch A (master switch) after the stack ports are connected.
MasterBackup《 Step ⑦ ： Connect the stack ports of the switches to make a two-switch stack.》
Finally, after completing the above settings, establish a stack link between member switches A
and B by connecting their stack ports. After this, a two-switch stack will be established, allowing
member switch B (backup) to run in sync with the configuration of member switch A (master).

(2)

Stack redundancy does not need link aggregation.

AX2630S

Stack link redundancy can be achieved simply by specifying two stack ports and connecting cables
to them, without being aware of link aggregation settings.

(3)

Set line redundancy by configuring link aggregation across the member switches.

AX2630S

To achieve line redundancy, configure link aggregation between the ports of the master switch (switch
No. 1) and the backup switch (switch No. 2).

(4)

Disable the Spanning Tree Protocol.

AX2630S

Other devices

Disable the Spanning Tree Protocol for all switches because it is not used in the stack network system.
In the AX2600S Series, the Spanning Tree Protocol cannot be disabled just by rebooting the switch
after enabling the stack functionality. You need to set the Spanning Tree Protocol to the disabling
mode.

(5)

Optimize the link-down detection time.

AX2630S

Other devices

Set the link-down detection time (link debounce time) value as low as possible without rendering alink unstable. This shortens the time of the degraded operation of link aggregation in case of a failure.

Applying L2 Stack to the floor switches

The configuration example for applying the AX2600S Series stack to the floor switches
is shown below. This example assumes a small capacity network for medium and small-scalecompanies.
In this example, AX3660S switches are stacked (L3 stack) as a core switch, and AX2600S
switches are stacked (L2 stack) as a server or distribution switch. 10G interfaces are used
between the server switch and the core switch. 1G interfaces are used between the coreswitch and each floor switch. In each section, line redundancy is established by using linkaggregation across stack member switches.

The table below shows the switch models and modules used in this example with required minimum
quantities (not including PS, FAN, optical or UTP cables).

System configuration diagram

In the diagram below, you can see the physical connections and logical configurations used in the
setup example. Also, the diagram shows how to configure a core switch (Core), a server switch (SV),and floor switches (FLx). For the setup of floor switches (FL2), follow the steps described for FL1.

The configuration/setting tips in L2 stack here are the same as the tips described in
3.1.2 Configuration tips and 3.1.3 Setup tips, except for the floor switches. Note thefollowing configuration tips when applying L2 stack to the floor switches.

3.2.2

Configuration tips

The configuration tips for this setup example are as follows.

(1)

Possible to use different device models as the stack member switches.

In an AX2600S stack, you can use different device models as the stack members if
you have licenses. Select appropriate models based on the floor switches capacity ofaccommodating terminal devices, required bandwidth of stack links/up-links, and so on.

To edit a configuration, be sure to use the master switch. When editing a configuration from the
backup switch, connect to the master switch beforehand by the operation command session.

(2) Device login
When you connect to the system remotely, be sure to log into the master switch. When you log into
the master or backup switch via console, the following command prompt is displayed.

◆ Logging into the master switch
