Overview

This chapter contains the following sections:

 “AT-8000GS Switch Series Features” on page 10

 “IEEE Standards” on page 11

 “Model Descriptions” on page 12

 “Port Descriptions” on page 15

 “LED Definitions” on page 16

The AT-8000GS Gigabit Ethernet Switch series includes three device
models, which consist of the following hardware configurations:

 AT-8000GS/24 Gigabit Ethernet Switch with 24 10/100/1000 Base-T

ports with 4 1000Base-X SFP combo ports and 2 HDMI interface
stacking ports.

 AT-8000GS/24POE Gigabit Ethernet Switch with 24 10/100/1000

Base-T ports ports with modular configuration 4 x 1000Base-X SFP
Combo ports and 2 HDMI interface stacking ports and support for

802.3af Power over Ethernet on the RJ-45 ports. The total POE power
available is 140W which allows for a maximum of nine class 3 devices
(15.4W per device) or a dynamic distribution of power across any or all
24 ports based on user-assigned priorities.

 AT-8000GS/24POE Gigabit Ethernet Switch with 48 10/100/1000

Base-T ports with modular configuration 4 x combo 1000Base-X SFP
Combo ports and 2 HDMI interface stacking ports.

All the platforms can operate as standalone systems, or can be stacked
together in the same system. A stack of six units maximum is supported.

In each stack, at any given point of time, there is a single Stack unit that is
the stack’s “Master”; all other units are “Slaves”. One of the slaves can act
as a backup master, so that in the event of failure of the master unit, the
backup takes over. The Stack architecture provides for dynamic learning
of the topology, and dynamic detection at stack start-up.

Device configuration is performed through an Embedded Web Server
(EWS) or through a Command Line interface (CLI). The device
management is performed through an RS-232 interface.

Stacking

This section describes the stacking control management and includes the
following topics:

 “Stacking Overview” on page 36

 “Configuring Stacking” on page 40

35

Chapter 3: Stacking

Stacking Overview

Stacking provides multiple switch management through a single point as if
all stack members are a single unit. All stack members are accessed
through a single IP address through which the stack is managed. The
stack can be managed using the following interfaces:

 Web-based Interface

 SNMP Management Station

 Command Line Interface (CLI)

Devices support stacking up to six units per stack, or can operate as
stand-alone units. During the Stacking setup, one switch is selected as the
Stacking Master and another stacking member can be selected as the
Secondary Master. All other devices are selected as stack members, and
assigned a unique Unit ID.

Switch software is downloaded separately for each stack member.
However, all units in the stack must be running the same software version.

Stacking Ring

Topology

Switch stacking and configuration is maintained by the Stacking Master.
The Stacking Master detects and reconfigures the ports with minimal
operational impact in the event of:

 Unit Failure

 Inter-unit Stacking Link Failure

 Unit Insertion

 Removing a Stacking Unit

 This section includes the following topics:

 “Stacking Ring Topology,” next

 “Stacking Chain Topology,” next

 “Stacking Members and Unit ID,” next

 “Removing and Replacing Stacking Members,” next

 “Exchanging Stacking Members,” next

Stacked devices operate in a Ring topology. A Ring topology is where all
devices in the stack are connected to each other forming a circle. Each
stacked device accepts data and sends it to the device to which it is
physically connected. The packet continues through the stack until it
reaches the destination port. The system automatically discovers the
optimal path on which to send traffic.

36

Most difficulties in Ring topologies occur when a device in the ring
becomes non-functional, or a link is severed. In a stack, the system

AT-8000GS Series Gigabit Ethernet Switch Installation Guide

automatically switches to a Stacking Failover topology without any system
downtime. An SNMP message is automatically generated, but no stack
management action is required. However, the stacking link or stacking
member must be repaired to ensure the stacking integrity.

After the stacking issues are resolved, the device can be reconnected to
the stack without interruption, and the Ring topology is restored.

Stacking Chain

Topology

Stacking

Members and

Unit ID

In a chain topology, there are two units that have only one neighbor. Every
unit has an uplink neighbor and a downlink neighbor. The chain topology is
less robust than the ring topology. A failure in the chain results in a
topology change to the stack. The location of the failure determines the
severity of this topology change. The chain topology also acts as a fail­safe for the ring topology. When the ring topology fails, the stack
automatically reverts to the chain topology.

Stacking Unit IDs are essential to the stacking configuration. The stacking
operation is determined during the boot process. The Operation Mode is
determined by the Unit ID selected during the initialization process. For
example, if the user selected stand-alone mode, the device boots as a
stand-alone device.

The device units are shipped with the default Unit ID of the stand-alone
unit. If the device is operating as a stand-alone unit, all stacking LEDs are
off. Once the user selects a different Unit ID, the default Unit ID is not
erased, and remains valid, even if the unit is reset.

Unit ID 1 and Unit ID 2 are reserved for Master-enabled units. Unit IDs 3 to
6 can be defined for stack members.

When the Stacking Master unit boots, or when inserting or removing a
stack member, the Stacking Master initiates a stacking discovering
process.

Removing and

Replacing

Stacking

Members

If two members are discovered with the same Unit ID, the stack continues
to function, however only the unit with the older join time joins the stack. A
message is sent to the user, notifying that a unit failed to join the stack.

For first time Unit ID assignment, see the Installation Guide.

Stacking member 1 and stacking member 2 are Master-enabled units. Unit
1 and Unit 2 are either designated as Stacking Master or Secondary
Master. The Stacking Master assignment is performed during the
configuration process. One Master-enabled stack member is elected
Stacking Master, and the other Master-enabled stack member is elected
Secondary Master, according to the following decision process:

If only one Master-enabled unit is present, it is elected Stacking Master.

If two Master-enabled stacking members are present, and one has been

37

Chapter 3: Stacking

manually configured as the Stacking Master, the manually configured
member is elected Stacking Master.

If two Master-enabled units are present and neither has been manually
configured as the Stacking Master, the one with the longer up-time is
elected Stacking Master.

If the two Master-enabled stacking members are the same age, Unit 1 is
elected Stacking Master.

Two stacking member are considered the same age if they were inserted
within the same ten minute interval.

For example, if Stack member 2 is inserted in the first minute of a ten­minute cycle, and Stack member 1 is inserted in fifth minute of the same
cycle, the units are considered the same age. If there are two Master­enabled units that are the same age, then Unit 1 is elected Stacking
Master.

The Stacking Master and the Secondary Master maintain a Warm
Standby. The Warm Standby ensures that the Secondary Master takes
over for the Stacking Master if a failover occurs. This guarantees that the
stack continues to operate normally.

During the Warm Standby, the Master and the Secondary Master are
synchronized with the static configuration only. When the Stacking Master
is configured, the Stacking Master must synchronize the Secondary
Master. The Dynamic configuration is not saved, for example, dynamically
learned MAC addresses are not saved.

Each port in the stack has a specific Unit ID, port type, and port number,
which are part of both the configuration commands and the configuration
files. Configuration files are managed only from the device Stacking
Master, including:

 Saving to the Flash

 Uploading configuration files to an external TFTP Server

 Downloading configuration files from an external TFTP Server

Whenever a reboot occurs, topology discovery is performed, and the
Master learns all units in the stack. Unit IDs are saved in the unit and are
learned through topology discovery. If a unit attempts to boot without a
selected Master, and the unit is not operating in stand-alone mode, the
unit does not boot.

Configuration files are changed only through explicit user configuration.
Configuration files are not automatically modified when:

38

 Units are added

 Units are removed

AT-8000GS Series Gigabit Ethernet Switch Installation Guide

 Units are reassigned Unit IDs

 Units toggle between Stacking mode and Stand-alone mode

Each time the system reboots, the Startup configuration file in the Master
unit is used to configure the stack. If a stack member is removed from the
stack and then replaced with a unit with the same Unit ID, the stack
member is configured with the original device configuration. Only ports
which are physically present are displayed in the Web Management
Interface home page, and can be configured through the web
management system. Non-present ports are configured through the CLI or
SNMP interfaces.

Exchanging

Stacking

Members

If a stack member with the same Unit ID replaces an existing Unit ID with
the same Unit ID, the previous device configuration is applied to the
inserted stack member. If the new inserted device has either more ports or
less ports than the previous device, the relevant port configuration is
applied to the new stack member.

The Secondary Master replaces the Stacking Master if the following
events occur:

 The Stacking Master fails or is removed from the stack.

 Links from the Stacking Master to the stacking members fails.

 A soft switchover is performed via the web interface or the CLI.

Switching between the Stacking Master and the Secondary Master results
in a limited service loss. Any dynamic tables are relearned if a failure
occurs. The Running Configuration file is synchronized between the
Stacking Master and the Secondary Master, and continues running on the
Secondary Master.

39

Chapter 3: Stacking

Configuring Stacking

Configuring stacking is performed during the bootup process. To configure
a device as part of a stack, the bootup process must be interrupted
straight after the Power On Self Test (POST).

To configure the device for stacking, perform the following:

1. Ensure that the device console is connected to a VT100 terminal device or VT100

2. Deactivate the AC power receptacle.

3. Connect the device to the AC receptacle.

4. Activate the AC power receptacle.

terminal emulator.

When the power is turned on with the local terminal already connected, the switch
goes through POST. POST runs every time the device is initialized and checks
hardware components to determine if the device is fully operational before completely
booting. If a critical problem is detected, the program flow stops. If POST passes
successfully, a valid executable image is loaded into RAM. POST messages are
displayed on the terminal and indicate test success or failure.

As the switch boots, the bootup test first counts the device memory availability and
then continues to boot. The following screen is an example of the displayed POST.

Note

AT-8000GS Series Gigabit Ethernet Switch Installation Guide

The initial configuration, which starts after the device has booted
successfully, includes static IP address and subnet mask configuration,
and setting user name and privilege level to allow remote management. If
the device is to be managed from an SNMP-based management station,
SNMP community strings must also be configured. The following
configurations are completed:

 Static IP Address and Subnet Mask

 User Name

Static IP Address

and Subnet Mask

IP interfaces can be configured on each port of the device. After entering
the configuration command, it is recommended to check if a port was
configured with the IP address by entering the “show ip interface”
command.

The commands to configure the device are port specific.

To manage the switch from a remote network, a default gateway must be
configured, which is an IP address to where packets are sent when the
destination is within another network. The configured gateway address
must belong to the same subnet as the IP interface of the device.

To configure the default gateway, enter the required commands at the
system prompt as shown in the following configuration example where

101.101.101.101 is the specific management station, and 100.1.1.254 is

the default gateway:

console#

console# configure

console(config-if)# exit

console(config)# ip default-gateway 100.1.1.254

console(config)# exit

100.1.1.254 is the IP address of the default gateway that is used to
reach the management network 101.101.0.0.

To check the configuration, enter the command “show ip interface” as
