Stacking Guidelines
Here are the stacking guidelines:
The stack can have two switches.
The switches of the stack must be the same model. The stack can
have two AT-SBx8112 chassis or two AT-SBx8106 chassis. A
stack cannot have one AT-SBx8112 chassis and one AT-SBx8106
chassis.
The trunk that connects the two switches of the stack are built with
AT-StackOP/0.3 or AT-StackOP/9.0 stacking transceivers in the
SFP+ slots in the controller cards.
There cannot be any network devices, such as other switches or
media converters, between the stacking transceivers in the two
switches.
The bandwidth of the trunk depends on the number of controller
cards and stacking transceivers in the switches. The trunk has a
bandwidth of 40 Gbps when each switch has one controller card,
and 80 Gbps when each switch has two controller cards, For more
information, refer to “Stack Trunk and Stacking Transceivers” on
page 271.
The SFP+ slots on the controller cards support the stacking
transceivers only when stacking is enabled on the switch. Standard
SFP+ transceivers are not supported in the SFP+ slots when
stacking is enabled.
When stacking is disabled, the SFP+ slots can be used with
standard SFP+ transceivers, but not with stacking transceivers.
The default setting for stacking is disabled.
The switches have to be assigned ID numbers. The numbers are 1
and 2. The switches must be assigned different numbers. For more
information, refer to “Chassis ID Numbers” on page 278.
A stack should not have more than 400 Ethernet ports.
If both switches of the stack have two controller cards, the SFP+
slots on both the active master and inactive master controller cards
are active in linking the units together and forwarding traffic.
The two switches of the stack must have the same OEM territory
and feature licenses.
The two switches of a stack do not share the AlliedWare Plus
operating system.
