General Stacking Guidelines
Here are additional stacking guidelines:

Stacking is enabled by default on x930 Switches.

VCStack comes standard with the AlliedWare Plus software for
x930 Switches. No additional software or licenses are required.

The switches must all have the same version of AlliedWare Plus
software.

The switches can be the same or different x930 models.

Any x930 Switch can be the master switch of a stack.

A stack of x930 Switches cannot contain other stacking switches,
such as x600 or x610 Switches.

In stacks of three or more switches, all the switches must have the
same number of trunk ports.

Do not configure switch features, such as virtual LANs and routing
protocols, before building the stack. Switches might discard the
settings when the stack is powered on for the first time.

Trunk ports must be directly linked together. There cannot be any
intermediary devices, such as media converters, routers, or other
switches, between trunk ports.

Trunks cannot have different types of trunk ports. For example, a
trunk cannot have both Gigabit copper ports and ports S1 and S2.
