Here are the main points of stacking:
ˆ The AT-9400 Gigabit Ethernet Switches operate as a single, logical
unit where functions such as port trunks and port mirrors, can span all
of the devices in the stack.
ˆ The switches are managed as a unit.
ˆ The switches share a common MAC address table.
ˆ The switches must be installed in the same wiring closet in the same
equipment rack.
ˆ The switches are cabled together with the AT-StackXG Stacking
Module.
ˆ This stack feature is only supported on the AT-9424Ts, AT-9424Ts/XP,
and AT-9448Ts/XP Switches.
For more information on stacking, refer to Chapter 1, Overview in the
AT-S63 Stack Command Line Interface User’s Guide.
