Choosing Static or Dynamic Module ID Numbers
The switches of a stack are identified by module ID numbers. The range is
1 to 5 for a stack of 48-port AT-9448Ts/XP Switches and 1 to 8 for a stack
of 24-port AT-9424Ts or AT-9424Ts/XP Switches, or both 24-port and 48-
port switches. The ranges correspond to the maximum number of switches
permitted in a stack, as explained in “Maximum Number of Switches in a
Stack” on page 43.
The switch assigned module ID number 1 will be the master switch of the
stack.
There are two ways to assign module ID numbers to the switches of a
stack. You can assign the numbers yourself or you can let the
management software do it automatically when it performs the discovery
process of the stack. Numbers that you assign are called static module ID
number because they do not change even when devices are added to or
removed from the stack. Numbers that are assigned by the management
software are called dynamic module ID number because they are based
on the MAC addresses of the units and can change as the composition of
a stack changes.
The commands for managing the module ID numbers are SET STACK
and SHOW STACK. The SET STACK command should only be used
when a switch is functioning as a stand-alone device, because changing a
switch’s module ID number when the unit is part of a stack can have
unpredictable results.
If you decide to assign static ID numbers to the switches of your stack,
continue with the next procedure to number and label the units.
If you choose to use dynamic module ID number, skip to “Cabling the
AT-StackXG Stacking Modules” on page 62.
For more information on module ID numbers, refer to Chapter 1,
“Overview” in the
AT-S63 Stack Command Line Interface User’s Guide .
