Chapter 2: Virtual Chassis Stacking

Switch ID Numbers

74
Each switch must be assigned an ID number. The range is 1 to 8 for a
stack with a trunk of AT-StackQS modules or the S1 and S2 ports. The
range is 1 to 4 when the stack trunk consists of the 1Gbps front panel
ports. The default is 1. The ID numbers are displayed on the ID LEDs on
the front panels of the units. You may assign the numbers yourself or let
the master switch assign the numbers automatically when you initially
power on the stack.
You use the ID numbers to identify the individual ports and switches when
you configure the devices with the commands in the management
software. For further information, refer to "Specifying Ports in the
Command Line Interface" on page 76.
The ID numbers are also used to identify the parameter settings that are
stored in the configuration file. When the stack is reset or power cycled,
the ID numbers identify the devices to which the parameter settings
belong.
Caution
You should not change the ID numbers of the switches after you
start to configure the parameter settings. Otherwise, the parameter
settings might be applied to the wrong devices when you reset or
power cycle the stack.  E79
The switches do not use their ID numbers to select the master switch. The
selection of the master switch is based on their priority numbers and MAC
addresses, as previously explained.
