Switch Id Numbers - Allied Telesis AT-x550-18XTQ Installation Manual

Switch ID Numbers

Each switch in a stack has to have a unique ID number. The numbers are
displayed on the ID LEDs on the front panels of the units. The possible ID
numbers depend on the version number of the AlliedWare Plus
management software. The ID numbers are 1 and 2 for the two switches in
a stack with AlliedWare Plus v5.4.7A-0, and 1 to 4 for the four switches in
a stack with AlliedWare Plus v5.4.8-0.2 or later. The default is 1.
You use the ID numbers to identify the individual switches and ports when
configuring the devices with the commands in the management software.
For further information, refer to "Designating Ports in the Command Line
Interface for Stacks" on page 48.
The ID numbers are also used to identify the parameter settings of the
switches in the configuration files. When the stack is reset or power
cycled, the master switch uses the ID numbers to identify the devices to
which the parameter settings belong.
Caution
You should not change the ID numbers of the switches after
configuring the parameter settings of the stack. 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 the ID numbers to select the master switch. The
selection of the master switch is based on their priority numbers and MAC
addresses, as explained in "Selection of the Master Switch" on page 71.
