Chapter 6: Building the Trunk with Default Stacking Ports 17 and 21

Introduction

126
This chapter contains procedures for building the stack using the stacking
ports 17 and 21. The procedures do not require any configuration steps
because the stacking feature is enabled by default and ports 17 and 21
are the default stacking ports. To build the stack, you cable the stacking
ports and power on the switches.
As explained in the following procedures, the assignments of the switch ID
numbers are determined by the manner in which you power on the
devices:
 To control the assignment of the switch ID numbers yourself,
perform "Powering On the Switches Individually" on page 127. The
numbers are assigned in the order in which you power on the units.
 To have the switches assign the ID numbers automatically, perform
"Powering On the Switches Simultaneously" on page 130.
Caution
Do not change the switch ID numbers after beginning to configure
the parameter settings of the stack. Otherwise, the stack might
assign configuration settings to the wrong units.
Note
To use the optional stacking ports for the stack trunk instead of the
default ports, refer to Chapter 7, "Building the Trunk with Optional
Stacking Ports" on page 143. For background information, refer to
"Stack Trunk" on page 54.
