Managing Switch Stacks
This chapter provides the concepts and procedures to manage Catalyst 3750-E switch stacks.
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.
This chapter consists of these sections:
•Understanding Switch Stacks, page 5-1
•Configuring the Switch Stack, page 5-20
•Accessing the CLI of a Specific Stack Member, page 5-24
•Displaying Switch Stack Information, page 5-24
For other switch stack-related information, such as cabling the switches through their StackWise Plus
ports and using the LEDs to display switch stack status, see the hardware installation guide.
Note This chapter describes how to manage Catalyst 3750-E-only switch stacks. For information about
managing mixed hardware and software stacks and about using universal software images with software
licenses, see the Cisco Software Activation and Compatibility Document on Cisco.com.

Understanding Switch Stacks

A switch stack is a set of up to nine stacking-capable switches connected through their StackWise Plus
or StackWise ports. You can connect only Catalyst 3750-E switches in a stack, or you can connect both
Catalyst 3750-E and Catalyst 3750 switches in the stack. Catalyst 3750-E stack members have
StackWise Plus ports, and Catalyst 3750 members have StackWise ports. The stack can have one of these
configurations:
•Homogeneous stack—A Catalyst 3750-E-only stack with only Catalyst 3750-E switches as stack
members.
•Mixed stack
–
A mixed hardware stack with Catalyst 3750-E and 3750 switches as stack members.
For example, a stack with Catalyst 3750-E and 3750 switches supporting the advanced IP
services features.
