Managing Switch Stacks
This chapter provides the concepts and procedures to manage Catalyst 3750-E switch stacks.
The switch command reference has command syntax and usage information.
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 5-25
• Displaying Switch Stack Information, page 5-25
• Troubleshooting Stacks, page 5-25
For other switch stack-related information, such as cabling the switches through their StackWise Plus
por
ts 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 hardware and software stacks and about using universal software images with software
licenses, see the Cisco IOS Software Installation 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 one switch type in a stack, or you can connect a mix of
Catalyst 3750-X, Catalyst 3750-E, and Catalyst 3750 switches in the stack. Catalyst 3750-X and
Ca
talyst 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 or a Catalyst3750-X-only stack with only Catalyst 3750-X switches as stack members.
• Mixed stack
– A mixed hardware stack with a mixture of Catalyst 3750-X, Catalyst 3750-E, and 3750 switches
as stack members.
For example, a stack with Catalyst 3750-E and 3750 switches supporting the IP services
