RT,3750G可以和3750X组成堆叠吗,是不是只要IOS版本一样就可以,与设备型号关系不大?

应该是支持的
在3750x的config guide中提到statck的模式分为两种,Homogeneous stack(同型号堆叠)、Mixed stack(混合堆叠)
在混合堆叠中又分了几种:不同硬件、不同ios feature、软硬皆不同的堆叠。
我只截取了介绍部分,具体配置方法,可以参考配置文档中其余部分。
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 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 or a Catalyst 3750-X-only stack with only Catalyst 3750-X switches as stack members.
  • --Mixed stack

Note Mixed stacks are not supported with switches running the LAN base feature set.


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 3750-X and 3750 switches supporting the IP services features.
A mixed software stack with only Catalyst 3750-X, only Catalyst 3750-E, or only Catalyst 3750 switches supporting different features as stack members.
For example, a Catalyst 3750-E-only Catalyst 3750-X-only stack with some members running the IP base feature set, other members running the IP services feature set, and the remaining members running the IP services feature set.
A mixed hardware and software stack with Catalyst 3750-X, Catalyst 3750-E, and Catalyst 3750 switches supporting different features as stack members.
For example, a stack with the Catalyst 3750-E 3750-X members running the IP services feature set and the Catalyst 3750 members running the IP services software image.
For information about Catalyst 3750 switches, see the “Managing Switch Stacks” chapter in the Catalyst 3750 Switch Software Configuration Guide.
One of the switches controls the operation of the stack and is called the stack master. The stack master and the other switches in the stack are all stack members. The Catalyst 3750-E Catalyst 3750-E stack members use the Cisco StackWise Plus technology to work together as a unified system. Layer 2 and Layer 3 protocols present the entire switch stack as a single entity to the network.

Note Switch stacks running the LAN base feature set do not support Layer 3 features.


In a mixed stack that has Catalyst 3750-X, Catalyst 3750-E, and Catalyst 3750 switches, we recommend that a Catalyst 3750-X switch be the master and that all stack members run Cisco IOS Release 12.2(53)SE2 or later. The Catalyst 3750 image is on the Catalyst 3750-X and 3750-E switches to simplify switch management.
To upgrade the stack, use the archive download-sw privileged EXEC command to download images to the master. For example, use the archive download-sw /directory tftp://10.1.1.10/ c3750-ipservicesk9-tar.122-55.SE1.tar c3750e-universalk9-tar.122-55.SE1.tar command to specify a directory, following the command with the list of tar files to download for the members.

  • The c3750-ipservicesk9-tar.122-55.SE1.tar is for the Catalyst 3750 members.
  • The c3750e-universalk9-tar.122-55.SE1.tar is for the Catalyst 3750-X and 3750-E members.
You can display the file list that is in the flash memory:
Switch# dir flash: c3750e-universalk9-tar.122-55.SE1Directory of flash:/c3750e-universalk9-tar.122-55.SE1/ 5 -rwx 14313645 Mar 1 1993 00:13:55 +00:00 C3750e-universalk9-tar.122-55.SE1.tar6 drwx 5632 Mar 1 1993 00:15:22 +00:00 html443 -rwx 444 Mar 1 1993 00:15:58 +00:00 info444 -rwx 14643200 Mar 1 1993 00:04:32 +00:00 c3750-ipservicesk9-tar.122-55.SE1.tar
The stack master is the single point of stack-wide management. From the stack master, you configure:

  • System-level (global) features that apply to all stack members
  • Interface-level features for each stack member
A switch stack is identified in the network by its bridge ID and, if it is operating as a Layer 3 device, its router MAC address. The bridge ID and router MAC address are determined by the MAC address of the stack master. Every stack member is identified by its own stack member number.
All stack members are eligible to be stack masters. If the stack master becomes unavailable, the remaining stack members elect a new stack master from among themselves. The switch with the highest stack member priority valuebecomes the new stack master.
The system-level features supported on the stack master are supported on the entire switch stack. If a switch in the stack is running the IP base or IP services feature set and the cryptographic (that is, supporting encryption) universal software image, we recommend that this switch be the stack master. Encryption features are unavailable if the stack master is running the IP base or IP services feature set and the noncryptographic software image.

Note In a mixed stack, Catalyst 3750 or Catalyst 3750-E switches running Cisco IOS Release 12.2(53)SE and earlier could be running a noncryptographic image. Catalyst 3750-X switches and Catalyst 3750 and 3750-E switches with Cisco IOS Releases later than 12.2(53)SE run only the cryptographic software image.
