Introduction to Cisco 3750 switch Stack

The 3750 stack, unlike the 3550 stack, is a real stack. The Catalyst 3750 series uses StackWise technology and is an innovative stack architecture that provides a 32 Gbps stack interconnection, connect up to nine vswitches and integrate them into a unified, logical, and optimized device for integration, so that customers can deploy voice, video, and data applications with greater confidence, 3750 uses the backplane stack mode. The machine itself has a stack port that requires a dedicated stack line to achieve 32 Gbit/s bandwidth. After the switch is stacked, logically speaking, they belong to the same device. In this way, if you want to configure these switches, you only need to connect to any device, and you can see that other switches in the stack 3750 need dedicated stack cables for stacking, the product comes with 0.5 m stacked cables ).

I. Basic Requirements:

The ios version must be consistent.) Dedicated stack modules and stacked cables, a maximum of 9 stacked cables.

Ii. Stack advantages:

A switch is displayed for high-density ports to facilitate management and configuration, and the slot number is different)

Iii. Stack instances:

1: The stacked cables are physically connected. The connection method is master stack1, which is connected to slave stack2.

2: enable the master without any configuration. .

3: Server Load balancer is enabled.

4: No configuration is required. Line plug, automatic stacking election upon startup, master is highlighted)

Note: You can also configure stacks first, such as IP addresses and priorities.

4. Check the current stack status:

Show platform stack-manager all displays information about all swap stacks

Show switch: displays the summary of stack switches.

Show switch 1 displays vswitch 1 Information

Show switch detail: displays details of stack members.

Show switch neighbors: displays the complete information of stack neighbors.

Show switch stack-ports: displays the complete port information of the stack switch.

5. Notes

1. The model can be different, but the version must be the same

2. It is best to perform power-off operations, but it is also possible to perform power-off operations.

3. 3750 cannot be stacked with 3550
