Cisco 3750 switch stack configuration points 3750 stack is a real stack, the Catalyst 3550 series uses StackWise technology, it is an innovative stack architecture, A 32 Gbps stack interconnection is provided to connect up to nine switches and integrate them into a unified, logical, and optimized device for convergence, in this way, customers can deploy voice, video, and data applications with greater confidence. 3750 adopts the backplane stack mode. The machine itself has a stack port and requires a dedicated stack line to achieve 32 Gbit/s bandwidth, after the switches are stacked, logically, 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 other switches in the stack (3750 requires a dedicated stack cable for stacking, the product comes with 0.5 m stacked cables ). Www.2cto.com I. basic requirements: the ios version should be consistent, the dedicated stack module and stack cable, the maximum number of stacks 9 II. Stack advantages: high-density ports for ease of management (a switch is displayed during configuration, with different slot numbers) III. Stacked instances: 1: physically connected stacked cables, the connection method is master stack1 connected to slave stack2. 2: enable the master without any configuration. . 3: Server Load balancer is enabled. 4: No configuration is required. (After the cables are inserted, automatic stacking election is started, and master is highlighted) Note: Stack configuration can also be performed first: for example, IP address, priority, and so on www.2cto.com 4. Check the current stack status: show platform stack-manager all show all switch stack information show switch display stack switch summary information show switch 1 display switch 1 Information show switch detail display stack Member details information show switch neighbors show switch stack-ports show complete port information of the stack switch. Note: 1. The model can be different, but the version must be the same. 2. It is best to operate under power failure, but the live operation can also be performed. 3 and 3750 cannot be stacked with 3550.
