Hi,<br />
&nbsp; &nbsp;I have 2 switch cisco 3750 cluster. I want to make a 4 switch cluster i.e add two new 3750. <br />
I was doing this while the switches remained on. All switches have the same ios installed in there flash + they were provisioned. The cabling currently is switch 1 stack 1 goes to switch 2 stack 2 <br />
switch 1 stack 2 goes to switch 2 stack 1. <br />
<br />
My target is the attached. Also please confirm if this is correct layout??<br />
<br />
To do with the switch connected <br />
the first move i made was i moved stack2 on switch 2 to stack 1 to switch 3 <br />
the switch 3 came up no problems pulled the config and is now part of the stack done a sh switch everything was ready and fine. <br />
<br />
The next move i made was on switch 3 i cabled stack 2 to stack 1 on switch 4. <br />
<br />
Switch 4 would not come into the stack it just kept saying that it was waiting for peer <br />
<br />
Any ideas am i going about this correctly <br />

Cisco 3750 install of 2 switch into cluster

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
