I did some research, and found that I'm probably creating a loop between the devices. &nbsp;I also found that I could use Link Aggregation between switches to increase throughput.<br />
<br />
My question now becomes 1.) Am I right on what I've found, and 2.) Can I setup Link Aggregation on unmanaged switches because all of my switches are currently unmanaged (and the Dell 2716 is the only one that can be in managed mode).<br />
<br />
Thanks again,<br />

Hi, I work for a small company current with 1 router, 1 wireless access point, and 4 switches on a gigabit Ethernet network.<br />
<br />
I recently learned about the performance increases associated with a parallel backbone. &nbsp;so, I ran a crossover cable between the switch downstairs and the main switch upstairs. &nbsp;In both instances when I connected the cable, all the clients lost both LAN and WAN connectivity.<br />
<br />
Why do the network clients lose connectivity when I attempt to implement a parallel backbone (run multiple crossover cables) between two network devices (switches and routers)?<br />
<br />
This is my first question on Experts-Exchange, so if more information is necessary, please let me know.<br />
<br />
Thanks,<br />

Network Clients Lose Connectivity With Parallel Backbone

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.

Network Architecture

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

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.
