And best practice is to terminate individual links to different switches in a stack.

ok &nbsp;thanks.<br />
<br />
in my stack I have two uplinks.<br />
One uplink per switch device, is it right ?

<div>
Yes. &nbsp;Or two, or four. How many depends on how many ports the switch has and how much bandwidth you need. <br />
<br />
The reason behind connecting to multiple switches in the stack is for redundancy in case a switch fails.

<div>
ok thanks.<br />
<br />
can you give me also an example for the commands ?

ok thanks.

can you give me also an example for the commands ?

<div>
ok thanks,<br />
<br />
when I configure the uplinks to a port channel...<br />
...do I loose connection ?<br />
<br />
Is it better to do the change not at working hours ?

for a short time I lost connection &nbsp;but just some settings.<br />

Thanks to all of you.

Hi Experts,<br />
<br />
My core switch is a C3650X and I have connected 2 Stacks of 2960X.<br />
I have 2 uplinks to each stack.<br />
<br />
Is it possible to create a port channel with the uplinks ?

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.
