It might help you would with your timeout issue.

Thank you for you response. <br />
<br />
so if I disabled it, the port will authenticate one time, right ? <br />
<br />
if the machine connected to that port ( already authenticated), will the port disable the port until it will authenticate again ?

Thank you for you response.

<div>
Yes if it is disabled it will only auth one time.

Yes if it is disabled it will only auth one time.

Hummm,<br />
<br />
thank you, you answered my first question.<br />
<br />
but I think my second question was not clear.<br />
<br />
I meant will the switch authenticate one time per machine (connected to port) or one time for all machines connected to that port ?<br />
<br />
thank you again.

What does ReAuthEnabled on Dlink switch mean?

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

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.
