i THINK packets may be sent to the supervisor plane for forwarding, i found this:<br />
<br />
&nbsp;Forwarding architecture: These modules use the central Cisco Express Forwarding engine located on the supervisor engine.<br />
• Forwarding performance: These modules forward packets up to 30 Mpps per system and up to 15 Mpps per slot if upgraded to support distributed forwarding.<br />

Hi there,<br />
<br />
As far I read on official Cisco website, the 48 ports 10.100.1000 line card WS-X4448-GB-RJ45 is made of 6 groups of 8 ports each connected to 1Gbits trunk to Supervisor.<br />
<br />
What if I have 4 servers, so 4 ports, in the same vlan, same subnet, connected to the same group of 8 ports. Those 4 servers need to communicate at 1Gbits rate between eachother. Does the traffic goes up to the supervisor, so I would have 250mbits per server ? or the local traffic stays in the group on the local card and everybody got 1gbits ?<br />
<br />
Thx for your answers!<br />
<br />

WS-X4448 uplink trunk

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

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.

Telecommunications

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.
