How Ethernet Switches Work: Terms And Functionality Ethernet switching involves many complex terms and processes. Let’s break these concepts down one by one: Packet switching is a networking technology that switches use to forward data frames through a network based on their destination address, ...
Ethernet II frames are the most common types of frames and are generally used by the IP protocol. Figure 4-3 shows the Ethernet II frame format. Figure 4-3 Ethernet II frame format An Ethernet II frame has the following fields: DMAC: destination MAC address, which specifies the receiver of...
An aggregate interface might receive frames larger than 1536 bytes during high-throughput data exchanges, such as file transfers. These frames are called jumbo frames. How an aggregate interface processes jumbo frames depends on whether jumbo frame support is enabled on the interface. · If configu...
Jumbo frames are frames larger than 1536 bytes and are typically received by an Ethernet interface during high-throughput data exchanges, such as file transfers. The Ethernet interface processes jumbo frames in the following ways: · When the Ethernet interface is configured to deny jumbo frames ...
At initial startup, Ethernet bridges work somewhat like Ethernet repeaters, passing all traffic between segments. By observing the source addresses of incoming frames, the bridge then builds an address table associating addresses to segments. Once an address is learned, the bridge forwards network ...
Devices that work at this layer are routers and Layer 3 switches. ▪ Data link layer This layer is responsible for delivering frames between NICs on the same physical segment. Communication at the data link layer is generally based on MAC addresses. The data link layer wraps data from the ...
(Note that this doesn't mean that higher-level protocols will work on this network without effort—just Ethernet itself.) All of the Ethernet protocols belong to the IEEE 802.3 series and are based on the idea of encoding frames. A frame is a well-defined packet message, with a source, ...
How Does PPPoE Work The PPPoE process operates in two main stages: the Discovery Stage and the Session Stage. The Discovery Stage – Establishing the Session Before data can be transferred, a PPPoE client (your router or computer) needs to locate and establish a connection with a PPPoE server...
How these frames are routed through the network is no longer automatically determined, but rather configured by software. This combination of multicast MAC and VLAN ID is called the stream ID and all TSN frames with the same stream ID are called the TSN stream. A TSN stream always has just...
To do that, they needed something that would work no matter which LAN technology was in use. Because there was no guarantee that all LAN frames would have a type field, the IEEE 802 committee provided the LLC protocol as a method of identifying the type of data being carried by the ...
