Ethernet fabric primer What is an Ethernet fabric? An Ethernet fabric is a type of network topology that collapses traditional three-tier data center switching architectures into one or two tiers, ensures network traffic is never more than two hops away from its destination and operationally behaves like one big switch.

What is Cisco FabricPathâ¦ and why should you care about it? FabricPath is based on the TRILL standard – with a few Cisco bonuses – which builds on the concept of “what if we could route a layer 2 packet instead of switching it.” Under the covers of FabricPath it uses the ISIS protocol, a MAC encapsulation, and routing tables to achieve all of the magic.riginally I was worried about having to learn a completely new protocol, but the truth is that most of us already know all of the concepts that make FabricPath work. Think about routing to the access layer and why we like that design. 1  Routing protocols truly eliminate spanning tree.

Ethernet frame Ethernet frame. A data packet on an Ethernet link is called an Ethernet packet, which transports an Ethernet frame as its payload. An Ethernet frame is preceded by a preamble and start frame delimiter (SFD), which are both part of the Ethernet packet at the physical layer. Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields.

History of Network Interface Cards Ethernet is a standard that enable two or more computer to share information and communicate. Ethernet network, also known as local area network (LAN), connects computers which can transfer data at the speed of 10Mbps or more. Since its invention, Ethernet standard has evolved a lot. Improved media access control methods, alternate physical medium and higher bandwidth are some of examples of evolution.

ARCHIVED: What is Ethernet? Ethernet (the name commonly used for IEEE 802.3 CSMA/CD) is the dominant cabling and low level data delivery technology used in local area networks (LANs). Following are some Ethernet features: 1  Ethernet transmits data at up to ten million bits (i.e., 10 megabits) per second (10 Mbps). 2  Fast Ethernet supports up to 100 Mbps, Gigabit Ethernet supports up to 1,000 Mbps, and 10 Gbps Ethernet supports up speeds matching its name (10 gigabits per second or 10,000 Mbps).

An Ethernet Primer If you ask a bona fide network engineer how Ethernet works, he'd say something like this: Using MAC addresses to distinguish between machines, Ethernet transmits frames of data across baseband cables using CSMA/CD.. This is an accurate description, and after we go over all the concepts in it, it will even make sense.

What the fex is a FEX anyways? This is a quick, high level rundown of Cisco’s various fabric extender technologies and where each fits into the data center. A Fabric Extender (FEX for short) is a companion to a Nexus 5000 or Nexus 7000 switch. The FEX, unlike a traditional switch, has no capability to store a forwarding table or run any control plane protocols. It relies on its parent 5000/7000 to perform those functions.

What is Ethernet? A NIC is installed in each computer and is assigned a unique address. An Ethernet cable runs from each NIC to the central switch or hub. The switch or hub will act as a relay (though they have significant differences in how they handle network traffic), receiving and directing packets of data across the LAN.
