This category includes our L2 Ethernet and L2 Ethernet plus other protocol courses.  The courses in this category are 100% Instructor Led either in person at your site or a site close to you, or via Online meeting tools such as Zoom, Microsoft Teams, Google Meet, HP Rooms, or Webex.

A strong understanding of Layer 2 Ethernet is essential in today’s Internet and broadband environments because:

  • Ethernet is the universal transport technology underlying nearly all modern networks
  • Most traffic (Wi-Fi, fiber, cable, data center) is encapsulated in Ethernet frames at some point
  • Core concepts like VLANs, trunking, MAC addressing, and switching control traffic flow
  • Enables diagnosis of Layer 2 issues such as broadcast storms, loops, and VLAN misconfigurations
  • Requires understanding how Ethernet interacts with IP, transport protocols, Wi-Fi, MPLS, and security
  • Supports cross-layer troubleshooting to isolate issues across physical, switching, routing, and application domains

L2 Ethernet in a Day - 1 Day ILT

Ethernet was invented as a Local Area Network protocol that busted the ceiling of bandwidth at the time (1980's).  Today Ethernet is more than a LAN protocol.  It runs in metropolitan networks, and even as a Wide Area Network service.  Having hands-on experience configuring and observing how Ethernet, VLANs, and Ethernet switching works is crucial in operating a network today.  This swift, one day, 8 hr. class uses a "follow me" learning approach to build skills, the student will get a clear understanding of Ethernet at Layer 2.
