Let’s summarize the above:

  • layer 1 switches are not capable of intelligent data processing — they only transmit electrical signals. At present,...
  • layer 2 switches identify devices by MAC addresses and transmit frames of information between strictly defined senders...
  • layer 3 switches work with IP addresses and not just identify senders and recipients, but build optimal...

What is a Level 2 switch?What is a Level 2 switch?

A level 2 switch forwards information by MAC address of the network card. It keeps an onboard database of all the directly attached machines MAC addresses of their NIC cards.

Which are Layer 1 switches?

  • The easiest way to think of a Layer 1 (L1) switch, also known as a physical layer switch, is as an electronic patch panel . Completely transparent connections between ports is performed based on software commands sent to the L1 switch over its control interface.

What is the main function of a layer 2 switch?

  • The main function of a Layer 2 is to help the traffic from devices within a LAN reach each other. A Layer 2 switch does this by keeping a table of all the MAC addresses it has learned and what physical port they can be found on.

What is access layer switch?

  • Access layer switches facilitate the connection of end node devices to the network. For this reason, they need to support features such as port security, VLANs, Fast Ethernet / Gigabit Ethernet , PoE , and link aggregation.
