No...the physical layer is just that: The wires or COAX or fiber that physically makes up your network. If the switch were to work at a physical layer it would literally be opening or closing contacts to make the wires joined together be disconnected or connected...which is NOT the case, there is no physical opening/closing going on.
Switches I was trained on (in the mid-80's) worked based on MAC addresses of devices, that unique only-this-one-device-in-the-world number burned into end units. Or there is a possibility they might work higher up the protocol chain, on the Ethernet Address. it's been too long since I was involved with zeros and ones. But certainly not on the physical layer. Hopefully someone with more recent experience will update this answer for you...
Layer 1 - the physical layer
Ethernet switch fits on osi physical layer
physical layer Layer 1
hub work at physical layer of osi model
layer 3 layer 3 Switch/ Bridges / Hubs works at layer 2 as they utilizes MAC address to communicate. However i aggree above stated answer as there are some layer three switches that work at Layer3 i.e. Network Layer. Dhruv
TheHub work on layer 1 i.e. Physical layer of OSI Model
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
Its at Layer 1 of the Open Systems Interconnection Model (OSI model) Layer 7 Application Layer 6 Presentation Layer 5 Session Layer 4 Transport Layer 3 Network Layer 2 Data Link Layer 1 Physical
1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.
It is a layer 3 switch
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
