It is a layer 3 switch
I believe there is no such thing as switching "from layer 3 to layer 2". Switching is either done within layer 3, or within layer 2.
because one layer is the electrical part, and the other layer is the place where the switch is on.
A layer 2 switch uses the MAC address to determine which port to switch the frame out of.
A Switch is a Layer 2 device as they operate in the data link layer
There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
Layer 2.
Depending on the IOS on the switch it will have either layer 3 functionality (EMI) or just layer 2 functionality (SMI).
a high grade layer 2 switch can be used to access local resources but will not be suffice to access the internet you would need a layer3 switch to access remote resources
Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
A layer 2 switch at it's core only forwards data within a LAN and only deals with MAC addresses. A layer 3 switch has the capability of forwarding frames and packets because it understands IP addresses.
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
