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.
There are no layer 1 switches; switches run at layer 2 or 3. A hub is a layer 1 device.
Yes. Most switches (which operate at layer 2) will NOT route packets between different subnets. However special layer 3 switches DO have this capability.
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Application specific integrated circuitMPLS
On a packet switched network, data travels between layers 1, 2 and 3 of the OSI model using routers (layer 3), switches (layer 2), and media (layer 1).
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.
It operates on the data link layer of the OSI model (level 2). The switch creates a separate collision domain for each port. Although some switches operate on level 3 of the model and are called multi-layer switches.
layer 3 switches require ip address but hub do not require
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
a router and a layer 3 switches.
Yes, a switch can perform the functions of both a bridge and a router, but it typically requires specific types of switches. Layer 2 switches act as bridges by connecting devices within the same network segment and forwarding frames based on MAC addresses. Layer 3 switches, on the other hand, can route packets between different networks using IP addresses, thus combining the features of both a bridge and a router. However, traditional switches do not have routing capabilities unless they are specifically designed as Layer 3 switches.
Routers and layer 3 switches work at Layer 3 of OSI model.
