Switch work in which layer of osi modle?
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
Router is a layer 3 or 4 device if your ans is layer 3 then while applying an extended access list on router interface how specifying port no is aloud as it comes under layer 4 protocols?
A router is a layer 3 device.In general, a Layer-3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities. A router is a Layer-3 device that simply do routing only. In the case of a switching router, it is primarily a router that may use switching technology (high-speed ASICs) for speed and performance (as well as also supporting Layer-2 bridging functions). As illustration, here are some examples Layer-2 switches Cisco: Catalyst 2950, 2960 series Layer-3 switches or routing switches Cisco: Catalyst 3550, 3560, 3750, 4500, 6500 series Juniper: EX series Routers (with some bridging and/or security features) or switching routers Cisco: 1800, 1900, 2600, 2800, 2900, 3700, 3800, 3900, 7200, 7600, ASR 1000 series Juniper: MX series, J series, M series
What does ip routing enabled mean?
Enabling routing on a layer 3 switch.
What layer of the OSI model is a Switch on?
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.
Which of the following is considered a Layer 2 device?
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.
What is the cost of a Cisco 2950 switch?
The cost of a Cisco 2950 switch can range from $78 to over $1,000. It all depends on whether you choose to buy a new Cisco 2950 switch or a refurbished one.
Cisco 1900 series a layer 3 switch?
Very much not.The 1900 series is a very old switch that does not even run a normal IOS. Its successor, the 2900XL series, does run an IOS. The 2900XL series' successor, the 2950 series, still does not support layer 3 routing. For layer 3 functions, you need Cisco 3550, 3560, or 3570 series switches.
What is another term for a layer 3 switch?
router operates on Layer 3 and can be used as a switch
Ws-c3560-24ps-e is layer 2 switch or layer3 switch?
It is a layer 3 switch
Will a Cisco 4000 switch automatically switch from layer 3 to layer 2?
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.
What is diff between layer 3 switch and router?
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
Where can one purchase a Layer 3 Switch?
A layer 3 switch is used like a router. Places where a layer 3 switch can be purchased include the Cisco website, Amazon, eBay and Central Computers. The happyrouter website provides comparisons and further information.
Which of the following OSI layers does a Layer 3 switch operate at?
network layer
