How does a layer 2 switch work in a network?
Layer 2 switch provides a fast speed data transmission in a network because its each port breaks the large collision domain. Each port have its own collision domain. Layer 2 switch forward frames from one device to another. A router decide to forward or drop the packet on the basis of PUD attached with packet.
Is there a routing algorithm for Layer 3 switches?
There is no routing algorithm followed by these types of switches. Whereas the Layer-3 Switches follow the routing algorithm, and the data packets are destined to the next defined hop and destination host is rooted on the defined IP address in the receiver’s end.
When does a redundant link create a switching loop?
The redundant or backup link is helpful only when the primary link fails. Until the primary link is functioning, the backup link should be disabled. If both the primary and backup links are active at the same time, they will create a switching loop. Let’s take an example.
When does a switching loop occur in a network?
Redundant / Backup Link (S1, S4, S5, S6) This network will function smoothly only if one link either the primary link or the backup link is active. If both links are active, a switching loop will occur. And, due to the switching loop, this network will not work.

Layer 2 switches, operating at the Data Link layer, can be programmed to respond automatically to a wide range of circuit conditions. By monitoring control and data events, these switches automatically reroute circuits or switch to backup equipment, as the need requires. These switches operate using physical network, or MAC, addresses.
What’s the best way to set up an Ethernet connection?
To set up an Ethernet connection, start by getting an Ethernet cable that you can connect to your computer and router. Next, make sure your router is connected to your modem and that the router’s “online” light is on. Then, locate the Ethernet port on your computer, which is typically a square port with an icon showing a series of boxes, and on
How does IP multicast work at Layer 2?
IP Multicasting at Layer 2 makes use of this ability to transmit IP Multicast packets to a group of hosts on an LAN segment. IP Multicast frames all use MAC layer addresses beginning with the 24-bit prefix of 0x0100.5Exx.xxxx. Unfortunately, only half of these MAC addresses are available for use by IP Multicast.
Where do I plug in an Ethernet cable to my computer?
Just check the back of your router for a ethernet port. Plug a ethernet cable (this should have come with the router), into your pc or laptop. The PC might have a port. If not, then you can add a ethernet card yourself.
