Which of the following protocol works on layer 2?
TCP/IP Protocol Architecture Model
| OSI Ref. Layer No. | OSI Layer Equivalent | TCP/IP Protocol Examples |
|---|---|---|
| 4 | Transport | TCP, UDP |
| 3 | Network | IP, ARP, ICMP |
| 2 | Data link | PPP, IEEE 802.2 |
| 1 | Physical | Ethernet (IEEE 802.3) Token Ring, RS-232, others |
How many network layer protocols are there?
seven layers
The OSI Layers The OSI reference model organizes a network into seven layers (a protocol stack). These layers define how networking hardware and software are to hand data and transfer it across a network.
What is a Layer 2 service?
A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Both methods use a standard MPLS header to encapsulate data.
What are some Layer 3 protocols?
The protocols used in Layer 3 include:
- Internet Protocols IPv4/v6.
- Internet Control Message Protocol (ICMP)
- Distance Vector Multicast Routing Protocol (DVMRP)
- Internet Group Management Protocol (IGMP)
- Address Resolution Protocol (ARP)
- Internet Protocol Security (IPsec)
- Routing Information Protocol (RIP)
Is DHCP a layer 2 protocol?
DHCP belongs to application layer i.e. layer 7 of OSI model. The Dynamic Host Configuration Protocol is a standardized networking protocol used on Internet Protocol . It is a popular method of assigning IP address to a network.
What are Layer 2 network devices?
LAYER 2 NETWORKS Devices used on a Layer 2 Ethernet network include network interface cards, hubs, bridges and switches. Ethernet devices use ‘burned in’ MAC addresses to identify each host. These addresses are attached to network interface cards and cannot be changed.
What is Layer 2 support?
Generally, Layer2 product support includes consulting, troubleshooting, and problem resolution related to evaluation, licensing, purchasing, operation, and update / upgrade of our products.
What is Layer 2 data called?
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer.
