What is L2 and L3 testing?

Different types of network Protocols (L2 and L3) Layer 2: It is a data link layer. Mac address, Ethernet, Token Ring, and Frame Relay are all examples of Data link layer. Layer 3: It is a network layer that determines the best available path in the network for communication. An IP address is an example of layer3.

What is L2 L3 development?

This training involved the testing & Development of protocols or programs which are used in devices like: routers, switches, PCs, modems etc. protocols are used for communication between different layers of OSI models. So in datacom industry protocol testing refers to the testing L2 & L3 protocols.

What is L3 protocol?

The main functions of Layer 3 include routing and forwarding, as well as internetworking, addressing, packet sequencing, congestion control and further error handling. The protocols used in Layer 3 include: Internet Protocols IPv4/v6. Internet Control Message Protocol (ICMP)

What is protocol level testing?

Protocol Testing is a method of checking communication protocols in the domains of Switching, Wireless, VoIP, Routing, etc. The primary goal of protocol testing is to check the structure of packets which are sent over a network using protocol testing tools.

What is Layer 2 testing?

Layer 2 Ethernet switches forward traffic, also called net- work frames, across various network segments. Forwarding is based on information in the frame’s Ethernet header. After the equipment is deployed in live net- works, existing equipment can be retested in the lab using the same RFC-based test tools.

What is difference between L2 and L3?

Layer two networks forward all their traffic, including ARP and DHCP broadcasts, so data transmitted by one device on L2 will be forwarded to all devices on the network. Administrators on L3 can segment networks and restrict broadcast traffic to subnetworks, limiting the congestion of broadcast on large networks.

What is L2 or L3 switch?

A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers. That means, a Layer 3 switch has both MAC address table and IP routing table, and handles intra-VLAN communication and packets routing between different VLANs.

What is L2 and L3 in networking?

Commonly known as L2/L3 device or multi-layer switch (L2 = Ethernet, L3 = IP). To simply put it, an L3 switch is a combination of an Ethernet switch and IP router.

What is the difference between network layer 2 and 3?

A Layer 2 switch only works with MAC addresses and doesn’t interact with any higher layer addresses, such as an IP. A Layer 3 switch, on the other hand, can also do static routing and dynamic routing, which includes IP and virtual local area network (VLAN) communications.

What RFC 2544?

RFC 2544 is the Industry-standard service activation test for single-service Ethernet and IP (i.e. “pipe test”). The test measures key performance indicators and bandwidth profile such as: throughput, latency, packet Jitter, frame loss, and committed burst size (CBS).
