vlan is l2 or l3?

A L2 switch does switching only. This means that it uses MAC addresses to switch the packets from a port to the destination port (and only the destination port). ... Practically this means that a L3 switch is capable of having IP addresses and doing routing. For intra-VLAN communication, it uses the MAC address table.

A virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this context virtual refers to a physical object recreated and altered by additional logic.

ADSL2 is the older standard and maxes out at 22mbps down per stream. Loop lengths are longer and it's a bit more tolerant of line issues. VDSL is a newer standard and maxes out at 100mbps down per stream, depending on loop length. Distance from the DSLAM is much more important, but speeds can be much higher.

A VLAN is helpful for organizational use mainly because it can be used to segment a larger network into smaller segments. ... VLANs can help reduce IT cost, improve network security and performance, provide easier management, as well as ensuring network flexibility.

No, VLANs don't require different subnets. Different subnets require different subnet addresses if they ever need to be able to route and/or talk to each other) and by extension if one VLAN wants to talk to a different VLAN it must use different addresses so we can make a routing decision to the right place.

VLANs address issues such as scalability, security, and network management. Network architects set up VLANs to provide network segmentation. Routers between VLANs filter broadcast traffic, enhance network security, perform address summarization, and mitigate network congestion.

How Does VXLAN Work? VXLAN is often described as an overlay technology because it allows you to stretch Layer 2 connections over an intervening Layer 3 network by encapsulating (tunneling) Ethernet frames in a VXLAN packet that includes IP addresses.

A VLAN is an Ethernet level concept, a subnet is an IP level concept. A VLAN splits an Ethernet network into multiple logically seperate Ethernet networks. ... It is common practice to have a 1:1 mapping between subnets and VLANs but it is perfectly possible to have multiple subnets on the same VLAN.

The data link layer (Layer 2) of the OSI model actually consists of two sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The MAC sublayer controls device interaction. The LLC sublayer deals with addressing and multiplexing.

By default, all Layer 2 control traffic is associated with VLAN 1. A native VLAN is assigned to an 802.1Q trunk port. Trunk ports are the links between switches that support the transmission of traffic associated with more than one VLAN.

After all, most of us think in terms of IP addresses, not MAC addresses. Both subnets would then reside in VLAN 300. ... Takeaway: Your switches won't warn you if you have multiple subnets using a single VLAN. Never assume a VLAN has only one subnet.

All VLANS work fine across the router to ping each other, but I think I have some fundamental flaw about how to use gateways that is stopping machine in VLAN10 from pinging machine in VLAN20. ... Given the above, do you mean the gateway for the vlan10 PC should be 192.168. 1.254 and 192.168.

VLANs use software to emulate separate physical LANs. Each VLAN is thus a separate broadcast domain and a separate network. ... However, it is completely permissible to use the same RFC1918 subnets on different physical networks. You could likely even make all the addresses the same.

In a layer 2 VPN, L2 frames (usually Ethernet) are transported between locations. In the more general case, it's similar to a cable connecting two switches in separate buildings. ... In a layer 3 VPN, each side of the connection is on a different subnet, and IP packets are routed through the VPN.

The LAN used for voice traffic from the IP phone is called the voice VLAN and the VLAN used for data is called the data or access VLAN.
