Is a subnet the same as a VLAN?
At a high level, subnets and VLANs are analogous in that they both deal with segmenting or partitioning a portion of the network. However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network.
Does a switch need a subnet?
No, switches are not just simplified routers. Switches create networks, routers connect distinct networks together. Switches operate using only MAC-addresses, while routers also use IP addresses. Switches have many ports in the same subnet, while routers can only have one port per subnet.
What is the difference between a switch and a VLAN?
With a VLAN, each port on a switch can be configured into a specific VLAN, and then the switch will only allow devices that are configured into the same VLAN to communicate. In this configuration, the traffic between groups would be prevented at Layer 2 because of the difference in assigned VLANs.
What is the difference between a VLAN and a subnet?
However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network. Although it’s a common practice to create a one-to-one relationship between a VLAN and subnet,…
Do subnets and VLANs serve the same purpose?
VLAN allows us to create different logical and physical networks. Subnet allows us to create logical networks through the same physical network. A VLAN is configured at server/router side. The one who controls the router/server decides which computer/port is assigned to which VLAN.
Can two VLANs on the same subnet?
Each VLAN represents only one subnet, so when you say VLAN it is the logical meaning of a subnet ID, so let me give another definition. So, for example, Subnets 10.1.1.0/24 and 10.1.2.0/24 can’t be on the same VLAN, they have to be in 2 different VLANs, and to enable communication between different VLANs, there are 3 options.
What is a non-routable VLAN?
A non routeable VLAN is simply a normal VLAN that lacks a router, thereby not being routable to other networks. One common use of non-routable VLANs is for storage networks.
