Is it possible to connect two VLANs?

The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.

Can a switch port have multiple VLANs?

You can create multiple VLANs on the Switch. By default, you can assign One Access Vlan (Data) and One Voice vlan on the switch port.

Can two VLANs have the same IP address?

The OSA-Express Layer 2 implementation allows the hosts to manage IP addresses and ARP cache, so it is possible to have a single guest LAN segment (or VSWITCH segment) where two different hosts use the same IP Address on different VLAN groups.

How do you communicate between two different VLANs in a switch?

There are three methods of permitting traffic to flow between VLANs:

  1. Configure a router and connect a single interface to a switch per VLAN configured.
  2. Configure a router to use IEEE 802.1Q and connect to a switch via a trunk.
  3. Configure (and possibly purchase) a Layer 3–capable switch.

How do I configure two VLANs on one port?

If you want TWO VLANs to be accessible on that port, you can configure it as a trunk and assign both VLANs to the port and the downstream device will need to be able to make use of VLAN tagging. Additionally, you can set the “native” VLAN on the port so that it will also still accept untagged traffic.

Can layer 3 switch route between VLANs?

Capabilities of a Layer 3 switch include the ability to do the following: Route from one VLAN to another using multiple switched virtual interfaces (SVIs).

How many VLANs can be on a switch?

Creating a VLAN NOTE: A switch supports a maximum of 4096 VLANs, among which VLANs 0 and 4095 are reserved for system use, and VLAN 1 is the default VLAN. Therefore, you can only create VLANs 2 to 4094.

Can a host belong to 2 different VLANs?

The figure also shows that a single host can also belong to more than one VLAN. For example, Host A has two VLANs configured over the host’s interface. The second VLAN is configured with the VID 456 and is connected to Port 3 which is also configured with the VID 456.

How many VLANs can you have on a switch?

A switch supports a maximum of 4096 VLANs, among which VLANs 0 and 4095 are reserved for system use, and VLAN 1 is the default VLAN. Therefore, you can only create VLANs 2 to 4094. You can repeat the vlan command multiple times.

Can you have 2 VLANs on the same subnet?

Of course you can do that, but it is not the recommended way. VLANs use software to emulate separate physical LANs. Each VLAN is thus a separate broadcast domain and a separate network. As you have identified, routing between these VLANs would be difficult, because they are the same subnet.

Can you ping across VLANs?

If your switch has L3 ability, you can issue the ip routing on the global config and then use the ping. Also the L3 communication between VLAN interfaces (as known as SVI on Cisco literature) starts to work. This test can be done either on the switch itself or by the hosts which are connected to their respective VLANs.

What is difference between L2 VLAN and L3 VLAN?

I answered them, Layer 2 VLAN is a single broadcast domain. It works on layer 2 (Datalink Layer). They can communicate only within it. And L3 VLAN is an Interface, that works on Network Layer.
