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. …

Does native VLAN need IP address?

You don’t even have to configure an IP address, and actually, you shouldn’t. Essentially what this does is if any frames are sent to this interface with no VLAN tag, they will be processed by this interface. This interface essentially goes nowhere, so any frames coming here would be dropped.

What is VLAN number?

Why do we create VLAN?

A VLAN allows different computers and devices to be connected virtually to each other as if they were in a LAN sharing a single broadcast domain. A VLAN is helpful for organizational use mainly because it can be used to segment a larger network into smaller segments.

What is native VLAN?

native vlan means that device will never put/insert tag (VLAN ID, in you case “VLAN ID:2”) on Ethernet frame when it leaves port and also when Ethernet frame without tag go into that port device will put/insert tag defined by native vlan ( in you case VLAN ID:2). Of course native vlan relates to trunk port.
