Why do we need VLAN interface?

Why do we need VLAN interface?

These VLAN interfaces are virtual interfaces and can be pinged as well as provide the connection point for remote management. This IP address can only be used as the default gateway on a multilayer switch. A VLAN (Virtual Local Area Network) is its own logically segregated broadcast domain.

What does interface VLAN mean?

A VLAN Interface is a virtual interface that is attached to the physical network port or bond that your VLAN is configured on. The VLAN Interface is used to automatically tag traffic that is routed through it with the appropriate VLAN ID.

What is difference between VLAN and SVI?

VLANs reduce the load on a network by keeping local traffic within a VLAN. An SVI interface can be created for each VLAN that exists but only one SVI can be mapped to each VLAN. An SVI is virtual and has no physical port defined and performs the same functions for the VLAN as a router interface.

What is the purpose of a sub interface?

A subinterface is a virtual interface created by dividing one physical interface into multiple logical interfaces. A sub-interface in a Cisco Router uses the parent physical interface for sending and receiving data. Subinterfaces are used for a variety of purposes.

Is it possible to Ping the vlan interface?

08-04-2019 08:34 PM This is going to be a beginner level question, however I cannot seem to find the answer anywhere. I have the following (relevant) configuration/status: Very simply, my laptop (10.0.0.3 255.255.255.0) is connected directly to fastethernet0, however I cannot ping the vlan10 interface (10.0.0.10).

How can I test if my Switch is connected to a VLAN?

This test can be done either on the switch itself or by the hosts which are connected to their respective VLANs. Use a extended ping command by using the source address from an SVI interface you’ve created towards the IP address of the another SVI on this switch.

What are the ports of a VLAN on SW1?

I’ve set up two VLANs on SW1 and associated two ports to each VLAN. Each VLAN has one HOST-PC connected to it. I have also designated port 23 (Fa1/0/23) to be the trunk port going to the router. On the router I setup port 8 (fastEthernet 8) as the trunk port going to the switch. I then created two sub-interfaces 8.10 and 8.20.

Why do I need a VLAN X interface?

Having a single interface vlan x will allow management access to the switch and will allow the switch supervisor to access other network resources. It will not have any impact on layer 2 forwarding or on layer 3 forwarding.
