What should the native vlan be

Native Vlan. Dear All, I just wanted to know" wat is native vlan where it use. Brajagopal Tripathi likes this. I hope the scheme will help. This can causes issues: If the native VLANs on the two associated switch ports are not the same, the received traffic without a VLAN tag will be assumed to belong to the receiving port's native VLAN, which will lead to mis-directed traffic.

Several others have mentioned that it's "untagged", meaning does not apply Why would you do that? First: consider this to be the year , Let's assume you have a link between two switches.

To use mljevakovic 's diagram, say the link between the top and the bottom-left switch. Ok, cool, it's a trunk port with several VLANs, and the switches in mljevakovic 's diagram understand that. For discussion, let's say I add a new device into that link between the two "smart" switches. This new devices makes no distinction about frame format, and doesn't care if the frame is It will simply forward all frames to all ports, like the switches from the mid's.

Not great, but it will work. If I attach a PC to that new switch, it will receive all frames. However, it has no idea what to do with the Even if the frame was intended for the PC. Also anyone having dirtect access can attempt a DOS attack and prevent you getting into your own kit. Meraki kit uses an encrypted outbound stream to the Meraki cloud. So I don't personally bother with a seperate management network.

You can also disable the Meraki local status page to further protection. If this is of a concern you should use a different native VLAN on trunk ports between switches.

For safety, this should be a VLAN not in use in the network. You want every valid VLAN to be tagged between switches. PhilipDAth So if I change my default vlan to Followup 2 I may have answered my own question - Hmm actually all I care about on this network is it having access to the default VLAN so I can access all my wired infrastructure. From your comments above you seem less vigilant about that and if its fine as is Id rather not change it.

Having a default VLAN of 1 means you can easily do things like a factory reset a Meraki device or replace a piece of hardware and do nothing more than plugging it back in again. If something "odd" is going on, the odds are the perps will use VLAN 1 as an egress. Not using VAN 1 makes it easier to monitor attempts to penetrate the network. Uberseehandel but ok to have the switches hanging out on vlan 1, nothing more, yes?

And if I did NOT want it to join that subnet, the next thing would be to configure the port it connects to only pass one VLAN's 4 in this case traffic to make sure it got the right subnet's lease? All other ports should be configured as an access port, and an access port can only be in a single VLAN at a time.

It is more secure to avoid using VLAN 1 for anything. Uberseehandel Ok. So lets say I change it to 8. I will need to add 8 to all my trunk ports on switches, but because its called Default does that mean that all my APs will automatically move to it? Thats what Im trying to figure out. It doesn't matter what the default network is, avoid using it. The entire concept of a default value is insecure, inherently.

You don't need a default VLAN. If you need to enter a VLAN value, when it is not required, use think about it. Always reference VLANs explicitly, not generically.

Individually declare the VLANs to be passed by a trunk port. Thank you both. Ok - thanks for going slow with me here. How does one define the "management VLAN"? Is it the VLAN labelled default? What makes it so? Uberseehandel OK I think I figured it out. Tell me if I got this right. Did i get the right idea though?? What you are proposing looks very like what I have, so I suggest you proceed. Most end-devices PCs, printers, etc. Having a native VLAN would allow end-devices to connect to an interface configured as a trunk.
